Error description

  • Tivoli Storage Manager Server 6.3 enables the DB2 INTRA_PARALLEL
    configuration parameter. This leads to performance decrease,
    addressed in APAR IC82940.
    But this APAR does not reset the INTRA_PARALLEL configuration
    parameter to the previous default value, automatically.
    This leads to performance decrease also on Tivoli Storage
    Manager 6.3.2
    and higher servers containing the fix for APAR IC82940 when they
    were
    updated from server 6.3.0.x or 6.3.1.x.
    
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager server: 6.3.2 and higher, all plattforms
    
    Initial Impact:
    Low

Local fix

  • Halt the Tivoli Storage Manager server and run the following
    commands
    from the DB2 commandline:
    db2 attach to <TSM server instance>
    db2 update dbm cfg using INTRA_PARALLEL NO
    db2 terminate
