After that, the exec could then delete the existing file and rename the new one to the old name if needed.

How do we insert in the beginning? I am using REXX for this program. There is no direct way to insert data into a sequential data set, neither at the beginning nor inbetween. You need to re-write the dataset with all the new and current records in the desired sequence. If the dataset is not too big, you can read it into storage using EXECIO then write everything back out with multiple EXEXIOs. You can also use one of various ways to concatenate the input datasets and copy them into a new output dataset. -- Peter Hunkeler Credit Suisse -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: question about Oracle on the mainframe
The reason I heard why Oracle 10g was the last release supported on z/OS was that IBM did not have any plans to update their clandestine Media Manager to 64-bit addressing.

We just recently upgraded to v10.2.0.3.0 and are running it under z/OS v1.9. Oracle v10.2 is the terminal release for z/OS and premier support for it ends in July 2012, although extended support after that indefinitely for a price. If you ever want to go to v11, it can't be done on the mainframe unless you run it, as others have mentioned, under a z/linux-z/VM partition (which I'm hoping we'll get to try out sometime).

Re: question about Oracle on the mainframe
Oracle on the mainframe. Here are a few highlights done here 1. Have Oracle DB on z/OS but it is functionally stablized in the 31 bit mode. 2. Have z/VM LPAR Virtual Linux systems: a. Oracle DB in 64 bit mode which use Websphere Application Server running on another Virtual Linux. b. Oracle DB in 64 bit mode and Oracle Application Server c. DB2 in 64 bit mode with Websphere Application Server 3. Another variation has Oracle DB in 64 bit mode in a Virtual Linux Server on the z/VM LPAR with the application running in Websphere in a z/OS Parallel Sysplex. 4. Consider Oracle licenses are the same for a 2-Core Server (or laptop) equates to 1-IFL (0.50 Intel Core = 1-IFL) on z800/890/900/990/z9BC/z9EC/z10. If you are talking about AIX/UNIX, then it is 0.75 Core = 1-IFL. You should get onto a z/VM talklist where they have adopted zLinux under z/VM with a passion. You can contact me offlist for some material I have written over the last few years concerning what you would need and the choices for support, etc. QUITE reasonable in cost when you factor in what an IFL can do with all those Virtual Penguins running things like Oracle, DB2, Websphere, Firewalls (free), Routers (free) , z/VM VLANs (free), Switches (free) and miles and miles of FAST free virtual cabling not to mention all those virtual twist-ties to organize things. jim -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

TSSO Error TSSA305E
I'm trying to utilize the TSSO AOF table to kick off a TSSO clist when we get the IKT005I TCAS IS INITIALIZED during TSO initialization. The AOF table entry looks something like this: TABENTRY MSG=IKT005I,ACTION=OSCMD,ECHO=YES,TEXT='#TSOUP' TSSO recognizes the message but instead of executing the clist it issues the message TSSA305E TSSO COMMANDS MAY NOT BE ISSUED FROM THIS ENVIRONMENT. I thought this might have something to do with the console changes in z/OS 1.9 so I tried it on our old z/OS 1.7 rescue system with the same results. I was able to get around the problem by branching around a test for the contents of SSCMCNID in module TSSOSS10: CLC SSCMCNID,=F'0' BNE STAT4 I'm not familiar with the rules concerning when SSCMCNID should be non-zero so I don't know if this is a legitimate fix in TSSOSS10 or if I'm doing something else wrong in setting up TSSO.

Re: IBM PR: System z Announcement Webcast on October 21, 2008
Looks nice. Right now, from my perspective, the war is between the z and Intel based servers. A less expensive z server might be nice. One problem I've noticed is the lower cost of entry for Intel. Granted, once we are comparing equally sized environments, the z come in well. But, too often, the comparison is one z versus one Intel server. The z loses in this case. Of course, this still does not address the horrendous cost of software for the z, especially z/OS. Comparing a z penguin farm (Linux) to an Intel penguin farm, the z would almost always win. The only case where I can think of Intel beating z would be in a compute intensive application. Also, z/VM still makes VMWare look sick and immature. -- John -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Another logical place to look is the description of the LOADxx and IEASYMxx members, where the IEASYSxx members are specified, or in the system commands manual, where the SYSP reply at IPL time is documented.

Five sentences later, it reads, Because IEASYS00 is read automatically When I read that it prompts me to look further for more information. You can do one of the following to specify a parameter list other than IEASYS00 for an IPL: (key phrase - other than IEASYS00) Right. If you don't specify another, the system reads *only* IEASYS00. Specify one or more suffixes of alternate IEASYSxx members You skipped one: Have the operator specify the suffix of an alternate IEASYSxx member by replying SYSP=xx in response to the SPECIFY SYSTEM PARAMETERS message (see SYSP in topic 49.1 for more information). If you had followed the link to topic 49.1, you would see: Specifies one or more alternate system parameter lists (IEASYSxx) that are to be read by NIP in addition to IEASYS00. And the next sentence after the one you quoted reads, For further information about IEASYSxx parmlib members and system initialization, see Step 2. Determine where to specify system parameters in topic 2.3.2. If you followed that link, you would see, IEASYS00 is the default member; you can specify additional IEASYSxx members as needed. You would also see Table 7, which says clearly that no matter where you specify IEASYSxx members, IEASYS00 is always used. (alternate means - in place of - not in addition to) Not necessarily. Here it refers to an alternate place to specify system parameters, which is correct. It does not mean an alternate place What part of unless you read all of it in my OP wasn't clear? :-) It was clear.

