Re: I need to assemble RSCS exits

I've been told that we need to be off the old release of RSCS by the end of June or we'll incur a monthly fine. Apparently you discontinued your license to use RSCS v3.2 a bit too early. RSCS is now packaged with the base OS. Packaged, yes, but you still have to license the RSCS feature to use the NJE/RJE functions. Seems like ProgDir shouldn't use it [HLASM] in the examples. It is getting more and more difficult to maintain compatibility with Assembler F. We feel justified in using z/Architecture features and functions, as well as things as simple as long variable names or mixed case. This is especially true of things that talk to CP. None of that, not even AMODE/RMODE, are understood by Assembler F, yet AMODE/RMODE are important in virtual machines 16MB. If you write exits for IBM products, you need to seriously consider a modern assembler. As others have noted, HLASM isn't your only choice. Am I headed in the right direction, or am I wasting a lot of my time? If I get my exits assembled, how do I get the FL540 RSCS to hook them in? Appeal to your IBM rep. If you have licensed the RSCS feature of z/VM 5.4, then they may be willing to let you run RSCS v3.2 (unsupported, of course) for a reasonable migration period. Or perhaps you are already at the end of an agreed-to migration period? Alan Altmark z/VM Development IBM Endicott

You will cause SFS server initialization failures (message DMS3135E). Any filepool whose name does not begin with VMSYS will be a global filepool. If you don't authorize the server to do the thing that it has been configured to do, it will complain and die. By selecting a name that doesn't begin with VMSYS you have instructed SFS to define the filepool as global resource. I ask because I notice that VMBACKUP owns a filepool that has IUCV *IDENT LOCAL set, with a name that does not begin with VMSYS. I haven't been able yet to learn anything about this particular pool, though, or how it's used, so I accept that it is possible for it to have some operational characteristic that makes this possible, where it wouldn't otherwise be generally. Whatever VMBACKUP owns, then, it isn't a filepool. Not all resource names (QUERY RESOURCE) are SFS filepools. Alan Altmark z/VM Development IBM Endicott

Re: I need to assemble RSCS exits
If is very probably the local RSCS exits were written long enough ago that an older assembler will work just fine. Since you were able to assemble cleanly this is most likely the case. And yes, you do need to reassemble the older exits with RSCS FL530 or FL540 otherwise they will abend. I hope you are still licensed for RSCS 3.2 and have obtained an RSCS FL540 license as well. Best Regards, Les Geer IBM z/VM and Linux Development Yes, we are fully licensed for RSCS. I realize that the timing could have been better, but I didn't order the new release. That was done by my predecessor, who quit suddenly. For legal reasons I can't contact that person. Regardless, I am now in the situation I'm in. In looking back on our old system, I don't think the exits were re-assembled; rather they were re- linkedited. The TEXT files have a pretty old date, but the EXITLIB LOADLIB is much more recent. The option to use the new FL540 of RSCS came from IBM from an ETR I opened. Not their first piece of advice. This morning I compared my newly-created TEXT files from my assemble and except for the date they are the same, so the assembler seemed to work. I'm fairly certain these exits are in use. I used a tool called Track to look at RSCS virt storage on our 5.2 system, because I was also curious about that. It shows: Base= Real address=0001B2F99400 Vaddr Offset Hex Ebcdic 4400 +004400 1000 C5E7C9E3 D3C9C240 * EXITLIB * 4410 +004410 D3D6C1C4 D3C9C240 *LOADLIB * The EXITLIB LOADLIB is the customized library. Dave, thanks for pointing me to the Exit manual. I did manage to find the correct PROFILE GCS on the 5.2 system and it does indeed point to EXITLIB. I'm new enough that I still have trouble locating proper files. The Exit manual also mentions the HLASM several times. Alan, I understand the reasoning behind using modern assemblers, but I spent more time than I needed to trying to figure out why I couldn't use the one specified in the manual. Thanks again for your responses. I'll let you know if I have any sort of success.
Change of Status
This is just a short note to let my friends in VM Land know that as of tomorrow, I will no longer be working for Mainline Information Systems (who took over Cornerstone Systems six months ago). Between the economic downturn and Mainline's lesser interest in small mainframes they decided that they don't need my talents any longer. I have several irons in the fire and hopefully one of them will work out in the near future. In the meantime, I will continue to monitor this forum (although from a different address) and contribute on the rare occasion when I can add something to the discussion. Mike Hammock

Re: Remote Drives
The 3270 will be at the end of a different 1000 mile wire. The move to the DR site will be as you describe.

