Re: [IBM External] Re: IPL's POR's frequency
If you have a fully configured parallel sysplex, disruption to clients should be minimal. On balance, less disruption than a system crash caused by downlevel maintenance.

Re: [IBM External] Re: IPL's POR's frequency
One of the things that you "lose" when only IPLing once or twice per year is the ability to install maintenance on a more frequent basis, at least anything but individual fixes. To try to install an RSU upgrade without an IPL will be very foolish. As we previously stated by me and others, your maintenance schedule would have impact on your IPL plans. :) If you have a client that wants to stay at quarterly RSU levels, then you would be most likely be going to IPL quarterly Brian -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: clist substring command
Yes, SET SYSSCAN=0 is the same as SET &SYSSCAN=0.
By default, SYSSCAN=16. If it is overridden as, say, SET SYSSCAN=2 then
SYSSCAN=2 remains in effect until it is overridden again or restored to
its default value SYSSCAN=16 (which always applies, by default, unless
overridden.)
"You can assign &SYSSCAN a value from 0 to +2,147,483,647 (2³¹-1)" - not
quite: SYSSCAN can be set to 1 or 3 etc. if/as required. I have never
used 2³¹-1.E.g. Use of SYSSCAN = 1 & 2:
/* ALLOW FOR & OR ARITHMETIC OPERATION CHARACTERS IN &CO AND &PI */
SET SYSSCAN = 1 /* <-- e.g. HERE */
ERROR DO
SET SYSSCAN = 2 /* <-- e.g. HERE */
SET COMM&T = &STR(&CO)
SET SYSSCAN = 1 /* <-- e.g. HERE */
RETURN
ENDO
SET COMM&T = &CO
SET SYSSCAN = 16
ISPEXEC VPUT (COMM&T) PROFILE
In practice SYSSCAN would be set to whatever is appropriate, as in e.g.
DO I = 1 TO 999 WHILE &MAXCC = 0
ISREDIT (DATALINE) = LINE .ZCSR
SET X = &SYSINDEX(&STR(,),&SUBSTR(1:27,&DATALINE),19)
IF &X = 0 THEN +
DO
SET MODULE = &SUBSTR(19:22,&DATALINE)
SET PREFIX = &SUBSTR(24:27,&DATALINE)
ENDO
ELSE +
DO
SET MODULE = &SUBSTR(19:&X-1,&STR(&DATALINE))
SET PREFIX = &SUBSTR(&X+1:&X+4,&STR(&DATALINE))
ENDO
SELECT (&PREFIX)
WHEN () SET MODULE = WHAT&MODULE
WHEN (WOT1) SET MODULE = WHB1&MODULE
WHEN (WOT2) SET MODULE = WHB2&MODULE
OTHERWISE
ENDO
SET J = &SUBSTR(&LENGTH(&I):&LENGTH(&I)+3,000&I)
ISREDIT LINE_AFTER .ZCSR = +
DATALINE "&STR(.C&J ANOP )"
SET SYSSCAN = 2 /* <-- e.g. HERE */
ISREDIT LINE_BEFORE .ZCSR = +
DATALINE "&STR( AIF (NOTRACE EQ 0).T&J)"

CICS VSAM LSR pools and IBM DASD PPRC type mirroring.
Hello, all. I don't know if any of you are doing disk replication to a DR site, but we are, and we are trying to resolve a specific problem with CICS and VSAM file. CICS, in the case of LSR pools hold the data in the buffers until a buffer shortage\wait type of condition occurs. When that happens CICS flushes the buffers and updates the high used RBA's of the files. In the case of a DR test. We use the data as is. We copy the current replicating data to other DASD so that we can perform the test by bringing up the system and testing it. Well the only way we can think of making sure we get all the VSAM data is by closing the files at the production site which is not feasible. Is anyone else doing this kind of mirroring, and are there things you are doing that fixe the VSAM buffering problem? The only thing I can think of doing is adjusting the LSR buffer pools so that waits occur every so many minutes, I'm staying away from share option 4,4 on the VSAM files which are a real performance hit. Any takers are welcome. Also as an aside the implication here is that in the case of a real disaster there is data missing from the VSAM files, or am I wrong and full of it?

