Two questions about Commit BATCH

in Database Tuning (MOSC) 3 commentsAnswered ✓

Oracle document (https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/COMMIT.html#GUID-6CD5C9A7-54B9-4FA2-BA3C-D6B4492B9EE2) says:

The BATCH parameter causes the redo to be buffered to the redo log, along with other concurrently executing transactions. When sufficient redo information is collected, a disk write of the redo log is initiated. This behavior is called "group commit", as redo for multiple transactions is written to the log in a single I/O operation.


I have some questions:

1. About "sufficient redo information", how many transactions will be combined with a batch? Can it be configured?

Howdy, Stranger!
