Re: Why Linux Developers Should Reconsider IBM Mainframes - Linux.com
Now that I think about it, I don't think there was ever an i390 -- although there was an i370, which died a long time ago (based on the very first port of what was then not yet z/Architecture, s390 took its place when IBM decided it'd participate in GNU tools development way back circa 2000/2001. s390x (z/Architecture) was introduced almost immediately after s390 came on board, and it seems to be the ID "with legs". In modern terms, i390 means nothing (unless someone would care to revive it), s390 means XA, s390x still means z/Architecture as it always has. You're right. The s390x tag isn't used much outside of GNU/Linux & BSD circles. Too bad. I think it's a very convenient shorthand (not to mention 10 characters' less typing to do), YMMV :-) Jim Tison z/TPF Systems Programmer IBM Services From: Rob van der Heij To: LINUX-390@VM.MARIST.EDU Date: 10/13/2019 11:50 Subject:[EXTERNAL] Re: Why Linux Developers Should Reconsider IBM Mainframes - Linux.com Sent by:Linux on 390 Port But it’s true that those terms are not used outside Linux on System Z.

Re: cio_ignore vs Linux in System z
It's also about efficiency. Recall that there aren't many other processors out there whose I/O architecture is built on (sub)channels. If the cio_ignore data indicates that signals arriving from certain channels needn't be processed, then that's less work the kernel has to engage in. In cases where the assignment of devices has been done in an imprecise manner, cio_ignore can be a godsend, allowing you to blacklist all devices except those which you know your machine uses. If cio_ignore is bothering you, it's rather easily dealt with -- you just have to remember to do it. See https://www.mail-archive.com/linux-390@vm.marist.edu/msg61591.html for an earlier (brief) discussion of practical living with cio_ignore. If you don't have any devices worthy of blacklisting, then just set up your kernel parm line to omit the cio_ignore specification altogether.

Re: DB2 db2start command for Linux on System z
What's in your PATH variable? On my system, /home/db2instance_name/sqllib/adm/db2start is the location of that command. You'll need to know the name of the db2instance, mine is (most unimaginatively) db2inst1. Your mileage may vary. Look for it and make the proper substitution. I think you'll need to make PATH point there and to a couple other places DB2 likes to find things. I'd do this: export db2inst=/home/db2inst1/sqllib export PATH=$PATH:$db2inst/adm:$db2inst/bin:$db2inst/misc Creating the variable db2inst just makes for less typing, you don't have to do that; you could just do all the typing.

To me, it's not about security -- it's about keeping the CP directory and the RACF database in sync, which DIRMAINT will do with RACF as long as you leave the suggested user exits in place.

Re: Root filesystem error switches to ReadOnly
I guess one thing that would be wrong then is that I copy from the live system. I think that's your problem. You're copying from a likely unstable source (the live system might be writing to your volume as you attempt to copy it). Try shutting down the master (live) system with shutdown -h now before you copy from it. The errors you're reporting look like file system structural errors.

Re: How can I get an assembler definition of a structure?
Sorry, Ben. As far as I've ever known, you cannot get such a listing from either gcc (this information is thrown away prior to assembly, except for debugging) or as. The closest thing you can get is a DWARF-3 description through DIEs (Debug Information Entries). It's roundabout, but it's the only way I know of. 1. Compile your program with -g 2. You'll need a program called dwarfdump. It's available in the libdwarf package, you'll probably need to download and build it. 3. Where your program is named myprog, run dwarfdump -i myprog | less To find the first structure definition, search forward for DW_TAG_structure_type. The struct you seek will have a DT_AT_name of task_struct. DW_TAG_member items are your members' identifiers. The information is a little dispersed, but it's usually there and obvious. Offsets from the start of the aggregate are expressed by DW_AT_data_member_location values within the DW_TAG_member block. It will look bizarre at first, but you'll get used to it. If you're curious about this data and its format, it's described in the Dwarf-3 specification.

Re: RHEL source control packages
Of course you can!! CVS is easy. Building svn from source is a much different story -- critical dependencies on Apache, ART, yadeyadeyada -- not all systems are properly equipped. Been there, done that -- it's a pain. But if it were me putting up a better CVS, I'd think twice and reconsider Subversion, especially if available in binary/RPM form -- tagging is unnecessary, and branching is almost second nature.

Those files are established by the kernel, and their permissions are fixed, in my experience. Trying to sync such a file is hopeless. Allow the kernel on the target machine to live with its copies. If it were me, I would exempt at least /sys and /proc from your rsync list. The reason why is that these files are kernel instrumentation, with custom-supplied internal I/O service functions.

I've had just *one* bad AMD chip in the past (not bad for as many as I've bought) which actually behaved once I cut its multiplier down to below spec; but all the rest of the failures I've seen have been power supply-related (sigh, even Antec).

