Re: AOPBATCH Continuation character
The ice under my feet is becoming thinner :-) I don't consider myself to be a code page expert, so bear with me and correct me if I'm wrong. I've not played with code pages and assembler so far, so I may be missing HLASM options. If there is such an option for HLASM, an assembler program would need to be recompiled for each locale; no portable load modules. Undesirable. But this is in no case specific to assembler code, is it? The same applies to any program code, compiled or interpreted. If you have literals (or hex constants for the worse) that contain characters which have different code points in different code pages, the behaviour of the program becomes code page depenent. So, how does the PARM='ENVAR(LC_ALL=De_DE.IBM-273)/sh' you suggested work? Does it cause the shell to translate all character data to a standard code page when performing any test? Performance? Well, it's only an interpreter anyway. I don't know what you need to do to provide proper locale support in your program and wasn't curious enough yet to find out. My highlevel understanding is that the shell and utilities are code such that they do support different locales. And they depend on the runtime environment, i.e. Language Environment, to help them achive this. You wrote, AOPBATCH's shell. Does AOPBATCH have its own version of shell, or does it use /bin/sh? What I meant to say is that it is not AOPBATCH but the shell it spawns which supports different locales (see above). The resulting shell will support locales. What programs other than sh are ENVAR()-savvy. ENVAR() is an LE runtime option with the help of which you can set environment variables before your code gets control. It is not bound to nor restricted to the LC_ALL= variable. But, LC_ALL is an environment variable that influences in the LE runtime, not the program (which benefits from this support). Does iconv support UTF-8? Does PARM=ENVAR() support UTF-8? Yes. / Doesn't seem to be the case.

Re: Doubt about Server Pac and Catalogs
You are correct about HFS/ZFS, I mentioned that. Those do get cataloged with the maintenance SYSRES as the second qualifier in the live Mastercat. We have no SMS managed datasets provided by Serverpac(other than HFS/ZFS). CPAC provided datasets get cataloged in the live catalogs with a version/release qualifer. My SMPE targets eventually become the same name as the live datasets, after they get loaded. Hence my comments about removing the requirement for these datasets to be cataloged at all. This is the process: 1) configure serverpac for end state(including end-state dataset names) 2) modify and run ALLOCDS changing all created datasets to add unique HLQ(want to stop doing this if the requirement to catalog them went away) 3) modify and run RESTORE making the same jobs as above (also stop doing this if the job had VOL=SER references to the datasets created above). 4) rename all above datasets removing unique qualifier I realize I could use the SSA to do this, I'm just not a fan of them, and if the vol=ser references were put into the job, there would be no need for the SSA either. Just a few less jobs to run, and stuff to mess with. I use a cloning procedure that copies the maintenance sysres to one of several Live SYSRES volumes that we alternate through. The live dataset are all cataloged indirectly with SYSR1.

Re: TN3270 server offload options
I think I missed something, WHY does the Cicso CIP need to be replaced? At one point in our history, TN3270 was a significant load on our processor (then MP3000). We were using a Cisco CIP for a IP connection, but not offloadint TN3270 (FUD of CIP CPU load etc). We did the offload and saved a LOT of CPU, of course, that box didn't have an OSA. When we went to z800, we replaced the general IP link thru the CIP with the OSA, but we have left the TN3270 on the CIP. OSA is faster than the old way for FTP etc, the CIP 3270 is slightly slower for TN3270, but either are quite acceptable. So, if the CISCO CIP is going away or someting, I may need to onload myself.

-snip--- From my little knowledge, I prefer not cataloging more datasets than necessary in the master. I don't know if this is a wrong positioning. Is it? Nevertheless, my main doubts are the catalogs I should use... -unsnip- Reserving the Master Catalog for the operating system, and as few other datasets as possible, is a good idea. As far as other catalogs are concerned, I like a dsname standard that separates PROD from TEST/DEVELOPMENT as early as possible in the name. That is, in the qualifier as far to the left as possible, ideally in the first qualifier. Then I can direct PROD to one catalog, or one small set of catalogs, and keep all other activity away from it. So a programmer that might mess up a catalog can't affect my PROD workload. Remember that PROD is most often the revenue-producing part of the IT environment; protect it. Don't go overboard defining catalogs; maintenance can get to be a real headache and disaster recovery can be adversely affected.

