Home -> Community -> Mailing Lists -> Oracle-L -> Re: How to map a client program to a Resource Manager consumer group
Hi Tony,
I have attached a sample script in a separate email. The script creates a plan and consumer groups.
One of the sites I am working on has had limited success with RM. There have been a couple of times it has bailed us out but on more than one occassion we have had sessions stuck in resmgr: cpu quantum even when the CPU on the box is at 50% idle.
I spent a day with the RM development team in San Fran last month identifying issues in the product. Unfortunately most of these I believe are unpublished.
The feature in RM to throttle sessions works fine. There are times when RM does not kick in even when load is nearing 100% Also RM also does not function properly on machines with more than 8 cpus.
Thanks
Fairlie

That's not encouraging. I did do some digging on Metalink and Google, but the only bugs I was able to find related to problems with mapping priorities. Can you give me an idea of the bugs that you found? Are they so bad that you would not use RM in a production environment at all? What do other people think about this?
Cheers,
Tony
