This field displays the minimum number of committed transactions
the Log Rollforward Server (LRS) process on the standby database
will process in a single batch. Decreasing this value may cause
asynchronous pre-fetch stalls; increasing this value may cause
buffer turnover. The default is 10 transactions. You can override
the default value with the RDM$BIND_LRS_COMMIT_QUEUE_MIN logical
name.