Re: X-compile build
IIRC, crt{n,i,0}.o are built in glibc. If I didn't want to go through
cross-building glibc, I'd just: transfer all these from a real s390x
machine to the place where your cross binutils/gcc expects to find them.
But if you want a full cross-development environment, you'll need a glibc
anyway: you could transfer all that, too, but why deprive yourself of the
fun of a full cross-build from scratch? :-)

Re: Which profile file is read on z/Linux?
Can't agree more with all of the posters who've advised you to stay out of /etc/profile and pointed you to /etc/profile.d and similar directories. This directory nest might seem disoriented at first. I can't agree any more strongly with John's recommendation, either. In this circumstance, z/Linux is no different than the rest of the Linuces. The Linux Standard Base (LSB ... refer to http://www.linuxbase.org) defines the minimum requirements for shell initialization. Both SuSE and Red Hat conform, so you're safe on either of those platforms (as you'd be on most of the other distros, too) if you assume the /etc/* directories with effects on shell init exist. As you decide as to how to implement your feature(s), you might want to refer to the LSB and conform. Otherwise you might find yourself implementing a solution whose validity might disappear over time ... or with your next system maintenance update ... or worse. Unfortunately, many products existed or were in development before LSB: they're only now starting to do the right thing. It's going to take some time before all the software houses get it implemented across their product lines.

Re: Generating and fstab from list of mounted file systems
Looks to me that /etc/mtab contains the most complete information.
The only thing it doesn't show is swap and the values of fs_freq and
fs_passno (those last two numbers in the fstab) and that can be figured
out
by rule vs actual. root getting 1 1 the rest getting 1 2 and the thigns
like sysfs and proc by rule are 0 0.
Are there things like compound variables in the bash shell? Kinda like
stem
variables in rexx ? Something that can be declared and indexed through so
that var.1 = /dev/dasda var.2 = {mountpoint} var.3 = fs type and so on?
If that's possible in the bash shell then the administrivia of creating
the

bash shell script, so I'm not sure and someone walked off with my book.

Re: Any caveats moving root filesystem to LVM?
The one caveat I'd lay out is: DON'T. There are only a couple of arguments pro, and zillions of arguments con. The con argument that carries the most weight with me is that you can recover from most any other disk disaster _except_ the corruption of your root device. As has been suggested, I make all of the 1st level subdirectories separate mount points, and place their contents on non-root devices (LVMs, even!!). I only keep the directories needed for booting (/etc, /bin, /sbin, /boot, /lib ... CAUTION: this list might not be complete!! I'm working off the top of my head...) on the root device. Once you've done this, you won't have any reason to make your root device LVM -- it will turn out to be very manageable in terms of size. If you wanna use that extra space on the root device, go ahead and partition it, and give partition 2 over to LVM for use. Bottom line: there are a few disaster cases where having your root device LVMed would make your system unbootable. I haven't sat down to count them all, but they exist. I use LVM for everything except the root disk. LVM has lots of value for allocations that exceed physical device bounds: a well-administered root device isn't one of them. As to the quality of LVM overall: backup your filesystems with filesystem-independent tools (like tar, Amanda, TSM, etc). Do not trust disk surface in the long run: it _can_ go bad, LVM or not. LVM just adds one more layer of potential data scrambling ... never a good thing when you're up to your waist in a disaster. LVM works very well, and I've found it so far to be very reliable (2 years in service now); but you don't want to deal with that extra layer in a disaster context, and you gain nothing from putting a well-thought-out root device under LVM control.

Re: How to restrict memory/CPU for certain users
There's also getrlimit() setrlimit() (replacements for the obsolete ulimit()), which are supposed to work, but do not in all cases. If you've got PAM on your system (as my SLES 8 box does), you can set /etc/security/limits.conf ... the PAM stack is supposed to (and does, BTW) call setrlimit() to set the limits.conf-resident values applicable to the uid/gid before the userspace program gets control. I find it very effective at limiting nproc, for example (to stop runaway fork() loops), but I haven't found a way that _works_ to enforce userspace memory limits. I can only guess that there must be certain back doors to memory allocation that bypass checks on these limits, because I still get a runaway process (usually user-written test-level code) every now and then that will try to suck up every byte of memory in the box -- CRASH. I started looking for these back doors, but then work intervened. :-( This sounds like the facility you're looking for -- its design permits control by users groups (or everyone, if you like) -- it just doesn't allow for controls on a per-program basis, which would be okay with me. Now, if it only worked 100% of the time ... sigh. I'm hoping for better in kernel series 2.6.x. The good Mr. Cox didn't even mention this. Is the facility _that_ crippled? Or is Apache just calling setrlimit() in the cited cases? I could describe the symptoms of a fatal run on memory ... most of us have probably seen them ... but I'll spare us all the blood and gore for now.

You can alter its time-based dispatch in /etc/cron.d/sysstat (probably ... if not there, then in one of the /etc/cron* directories).

