Error description

  • During heavy workload, for instance when several hundred Tivoli
    Storage Manager client sessions are active at once, a Tivoli
    Storage Manager 6.1/6.2 server may fail to open new
    database connections causing eventually the server to stop
    working.
    
    
    Customer/L2 Diagnostics:
    Following message can be seen in the ACTLOG:
    <date> <time> ANR9999D_0015032189 FindPoolToUse(dbiconn.c:1127)
    Thread<xx>: Pool count error: DBV->lastPool 3;
    MAX_NUM_CONNECTION_POOLS 10, DBV->poolCount 3
    
    with DBV->lastPool being the same as DBV->poolCount.  This puts
    the server into a state where no database connections can be
    started, and so it eventually stops doing any additional work.
    This usually occurs when the server has a heavy workload.
    
    
    Tivoli Storage Manager Versions Affected:
    All Tivoli Storage Manager 6.1 and 6.2 servers
    
    
    Initial Impact:
