ACBCHK keyword

Use the ACBCHK keyword to specify whether to check the ACB during the reload job.

For the UNLOAD command, this keyword specifies to write the DBD information in the USR files. For the RELOAD command, this keyword specifies to check the DBD information in the library that is specified on the IMSACB DD statement or in the IMS directory that is specified by the IMSCATHLQ keyword with the DBD information in the USR files.

ACBCHK is an optional keyword for the following commands:

  • RELOAD
  • UNLOAD

YES
  • When ACBCHK=YES is specified for the UNLOAD command, the unload process writes DBD information records into the USR files.
  • When ACBCHK=YES is specified for the RELOAD command, the reload process checks the consistency between the DBD information in the library that is specified on the IMSACB DD statement or in the IMS directory that is specified by the IMSCATHLQ keyword and the DBD information in the USR files that were created during the Unload process.
NO
  • When ACBCHK=NO is specified for the UNLOAD command, no DBD information record is written into the USR files.
  • When ACBCHK=NO is specified for the RELOAD command, the Reload process does not check the ACB.

Notes:
  • When both ACBCHK=YES and FORMAT=USER are specified for the UNLOAD command or the RELOAD command, ACBCHK=YES is ignored.
  • When ACBCHK=NO is specified or the ACBCHK keyword is not specified for the RELOAD command, and when the DBD information records are included in the USR file, the Reload process skips the DBD information records and continues processing.