Re: Newbie: Transferring data from Linux to mainframe
Product? You don't need no steenking product. (Sorry, Americanism from Hollywood) You just can't get those tape labels that MVS seems to thrive on. Here's what I would do in your position, assuming that data_producer_pgm is the output I want to record and convert: export BLKSIZE=1024# or whatever you want mt -f /dev/tape rewind # make sure youre at blk 0 data_producer_pgm | iconv -f ISO-8869-1 -t IBM1047 | \ dd -bs=$BLKSIZE /dev/tape mt -f /dev/tape offload# clear tape for next guy If data_producer_pgm is something inane like 'cat', then just skip that step and name the file as input to iconv. The -f and -t operands of the iconv command may differ, depending on what the source and target character sets are. If there's any binary data in the output, DON'T USE iconv. You'll have to write an application-specific translator instead. I seem to recall many years ago that there used to be a TRTCH option in MVS that did ASCII-EBCDIC translation; but it was hardware dependent, and I see that it's now gone from my copy of the JCL Reference. The output blocksize of the tape is going to depend on how you write to it, so I've put a 'dd' step in the middle that reads and writes in the blocksize of your choice (default input = stdin, default output = stdout, perfect for piping), as the example shows, just for insurance. You won't have labels, so you _have_ to furnish DCB information to MVS when you process over there. When you take the cartridge over to MVS, mount it as no label. If you really gotta have labels, you can put them on in MVS with an intermediate IEBGENER job before you process the tape on the MVS side, like so: //JOBNAME JOB account,etc //ADDLABEL EXEC PGM=IEBGENER //* SYSUT1 came from Unix: no labels. //SYSUT1 DD UNIT=tape,LABEL=(1,NL),DCB=(DSORG=PS,RECFM=FB, //LRECL=1024,BLKSIZE=1024,TRTCH=NOCOMP),DISP=SHR //* SYSUT2 is the copy all MVS jobs will use from now on. //* Make it MVS-friendly (add labels, give it a DSN, and catalog) //SYSUT2 DD DSN=tape.dsn,UNIT=whatever,DCB=(either.copy.or, //change,your.choice),DISP=(,CATLG,UNCATLG) //SYSINDD DUMMY WARNING: the ability to process unlabeled tapes is often restricted by RACF. If you work in one of these shops, get the admin to lift this restriction for at least you. I added a TRTCH parameter to the SYSUT1 DD because I have no clue what kind of tape hardware you'll be assigned on the MVS side -- this might be unnecessary; but it can't hurt. ANOTHER WARNING: I haven't had to do this in at least 10 years. My memory could be a little rusty. Let me know how this works for you. If you're reading this tape on VM/CMS, just let CMS TAPE do its thing -- it works tapemark-to-tapemark, just like Unix tape processing does, and couldn't care less about labels. --Jim-- James S.

Re: Newbie: Question about porting applications to linux on z series
Welcome to the list. If the application truly contains no architecture-specific code, and makes no assumptions about the size of int as opposed to the sizeof int*, for example, you only need to recompile; whether it's for s390 (32-bit words, 31-bit addressing) or s390x (64-bit words and addressing). Casting into ints also gets sticky in s390x, but, in general, if it's well-written C/C++ code, it should just port (and in general, just work) with no sweat. Of course, I can count the well-written programs I've seen in my 22 years working with C on both hands; but if you've got one, it should port very well. Pointer arithmetic is defined by the C/C++ language(s). As long as you don't try casting addresses into ints and operating on the int, you're ok. Your questions make perfect sense. Give your port a shot, and see what happens. The first thing I always do is just try to compile it, and then see what errors warnings pop up. Sometimes well- written code isn't as well-written as we'd think, and it needs a little correction to be LP-64 operable. --Jim-- James S.

