I am having a problem on 11.1.0.7 and Exadata v1 on Linux 64bit on hp.
10-node RAC database. The issue is with parallel queries going very slow. I saw the same sort of thing happen with two other clients. An Oracle technician in-house says that 11.1.0.7 was short-lived and the only reason it is still around is because of Exadata v1 and the issues it is having.
Is there something that Oracle does not publish that makes 11.1.0.7 very notorious for query slowdowns on Linus RAC databases? Do you know anything about the version and why many clients have the same issues with having parallel query slowdown issues? And having to flush the shared pool on every node nightly to alleviate slowdown?
Bug? Does 11gR2 resolve this?
Please help if you can

hi,
I have a critical performance problem.
i have a outer join query involving about 10 tables,and recordsa are more than 100 millions. We have a performance issue.Th query takes about 1 minute to fetch (result set is 7 million recs) the records. We need to tune that. We proposed to use a materialiaze view which was fast ( since it will have the result set) but that was not accepted because of we may have about 800 users working concurrently and the updates will kill the performance.
Pls suggest any alternative methods by which i can work on the result set of the query.

regards
Ganesh

@Ian Murphy Hi Ian, Yeah, I also think that I had enough material for 2 hours at least. I did only one demo, planned to do more. I think I'll do an online follow-up event :)

Hi Tanel,

Just wanted to say thanks for your talk at the UKOUG Exadata event yesterday. Was excellent and was just disappointed that you only had an hour!

Cheers,

Ian