I do use the software upgrade installation path, as mentioned earlier. Your suggestions of MERGECAT's, SSA's, etc, is exactly what I am trying to eliminate. My goal and am very successful with it, is to just get the datasets layed down, and restored with no catalog manipulation, other than having to uncatalog, and rename the datasets after the restore. No new catalogs, no mergecats, no SSA's, nada. As far as massive editting, is all pretty easy really, as mass changes cover 99% of the cases, and am prepared to continue that method. As far as your comments about relying on the same relative sysres volume, yes you are correct, and when you use your previous Serverpac config to seed the new one, you get that automatically.

Re: Who intercepted SVC 26?
The culprit appeared to be... FDR! That was a surprise to me, so I went digging in the installation parms and discovered that we'd configured it to use a catalog locate exit for auto recall. Guess when Bruce says locate exit he means front-end SVC 26 since there isn't a locate exit anymore. David, you are right. Actually there is still a locate exit - in the SVC 26 module IGC0002F, there is a CSECT IGG026DU which is actually the entry point of the load module. I guess you could say that it was never an exit since that is actually a front-end to the IBM code. But some IBM doc referred to it as the catalog exit.

Re: GDG question
I support a customer where the SMF DAILY and WEEKLY files are GDG-based and we use a relative Julian date (or week of year) to identify the particular file of interest. On days where no processing occurs, it's conceivable to have a stub generation created. A new year requires creating a dummy or starter/adjustment generation until that first daily or weekly job completes, then delete the stub, if required. Possibly, a similar technique could be used if the generation # represented a **.GmmddV00 naming pattern, though it would be necessary to insert a dummy generation **.G0200V00 and so on, then maybe go back and delete the stub generation. Obviously daily generations for different years (using the mmdd technique) would not be able to span years. So, as I mentioned, this technique works well with Julian dates for a daily file and also a week of year (weekly being named **.GyywwV00), though some admin is required at the start of a new year. Suggestions for using derived JCL SET symbolics using some standardized naming convention have been mentioned previously on this forum and I would consider that the same could apply in this application but clearly with some research, test scenarios and well-documented restart/recovery procedures.

Re: TN3270 server offload options
It's old news, but the NICs on MP3000's were advertized as limited, not for production load. IIRC, I think maybe 7-9 Mbit even though they were physically 100Mbit. Weren't they emulated by the OS2 code? The OS2 emulation would probably bottleneck bandwith before TCPIP CPU was an issue. The team that sized our R25 replacement MP3000 said we should NOT use those NICS. Our metric was that TCP/IP was using as much CPU as our medium CICS regions fed thru TN3270. Look at the paths thru the dispatcher saved in offloading. Offload trafic is LU, enters VTAM, exits VTAM. Onboard TN3270 adds trips thru the TCPIP stack. Our peak loads were driven by 3270 traffic, when load increased, TCPIP, VTAM, SuperSession, CICS (x5 prod regions) and IMS ALL increased at the same time. We were marginal but OK until we had to SSL encrypt TN3270 traffic (No crypto co-pro). With the CISCO CIP, there are Cisco content switches beyond the CIP that are doing encryption. THey were already there for PeopleSoft and other web traffic, so no cost to us to use. The CIP can encrytp, but Cisco FUD says it's limited as well. I suspect it would limit out faster for web SSL, but 3270 transactions are usually less than 2k bytes. Interesting. Not long ago, we also had an MP3000. No OSA, but it did have three NIC's that worked just like OSA's. I don't recall the TN3270 load being noticeable, let alone significant. We did a boatload of other IP traffic, but, again, no noticeable load.

We did the offload and saved a LOT of CPU, of course, that box didn't have an OSA. When we went to z800, we replaced the general IP link thru the CIP with the OSA, but we have left the TN3270 on the CIP.

Bruce, There isn't much of a mainframe market in India, probably because IBM was non-existent there for all of the 80's. In the last eight years of going to India I have been to one Mainframe site. It's one place where there is no shortage of mainframe talent, as there are virtually no mainframes sites that require it.

Re: Cascaded FICON and HCD
To the best of my recollection In HCD, you define the following: CHPID 11 -- SWCH1 22 (CHPID 11 is plugged into port 22) and SWCH2 33 -- TAPE DRIVE (tape drive is plugged into port 33) The SWCH1 -- SWCH2 ports and data paths are defined within the two switches, not in HCD. HCD doesn't know if all the data runs across 1 pair of connections, or 10 pairs of connections. At least, that's how I think about it. Brian On Thu, 1 Feb 2007 21:45:15 +0100, R.S.