Re: Did some extensive hipersocket testing/benchmarking.... need help interpreting results.
I fear I'm gonna start a flame war here, but here goes anyway. WARNING: I am NOT speaking for IBM here ... this is all personal experience. I also want to apologize in advance for the length of this post. Network bandwidth is measured point-to-point. Leland's test using netpipe is probably the best indicator of what this _theoretical_ maximum is. Network bandwidth is always stated _independent_ of IP stack processing time and other interference factors. Gigabit Ethernet means that the maximum transmission rate that the NIC can handle is 1000 Gbps (that's bits, or 125 MB[ytes]ps). Like any other I/O method, you can't go any faster than your most restrictive bottleneck will allow. FTP is a __TERRIBLE__ benchmark. Remember that besides network bandwidth, other factors that might introduce latency are things like OS scheduling delays/timeslicing on both client and server ends, disk I/O delays on both ends, etc; _not_to_mention_ TCP SYN/ACK traffic, possible retransmissions, packet fragmentation and reassembly, etc. A better but much more complicated way to test if you can't afford (or author) benchmarking software The two peers you test with have _got_ to have ZERO routing hops between them: routing can also introduce latency; but with hipersockets, this isn't supposed to be an issue. You may not think that a typical LAN routing latency of 4-6 ms is a big deal, but the more packets that get sent (and ACKed), the more _any_ latency will hurt your final net throughput value. We're talking about possibly thousands of packets, and nK * X ms = seconds, at least. The fastest way to the IP stack that I know of without going raw is ICMP (ping). You can adjust the ping packet size to a value close to and below the lowest MTU size of each of the two peers (you don't want fragmentation involved, either, and IIRC, even large ICMP packets will fragment), then set flood ping mode, and let 'er rip. Some peers will refuse to run flood mode ... the VM TCPIP peer I have a PPP connection with inserts a 200 ms interval, so you cannot use the total time reported at the end, but the averages work. In these cases, you need to run an adaptive ping (-A) instead of a flood (-f). Here's how this works: I figure the maximum packet size to be the MTU - 20 (IP header) - 8 (ICMP header) - 8 (ICMP_ECHO_REQUEST). This works out to 1456 for me. Here's what I get with my VCTC connected VM TCPIP peer, with my MTU set at 1492 on a brand-spanking new z/990 running z/VM 4.4: ping -A -c 100 -s 1456 9.10.11.12 snip --- 9.10.11.12 ping statistics --- 100 packets transmitted, 100 received, 0% loss, time 20788ms rtt min/avg/max/mdev = 0.159/0.224/0.344/0.043 ms I can't use time 20788 ms as reported: there's 200 ms of interval inserted by the peer for every ping. So instead, I can calculate total time as rtt avg (0.224 ms) times the packet count (100), to yield 22.4 _milli_seconds, or 0.0224 seconds. Since this is round trip (rtt), I can divide this by 2, yielding 0.0112 seconds. The total data transmitted was 1492 bytes X packet count (100), yielding 149,200 bytes. The effective bandwidth calculation now works out to 149,200 --- = 13,321,428 B/sec 0.0112 (note the big 'B': that's bytes, not bits. Little 'b' is supposed to mean 'bits', but this convention isn't always followed) 13,321,428 / (1024 X 1024) = 12.70 MB/s This is a NET figure, and it really doesn't look stellar, does it? IP stack time in and out is still being measured. So we repeat this test with a minimum packet data size (-s 16, yielding a total packet size of 52 bytes), and we get: rtt min/avg/max/mdev = 0.128/0.196/0.456/0.061 ms That's 5,200 -- = 518 KB/s 0.0098 Big difference, huh? But if we look at these measurements out of context, we're gonna scratch our heads, much like the first inquirer did. We need to look at them _comparatively_ to figure out what the _delta_ is between the two transmission rates. That is, (Where Blarge = bytes xferred in large packet test, Bsmall = bytes transferred in small packet test, Tlarge = time consumed in large packet test, and Tsmall in small packet test), which measures the effective bandwidth, or the rate at which _additional_ data is transferred, effectively removing the IP stack interference factor: Blarge - Bsmall --- = Absolute bandwidth Tlarge - Tsmall Which yields, in my case: 149,200 - 5,200 --- 0.0112 - 0.0098 144,000 --- = 102,857,142 B/sec 0.0014 ... or 98 MB/sec (or 784 Mbps, however you wanna look at it). Absolute bandwidth is the actual transmission speed, in-pipe. It can be reduced by other traffic sharing that same pipe with you as you test. I just ran this test a few minutes ago, in the midst of a production day, which isn't an accurate or wise

SuSE SLES 8 SP3 (kernel 2.4.21-107)
We just upgraded from base SLES 8 (kernel 2.4.19-3) to SP3. We noted is the tape module configuration change. We hand- wrote a sysinit script to modprobe tape390, and now an implicit insmod for tape_3590 fails. Sure enough, the new modules.dep lists two modules: tape_3590 and tape_3590_mod with the main tape driver (kernel/drivers/s390/char/tape390.o) as the sole dependency for each. True to form, lsmod shows nothing so named as loaded, and an attempt to attach a 3590 fails to register the device. No I/Os issued against /dev/ntibm0 work when we attach a 3590, but all I/Os (and the contents of /proc/tapedevices) work for 3490 devices. When I try to cd into the directory with tape_3590.o and tape_ 3590_mod.o in it and issue insmod against either or both, I get flooded with unrecognized symbol messages ... I guess these don't match the kernel. The new initrd doesn't have/load any modules that would affect the tape* chain. Any ideas where I might be bumping my head? Fix? TIA, --Jim-- James S.

Re: REXEC revisited
Crispin, From your description, you're counting on the CMS guest to be able to execute the name resolver, then open a socket to the Linux rexecd host. This all sounds so simple that I wonder if something critical in your VM configuration didn't change when you went to z/VM 4.4. Perhaps the global DIRMAINT user profile changed to omit profile TCPPROF, or similar? I'd suggest you post this on a VM specialty list somewhere. I am able to run the REXEC client from my CMS guest right to the Linux guest running on the same VM LPAR. I have absolutely no idea what's required to make this work; but I just wanted to let you know that it *does* work on a properly configured z/VM 4.4 LPAR. One very reliable alternative I know of depends on the privilege class of the (ex-)rexec client, or its secondary user status relative to the Linux machine (assuming same VM LPAR). You could use CP SEND command text here if your sender has class C privilege. If your sender has class G, it needs to be SECUSER. If the client server are on different z/VM LPARs, I'm not sure how to handle this. Peace, --Jim-- James S.

