Differences between CPU values from SMF30 and DB2 stats
Dear all, I am a DB2 specialist , doing some measurements i just noticed that there is a noticeable difference between DB2 CPU times i got from SMF30, and the times i got from the DB2 statistics records (SMF100) about the CPU consumption of DB2 address spaces. I submitted the question to various performance specialists at IBM (authors of presentations at CMG ...) but none of them noticed this before. This is the second MVS site that i notice the differences , so i don't think that there is a bug behind that.

Re: RACF User ID resumed without an SMF record?
Greg, If the RACF database is shared across several LPARs, does the input to your daily RACFRW report include SMF data from all the LPARs? If SETROPTS AUDIT is not active for class USER and the OWNER of this CICS ID is a non-SPECIAL USERID, the later could execute an ALTUSER that wouldn't be logged. Another possibility is this ID was being listed as REVOKED by LU because it had crossed the threshold set by SETROPTS INACTIVE but was able to logon via some mechanism that circumvented the INACTIVE limit. Here are some related questions. 1) Do you have SETROPTS INACTIVE set and to what number of days? 2) Was this ID listed as REVOKED prior to July 8? 3) Do you have a backup copy of the RACF database prior to July 8 from when the ID was showing up as REVOKED, and if you generate an IRRDBU00 database unload from this copy, does it show the ID as REVOKED? (An ID displayed as REVOKED by LU due to INACTIVE will not show up as REVOKED in the unload.) 4) What is the nature of this ID and how is it likely to be used? Is it hardcoded in any CICS CSD resource definitions such as those for SESSION, CONNECTION, TDQUEUE, or TERMINAL? Is it coded as the USERID in any EXEC CICS START commands within a program? Might Digital Certificates or PassTickets be involved in logging it on? 5) Do you have multiple RACF databases and is this ID defined and active on these other databases? Was it active on another system around the time of this logon? 6) What are the full details of its logon on the 9th. Does it show an associated TERMINAL, APPL, or JESINPUT node? (If it shows JESINPUT, then we might want to explore your RACFVARS RACLNDE profile and NODES profiles.) Regards, Bob Robert S.

Hello group, Does anyone know of a method to resume a RACF revoked ID without having an SMF record be written? We produce a daily listing of RACF commands from our SMF type 80s (using RACFRW) and we list ADDUSER ADDGROUP ALTUSER ALTGROUP CONNECT DELUSER DELGROUP PASSWORD PERMIT RALTER RDEFINE REMOVE. We also produce a daily listing of our CICS user IDs and their RACF status. On July 8 we had a user ID on our report that was listed as REVOKED and a LAST-ACCESS date and time of 07/17/07 17:01:28. On July 9, the report showed the ID was no longer revoked and the LAST-ACCESS reported as 07/08/13 19:24:14. However, our SMF report listed no ALTUSER command or any other command against this ID. (No DELUSER or ADDUSER, for instance). I dumped the SMF records for both July 7 and July 8 and ran a RACFRW to list all the records and there is no reference to this User ID. I'm a sysprog, so I can't blame it on magic or elves - I could try blaming it on the software, but I'm finding that hard to believe - so I have to think there's something I'm missing. I've just looked at everything I know to look at. (Did someone modify SMF for a period? No. Does the COBOL program that lists the RACF users have a bug in it? No.) If anyone has a suggestion for what to look for, I'd appreciate hearing about it. Thanks, Greg Shirey Ben E.

Re: RACF User ID resumed without an SMF record?
Yes, if we had the time, we would rewrite the job to use the output from IRRDBU00 instead of parsing LU * output. We'll probably have the time when IBM changes the output, of course. :-) In any case, thanks to those who made suggestions here and off-list. The problem does appear to be in the process that reports the revoke status, not with RACF. So, the ID is not getting resumed without an SMF record being written, it was not revoked to begin with. At some point later, then, the job that interprets the RACF output gets it right. At least we have something to go on now rather than speculating about SMF. Regards, Greg Shirey Ben E.

In general, there will be very little CPU time recorded in the DB2 Address Spaces, except for the DDR address space, because CPU time consumed in DB2 is recorded in the address space OF THE CALLER, i.e., the Batch Job or the CICS region that called DB2, so the SMF 101 (DB2ACCT) data is the only safe source of who is consuming DB2 CPU time.

