Re: 21st Century Migrates Mainframe with Clerity
Hi Tom, if you click on the link it shows the following: Up to 8 physical cores or 16 logical cores through Hyper-threading The old Hyperthreading implementation was not really two logical cores per physical core (some things were shared such as the floating point unit), but Intel changed the implementation when AMD came up with the 6-12 physical cores, such that now Intel Hyperthreading logical core is performing much better and AMD comes not even close in termes of performance. So if you calculate with an Hyperthreading enabled 6 core, you get 4,5 instructions per clock cycle per core.

Re: What am I missing on XPLINK(OSCALL(N)) ?
You cannot call 24bit modules with XPLINK(ON), XPLINK forces ALL31(ON), it is
documented here:
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CEEA31A0/1.2.4.2?SHELF=CEE2BKA0DT=20090608042151
Here is an except from the z/OS 1.11 Language Environment Programming Reference:
1.2.4.2 Usage notes
Restrictions: You must specify ALL31(OFF) if your COBOL applications
contain one of the following programs:
VS COBOL II NORES
OS/VS COBOL (non-CICS)
If the Language Environment environment was initialized using
ILBOSTP0
PL/I considerations-- For PL/I MTF applications, Language Environment
provides AMODE switching. Therefore, the first routine of a task can
be in AMODE 24.
Fortran considerations--Use ALL31(ON) if all of the compile units in
the enclave have been compiled with VS FORTRAN Version 1 or Version 2
and there are no requirements for 24-bit addressing mode. Otherwise, use
ALL31(OFF).
XPLINK considerations--When an application is running in an XPLINK
environment (that is, either the XPLINK(ON) run-time option was
specified, or the initial program contained at least one XPLINK compiled
part), the ALL31 run-time option is forced to ON. No AMODE 24 routines
are allowed in an enclave that uses XPLINK. No message is issued to
indicate this action. If a Language Environment run-time options report
is generated using the RPTOPTS run-time option, the ALL31 option is
reported as Override under the LAST WHERE SET column.
Guideline: ALL31 should have the same setting for all enclaves in a
process. Language Environment does not support the invocation of a
nested enclave requiring ALL31(OFF) from an enclave running with
ALL31(ON) in non-CICS environments.
Denis.

I've got some C++ code. The C++ code calls several functions written in
assembler. This all works non-XPLINK. I compile it with XPL(OSCALL(N)). I
bind into a PDSE. I run it z/OS batch. The C++ code takes off and runs. I
can see that it survives several C++ method calls. The first call to one of
the assembler functions it falls on its face somewhere after leaving the C++
code and before returning. Storage has been overlaid badly enough that the
save area trace and so forth is pretty much junk. I have desk-checked the
assembler function - it's only 50 lines including lots of comments - and as
I said, it works non-XPLINK. It makes no calls although it does do a STORAGE
OBTAIN,LOC=24
Am I doing things generally correctly? What should I be looking for?
The assembler routine is defined in the C++ code as
extern OS {
myStruct *GETG24();
}
It begins GETG24 EDCPRLG DSALEN=CDSALEN,BASEREG=R12 and ends with EDCEPIL
, and once again, it works non-XPLINK.

Another thing could be to make the HFS directory the default when logging in with a FTP client. But that does not reject ZZZ. datasets to be created. Its just that you have to issue a cd commend cd 'ZZZ.' first in order to be able to create such a dataset.

Re: Java Batch und JCL (DSN Disposition)
I don't understand.The scheduling software and the operations people look at the return code and respond. But instead of poring through a dump, the displays tell them exactly what happened, making it easier and quicker to find out what they should do as a result of the failure. Thats the theory. How would you do that at 1000 tx/sec? And how would that work with the poor programming that sometimes comes from the cheaper programmers that are initially hired these days? Examples from experience: 10 return codes for 25 error reasons. Untested software paths. Software not regression tested, but put into production. A return code not being documented, because the documentation is out of date or not updated. Why default to the standard ABEND when I can give specific information and ABEND in a controlled manner? If the specific information is provided. Thats only the case with expected (caught) errors, not with unexpected errors. I would say, a dump cannot lie. A return code could. What if the return code comes from generated code and you don't have the documentation of those APIs handy as operator? And what do you do with the return code in that case? When failure *does* matter, I like to give the best information I can, and I like to make the failure as controlled as I can.