Oh. __VM__ ... I'm sorry, I mis-read you. I thought you had a Linux complaint. There is an REXECD disconnected virtual machine that should be running in order to provide the rexecd function on VM.

Re: What should glob() return for .*/..
Nope, it's not there. SUS refers to this capability indirectly, via the XCU specs for file expansion. AFAIK, the name of the GLOB_PERIOD flag is probably unique to the GNU implementation -- other implementations may call this flag/functionality something else. The fact that it's optional is pretty much a death sentence for it in the z/OS UNIX implementation: it's not their common practice to implement more than the minimum function required to pass the Open Group's UNIX branding suite. --Jim-- James S.

Re: Linux for zSeries 31 bit/ 64 bit
1. Is it possible to run s390x software on s390 Linux? Never. There is no 64-bit compatibility mode library or kernel support. 2. Do your paths need to point to specific places to develop s390 software under s390x compatibility mode? No. BUT ... you may need to apply one or more -m command line options to your gcc/g++ compilation link steps. I find that -m31 is all that's needed. 3. Do you ever need to point to 32-bit (s390) libraries? Never. The s390x kernel with compatibility mode makes all of the runtime which libraries do I need? decisions for you with no intervention on your part. It works for just about all binary distributed packages (with one notable exception: UDB/DB2) I've ever tried to install. For development purposes, if you seek to emit AMODE=31 code linkages, use the -m31 switch on all your compilation linkage steps. When linking, be certain any dynamic or static libraries you want to link with were created with 32-bit word size. There is no distinction made between AMODE and RMODE like there is on z/OS: it's either all 32-bit words (and AMODE=31 addressing and instructions, called ELF32 format), or 64-bit format, called ELF64. The compiler knows which libraries to point at during its link phase as long as compatibility mode is installed. I suggest you have a look at info gcc for further details on this subject. Most of what I've ever done with s390 software development on an s390x platform has only required the -m31 switch to emit perfect s390 ELF32 executables. You may find some exceptions to this rule if you try to port other people's code, and you cannot write s390x kernel modules as ELF32 objects. The gdb (debugger) I run on my s390x machine will not recognize ELF32 modules ... for that reason alone, if I were developing applications for ELF32 deployment, I'd do so on an s390 machine, unless you're really comfortable with your code :-) Maybe you could build a cross-debugger like you can a cross-compiler (???); but I've never been desperate enough to try it.

Re: Linux and buffers and memory allocation
I used to fight this one all the time too: I was convinced that the harm induced by paging-related VM I/O waits was killing machine performance. It was, before I discovered VDISK units for paging. I was just about always in Q3 waiting I/O response from one of my (then-) real paging minidisks, even under conditions of very light memory load stress. I changed my paging units to VDISK, and now whenever I find myself in Q3, it's for a better reason (waiting on TCP/IP, or even real disk I/O). Someone posted a link to a PDF document produced by Red Hat with sysctl tweaks for RHEL 3, which (despite not being even 50% relevant for me) I'll admit was a very valuable discussion that shed some more light on Linux paging file caching for me, at least. But under VM, it doesn't matter as much to me as it would if I were running LPAR. Here, I'd trust the counsel of my VM guys before I'd start tweaking sysctls. Under LPAR, I'd have no choice other than to tweak or suffer. If you don't trust Linux to make page/fs cache decisions, try letting VM do it through VDISK. I'd try this before I start risking the stability of my system with radical sysctl tweaks. When I did it, I went all the way: I now have 1.1 GB page space on VDISK and zero on 3390-x, which backs 768 MB main memory. Current average load pressure says I'd be doing very little paging at about 1 GB main; but every now and again I get a runaway process that changes the phrase memory stress to paging frenzy, and the machine still recovers from frenzy-induced runqueue loads as high as 34.0 as long as the memory pig is found and slain before too much time goes by. My load (interactive developers) sounds very different from yours; but if paging- related waits are your problem, try VDISK. It might help you out, if your VM guys will let you use it.

Re: Installing SP3 on SLES8
Mike, About the only way I can think of is to create a 2nd image of your machine, and see if the updates work there. This is difficult if you're running on an LPAR/native, but easy if you're under VM. We took this approach. We did find some changes in the tape drivers that didn't trickle down into our initrd, so we had to modify that, and once that was done, SP3 was fine on the test machine. It will go into our production machine very shortly. As far as I can tell, once you've applied the SP3 RPMs to the kernel, there is no turning back. Much unlike Red Hat's upgrade philosophy, your fallback components are deleted in the update process. --Jim-- James S.

