APAR status

  • Closed as program error.

Error description

  • If you use IBM DB2, a deadlock might occur during the DB2 index
    scan of the LSW_BPD_INSTANCE_VARIABLES table if the access path
    of the DB2 optimizer has become stale and must be refreshed by
    running RUNSTATS.
    

Local fix

  • Define the LSW_BPD_INSTANCE_VARIABLES table to be VOLATILE to
    reduce update performance and run RUNSTATS once a day.
    

Problem summary

  • No additional information is available.
    

Problem conclusion

  • A fix is available for IBM BPM V8.0.1.2  that reduces the
    probability of a deadlock by sorting the alias names of the
    business data so that DB2 always accesses the rows of this table
    in the same sequence. The fix also detects and handles the
    deadlock properly.
