Problem summary

  • ****************************************************************
* USERS AFFECTED: All DB2 10 and DB2 11 for z/OS users who     *
*                 use IBM DB2 Analytics Accelerator.           *
****************************************************************
* PROBLEM DESCRIPTION: -STOP ACCEL command hangs when there    *
*                      is no thread off-loaded to the remote   *
*                      Accelerator.                            *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
DB2 registered a thread that was intended to off-load to the
remote Accelerator.  However, in certain cases, this thread may
not off-load after all and deregistration may be delayed if the
thread continues servicing other work.  This will result in a
hang of -STOP ACCEL command processing.

Problem conclusion

  • DB2 has been changed to register accelerator interest only
when actually necessary.

Temporary fix