New (first) FBA device - dasd_fba_mod not loading
Got a head-scratcher that perhaps a lister can help me with here. We installed a sandbox copy of SLES 8 as a VM guest. During installation, there were no VM VDISK units (FBA) attached to the machine. We added one for swap space, extended parmfile /etc/zipl.conf to include the new address, hoping that the subchannel scanner would sense it during IPL and insert the dasd_fba_mod module. No go. If I insmod dasd_fba_mod by hand, all is fine; but shouldn't this be automatically sensed? Or have I missed a script setting somewhere? My production system did have VDISK units attached at installation time, and they're automatically sensed quite beautifully after the ECKD units get sensed and collected. Any ideas?

Re: developers require older version of c++ lib on 2.4.xx system
Rich, I don't think you can get away with that. Kernel 2.4.19 sounds like you're running SLES 8, which comes with gcc 3.2. The gcc folks specifically changed the C++ ABI at either 3.0 or 3.1. I'd suggest your developers recompile their application and go from there. What matters here isn't the kernel level, but the level of the gcc/g++ compiler. When we cutover to SLES 8 from ThinkBlue 7.1a (gcc-2.95 ???), most everything in the house we had (including C programs) that was custom-written had to be recompiled. Fortunately, that didn't take long and there were no serious barriers that I can recall. --Jim-- James S.

Re: New Linux User
Hi Mike, /dev/dasda (major 94: minor 0) is reserved three partitions on it: /dev/dasda1 (94:1), /dev/dasda2 (94:2), and /dev/dasda3 (94:3). Same scheme for all the other physical DASD --- the minor value that mod 4 returns zero on is the unit itself, the other three are its partitions -- these aren't optional. So if you have 91 physical devices, /dev/dasdcm looks correct as your last device (with its three partitions, /dev/dasdcm1, /dev/dasdcm2, and /dev/dasdcm3). But I only have 37, so what would I know? :-) Most sysadmins have their DASD units emulating 3390-3s, with a capacity of approximately 2.3 GB per unit. 91 DASD units makes for a pretty darned large system. Basic DASD unit /dev/x names never have numbers in them, their partitions always do. Vic already showed you the mknod command, and Mark (thanks again) already gave you the major:minor pairs to use for each. Nobody says you HAVE to partition your DASD (see man fdasd); but I've always put partition tables on mine just in case I want to split the disk up later. You can also do that with LVM, but let's just stick to the basics now since you're new. Make one partition (for example, /dev/dasda1) on each physical DASD. You're going to need to make the system decide how to mount them onto your filesystem. File /etc/fstab should have a series of mount-like commands (see man mount and man 5 fstab) that force DASD partitions to uniquely correspond to points in your filesystem tree at which each partition will be mounted. You can then put a filesystem on each of your partitions as you please. ext3 is probably the most commonly used, but there are others available. Have a look at man mkfs if you want an idea of what this entails. 91 units way exceeds what most basic installation programs will format, partition, and mount up for you unless you spend hours entering in device labels mount points during initial installation. Starting off with a jumbo system like you have is rarely a good idea if you used the standard installation program and have never done this before. My guess is that you could have as little as 1 DASD unit mounted on /, with all the other mount points on that single DASD unit. Then you'd have 1 unit in use and 90 sitting there doing nothing. File /etc/fstab will tell you. The df command will give you a hint what you're using, too. Your first DASD unit/partition (/dev/dasda1) should have mount points /etc, /bin, /sbin, /boot, and /lib on it, at minimum -- your parmfile (in /boot/zipl on SuSE) should have root=/dev/dasda1 in it, too ... this is the device you'll IPL. If you didn't understand those last three paragraphs, keep reading very basic Linux/Unix books until you do. I have no idea _how_ new you are to all this -- I hope I haven't insulted you. IBM's ITSO website has got lots of Redbooks you can read about implementing Linux under VM, natively, or LPARed. Welcome, by the way. --Jim-- James S.

Not necessarily: they are dynamically allocated (presumably nobody got around to getting a number allocated from LANANA) which means that the driver will look for the first free number available starting at 254 and going downwards. For example, if you have cpint loaded first then cpint would allocate char major 254 for itself and the tape char device would get major 253 whilst the tape block device would get major 254 (assuming that no other block device had been loaded that had snaffled major 254 first). Rather than guess, look in /proc/devices after the driver is loaded and look for the allocated numbers in there. The block device minors are always single within the major. For example, /dev/btibm0 is 254:0, /dev/btibm1 is 254:1, etc. Hmm, TFM says Character device [...] The minor number for the non-rewind device is the tape device number of /proc/tapedevices multiplied with 2. The minor number for the rewind device is the non-rewind number +1. Block device [...] The device nodes have the same minor as the matching non-rewinding character device. which would imply that block device minors would be 0,2,4,... The character device minors come in pairs, and they're sequential within the device major. The rewindable member of the pair is ODD. The non-rewindable member of the pair is EVEN. That agrees with the manual. --Malcolm -- Malcolm Beattie [EMAIL PROTECTED] Linux Technical Consultant IBM EMEA Enterprise Server Group... ...from home, speaking only for myself

