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.
