APAR status

  • Closed as program error.

Error description

  • "db2" front end process does an unnecessary internal
    initialization, (which is required for Db2 server).
    It might cause a performance degradation.
    

Local fix

  • Reducing the number of invocations of "db2" front end process
    might be able to mitigate the performance degradation.
    
    e.g.
    If a script like test.sh is executed, please consider to run
    "db2 -tvf test.sql" instead of test.sh .
    test.sh:
    db2 "sql1"
    db2 "sql2"
    ...
    db2 "sqln"
    
    test.sql:
    sql1;
    sql2;
    ...
    sqln;