Re: Adding DASD to a guest, going from zipl.conf to dasdfmt w/o a reboot
Well, ok, from apples to oranges we go ... Last time, you complained about bash (or any shell for that matter) interfering with the content of the message being sent to the VM CP. OK, that's fixable from the user's end. SMSG is a totally different beast. While it indeed is a Class G command, it's also designed to communicate special messages between guests, one that the receiver is programmed to deal with and maybe even reply to. Note the difference between the two on the initiator's end: your terminal will lock up on a CP command until the response + a READY is received; but you'll get back a READY from SMSG immedately. There's a reason for this: one protocol is synchronous, and the other (SMSG) isn't. That would be my guess as to why you don't see SMSG replies, but I'll betcha its author (Neale?) could jump in here and confirm (or not) that. I don't get responses from hcp smsg at my ssh terminal, either. But if I set myself as SECUSER to the Linux guest, I can see all the responses to my SMSGs on the CMS tube as SECUSER traffic.

Re: Something akin to ISPF's skeletons?
John,
One of the most bizarre things I could ask of an MVS transplant
is to look over autoconf, but it does more or less all of the
things you want to do. It requires a skill known as writing
m4 macros, which isn't _completely_ bizarre, but it will probably
look like Greek to you on your first pass.
autoconf was designed to output all those configure scripts you
must have seen all over the place ... it builds them from a template
(what you're referring to as a 'skeleton'). You can literally build
anything from autoconf templates.

Please respond to
Linux on 390 Port
This is definately for the MVS transplants. I'm looking at doing something
akin to what ISPF does with its skeleton facility. That is, I have a file
which contains JCL. Instead of hard-coding some things, there would be
variables which would be replaced by the appropriate content when a
script
is executed. For instance, suppose I have a script similar to:
#!/bin/sh
mfid=$(id -an | tr 'a-z' 'A-Z')
acct='(A,B)'
jobclass='A'
msgclass='C'
pgmrid='John McKown'
.. do skeleton processing here
.. more processing
The skeleton would contain something like:
//{mfid}A JOB ${acct},\'${pgmrid}\',
// MSGCLASS=${msgclass},
// CLASS=${jobclass}
After processing, some output file would contain:
//JMCKOWNA JOB (A,B),'John McKown',
// MSGCLASS=C,
// CLASS=A
What I was thinking, but obviously doesn't work is:
cat EOF output.file
.skeleton
EOF
If I make the cat command as the first statement in the skeleton and the
EOF the last statement, this works as I want. For some reason, I find this
inelegant.
Where skeleton contains the above. But I can't thing of a way to source
a file within a HERE document. So far, I'm only using BASH. But this may be
a case where I'm force to something more powerful such as Perl.

What I believe I need to do in order to get my boulder sized backups without taking the linux LPAR all the way down/up is this: Change to runlevel 2, and let the system handle getting various things down through normal channels. Runlevel 2 is going to start the following, by default (not sorted by number - sorry) S02dhclient S10at S05network S10mysql S07route S10quota S08proftpd S10raw S08snmpd S11lpd S01SuSEfirewall_init S08syslog S11smbfs S01dummy S10acct S11xntpd S01random S10argus S12cron My question is this: Where does telnet get started, will it stay active through a runlevel 3-2 shift and if not how does one start it. Secondly, since I don't use the SuSE Firewall, is there a point to me having this in rc2.d? I also wont need the SMBFS or mysql started. I'm just loathe to remove things from rc2.d since they are 'stock' and would be replaced in an OS upgrade Why runlevel 2? I want everything to halt so I can run a script that will take the file systems one by one and mount them read only and initiate a dd disk copy to a matching set of spare volumes. I'm not sure that I want the system in single user mode, since our operators really don't have anythign to do with this, and I want to be able to telnet into the box if I have to dial into work to fix things. Once the dasd has been mirrored, I want to take it offline to linux, send the system back to runlevel 3 and continue on. The one problem I'm having is with a component of DB2 connect coming up. I have had to manually issue db2start from the db2inst1 ID after the system is up, so I also need to know if it's possible for a script to do an su to the db2inst1 ID and still issue a command when it's time to bring the system back to runlevel 3 any examples of unix shell scripts that do things like this I could see would be most helpful. All this for lack of a backup client that doesn't suck, since I cant play in the 3494 because nobody here trusts linux/amanda to handle it properly

Re: SuSE Start-up
If this works at all like Red Hat's sysinit, and if you need to absolutely guarantee that your script runs at the very last, you'll need to name it S99zsomething ... the execution sequence of script files in the directory is determined by the collation order of the filenames found in it. However, the first letter of each filename must be either K or S. You'll also need to add this symlink to every runlevel's rc.d/rc.n in which you want it to run. Remember that some runlevels are targets just after booting, and some of them (0 and 6, usually) are invoked at shutdown. --Jim-- James S.

