PH45668: ABEND0C4 IN IGVCPDEL OR ABENDC78 IN EZASMI RESMGR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a task that had issued EZASMI calls ends without having
  done an EZASMI TYPE=TERMAPI, the EZASMI resource manager is
  invoked and calls program EZBSORM2 to clean up the EZASMI
  resources.  This processing includes deleting the EZBSOH03
  AUTODATA cell pool and releasing the EZBSOH03 AUTODATA storage.
  Sometimes these structures get released by customization exits
  before EZBSORM2 is called (this is particularly common in IMS
  environments).  If the cell pool has already been deleted, then
  the CPOOL DELETE might result in a S0C4 ABEND in IGVCPDEL.  If
  the AUTODATA storage has already been released. then the STORAGE
  RELEASE might result in a SC78 ABEND.  If the task is ending due
  to previous ABENDs, then the TCPIP stack might leave the SYSPLEX
  after message EZZ4215I.

  KNOWN IMPACT:
  Dump taken.
  TCPIP leaves the SYSPLEX.

Local fix

• BYPASS/CIRCUMVENTION:
  If possible, add a recovery routine to the application that does
  an EZASMI TYPE=TERMAPI.
  
  RECOVERY ACTION:
  Use the "VARY TCPIP,,SYSPLEX,JOINGROUP" command to rejoin the
  SYSPLEX.

Problem conclusion

• EZASMI resource manager program EZBSORM2 has been updated with a
  recovery exit to allow normal processing to continue if the
  delete of the AUTODATA cell pool or the release of the AUTODATA
  storage fails.