You turn on autocommit for JDBC clients, because you don't want deadlocks or long database locks. You turn it off and leave control to the programmers, you earn long locks, deadlocks and slow processing/low parallelism. Other example: I believe the advantage of abend and rollback is, that the rollback takes place immediatly after abend. So the database locking time is short. It is unpredictable how long the time between error and rollback is if you leave control to the programmer. A program might do other things before issuing rollback. Keep a 1000tx/sec system in the back of your mind. It might (based on the database access requirements - locking) immediatly stall due to deadlocks as soon as a crucial database record is locked longer than 100ms.

Re: Java question
Hi Peter, sorry for the delay, but I have been traveling. For all the statements I did, one of the thoughts behind it was, that HPJ compiled code does not run in a JVM as HPJ was implemented years ago. So the whole JVM runtime was replaced by PDS members that are load modules just like any other languages load module. So with HPJ there was no JVM during execution. According to your reply: 1. Thats correct, however as I stated, you loose all the standard stuff that comes with a JVM and you loose the capability to have a runtime (JVM) that behaves similar and can be tuned and parameterized similar to other platforms. You are right, that HLL languages can use memory management too, but there must be some overhead in doing that or switching it on, so that was basically what I was refering too. The compiled code must implement functions etc. to do the memory managment, because it does not use the JVM and its garbage collection mechanisms anymore. Or as a prereq, the whole compiling stuff would not make sense, if you still run in a JVM, because of the options that todays JVMs provide. 2. I recall from the implementation of the High Performance Java Compiler, that the compiled application is a statically linked huge load module (think of a 50MB classpath). In addition, if you have many Java classes with a Java main Method, which is executable as a starting point, each of these Java Main Programms will be its own statically linked huge module and also has all classes from the classpath compiled into it. So HPJ produced huge load modules and was very inflexible, not only in terms of reusing compiled code. If it were enhanced to support dynamic calls, you would have a need to have a 1:1 relationship between Java class and load module, thus a lot of members in the load PDS. 3. Because of the fact, that you cannot really influence the behaviour of the JIT compiler, we only test with all optimizations switched on, that works pretty well. Once in while there are applications which do not work with the highest JVM Optimization level and there are switches to force a certain optimization level or to restrict optimization up to a specific level. Yes we trust the compiler, however if something goes wrong, you still get an exception, traces, etc., which you do not get with the compiled version, because the JIT compiler is somehow part of the whole JVM construct and in the compiled version you do not have the JVM anymore. Basically when there are tuning advices for WebSphere z/OS or for a distributed JDK, most of the recommendations also apply to the JVM on z/OS, so getting rid of the JVM in favour of just having compiled code would also make the execution environment on z/OS incompatible to all other Java environments in terms of behaviour, problem determination, tuning and customization. Nevertheless I admit, that there would be some benefit, if the JVM on z/OS could save JIT compiled code into datasets or HFS image, once the compiled code reached a higher level of optimization. This could be enhanced to load a JIT image during JVM startup which has the most used classes already compiled. Or when classes are used among multiple JVMs, in addition to the shared classloader cache having a shared JIT cache would likely have its benefits. But reading the documentation, these are not there nor planned. 4. I recall that transmeta had a processor, which loaded a Millicode on startup, so basically a RISC processor with that capability could easily load the newest JRE version on every IPL. 5. Yes it could, but it never did, by the time the HPJ was there, we had no zAAP. And HPJ code never run on a zAAP. Hope that helps.

