RE: Newbie DBA question

Funny thing about questions like this is that there's no real way to map the answer to such a question back into something that you can actually use in the real world. The problem: what exactly is a transaction? The number you'll get by using statspack is derived this way: number(transactions) = number(commits). But, from the business perspective, what is a transaction? For a given business, it may range from a .2-second form validation to a 3-hour report! It makes no sense to talk about the characteristics of an "average transaction" on a system unless it has homogeneous workload-which is a situation that arises almost never in nature.

Bryan,  

You can run statspack snapshots every hour, then run reports comparing each hourly snapshot and it will show you the transactions/sec in the top "Load" section. No init setting required for this, but you'll want timed_statistics=true in order to gather other useful stats.  

Regards,

Brandon
