    COMMENTS:
    BJ10 callso TO2_recoupCollection to get a list of file
    addresses for a given collection for recoup to process.
    TO2_recoupCollection will only lock the collection if it is of
    a certain size. For larger collections, because they are not
    locked while recoup is processing them, there is a window in
    between when recoup begins to process these file addresses
    where the collection can be deleted. If this occurs and the
    datastore is DELETE-immediate,TPF Collection Support may
    release those records and file them down to the database with a
    different record ID. This will cause recoup to report errors
    for those file addresses.
    

Problem conclusion

  • SOLUTION:
    TPF Collection support delete processing in module CJ00 has
    been changed to query the structure object recoup indicator
    attribute to see if the collection is currently being processed
    by recoup without a lock. If this is the case and recoup is
    currently active, delete processing for that collection will be
    deferred until recoup is finished with that collection.