I basically concur with you. I'd like to reply to a few arguments, though: 1. Today's JVMs offer the option to have the byte code compiled on the fly when certain conditions are met. So, these JVMs already have the capability to run machine code instead of byte code. This is the runtime environment you'd need to run Java code that has been compiled at the will of the programmer instead of at the will of the JVM. All you need is an option to tell the JVM where to find and/or how to recognize pre-compiled java class files. No need for a new runtime environment, no need for application programmers to care any more about memory management as they need to care about with today's Java environment. You still instantiate a JVM and tell it which Java class file to run. BTW, programmer's don't need to care about memory management in other HLL languages, do they? It's the HLL's runtime that manages this. 2. Why do you think that compiled Java class code needs to fill PDSs? The JVM does *not* create PDS members when the JIT
Re: Java question
I believe one of the reasons is, that you need a JVM as runtime in order to get 100% Java certified. In addition your runtime components would have to implement the standard Java configuration switches, such as -classpath -cp or memory settings such as -mx in order to be standard. The runtime would have to produce the standard traces, support will likely ask you for a verbose or verbose:gc trace or runhprof file, if an application does not perform or has memory leaks, how would you create that with compiled code? Java is known as a memory managed runtime, which means that the application programmer does not care about memory and the runtime will have to manage it (that is the reason for garbage collection in Java), so running a poorly programmed Java application as compiled code, will give the runtime environment a hard time, since it would have to log all the getmains and do the freemains, since the Java application is not designed to do that (Although good programming practice would be to reuse as much objects as possible). So there are a couple of things which would add overhead to the native java code runtime, so that the difference to running the JVM would be rather small. I just tested ILOG JRULES ISV application (which allows to create business rules on a GUI and generate Java class implementations of the created rules) and the jexcel API (open source project which allows you to create Excel files from Java - we used a sample to create Excel Files out of IMS databases) nativly in z/OS by just putting the jar files to an HFS and adding it to the IMS Java regions classpath, for ILOG these are about 50MB of .jar files. Given that the compile will not fail it would create a huge PDS and a huge amount of load modules, so I am not sure if in the end you would have much benefit of compiled code. Basically you loose a lot of flexibility and you would have to test an application twice - once in your development environment and once as compiled code. There is also cost associated with that, not only MLC based on MSUs. Since JDK 1.5 the JVMs have a codecache, which caches the native code which was generated by the Just in Time compiler (JIT) out of static methods. So if a JVM lives for 10 days, the benefit of compiled code would be that the first 10 calls would probably be faster with compiled code (given that all the required load modules are preloaded and you don't need IOs. For the JDKs from 1.5. you have the shared classloader cache (and you can have multiple of it for different application workloads, e.g. IMS Java regions 1-4 are for App A and use the same shared classloader cache and IMS Java regions 5-10 are for App B and use a different shared classloader cache - similar to having different Proclib member with lists of modules to be preloaded) which saves IOs once the classes are loaded. In addition the newer JVMs are able to optimize the native code as needed, so when a java method is heavily used, the JVM will try harder to optimize the created native code. I always wondered why the concept of having a pure Java processor or co-processor (a processor that implements the Java Byte code nativly or in millicode) never arrived on the market, although everybody would expect that to be more powerful than executing JVMs on general purpose processors. But having a native Java processor or compiled code alone will not address all the associated stuff that comes with an application life cycle and not to forget the operational aspects of running an application. It rather seams to be more practical and cheaper to have loads of processor cores (look at SUNs last Sparc processors) which are capable to run a huge amount of JVM threads in parallel with one thread associated with one processor core . Another thing that comes into mind, think of the Java releases and versions coming out on a monthly base, how men power consuming it would be to keep your compiler in sync with the current Java versions. And last but not least, there is a big chance that the pure Java stuff can be offloaded to zAAPs. So given some of the facts above, I cannot really understand what the benefit of compiling shall be. ;-) Denis. -Original Message- From: Hunkeler Peter (KIUP 4) peter.hunke...@credit-suisse.com To: IBM-MAIN@bama.ua.edu Sent: Thu, Aug 6, 2009 8:39 am Subject: Re: Java question High Performance Java (HPJ) [snip] It was discontinued, for a number of reasons, when Java 1.2 was released.

Re: Authenticate with RACF from Web App
Hi, the easiest approach I have ever seen works like this: The web server on distributed redirects (easy to implement in distributed http.conf) to the HTTP Server on z/OS (this is the free one, not WebSphere Application Server). I recall the ITSO wrote a simple CGI program/Exit, which allows to autenticate with RACF and even change the RACF password, if it is expired. On successful authentication the z/OS HTTP Server can redirect back to the distributed web server and it can proceed working with the request. Nevertheless there are some additonal considerations, e.g. what data to send with the redirect (e.g. generated 128 byte hex token send to z/OS and back and of course by using SSL/HTTPS) in order to make sure that this authentication cannot be bypassed. But this is not rocket sience and the CGI programs for HTTP Server on z/OS can be REXX, so any additional logic would be easy to implement.

