RDBPROD blocks per transaction (BPT)

Hello,
Oracle Rdb Guide to Database Maintenance
Section 9.4.3 Setting the Allocation Size

To determine an appropriate allocation setting, estimate the amount of data that is written to the after-image journal file in one day.

Use the RMU Show Statistics command to establish an approximation for blocks per transaction (BPT) and transactions per second (TPS).


From screen "Snapshot Statistics", I estimate TPS = ("Total transactions" - "R/O transactions") / "Elapsed". Correct?

Need your help to estimate BPT

Thanks in advance,
Richard
