PK55716: RESYNC XID DATA INCORRECTLY SENT BY CICS TS 3.2 TO THE CICS TRANSACTION GATEWAY V 1.7 WHEN USING IPIC CONNECTIONS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Work that has been routed into a CICS TS 3.2 region from a CICS
  Transaction Gateway V7.1 over an IPIC connection may fail
  in-doubt and be shunted by the CICS region. Each work item will
  have an XID that uniquely identifies it. A Gateway can at any
  time request a list of XIDs that are associated with units of
  work that are shunted and in-doubt. When a gateway issues this
  request it receives back a list of XIDs that may also include
  ones associated with units of work that are still in-flight.

  ****************************************************************
  When CICS receives an XA recover request it browses the list of
  RM links of type ISJU, and returns the XID data found in each of
  them. The browse finds all such links in the system at that time
  and fails to distinguish between those whose units of work are
  in-doubt, and those that are not.

Problem conclusion

• DFHISRE has been changed to return only the XID data for those
  links that are in-doubt.
