IBM Tivoli Storage Manager V6.3 Fix Pack 6 (6.3.6.000) Server Downloads
APAR status
Closed as program error.
Error description
The Tivoli Storage Manager server "generate backupset" process performs poorly when DB2 uses a different index as intended. This happens though the REORG status of the tables/indexes are fine and the RUNSTATS data are current. This leads to unnecessary index reads slowing down the "generate backupset" processing, e.g. a backupset generation which takes in common two days, take weeks to complete. Customer/L2 Diagnostics (If Applicable): The instrumentation trace may show a high value in the "DB2 MFtch Exec" section for the ProcessNodesThread: Thread 4158482 ProcessNodesThread ...