Re: vi vs. ISPF
How about this little workaround? echo set showmode $HOME/.exrc Now fire up vi. Command mode is the default -- nothing shows on the status line. The status line at the bottom of the screen will tell you when you're in insert, append, or replace mode, just like the little insert indicator will come up on a 3270's status line :-) I agree with many ... this is a religious war, and you should do whatever floats your boat. Personally, I use whichever editor I have available. vi just happens to be ubiquitous enough to use on any self-respecting *nix machine (although I do have a story about one user's box I had to work on that had neither man pages nor vi -- he liked pico, and couldn't bring himself to waste the disk space ... sheesh). I never liked having to memorize keystrokes, but then again, 3270s just aren't available everywhere you go. vi wasn't *that* hard to learn after 20 years of working with ISPF/XEDIT. It just took a little getting used to, and I gotta admit, it has its strengths. One of these is not having to set EDITOR when working with CVS :-) Oh ... that One True Editor was Windows Notepad?

Re: Suse 7 kernet 2.4 Packages
Hello Ken, Warning: Im not running SuSE. 1) Yes, you've added it, but it's not useable yet. You'll then need to: a) Low level format the disk surface (see man dasdfmt) b) Partition it (see man fdasd) c) Apply a filesystem to it (I suggest you see man mke2fs, but you have other alternatives) d) Mount it to the system at the directory of your choice. You should add this device and its mount point to /etc/fstab. 2) Never run YAST in my life ... I couldn't tell you a thing about it. Welcome, and good luck --Jim-- James S.

I added new DASD today to our Suse 7 system, kernel 2.4. I edited /etc/zipl.conf and added the new DASD, and then I issued a zipl. Is this the correct way to add DASD? 2.) One of our testers wants the kernel source, so I perfomed the following steps: - Yast - Package management - Load Configuration - Change or create configuration - selected zq Source packages - selected kernel-source_spm When I selected the item, the amount of free space went from 95.7mb to 71.8m - Start installation It then downloaded the package and showed Installation complete When I looked at the amount of free space on the one disk, it had returned to 95.7. It seems that the source has not been installed. I have 2 disks, one with 95.7mb free, and the second with 2.11gb. I also tried a smaller source that even when expanded would have fit on the first drive, but I get the sane result. Does anyone know what step I am missing? Also, once I finally do get the source, what directory will it be in? Thanks, Ken Vance Amadeus
Re: ZIPL - confused and dazed
James, Partition checks are a normal part of the system's boot cycle - it lists all the partitions it sees on your system. It looks like it sees no partitions on your dasdb device, though, which is a cause for alarm, unless the IPL just stopped before it could list /dev/dasdb1. I'd be grasping at straws to guess at what this might have to do with your IPL halting in mid-stream. I'm not running SuSE. I have to wonder what happened to the partition table on dasdb, though, provided that the IPL just didn't stop there by chance. Is it possible you ran zipl against the device (dasdb) and not against a partition on that device (dasdb1)? Maybe that might explain it? dasdb1 is supposed to be your root disk ... whenever I've been in situations where the kernel couldn't mount the root device for any reason, it's complained very clearly and loudly about that very fact. This IPL freeze is odd. I don't know of any layout requirements (CDL/LDL) on the swap DASD. --Jim-- James S.

I used 0d1d I believe as /tmp, 0d1a as /var, 0d19 as /opt and 0d1b as /usr I think - not that this is probably relevant. Of course, yast re-arranges things so that swap is always dasda.

Re: Regina/rexx SOCKET
Has anyone used Object Rexx? What do you think of it compared to Regina? Yeah, I have; but I've not played a lot with Regina ... its dialect seems a tad foreign to me; but that's only because of my IBM upbringing. I'm not a good one to judge the relative usability and friendliness of each. Object Rexx is a direct inheritor of Mike Cowlishaw's original REXX effort as implemented on VM. It supports everything that the original REXX did in the same way, and adds the ability to create C++-like classes with embedded methods. There are some new keywords (DO OVER, for example) that work with classes which turn out to be huge noise-level code-savers and quite convenient to work with once you get used to it. There are also some default classes to support I/O streams, for example, that are also very, very nice. It *does* support all of the old (non-OO) syntax semantics, at least as far as I could tell -- in many cases you have the choice of doing things in the old procedural syntax or the new OO way. Veteran REXX coders won't be disappointed. If it were up to me, I'd spread Object Rexx (as opposed to vanilla Rexx) over the entire IBM OS set -- there aren't versions available for TSO or CMS. It's pretty nice. If you've got the right Linux machine (there are no s390x/ELF64 binaries available), you can download it and try it for free (I believe). I strongly suggest doing so if you're curious it comes with PDF documentation. I use it on all of my Linux ix86 machines ... I'd love to use it on my zLinux ThinkBlue64 machine; but there are no s390x binaries available for it. Am still looking fo replace ThinkBlue with a slightly more modern s390x based distribution that handles ELF32 modules in compatibility mode. Object Rexx is the primary reason. --Jim-- James S.
