PH26632: OSC ENHANCEMENT TO ISSUE THE CHKCOMP COMMAND

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Currently, a loaded edit/compression exit routine cannot be
  refreshed to a new version by IMS online change when the
  edit/compression exit routine is being used by other databases.
  So, this APAR provides new function to issue the CHKCOMP command
  by using IMS Tools Online System Interface (TOSI) to check if
  the edit/compression routine is being used by other databases.
  The Online Structure Change utility will stop processing if
  the TOSI CHKCOMP command detects this condition.
  This enhancement will prevent a possible database corruption.
