Record Formats
UPDATE (10)
This record signifies the modification of an existing record in an audited file. An update
record can occur in either the master audit trail or an auxiliary audit trail.
Note that when audit compression is enabled, update records are not generated;
instead, the disk process generates update autocomp records for Enscribe data files
and update fieldcomp records for NonStop SQL/MP files.
Variable-length fields: before-image and after-image
UPDATE AUDITCOMP (11)
This record reflects updates to an Enscribe file when audit compression is enabled.
The major difference between this record and an update record is that the before-
image and after-image within an update auditcomp record are encoded. Call
ARFETCHFRAGMENT to get the offset, length, before-image, and after-image of each
data record fragment. The recordkey field identifies the modified record.
Variable-length fields: recordkey and fragments
