Thanks for this useful blog. We’re considering using STATSPACK instead of AWR.
In 11gR2 ‘shared server idle wait event’ is already included in STATS$IDLE_EVENT.

Can’t say I’ve actually tried moving statspack data from 9 to 11. That is a pretty odd behavior. You might want to open an SR to see if they know about that and there is a simple fix. I can’t imagine why it would move some but not all the statspack data. Thanks for the information.

Kerry,
Just wanted to let you know that I upgraded my databases from 9.2.0.6 to 11.2.0.1 last year and used perfstat to collect performance data. I spend a great deal of time on Perfstat and on upgrading it after the database was upgraded to 11gR2. The upgrade path was 9.2.0.6->9.2.08->11.2.0.1. I collected performance data at both 9.2.0.6 and 9.2.0.8 and also exported the perfstat schema before the upgrade to 9.2.0.8 and 11.2.0.1. I captured performance data with snap_level=>6 since I was most worried about execution plans changing(change from RBO to CBO). Anyway, after upgarding the statspack and importing it to 11.2.0.1 for comparison, I found that the statspack after importing, for some reason, was at level=>5 and thus lost all the execution plans. I was lucky this was test databases and then decided to use Stored Outlines to capture the execution plans and I was able to migrate these easily.

Yes it still works in 11.2.

Hi,
I am upgrading from 9i to 11gR2 and am working on collecting snapshots with statspack. My question is if statspack is still there in 11gR2?

Thanks Osborne

This saved me time. I was going around and asking what can I use after the 11g upgrade to look at a performance issue, for free! Your post is re-assuring and pointing people to the right way, rather than blindly AWR, is nice to know there is a powerfull, free alternative.

Very useful!

John,

Glad to hear the post was useful. I have to admit that when I saw your comment I couldn’t remember having ever mentioned that wait event. One of the best things about blogging (as far as I’m concerned) is that it gives me a place to keep a record of “stuff” that I’ve worked on and that it is easily searchable.

Thanks for the comment.

Hi Kerry,

Just a quick note to thank you for this post. The “shared server idle wait” event in the Statspack reports on my recently-upgraded db were threatening to make me pull out what little hair I have left. ;-)

Regards,

John P.
