Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of DB2 9 and 10 for z/OS who use   *
    *                 IBM DB2 Analytics Accelerator (IDAA).        *
    ****************************************************************
    * PROBLEM DESCRIPTION: IFCID 3 accounting records are not      *
    *                      written on transaction boundaries       *
    *                      for distributed DataBase Agent Threads  *
    *                      (DBATs) that service queries that are   *
    *                      offloaded to IDAA.                      *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A remote application connects to a DB2 for z/OS server and
    executes queries that qualify to be offloaded to IDAA.  Due to
    the IDAA involvement, the DBAT that services the query remains
    active.  As a result, DB2 accounting data is not available
    until the connection is terminated and hence the DBAT
    deallocates.
    For long running DBATs, this presents a usability issue as it
    is difficult to understand how the application is performing
    and behaving.
    

Problem conclusion

  • DB2 for z/OS has been changed to support transaction level
    accounting for distributed threads (DBATs) that service
    IDAA requests, regardless if the DBAT remains active.
