DB2 and WLM Service Class
Hi, I have one Db2 utility job is running in a service class (vel 50, imp 4) anthr db2 utility job in a service class(vel 30,imp 4). Does Db2 give them same service, if other factors remain constant? Both the utility jobs are doing the same thing.

DB2 and WLM
I am getting a request from my DB2 guy to set up WLM and make appropriate RACF entries for something that is optional in 1.7, required in 1.8, and, I think, dropped in 1.9. Something about stored procedures and separate address spaces. The FM's I've searched don't give me a clear picture of what is what. We don't use stored procedures, so I am a little confused why we have set up that envionment. Can someone point me to a FM that will lead me to the path of enlightenment? Thanks!!

Re: DB2 and WLM
Something about stored procedures and separate address spaces. The FM's I've searched don't give me a clear picture of what is what. First, Stored Procedure Address Spaces have been replaced with Distributed Data Facility (DDF) address spaces. SPAS is still supported, but IBM recommends that you use DDF.

Maybe he can tell where he's reading from. If you're not using stored procedures, he might be doing DDF ie. JDBC, etc. DB2 stored procedures are moving from being run in the DB2 SP a/s to separate WLM address spaces ie. DB2 SPAS is now deprecated. (your para 1 except DB2 v6, 7, 8) For WLM managed, stored procedures, you need a WLM ApplEnv so the a/s will get started/stopped per demand. (I believe that it's 2hrs inactivity before the last STC disappears.) We use the STDATA in Racf Class(Facility) to provide the proper userid. friendly *Warning*: don't include NumTcbs in the ApplEnv Parm as shown in examples. Instead, leave it for the JCL proc where it can be easily changed without requiring a WLM policy activation each time. Only place items that are invariant (rock solid, unchanging) such as DB2SSN and ApplEnv. ps. I believe there are sample stored procedures - and maybe a Rexx builder - provided with DB2.

Re: DB2 and WLM
Since it seems to be my mission in life... Stored procedures run in stored procedured address spaces. This is true whether the requests are are made locally to the system (or plex), or received remotely via DDF. There used to be a single subsystem address space commonly known as SPAS. The newer alternative is called... *** WLM-managed stored procedure address space *** A set of one or more WLM-managed stored procedure (started task) address spaces of a given name are known as an application environment. See option 9 on the WLM main menu. Countless hours of confusion could be eliminated by using the terminology precisely as it is used in the literature. db -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Hal Merritt Sent: Tuesday, March 18, 2008 2:18 PM To: IBM-MAIN@bama.ua.edu Subject: DB2 and WLM I am getting a request from my DB2 guy to set up WLM and make appropriate RACF entries for something that is optional in 1.7, required in 1.8, and, I think, dropped in 1.9.

Re: DB2 and WLM
Wrong. Stored Procedures continue to run in Stored Procedures Address Spaces. They are stored procedures, and they run in address spaces. Stored procedures do not run in the (one and only one per DB2 subsystem) DDF address space. In the original DB2 support for stored procedures, all stored procedures ran in a single DB2 managed SPAS. This address space was started (optionally) at DB2 initialization, and all stored procedures ran in this address space. However, with later releases of DB2, support was added for executing stored procedures and user defined functions (UDF's) in WLM managed stored procedure address spaces, by defining DB2 specific WLM application environments. However since these are DB2 specific, they are still stored procedure address spaces. What is no longer recommended (and for DB2 9, not supported) is the DB2 managed SPAS, so all stored procedures must run in a WLM application environment. One requirement for WLM stored procedures is the use of RRSAF, in ! place of CAF for DB2 connectivity. RRSAF requires that the RRS logstreams be defined, which in turn require SYSPLEX definitions, even if in MONOPLEX mode. With DB2 9, SQL stored procedures can be defined as native which allows them to run in the DB2 DBM1 address space rather than in a WLM address space.

SYSMDUMP in DB2 SP WLM
We need to collect a SYSMDUMP from a DB2 SP WLM task. The SYSMDUMP DD needs to point to a disk data set. There can be multiple instances of the DB2 SP WLM task running concurrently, so there is a need to uniquely name the data set for the SYSMDUMP. GDGs don't work because there is an enqueue on the GDG base, so started tasks after the first wait. We've thought of using system symbols (since this is a started task), but there isn't enough granularity in the values of the symbols to assure uniqueness. Any thoughts on how to accomplish this?

Re: SYSMDUMP in DB2 SP WLM
After further research I see that the 'corruption' is the insertion of carriage control characters. This is being done by SDSF when using line command XDC, even if the correct data set attributes are specified for the output data set. Instead, I created an appropriate data set, allocated it to some DD in my TSO session, then used SDSF's XFC line command and pointed to that DD. This copies it as is, without carriage control characters. Now it is usable. Thanks Wayne and Ed.

Re: SYSMDUMP in DB2 SP WLM
(off-list to hide my ignorance) Hello Ed, Out of curiosity, in a situation where multiple abends occurred, how does SYSMDUMP processing handle this? Does it write multiple dumps to the dataset? (I'm guessing yes because of the nature of SYSOUT storage.) We just had a situation where, in a multi-TCB address space, the customer had only SYSUDUMP. The problem was SP 0 fragmentation below the line, and unfortunately we only got SP 0 storage associated with the two TCBs that RTM decided to dump, which you can guess made things difficult for me to track down. Luckily a couple of days ago we got another dump, from another customer, with the same below-the-line storage issues, but luckily the dumped SP 0 had a lot more info. A SYSMDUMP would have come in very handy in those environments. (Now I'm fighting an internal battle between SYSMDUMP and SYSABEND. One of our support reps has some REXX programs he's written to parse SYSUDUMP/ABEND, and I'm trying to bring them into the late 1990s with IPCS and re-writing the REXX programs to do the same thing.) Also, I'll ask just because, but does Phoenix have any openings? I like what I'm doing, but there are some issues within the company that are making me wonder if it was a good thing to take this position so quickly. Thanks and best regards, Ray Mullins -- M.

Re: [DB2-L] WLM Service Definition for DDF Thread
Great tips -- thanks all. Using RMF screens (which I have access to) and looking over someone's shoulder for WLM screen's (which I don't have access to) I found that my assumptions were basically correct, but that I was looking at the wrong thing. Our production DDF thread rules are: 1 SIDBP1 2 . PN . *DDFPROD (Our test DDF thread on the same LPAR looks similar, but with DDFTEST.) DDFPROD is defined as 1 period, Imp = 2, 90% within 2 secs. DDFTEST is defined as 2 periods, 1st Period Duration=1, Imp = 3, 90% within 2 secs 2nd Period Imp = 5, Execution Velocity of 50 Using PM and RMF panals, I found my user's thread running with DDFPROD priority.
