DB2 for z/OS users are running out of virtual storage in the DBM1 address space, in many cases causing DB2 to fail. The usual reason is over specification of threads, simply because you didn't know WHAT to enter for DSNZPARM CTHREAD/MAXDBAT. Guess no more! For the price of a free download of John Campbell's MEMU2 package, you can answer the question: How many threads can this DB2 support? This presentation teaches you to analyze the output of MEMU2. Step by step instructions are provided for development of the spreadsheet and charts you will use. Real life samples the speaker has experienced in her analyses are also discussed. This presentation is for you, whether you are data sharing or not. if you are on DB2 V8 or 9.
