RedoSegmentSize

The RedoSegmentSize attribute determines the size, in MB, of the segments used to divide the transaction log for parallel redo processing.

Each segment is independent, allowing the parallel redo transaction log cursor to read and process one segment at a time. You can specify the segment size using the RedoSegmentSize connection attribute, which sets the size of each segment in megabytes (MB). The transaction log is divided into segments irrespective of parallel redo is enabled or disabled (see EnableParallelRedo). The RedoSegmentSize value becomes effective once the database is up and running. If the database becomes invalid and you change the value of RedoSegmentSize, the new value will take effect after the recovery process is complete.

For details on how to configure this attribute, see Parallel Redo Recovery in TimesTen Database in the Oracle TimesTen In-Memory Database Operations Guide.
