Re: JES2 vs. JES3
Hi, I think the question Which is better JES2 or JES3? is one for the bigots, and is akin to Which is better z/OS, z/VM or z/VSE? Many of the more senior members of the list will know that the two Job Entry Systems existed prior to MVS but were developed independently for different purposes. JES2 being developed from the Houston Automatic Spooling System (HASP), and JES3 was begat from ASP. As I understood it at the time HASP was classified as a Field Developed Product being created by IBM employees outside of the product cycle, whereas ASP was a bona fide development. (1969 was a long time ago so I now have Virtual Memory, in that I remember virtually everything.) One of the design constraints for ASP was to assist Attached Processor Support and aid scientific calculations which were CPU intensive. It therefore found favour in those environments. The biggest benefit of HASP that the installation I was at; was better use of printers without having to dedicated devices, as previously, or spool prints to tape for subsequent printing. All of these predated MAS and NJE. In terms of IBM preference, it is always difficult to be certain. On the one hand IBM did seem to adopt JES2, but shipped both arguably for compatibility reasons I guess. In the 1980s I did get involved with a small, 4381 site, which had been talked into purchasing JES3 even though it was unlikely that they would benefit from many of its features. (This was at the time there was a drive to move installations from VSE to MVS.) The real issue these days I think is, Is there a need for both JES2 and JES3? To what extent if any does SysPlex align the products such that IBM could concentrate development on only one? In the meantime it is horses for courses, although I doubt that anybody will convert from one to the other, as it is not necessarily a trivial exercise.

Re: JES2 vs. JES3
I am sure there will be some opinions on this. But the basic functions of JES2 and JES3 are different. I have only used JES2 and know very little of JES3. So I am a little biased. JES3 has resource functions where JES2 does not. In JES3, as I understand it, a job cannot get into the system unless all allocations are met. However, you can submit a job to JES2 and it could begin to run without all allocations (dasd, tape, etc.) being available. To handle that problem in JES2 you have add-on products like ThruPut Manager, DTS Software SCC, ACS, and so on. So to me the bottom line is more like: JES2 comes with the operating system, but how many more products do you need to add-on before it behaves (okay I will say it) like JES3? I like JES2 because it is simpler in concept than JES3. However, both products have their pros and cons. I am not sure that this can be a apples to apples type of choice. They are both apples, but do you like sweet ones or tart? Do you like Washington or Delicious? Do you like Red or Green? I think it all comes down to what you have worked on and how you have adapted to using it. Both are good systems and do their jobs very well.

I am not understanding the full intent of this application you are creating. Are these jobs the user submitted but different names? You can limit user view through the SDSF or SAF security functions so they only see their jobs. To answer your basic question - yes you can do this. However, there needs to be more of an application definition to determine what is really wanted. It almost sounds like you are going to write a pre filter to SDSF. I would not want to have to support that since there are facilities available in the z/OS system with SDSF and SAF to provide a cleaner process. So, if I underdstand 1) Provide a display screen for a user to select a jobname.How is the jobname obtained? What provides the list? 2) Once the jobname is provided issue the SDSF command with that jobname as the prefix. What functions are to be provided once in SDSF? Is normal SAF or SDSF control in place at this point? 3) Will you be using an ISPF Panel for the job selection? How are you controlling the data? Is this being fed by another process? 4) Any thing else???

I would check out the entire thread to see what they came up with. Note:
This was in the TSO REXX newsgroup. If you are at z/OS V1.9 or above, then
the SDSF REXX interface would probably make it easier. I am not sure what
ISRTSO is in this example.

If Tr_parm '' then
do;trace_on=1;Tr_parm='TRACE 'Tr_parm;interpret Tr_parm;end
else trace_on = 0
commands = SDSF da;pre d901*;sort jobname
Address 'ISPEXEC'
'DISPLAY PANEL (ISRTSO) COMMAND('commands') RETBUFFR('bufname')
RETLGTH('lngname')'

Re: JES2 vs. JES3
Having worked with both JES2 and JES3 (JES3 first), I would say it depends on what functionality you require. JES3 has some multisystem capability that you may like. If there is no requirement for this then definitely go JES2. JES2 can handle multisystems adequately. JES2 has tended to get support before JES3. Many JES3 systems have been converted to JES2.