Re: Batch Process Calling a Web Service
Hi Bill, tell your Java programmers to write an Java Client for the Web Service. Then create a COBOL wrapper for that Java program with Enterprise COBOL. Call that COBOL as subroutine from your Batch COBOL. Enterprise COBOL will create the JVM in the same address space and reuse it. An example on how to call a Java class from Enterprise COBOL can be found here: http://www.ims-society.org/board/viewtopic.php?t=79 The sample is how to do it for an IMS online program. However, its a compiler function so you can do that in any z/OS address space! This way you do not have to deal with 404. In addition COBOL can also get control when there are Java Exceptions and act accordingly (e.g. rerun the request).

Re: COBOL and dynamic allocation (my two cents)
I personally think its also a matter of setting standards. If there is no standard like always code destination in JCL or like always code destination in parameter dataset or there is no force to always use the parameter dataset both approaches will never be successful.

Re: Comparing Mainframe and Windows Server CICS Transactions per kWh
z/10 Announcement probably is based on a specific usage pattern, that most of PC processors are idle. The microsoft study misses some points. I can hardly believe that the power consumption is equal with all different workloads. It is not clear if the mainframe also had just 2x73GB harddrives and just one OSA card, just one FICON card, etc. I think it is invalid to compare a power consumption of a system that runs 984 transactions per second with a system that runs 354 transactions per second (see page 9), because if the throughput is not the same, this is similar to claiming that a car running 200km/h needs more gas than a car with 80km/h. Or looking at the Java throughput that seams to be better on a PC is like claiming that a truck cannot run with 200km/h. In addition Microsoft used NETCOBOL Compiler on the mainframe and I have no clue how the resulting machine code compares to other mainframe compilers. Based on the paper its not even clear if unoptimized COBOL was compared to optimized .NET code?!

Re: TN3270 for iPhone
My point is, that Ebay sent me a secure id card which can be used instead of a fixed password. Userid password is not state of the art security these days. State of the art banks use smartcards in combination with userid and password in addition to indexed TANs for each transaction. When I wrote diploma thesis the suggested rule was posess something (smartcard, key, certificate) and know something (password, if not written down) provides good security. By the way, most web shops (not sure about Ebay) do not revoke userids after 3 wrong passwords. Web Shops usually have a password question to get a new password, which is not implemented in RACF. So one might say, a missing function will keep RACF administrators busy, although additional tooling can provide a similar way to resume RACF Userids. We used to have a VM application that could be used to resume a RACF user without any admin intervention, this has been expanded to a web interface about 5 years ago. A z/OS exposed to the web should also make sure that nobody can guess Started Task Userids, when they are revoked after 3 false passwords that has nice impacts to your z/OS (Happened to me once due to a user using the first userid that he found in syslog for some testing).

In case of XML use the Cobol XML parser to extract the data. Roland I got a question asking for recommendations on how to write a COBOL application (on z/OS) to act as an HTTP client. That is, the COBOL program makes an outbound HTTP request, provides some input data, and receives some data back. The data format is arbitrary -- could be XML, could be just simple strings. Further assumptions: there's only Enterprise COBOL (compiler) and base z/OS (including any standard and no charge features). Also, there are significant bonus points awarded for high service quality attributes (RAS, security, performance, etc.) It broke! is not adequate diagnostic information if something fails, like the network or authentication to the remote HTTP server. :-) The same method could be used with Enterprise PL/I programs without any material differences.

Re: XPLINK
Hi,
I am not 100% sure, but I recall that coding //STEP1
PGM=JAVACALL,PARM='XPLINK(ON)' once worked for me.
I prefer a CEEUOPT Module linked with the application, similar like the SYSIN
below as input to assembler:
//SYSIN??? DD *
TITLE 'CEEUOPT'
CEEUOPT? CSECT
CEEUOPT? AMODE ANY
CEEUOPT? RMODE ANY
CEEXOPT XPLINK=(ON),? X
?? POSIX=(ON), X
?? ENVAR=('_CEE_ENVFILE=/u/gaebler/hello/ENV')
END
//*
The file /u/gaebler/hello/ENV can then contain USS Variables, but there are
also DD Statements to achieve this:
LIBPATH=/usr/lpp/java/J5.0/bin
PATH=/usr/lpp/java/J5.0/bin
...
Hope that helps.
Denis.

