OraSRP 4.1.0

First time I've read about LOBREAD lines in 10046 traces in Vladimir Begun's blog-post dated Jun 2, 2010. I've tried to reproduce such trace in my environment but failed. Since Vladimir is Oracle employee, I've decided that his example was from some yet-unreleased version of database.

...And I successfully forgot to re-check it even when 11.2.0.2 was released.

But recent Tanel's post reminded me about these LOBREAD lines.

So I've added processing of LOBREAD (and LOBAPPEND, LOBARRREAD, LOBARRTMPFRE, LOBARRWRITE etc.) calls in new version of OraSRP. Such calls displayed as 'LOB% calls' event. Remember, this works only for 11.2.0.2 traces - in earlier versions of database server such LOB% calls, I believe, are not instrumented.

As for another new feature of OraSRP 4.1.0, I'd like to inform that new version contains new section - Objects Statistics (per session and per statement). Here's what it looks like (long lines stripped for better readability):