Re: CPU Spikes completely hangs sessions;No logons: need inputs
Amit, In addition, if you are running a single JES2 in your SYSPLEX you can display other LPARS in the SDSF DA display using the SYSNAME sysid line command. Alternatively you can use the ISPF Table based RMF II display to monitor the other LPARS in your SYSPLEX by simply overtyping the System ID in the upper right hand corner with the one you want. Depending on your installation you can typically get to this (far superior) version of RMF II with the command ERBRMF, or TSO ERBRMF, and then follow the menus. This is feature is enabled by XCF and does not require a parallel SYSPLEX, but you do need a MAS for the DA SYSNAME to work. I regularly use the RMF II feature in a four system GRS ring.

Re: JES2 vs. JES3
It depends definitely fits here. I would say at this point of the JESes and z/OS, that probably 70-80% of the code is common between them. JES3 has the GLOBAL concept of managing the environment, while JES2 is a collection of LOCAL environments. With MAS, JES2 has certainly become more global in nature. JES3 does have a lot of features over JES2, if you plan to use them. Most sites that I have seen running JES3 run in JES2 mode. JES3 does have the pre-setup requirement, can have up to 255 unique Job classifications, has a built-in Job Scheduler, and definitely has a bit different JCL coding requirements (nothing that can't be overcome). From an operator perspective, JES3 may be a bit more challenging to run (no emails from the seasoned JES3 folks). Many sites that run JES3 are left over from historical environments, and have never changed. You can still find several shops with a single or dual JES3 Global/Local setup. In my opinion this might be a waste of JES3 capabilities. You really need to decide what your JES needs are, and then the right one will fall out for you. And your mileage WILL vary. zNorman -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Lizette Koehler Sent: Monday, September 06, 2010 Monday 4:45 AM To: IBM-MAIN@bama.ua.edu Subject: Re: JES2 vs. JES3 I am sure there will be some opinions on this. But the basic functions of JES2 and JES3 are different. I have only used JES2 and know very little of JES3. So I am a little biased. JES3 has resource functions where JES2 does not. In JES3, as I understand it, a job cannot get into the system unless all allocations are met. However, you can submit a job to JES2 and it could begin to run without all allocations (dasd, tape, etc.) being available. To handle that problem in JES2 you have add-on products like ThruPut Manager, DTS Software SCC, ACS, and so on. So to me the bottom line is more like: JES2 comes with the operating system, but how many more products do you need to add-on before it behaves (okay I will say it) like JES3? I like JES2 because it is simpler in concept than JES3. However, both products have their pros and cons. I am not sure that this can be a apples to apples type of choice. They are both apples, but do you like sweet ones or tart? Do you like Washington or Delicious? Do you like Red or Green?

Going back to the '70s, I vaguely remember a rule of thumb (if you were building a shop or converting from non-IBM to IBM): If you are going to run up to 3 CPUs (basically a Box, or CEC as it would be called today) in a site, you would use JES2 because JES3 Global was expensive (in CPU cycles). If you were going to have 3 or more CECs in a site, you would give strong consideration to JES3. Today, I have been looking at features I was familiar with in JES3 and it appears to me that many of them have been moved to BCP (basic control program) to make SYSPLEX operations easier to do. A good example of this is the change in console support and command routing. From my perspective, and this is just my opinion having NOT used JES3 under z/OS, the only thing that JES3 would buy us today is the JOB scheduler that JES3 had, and Job Set Up. JOB Setup is a foreign concept to anyone who has done JES2 only. And it causes heartburn for people having to provide a JOB stream to/for a JES3 environment. The idea that JES3 and MVS can both manage tape drives/mounts and JES3 requires the data sets to exist before the JOB starts (otherwise you get a JCL error -- UNLESS the data set is created in the JOB via JCL) is hard for some to get their hands around. I have done work for a US Gov't agency, that was running a single CEC with JES3 Global and no locals. As I understood it, they did this because they were dependent on the JES3 job management (job scheduler) system. But they could not otherwise justify JES3. And if they had not been a JES3 shop in years gone by, they would have just gotten a simple job scheduler. I would like to hear from current JES3 users and what they think.

