Transaction Tracking Parameters for the Traditional File System
 A transaction is a set of write operations that must be completed together
to maintain file and database integrity.
 Write operations consist not only of data and data records, but also of
changes to the index and the key structures that are important to an
application’s continual operation.
 Transaction Tracking System
TM
(TTS
TM
) software guarantees that a
transaction is written to disk in its complete form or is backed out if
incomplete. This ensures database integrity in case a failure occurs before
a transaction is completed.
For a description of transaction tracking parameters for the Traditional File
System, see the following table.