Observations and Questions About Our Platform
Something hit me today after I called the IBM Support Center today. If I remember correctly, the first question is: is this a Lenova product or something else. Then they give a whole bunch of options, none of which is their bread and butter product - z/OS. Finally, you reply all other requests, or some such thing. Why does IBM have their first question for Lenova, when they don't even own the PC line anymore. I'm not quite sure what IBM's relationship is with Lenova. I gather they still market their products. Also, why not a choice on the 1st or 2nd menu for z/OS software, from what I understand still one of IBM's biggest moneymakers. This just struck me as odd considering the recent thread about Oracle and SAP software being stabilized for the mainframe, and not having any new releases of them. What is happening? When two major software players indicate they are getting out of the mainframe, this can't be good for our livelyhoods. In the last 2 and 1/2 years when I've been unemployed about half the time, I often thought about looking for some other type of employment. Then, I think of having only half or less the income I can make as a sysprog, so I keep looking for sysprog jobs. Fortuneatly, my current job is very interesting, and there is a good chance I'll get hired permanently. Then I won't have to worry about the employment thing anymore. Also, if IBM is giving up on the mainframe, I'm close enough to retirement that it won't matter. I'm sure it will carry on for 5 to 10 years or more even if IBM gives up on it. I really don't think IBM is giving up on the mainframe, but I wonder. I've gone on too long already.

Re: How to insert records using EXECIO
Depending on the number of records in the input file, EXECIO may not be the most efficient way to do this. But you could create a new file with the new lines in it and then use something like IEBGENER later in the REXX to mod the data from the original file into the new file. The reason to do it this way is to protect your original file from being corrupted should there be a failure of some type (x37, 0Cx, etc). Mod will normally add lines to the end of a file not to a beginning of a file.

However, that said, many companies may regard the current Intel as good enough. And today good enough is superior to best to most managers. As an example. We were looking at moving our z/OS workload to an Intel server farm (starting with 4 systems as I vaguely recall). I asked about what happened if one of the 8 CPUs in a server died. The response was that Windows would recover (not crash), but that the current work running on that CPU would die and need to be restarted. I compared that to when a CP on our z890 died. Another CP took over the in-flight work with absolutely NO impact to anything. In fact, if EREP and the HMC had not told us that a CP had died, we never would have known. The same when one of our OSAs died. The other OSA transparently took over. Shocked the elided out of the open people that we didn't lose any connectivity or even any IP sessions.

Re: Shared PARMLIB placement
I would make a stronger case for *not* putting *anything* but couple data sets on a designated volume. Even apparently benign files can cause a problem. For example, your PARMLIB runs out of space and needs to be compressed. You don't want to run IEBCOPY against that volume. Even if the PARMLIB is healthy, you surely want a periodic backup of it. Backing up the entire volume risks holding it long enough for XCF to drop the couple data set(s) as unusable. Backing up only the PARMLIB may involve a special process unlike other backup/restore processes. In other words, more chance of error. In short, find a safer spot. . .

If the access is low and nothing would ever reserve the volume by accessing the PARMLIB, then it shouldn't be a problem. But isn't there a better place (like IODF volume that is also shared)?

Audible alarms on SMCS consoles?
It occurred to me today that I've never heard a 3270 audible alarm on any TN3270 session in my shop. I went looking around and discovered that Zephyr Passport (the prevalent TN3270 client here) supports bell and custom alarm WAVfiles. It isn't obvious whether x3270 supports audible alarms. I'm not getting audibles out of the HMC x3270 instance connected via OSA Express2, or my own x3270 client talking to the z/OS TN3270 server. Neither have I ever heard a peep from ANY of the TN3270 emulators. Suddenly I have a need for this, as the last green screen is heading for the boneyard and the operators relying on SMCS consoles need the beeps to keep them awake. So: do TN3270 SMCS consoles support audible alarm? If so then where should I look to enable it? Is this a forgotten VTAM features or modetab thing that languishes in obscurity? -- David Andrews A.

We do the basically the same for our general test. However, we have some specialized systems, like our Tandem that runs wire transfer, that we test more often. It depends on several things 1. How much do you want to spend in money and people hours (which translates to money). 2. Do you have your own DR site or are you buying DR support from a company like SunGard. If you're buying your DR support that translates to more money because you'll be renting their facility while you do your test. Also, you'll have to coordinate with them as to the days/times you can test. 3. Do you want to do a planned or unplanned test. By a planned test I mean one where everyone knows when your going to test and what your going to test ahead of time. An unplanned test would be one where upper management declares that a disaster has just occurred and you need to go to your DR site. They might also declare certain key personnel (like your lead MVS sysprog) as victims of the disaster which means they won't be able to take part in the test. That's to see if you have well written procedures in place that an intelligent, but untrained, person can follow. The unplanned test is more revealing of how well you're prepared, but it is also harder and more expensive to accomplish.

Then because of natural disaster considerations ... the load-balancing was extended to a replicated 2nd HONE datacenter in Dallas and then a replicated 3rd HONE datacenter in Boulder (there were approaching 40k defined userid on the US HONE system complex ... and mainframe orders couldn't even be submitted w/o first having been processed by HONE). Note that while the HONE support provided load balancing across the complex and various other single-system-image transparency ... it didn't support process (virtual machine) migration between different machines in loosely-coupled complex. In the very early 80s, SJR started a 4341 vm-based cluster project using 3088/trotter (this was before moving up the hill to almaden). One of the big problems before being released as a product, they had to migrate the implementation to standard SNA protocol. This had disastrous effects on the cluster operation efficiency. For instance, the original cluster syncronization process that took very small subsecond elapsed time, increased two orders of magnitude when migrated to standard SNA protocol (over 30 seconds elapsed time). -- 40+yrs virtualization experience (since Jan68), online at home since Mar70 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