Re: JES2 vs. JES3
before being con'ed into going to POK to be in charge of loosely-coupled architecture, my wife did a stint in the JES group ... including working on spec. for JESUS (JES Unified System) ... taking all the features, that customers couldn't live w/o, from both JES (slightly earlier, she had been part of the catchers for ASP in the JES group). However, the polarization of the two sides prevented much progress being made. in POK, she did peer-coupled shared data architecture ... which saw little uptake (except for IMS hotstandby) until sysplex (contributing to her not staying long in that position; that periodic battles with SNA organization about demands that SNA be mandated for peer-coupled coordination communication). -- virtualization experience starting Jan1968, online at home since Mar1970 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Backups (was Virginia DOT outage)
Richard, How true. I thought this was part of the thinking behind before and after batch back-ups, providing a checkpoint where an application could be restored prior to some application related error or corruption. There are a few sites that use in-system copy products (Shadowimage, FlashCopy, Timefinder, etc) to capture several Point-in-Time copies at regular intervals throughout the day to minimize the time required to restore and roll forward from this sort of error. From what I perceive of this problem, this sort of backup process may not have been compromised, and could have been used to restore the data to a recovery point in minutes, not days. There's a reason the storage vendor's are selling low performance, High Capacity SATA drives - this could be one of them :-) Ron -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Richard L Peurifoy Yes, but with mirroring it is already to late when the change occurs. With a backup you have a chance to restore the bad data if you catch it in time. We do backups every night, and keep them for at least a month. The applications folks do their own backups as well, and may keep them longer. It is certainly possible to not realize the problem until the backup is no longer available, but at least you have a chance. -- Richard -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

And JES3 setup is oblivious to COND, IF, THEN, ELSE, etc, and operates as if every step will be executed, even those in both branches of THEN and ELSE. And it doesn't count if you create or delete a data set in an IDCAMS step -- JES3 setup only understands JCL allocation. And the diagnostics are unsatisfactory to someone minimally familiar with JES3.

Why is JES2 better than JES3? Why is JES3 better than JES2? Why would JES3 be preferred over JES2? Back in the 1970s, it was said that if you had two 168s, you should not even think about JES3, but if you had two 168s and a 158, JES3 would be OK because JES3 would consume a 158's worth of CPU time on its own, leaving the 168s to run the application workload.

Re: The new POO (Props / ProP ) is available
In general, the Principle Of Operations only describes the logical results that facilities are to produce. This allows different models to use different methods to obtain the same logical results. IMO, where possible, IBM tries to hide the actual method that the hardware uses to obtain those results just to keep them secret from potential competitors. I would hope that the TOD clock facility is still fault tolerant. There may still be multiple physical TOD clocks (perhaps not one per CPU or LPAR, etc.), but a reasonable number for redundancy. However, from the view point of each processor there might be only one logical TOD facility. To know for sure, I think you need to bluntly ask IBM if the TOD clock facility is redundant. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Paul Gilmartin Sent: Monday, September 06, 2010 9:33 PM To: IBM-MAIN@bama.ua.edu Subject: Re: The new POO (Props / ProP ) is available On Fri, 3 Sep 2010 16:47:20 -0600, Steve Comstock wrote: http://www- 01.ibm.com/support/docview.wss?uid=isg2b9de5f05a9d57819852571c500428f9a In which I read: In a multiprocessing configuration, a single TOD clock is shared by all CPUs.
