COMMIT_POINT_STRENGTH is relevant only in distributed database systems. It specifies a value that determines the commit point site in a distributed transaction. The node in the transaction with the highest value for
COMMIT_POINT_STRENGTH will be the commit point site.
The commit point site of a database should reflect the amount of critical shared data in the database. For example, a database on a mainframe computer typically shares more data among users than one on a personal computer. Therefore,
COMMIT_POINT_STRENGTH should be set to a higher value for the mainframe computer.
The commit point site stores information about the status of transactions. Other computers in a distributed transaction require this information during Oracle's two-phase commit, so it is desirable to have machines that are always available as commit point sites. Therefore, set
COMMIT_POINT_STRENGTH to a higher value on your more available machines.