Re: Cascading FICON director with DASD and TAPE devices
Bruce, My recollection is that tape drives would use DC Interlock mode and when all you had was a primary and secondary BT channel this would seriously impact the DASD. I think the 3480 was the last drive that wasn't pure Data streaming. On ESCON running data streaming a tape drive has no significant impact. When I look average connect times for cartridge drives about 10 years ago they were no different than disk drives, and smaller than work packs where sort was using CFW. I've mixed tape and disk on ESCON in the past and found no problems by doing this. Mixing them on FICON is a no-brainer.

We don't happen to mix tape and DASD on a chpid, but it's apparently more out of long-standing habit and housekeeping practices than concern for the vagaries of modern technology. back in the days of unbuffered round tape, mixing tape and disk was a no-no. Some tape operations took a long time, which locked out disk I/Os since the channel could handle only one operation at a time. Buffered tapes on ESCON channels are not so bad, but still some tape operations can take a long time, and ESCON still supports only one operation. I expect that FICON, since it handles parallel I/O operations, would not be as big an issue. But I would still be reluctant to mix tape and disk on a CHPID -- Bruce A.

I have the assistance of a job scheduler which can substitute variables in JCL to help with this idea, so bear that in mind. I want to create twelve GDGs, prefix.whatever.JAN, prefix.whatever.FEB and so forth. Then, instead of creating prefix.whatever.JAN(+1) I want to create prefix.whatever.JAN.G(day-of-month-with-leading-zeroes)V00 with DISP=(NEW,CATLG). In essence one generation per day of month, with missing generations if we don't run that day (state holiday or whatever). Then I want to be able to read prefix.whatever.JAN as the complete set, as you can do with GDGs. Are there any holes in this theory that I'm overlooking? SNIP I'm a bit hazy on this, but as I recall from doing this with SMF merging in a JES3 shop from many years ago: In your GDS build, you can have two or more files with the same Generation (G). However, you must have different Version (Vnn). The highest numbered version of the GDS takes precedence. So as another poster suggested, you can have a dummy entry (say ...G0001V00), and over-ride with ...G0001V01. Again, as someone else questioned for a rerun, if you need to rerun but NOT do a delete, you can create the GDS with (as an example) G0015V02. When you pull in your GDG, the highest numbered Version of a GDS is what you get when referencing all. Caveat: The preceding was based on DFP BEFORE SMS. Now, based on the SMS comment by someone, you can create 1 track GDS with V00 that are empty (OPEN/CLOSE w/ no write/put). Then the real ones can use V0x. SMS shouldn't have a problem with holes, because there won't be any. But you will take up space for a dummy file for each day of the month for each month of the year.

Re: Cascaded FICON and HCD
In the olden days I referred to, we utilized two entirely disparate technologies (although companies eventually conjoined in an arranged marriage) for ESCON channel extension: - NSC: a half-software, half-outbound-hardware solution - CNT: a 100% outbound-hardware solution Each product could convert a mainframe I/O at site A into a bundle of TP packets, transmit them to site B, and reconstruct them so that they appeared to the recipient as a locally generated I/O. Each product, in its own disparate way, allowed for the definition of a switch at site B, effectively providing doubly switched I/O: the first one managed at A by MVS, the second managed at B by the channel extender. When we first began to convert to FICON over DWDM, cascading was still a gleam in the eye of its architects. The mechanism for two switches was built into the I/O protocol, but gismos required to implement cascading were not yet on the market. So we struggled along for a while with more DWDM links than we wanted until the new switches became available. Now both switches are defined natively in the IODF. We have computers and peripherals both sites. Everything talks together as if there were a single glass house. As I've said before in this forum, ESCON is an absolute disaster over DWDM at 100 KM. That's why FICON was brought in--even a little ahead of its time.

Re: Cascaded FICON and HCD
Um, I think I missed the point of the question with my earlier post. Thanks to Ron and Tom for providing the actual answer. An important characteristic of DWDM is that it's 'content unaware'. It doesn't know the nature of the data being transmitted any more than the pipes in your house know about water quality. Traditional channel extenders are all about mainframe I/O--up to and including simulation of ESCON switches. P.S.
