PI08666: INVALID COMMIT MODE AND SYNC FLAGS IN CEX X'3E' EVENT RECORDS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This APAR addresses these issues:
  1. The commit mode flags CERE_3E_SVT_SYNCFLAG in the 3E message
     exit returned from read contain invalid commit mode and sync
     flags for a Resume TPIPE request.         type3E RTPIPE
  2. There is a significant performance issue in the routine that
     checks ACEE cache entries for deletion by aging time.  This
     is especially noticeable when there are a large number of
     ACEE cache elements. There is no way for the user to specify
     the size of the ACEE cache.
  3. It is not possible to enforce that all inbound messages are
     processed by Rules Based Routing (RBR).
  4. The Definition Take-up utility SET OPTION has no effect, and
     the default behavior was incorrectly set to WARNING=IGNORE.
  5. Field CERE_3E_SVT_SOCKFLAG is missing flag bits that have
     been added by IMS Connect.

  The following issues are being addressed in this APAR:
  1. The commit mode flags (CERE_3E_SVT_SYNCFLAG) in the x'3E'
  message exit returned from read contain invalid commit mode
  and sync flags for a Resume TPIPE request.
  2. There is a significant performance issue in the routine that
  checks ACEE cache entry for deletion by aging time.
  This is especially noticeable when here is a large number of
  ACEE cache elements. There is no way for the customer to
  specify the size of the ACEE cache.
  3. It is not possible to enforce that all inbound messages are
  processed by Rules Based Routing (RBR).
  4. The Definition Take-up utility SET OPTION has no effect, and
  the default behavior was incorrectly set to WARNING=IGNORE.
  5. Field CERE_3E_SVT_SOCKFLAG is missing flag bits that have
  been added by IMS Connect.
  

Problem conclusion

• The following changes have been made for the above issues:
  1. The commit mode flags shown event are not used for Resume
  TPIPE as it is always Commit mode 0 synclevel confirm.
  The OTMA state header built by the message exit for a Resume
  TPIPE is not long enough to contain the commit and synclevel
  flags that are being mapped into the SYNCFLAG field. This has
  been changed to not attempt to collect commit mode and
  synclevel flags for a Resume TPIPE.
  2. The ACEE cache routines have been changed to add a new ACEE
  Cache element index so that the aging routine can search the
  ACEE cache elements by creation time when it is checking for
  ACEE cache elements that need to be deleted by age.
  A new SECURITY command has been added to the CEXCTLIN dataset
  that enables the customer to specify the size of the ACEE in
  terms of the maximum number of active Userid's in the ACEE
  cache.
  3. Default RBR rules are defined using two new options on the
  CEXROUTE CEXCTLIN command. If the datastore or alias in the
  the inbound message is not matched to an RBR rule, the
  appropriate default RBR rule is used.
  4. The Definition Take-up utility has been updated to process
  the SET OPTION correctly. The default is now WARNING=ABORT.
  5. Added the missing flag bits to event record macro CEXCR62.
