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.
