z/OS(r) Version 8 DBA Certification Guide: DB2 Environment By Susan Lawson Sample Chapter is provided courtesy of Prentice Hall PTR. Date: Jan 28, 2005. http://www.ibmpressbooks.com/articles/article.asp?p=360648&seqNum=2&rl=1 ------------------------------------------------------------------------ ---------------------------------------------------- To establish the z/OS address space dispatching priorities, the IRLM address space should be placed above IMS, CICS, and DB2, with DB2's MSTR and DBM1 address spaces placed above CICS. The following is a recommended priority listing: MVS monitor with IRLM capabilities IRLM DB2 performance monitors DBM1 MSTR WLM-managed application environments CICS If the IRLM address space is not at the top of the dispatching priorities, DB2 locks will not get set and released without causing excessive wait time ------------------------------------------------------------------------ ----------------------------------------------------- I am also being told this: "modifying the dispatching priorities is obsolete. WLM is taking care of that nowadays" This leaves me with a few questions I hope can be answered by Mr. John Someone who has been there and done that. 01. Does WLM automagically give the DB2 IRLM address space a higher dispatching priority that the other DB2 address spaces, or does this dispatching priority have to be specified correctly by a sysprog ? 02. Is SDSF lying to me when it displays equal dispatching priorities for the DB2 IRLM address space and the other DB2 address spaces ? 03. If WLM specifications are necessary for the DB2 address spaces what is the easiest way to check if they are correct ? 04. RTFM - i read well but have enough DB2 manuals to build a house, can u point to the best one regarding this topic for V8 ? T.I.A. (I.S.O.P.) ---------- This is not too difficult: 1. No, you must specify a Goal for it. It normally is / should be in Srvclass: SYSSTC. You WLM administrator can change the definitions in the WLM policy if appropriate. 2. No, don't suppose so. 3. In SDSF go to the column SrvClass and look for the IRLM Srvclass. 4. Sorry, I think you quoted all what is necessary.
