Lizette, I can answer some of your questions. If a DB2 Group Bufferpool structure is rebuilt it will go to the alternate CF from its preference list. However, the messages you listed do not include and DSN** messages. Is it possible that you are using z/OS CF duplexing? If so, I would recommend that you not use z/OS CF duplexing and instead let DB2 do its own Structure duplexing. This looks like this in the policy.
STRUCTURE NAME(DSNDBA0_GBP8) INITSIZE(6144) SIZE(11264) ALLOWAUTOALT(YES) FULLTHRESHOLD ( 70 ) REBUILDPERCENT(1) DUPLEX ( ALLOWED ) PREFLIST(CF4LP1,CF2) ENFORCEORDER(YES) If I am mistaken and you are using DB2 duplexing and not z/OS then my apologies. Mark Ediger >>>>>>>>>>>>>> text edited <<<<<<<<<<<<<<<<<<, Subject: How Structure REBUILD Really Works List - I have been working with the manuals last night, but am not getting a really clear picture on structure rebuild and preference list with duplexing in the CF. I have a DB2 group buffer pool whose preference list is STRA, STRB. Group owning node name XB0P, Members: XB1P and XB2P. At some point I an IXL/IXC messages indicating a rebuild process has been initiated. My question: Do DB2 GBP structures start out in one CF and sometimes wind up in a different CF if there is duplexing? If there is a rebuild process can it change which CF is preferred? *************************************************************************** The information contained in this communication is confidential, is intended only for the use of the recipient named above, and may be legally privileged.