Re: at what point does CICS signal Db2 that the thread is to be closed. Db2 will close the thread and write the accounting record.
Bill, DB2 will hold the thread open for a short time waiting to see if it can be reused. It's expensive to create/destroy threads. Do you have Omegamon, or CICS/Mon, or some other monitoring tool, mostly for CiCS? If so, take a look at those transactions and I think you'll see the DB2 time is very small (DB2 is unbelievably efficient these days), but CICS will have some latency like transaction creation/termination, if cross-memory services are being used, there's a cost for that. You should probably see the vast majority of that 30-50 seconds spent in CICS internally, though CICS' actual CPU time will be very small also. CICS is quite efficient, too. The last CICS/DB2 shop I was in had extremely quick internal times for CICS and DB2, but the entire transaction would easily take several seconds due to transaction routing, cross-memory services, etc. 30-50 seconds sounds pretty extreme, though. There may be some tuning opportunities on the CICS side.

at what point does CICS signal Db2 that the thread is to be closed. Db2 will close the thread and write the accounting record.
This is a question about at what point does CICS signal Db2 that the thread is to be closed. Db2 will close the thread and write the accounting record. Situation: DB2 SMF accounting records are showing subsecond Db2 time, and elapsed time of 30-50 seconds. The caller is CICS, on the same LPAR. Db2 is waiting for something before the thread is closed. The possible candidates for the latency are: VSAM I/O subsystem Network DB2 systems programmer is trying to diagnose with the assistance of CICS Systems programmer. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: The Business Case for Pipes in the z/OS Base (was: Re: REXX - Interpret or Value - Which is better?)
Yes, checkpointing is increasingly important in a high volume workd, but it is also increasingly more difficult. There is an OS facility for restarting from a checkpoint, but it has significant restrictions and I wonder whether it has been used in the last half century. -- Shmuel (Seymour J.)

I misplaced the original post, but somewhere in this thread someone commented that checkpointing is less important. I think I disagree, so just a quick comment from me. Yes, absolutely, there's much more computing power and much better I/O. There are also lots of efficiency gains -- much better compilers, for example. However, if anything the data volumes and related requirements are growing even faster. We've also seen recent, real world incidents involving major organizations failing to meet batch processing deadlines with serious consequences, in some cases to whole national economies. My anecdotal observation is that checkpointing is becoming more important at least on z/OS, not less. By sheer coincidence I'm having a technical conversation this afternoon that (when you boil it down to its essence) is "please implement a certain type of checkpointing." I interpreted this particular remark as a side comment, not really anything that genuinely affects whether pipes are useful in some cases. Yes, pipes are useful.

Re: [IBM External] The Business Case for Pipes in the z/OS Base (was: Re: REXX - Interpret or Value - Which is better?)
There are lots of things that breaks pipelines - and so recovery is a necessary thing to think about and build in. I guess the difference between Pipes and pipes :-) is one of granularity.

Sent by:"IBM Mainframe Discussion List" Paul said: > I'm guessing the atypical case is a stage such as FANOUT which necessarily copies the data. Not sure what you mean by atypical. FANOUT is typical in the respect that it doesn't create an actual copy of the input record. It just looks like it. FANOUT, and non-record-changing stages, pass the same input record pointer to their downstream stage(s). This is what makes Pipes so efficient. No working set expansion and less reloading of just purged cache data. OREXXMan Would you rather pass data in move mode (*nix piping) or locate mode (Pipes) or via disk (JCL)? Why do you think you rarely see *nix commands with more than a dozen filters, while Pipelines specifications are commonly over 100s of stages, and 1000s of stages are not uncommon.