R: Differences between CPU values from SMF30 and DB2 stats
Hi all This is a snapshot of a paper I wrote a couple of years ago. May be it can help ... Unfortunately I could not attach the graph because of List rules but results using SMF 100 are just a little bit lower than using SMF 30 OR 72. Best regards Fabio DB2 overhead for MSTR, DBM1 and IRLM can be easily evaluated using SMF 30, 100 or 72 records. a) Using SMF 30 interval records (subtype 2 and 3); you have to select the records belonging to MSTR, DBM1 and IRLM address spaces and sum the CPU time provided in the SMF30ICS, SMF30ICU, SMF30HPT, SMF30IIP, SMF30RCT, SMF30CPS, SMF30CPT fields; b) Using SMF 100; you have to use the QWSAEJST and QWSASRBT fields. A section for each DB2 system address space is provided, so to get MSTR, DBM1 and IRLM overhead you have to sum the values corresponding to all of them2. Remember that these counters have been accumulated since DB2 was last started. So a de-accumulation step is required to get the numbers relative to the analyzed period of time. c) Using SMF 72 records requires a preliminary assignment of DB2 system address spaces to specific WLM service or report class. Then you have to: 1. select the records belonging to these classes; 2. normalize zAAP and zIIP service units, provided in the R723CIFA and R723CSUP fields, to standard CPUs speed multiplying respectively by the R723NFFI and R723NFFS coefficient (they normally have the same value) and dividing by 256; 3. subtract normalized zAAP and zIIP service units from the service units provided in the R723CCPU field; 4. convert TCB and SRB service units values in R723CCPU and R723CSRB to CPU seconds multiplying by the system service units per second value and dividing by the TCB and SRB coefficients (provided in the R723MCPU and R723MSRB fields); 5. sum the values obtained in the previous step to the values provided in the R723CIIT, R723CHST and R723CRCT fields. We applied all the methods described above and we calculated the DB2 System Address Spaces overhead using the following variables: • AS100OVH, based on SMF 100 records; • AS072OVH, based on SMF 72 records; • AS030OVH, based on SMF 30 interval records. The graph in Figure 1 allows us to compare the results we obtained.

Re: The z/OS V2.1 Migration PDF available
Howdy Marna, I like it so far. I thru the chapter 1 and 2, starting 3. Did not even print out chapter 4. Saved some trees that way. And yes, sorry, I still need to print, highlite and note take with pen and highlighter.

Re: C issue - 'struct stat'
I thought about what you guys have told me and realized that while you are correct and it is easy to just run the configuration, etc., the work I've done (shortening the functions' names to 8, upper case characters, COBOL API, etc.) is very valuable to those who are still in that environment. And these guys are my intended audience! To those who just build the thing in USS, please have a look at my config.h for some things that are not necessarily available otherwise. I hear about ports that are done to other open source (I read MVS-OE as well) and this is encouraging, but I wish that those who do those ports should make their ports (with the z/OS related changes, minor as they could be) available in some way, similar to what I am doing.

Re: The z/OS V2.1 Migration PDF available
The migration specific format is nice, however, for online reading the dual columns cause the reader to constanly page up and down to read each page.

Re: The z/OS V2.1 Migration PDF available
I haven't checked yet, so I don't know it's already there. It'd be nice to have a brief chapter in the migration guide that explicitly lists/points to all the previous migration guides that one ought to review for migrations from any/every arbitrary release pre-z/OS 1.12 to z/OS 2.1. That would be useful information for trailing shops whether it's a big bang migration or a stepwise migration.

Multiple timezones?
zVM 6.1 (6.2 coming) The system runs with a UTC timezone, but it would be convenient if I had a userid that could run in a different time zone. UTC doesn't change with Daylight Saving Time, and I have a process I want to schedule at a specific time that is subject to DST changes. i.e. I want something to run at 3:00 AM Pacific Time, in summer and winter. If I can have a disconnected service machine running in the proper timezone, then a simple (k)wakeup exec can do what I need at the correct time. I thought TODENABLE might give me a clue, but I don't want a different time, I just want a different view of the same time. :-) Or, I just have to write my own little time calculator to make the adjustment... Not a difficult thing, but if there's a wheel I can use...
