PQ10184: ABEND 0C4 IN IFG0198N+X'3EE' WHEN STARTING THE IMS LISTENER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer gets ABEND 0C4 RC10 in TCP/IP 3.2 during startup of IMS
  listener BMP. The Abend occurs in module IFG0198N+x'3EE' which
  is at Level UW90275.
  The reason is, that the exit list pointed by DCB+24 (EZAIMSFX+
  2B6), is not a fullword boundary.
  If that is the case, then IFG0198N deletes the last 2 bits from
  that exit address and does wrong processing after that. The AND
  instruction for that action is at x 3b6 in IFG0198N.

  * RECOMMENDATION:                                              *
  ****************************************************************
  When the TCP/IP IMS Listener task is started and the DCB Open
  exits are invoked, unpredictable results can occur since the
  address list for the DCB exit routines is not aligned on a
  fullword boundary
  

Problem conclusion

• The TCP/IP IMS Listener subroutines have been amended to insure
  the DCB exit list is aligned on a fullword boundary.
