This alarm uses the following file structure specific logic to examine and determine a file full condition:
Keyed-sequenced
All partitions are examined individually.
(data is placed in any partition as specified by the partition starting key)
Entry-sequenced
Relative
Unstructured
Only the last partition is examined.
Secondary partitions are skipped.
(partitions are extensions of the overall file so data is placed at the specified location (Unstructured, Relative) or appended to the end (Entry-Sequenced, Relative))
