Problem summary

• ****************************************************************
  * USERS AFFECTED: All Distributed Data Facility (DDF) users.   *
  *                 Specifically those where DB2 is accessed     *
  *                 (as a server) via TCP/IP connections from    *
  *                 remote CICS or IMS based DB2 for z/OS        *
  *                 applications.                                *
  ****************************************************************
  * PROBLEM DESCRIPTION: Unrealistic SMF 101 record elapsed      *
  *                      times due to incorrect QWAC related     *
  *                      values, such as QWACBSC, QWACBJST,      *
  *                      and QWACASC.                            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When a DB2 for z/OS server thread is reused, on behalf of a new
  user of a remote CICS or IMS based DB2 for z/OS application,
  accounting processing is necessary to reflect the end of
  activity related to the prior user and the beginning of
  activity related to the new user. When the connection to the
  DB2 for z/OS server is via TCP/IP, this accounting transition
  may not occur which may ultimately lead to incorrect QWAC
  accounting values.
  

Problem conclusion

• DB2 (DDF processing) has been changed to ensure that proper
  accounting transitioning will occur.
