PH44946: ERROR IEW2456E DURING APPLY OF PTF UI78578 AND/OR UI79500 22/03/31 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• SMP/E APPLY of PTF UI78578 and/or UI79500 fails due to errors:
  IEW2322I 1220  70    NAME CSQ7CBF(R)                        MAX
  ACCEPTABLE RC=04
  IEW2456E 9207 SYMBOL CSQWRMFT UNRESOLVED.  MEMBER COULD NOT BE
  INCLUDED FROM THE DESIGNATED CALL LIBRARY.
  IEW2456E 9207 SYMBOL CSQWTAB UNRESOLVED.  MEMBER COULD NOT BE
  INCLUDED FROM THE DESIGNATED CALL LIBRARY.
  
  The problem here is that PTF UI78578 (and/or UI79500 which
  supersedes it) recompiled CSECT CSQ7VTBL after the change in
  UI77966 had been delivered to the LTS release.
  
  UI77966 added a new external entry point in CSQ7CBW, but
  UI78578 did not pre-req it. CSQ7VTBL has a reference to this
  entry point in CSQ7CBW, but since UI77966 was not applied, then
  the reference could not be resolved during the APPLY step.
  
  This is due to the way in which the dump formatter updates are
  shipped. We usually work around this by declaring the external
  references as 'weak external references' (WXTRN).
  Unfortunately, the logic to do this was not included in
  CSQ7VTBL.

  ****************************************************************
  Some MQ CSECTs have logic to declare certain entry points as
  weak external references (WXTRN). This allows for modular
  delivery of CSQWDPRD and CSQXDPRD dump formatter updates. The
  logic to do this was not included in CSQ7VTBL.
  

Problem conclusion

• CSQ7VTBL has been changed to declare some entry points as weak
  external references (WXTRN).
