The iSeries™ system
uses journaling and commitment control to help you recover data in a database
file.
Manage journals
Journal management allows you to record all the data changes that occur to one or more database files. You can then use the journal for recovery.
Ensure data integrity with commitment control
Commitment control lets you define and process a number of changes to database files in a single unit (transaction). It can ensure that complex application transactions are logically synchronized, even if the job or system ends. Two-phase commitment control ensures that committable resources, such as database files on multiple systems, remain synchronized.
