AST Enterprise Systems Management, a division of the AST Group, has introduced BMC Software`s Recover Plus for DB2 version 3.1. This new product comes with three new features that enhance the speed and flexibility of database recovery, providing maximum availability to the DBA faced with the need to recover crucial data following a failure.
One of the most remarkable features of this release is Backout Recovery, a new feature that provides users with an exclusive new way to recover to a point in time, significantly accelerating database recoveries by up to 23 times faster than the native utilities. Users recover to a point in time by starting with the database in its current state and backing out updates using the DB2 log.
"This feature is very useful in cases of application error, where the physical table spaces and indexes are undamaged, but the data they contain is incorrect," says Alan Kuun, Product Manager of AST ESM. "The advantage of this approach when the majority of the data is unaffected by the error is the great increase in efficiency."
Another feature of Recover Plus is Index Recovery, which allows users to recover their database indexes from image copies made during backup, resulting in faster recovery. This feature is compatible with DB3 versions 4.1 and 5.1 and offers advanced I/O techniques and superior sorting technology making index recovery options faster and more flexible.
In addition, Recover Plus for DB2 and its companion product, Copy Plus, provide full support for copying and recovering large indexes by the more manageable pieces defined by the user, rather than recovering these large objects in their entirety. This allows for more job concurrency and isolation of recovery for media failures confined to certain volumes.
