    What does Global Headings Change (Catjobs 11,12 and 13) do?


    These three jobs provide you an opportunity to configure, check and preview the proposed changes.  Run them one at a time, and wait for the preceding job to successfully complete and review the results before starting the next job.

    Catjob 11 looks at the headings structure of the database and determines how many headings potentially could be affected by the change in question.

    • Voyager counts bibliographic records that exactly match the heading that has been changed.
    • For all the heading types except subdivision headings, the bibliographic records that are counted are only those that match exactly.
    • Bibliographic records are not counted if they contain the heading followed by further subdivisions.

    Catjob 12 finds the specific bibliographic and authority records that will be affected by the change.

    • The change to the heading in the records can be viewed in the GHC queue Preview window.
    • Catjob 12 also clears headings that will not affect any bibliographic or authority records from the queue.
    • Sometimes a change will enter the queue but will not change any records.
    • Example: a name heading is part of a name/title combination in every record in which it appears. It is part of the Name Headings index, and is added to the queue as a Name heading. But because it's part of a name/title heading in other records, it can only be changed as a name/title headings change.
    • Catjob 12 also does not queue records that have been modified since the date the heading was added to the GHC queue. This protects manual changes from being overwritten by Global Headings Change.

    Catjob 13 executes the headings change in the bibliographic and authority records.

    • Any headings remaining in the queue after catjob 13 will be cleared the next time catjob 11 is run.
    • Catjob 13 won't change a record if the record has been manually updated since the heading was added to the queue.