Re: local filepools
By using an entry in the SCOMDIR NAMES file, you can assign a real, unique, filepoolid to each server, but keep the name the users are used too. E.g; :nick.oldpool :tpn.uniquepool But, it is then required that during an IPL CMS session, you use the same name to refer to the pool, either the unique one, either the old name.

Re: local filepools
Not exactly. Any filepool that does not start with VMSYS is eligible to be made global, but it doesn't have to be. You have to specify REMOTE in the DMSPARMS file before it becomes global. Without that, it is local. You think that IBM would not allow user created filepools that are local? Have you been borrowing cough syrup from Adam again? Adam, check your supply.

Re: Remote Drives
I only have 1 LPAR that can handle the remote tapes at the production site. I do not think that doing it in a virtual machine would be helpful in that it would be the VM CP handling the I/O requests, not the bare iron. I will have to schedule an outage some weekend to try it. How easy that will depends on whether it will take manual intervention at the DR site to mount the tape. The operators there are stretched thin due to a pending data center move. If a tape that is mounted and at load point will survive a SHUTDOWN, I can do something like this: 1. Log on to the non-dr system 2. Have VMTAPE mount the stand-alone tape 3. DETACH ... LEAVE the tape 4. SHUTDOWN 5. IPL the s/a tape. 6. Following the experiment, IPL the VM system. Here, the only operator intervention would be the two IPLs - I do not have access to the HMC to do them. That operator is not at the center being moved, and it doesn't involve abnormal processes (opening the silo and manually mounting a tape), so it is much easier to schedule.

The move to the DR site will be as you describe. The assumption is that we are moving there because our normal center has been destroyed (used as a set for an episode of 24, perhaps). The move to the DR site will have local tapes and 3270s on a 3000 mile wire. After f few months, when the normal center as been reconstructed, it will have brand new everything. One way to accomplish the move might be to do a reverse DR using tapes that are located at the normal DR site. Might is a key word here. If the stand-alone utilities can be IPLed from there, there would be no physical transport of tapes, something that our powers-that-be are rightfully paranoid about. Alternatively, we could find some way of creating any needed S-A utilities at the new center.

I can tell you in our old building (back in the Sterling era) we had remote tape drives in Reston going to our datacenter in Sterling (probably about 15 miles) and I personally did this with that configuration. That being said, admittedly for 99% of customers doing remote DR exercises it's the 3270 that is at the end of the 2000 mile wire, not the tape drive ... the tape drive is local (channel attached) to the CPU.

I think it would be a timing problem mostly -- can the device deliver data in the expected time frame for IPL to look valid -- but I suspect there's going to be no real reliable answer across the board. If you can attach a device to a spare LPAR or a virtual machine and try it, I think that's your only way to get a real answer.
Re: Remote Drives
Spare LPAR? Surely you jest. What with z/TPF and Linux, every spare byte of memory is allocated. Some times, when MVS isn't chewing up a lot of bandwidth, we get as fast or faster response from the remote site. I presume that is because the SL3000 buffers data and gives immediate responses. When the network has spare time, the tapes can be driven at nearly their capacity. Like I told Dennis, I do not think that attaching the drive to a virtual machine will give useful results. CP manages the I/O and the IPL sequence is emulated. The only real test will be to IPL in an LPAR. That will involve the HMC and a real IPL sequence, which are the really big question marks.

Thanks, Kris, this actually looks like exactly what we want to accomplish. I'll give it a shot and follow up with how it all ends. I'm learning a lot.

Is there anything that is really stopping me from changing the IUCV *IDENT GLOBAL to IUCV *IDENT LOCAL for the two filepools on these three nodes, and then moving on? Yes. You will cause SFS server initialization failures (message DMS3135E). Any filepool whose name does not begin with VMSYS will be a global filepool. If you don't authorize the server to do the thing that it has been configured to do, it will complain and die. By selecting a name that doesn't begin with VMSYS you have instructed SFS to define the filepool as global resource. I ask because I notice that VMBACKUP owns a filepool that has IUCV *IDENT LOCAL set, with a name that does not begin with VMSYS. I haven't been able yet to learn anything about this particular pool, though, or how it's used, so I accept that it is possible for it to have some operational characteristic that makes this possible, where it wouldn't otherwise be generally. Whatever VMBACKUP owns, then, it isn't a filepool. Not all resource names (QUERY RESOURCE) are SFS filepools.