Subject: XPLINK
Hi List,
We are Z/OS 1.7 with Enterprise cobol 3.4 and SDK 1.4
I'm trying to run an OO Cobol program which invokes a Java method
and I'm having problems with the LE runtime option XPLINK
The compilation and linkage work find.
I'm trying to run the program using the BPXBATCH utility
with PGM myprog and STDENV DD which contains
_CEE_RUNOPTS=XPLINK(ON)
Even so I get the following error code:
CEE3555S A call was made from a NOXPLINK-compiled application to an
XPLINK-compiled exported function in DLL libjvm.so
and the XPLINK(ON) runtime option was not specified.
From entry point GetJVMPtr at compile unit offset +00B8 at entry offset
+00B8 at address 3E8AB618.
Any Ideas?
thanks
Magen

Important: If the certificates are generated using another userid than IMS
Connect is running under, you will get RC 202 errors, when trying to connect to
the key database.
You can then do an ASCII download (e.g. FTP) and create a keystore on the
client. This can be done with the keytool, which is part of every Java SDK.
cd 'USERID.'
ascii
get CERTAUTH.CERT
This is how to create a keystore, which can be used with Java:
keytool -import -trustcacerts -noprompt -keystore IMSKeyStore -file
CERTAUTH.CERT -alias CA

Subject: Import Connect:Direct self-signed certificate into RACF?
Hi folks
Has anyone managed to successfully import into RACF a self-signed server
certificate generated by Sterling Commerce's Windows-based Certificate
Wizard?
I've been sent one by one of our customers; they use it on their Windows-based
C:D server, apparently quite successfully on their other C:D sessions from that
server. However I can't import the certificate into RACF as a Certificate
Signing Authority (CERTAUTH) as it issues message:
IRRD126I The certificate contains either a key usage or basic constraint
extension indicating that it may not be used as a Certificate Authority
certificate. The certificate is not added.
This seems fairly reasonable since the attributes of the certificate only
specify HANDSHAKE and DATAENCRYPT (not CERTAUTH), however, this is the standard
for a self-signed server certificate coming out of the Certificate Wizard - in
fact you can neither add nor remove attributes in this case.
I've tried importing it as a personal certificate for our C:D server, and it
accepts that. I've tried putting it in the keyring as USAGE(PERSONAL), and
USAGE(CERTAUTH) but either way C:D fails to negotiate the session, instead
issuing message:
CSPA202E SSL handshake failure, reason=GSK_ERR_SELF_SIGNED
I've had a call open for some time now with Sterling's support and although
they're being very attentive and helpful, we're not managing to fix this, and
the suggestion now is that we need to find out why RACF is not accepting the
certificate, since Windows seems quite happy to do so.
Hopefully someone out there has done this (Windows C:D - z/OS C:D)
successfully and can tell me where I'm going wrong?
Cheers
Brian

Re: Can a pdf document be create using COBOL?
Another Idea, there is a PHP (programmig language just like ASP, Perl, etc.) port for z/OS running under Apache for z/OS. PHP has PDF routines. I don't know if PHP (running under z/OS Unix) can be called out of COBOL. Nevertheless PHP is open source, so there must be open source libraries with PDF creation functionality.

Hi Jim, I never tried it with a version earlier than V3R3, so that was the reason for saying so.

Re: setting LE runtime options programatically.
Hi,
I had the same problem. This could be easily solved, by using a CEEUOPT
Module. But that means that the LE Runtime Options that should be used by the
module, have to be defined as being overridable by an CEEUOPT module. An
example is appended. In addition, this scenario is supported under IMS too, but
it is not required to run in anll IMS Java Region. Could be a normal COBOL,
PL/I program, IMS region requires more working storage and JVM can be reused
while being scheduled and looping reaching sub-second response time and zAAP
can be utilized.
If anyone is interested in a presentation covering this topic, drop me an
email and I'll send you a PDF document. Its about the IMS implementation, but
the Java Sample code used has nothing to do with IMS, you could easily leave
the IMS specifics out (In fact a simple caller COBOL transaction) and it still
does work. In fact, the sample is designed to be called not only from COBOL
also Assembler, PL/I and other languages could be Java caller.
Create a CEE Sample Member:
//HLASM EXEC PGM=ASMA90,PARM='LINECOUNT(0)'
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD UNIT=SYSDA,SPACE=(CYL,(1,1))

RACF people don't like to grant generic READ permission to all users. Is there any other solution? Could something like that be used to only allow that specific program access to TCP/IP?
