Charlie,

What is the perceived relevance of gaining this information? You would be much better off correlating statistics such as overall non idle wait time and database workload (# Users, Ion's/CPU etc...) to actual business functions the database is performing (invoices, sales orders, etc...). I could easily go write a job that doubles the total number of transactions per minute but has almost no effect on the other items which actually correlate application performance to database performance.

Thanks,
Ethan

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?
