My reply would be something along the lines of
"A transaction as you would like it to be measured is best measured
in the application. I can provide you with IO per minute, broken down
into reads and writes, and a number of other statistics."
What they are asking for cannot be measured from database statistics,
as the oracle concept of a transaction is a unit of work terminated by
a COMMIT or ROLLBACK.
eg. SAP can provide the type of metrics they want via its BASIS
admin utilities.

To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> cc: Subject: measuring TPM |
I've been asked to provide value for the Transactions Per Minute
going through our primary OLTP production database.
I believe I can use deltas in SCN values to measure "transactions"
which do INSERT/UPDATE/DELETE and then COMMIT;
Is there any way to measure/count the number of SELECTs which occur?
If so, how?
How would you derive a value for TPM for your DB?
