PK28986: ABENDAXGA ON START CHANNEL SHIPPED TO REMOTE SYSTEM OVER MRO 06/09/28 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a START CHANNEL is shipped to a remote system over MRO,
  exception traces and AXGA abends occur in DFHAPCR IMPORT_ALL on
  the receiving system. The problem is that the overall length of
  the flattened channel in the TIOA is incorrect, and so DFHAPCR
  continues to loop looking fro additional data beyond the end of
  the TIOA.
  The reason is that on the sending side, the size of the
  container pool ( cpcb_pool_size) is incorrect -counting each
  container twice. This seems to be a consequence of the change
  made in APAR PK20794.

  ****************************************************************
  When an EXEC CICS START TRANSID() CHANNEL() command is issued
  for a remote SYSID, a container pool is built to ship the
  channel data to the remote system. DFHPGCP incorrectly doubles
  the length of the container pool, and an incorrect length
  channel is shipped. This results in an abend AXGA on the remote
  system.

Problem conclusion

  DFHPGCP has been changed to build the container pool with the
  correct length.
