Error description

  • A Tivoli Storage Manager server halt command can take a long
    
    time to complete, when running runstats on a large table, and
    can use a lot of cpu and will appear to be
    hung.
    
    Customer/L2 Diagnostics:
    
    Forcing a core on the dsmserv process and analysing the crash
    file, one can see from the stack trace that
    a hang will be observed at halt due to a long running runstats
    operation.
    In addition, you should see a thread in RdbMonitorStatsThread
    that initiated both the reorg and the runstats:
    
    #10 0x00002aaaabb0d213 in db2Runstats ()
       from /tiam/IBM_IA_SSAM1/tsm/sqllib/lib64/libdb2.so.1
    #11 0x000000000072709a in RdbRunstatOneTable (
        db2TableName=0x2aaab2470e38 "Archive.Objects",
    myConnP=0x168e1e8,
        commit=True) at tbtbl.c:12080
    #12 0x000000000072865c in RdbReorgRunstatOneTable
    (tInfoP=0x2aaab2470e28,
        myConnP=0x168e1e8) at tbtbl.c:11747

Local fix

  • Allow more time for halt to complete
    
    or
    
    Use the option
    RUNSTATSCHKINTERVAL <interval_between_checks_in_mins>
    in dsmserv.opt to increase the interval between runstats
    to lessen the chance of runstats running at time of halt.
    The value is in minutes, and can be between 10 and 1440
    (the default is 10).
    
    or
    
    Add the following line to the
    dsmserv.opt file to turn off REORG of the db2 database:
    ALLOWREORGTABLE NO
