RE: Buffer gets increase in massive execution

Sounds like different explain plans between the two executions. Do you have different system stats for different periods (OLTP/batch) of the day? Are you changing optimizer_mode or any other parameters in your batch process? Do you have a smaller arraysize in your batch process?

Subject: Buffer gets increase in massive execution

Hi:

I have a batch process that executes individual transactions, normally a transaccion e.g. a simple select would take 8-10 buffer gets but in the batch processing it takes 45 buffer gets.

Any ideas in the explanation?

TIA
