RE: 11i Conc. Manager Question

Mike/Tim

My suggestion was based on 10.7 and database version 7.3.4 on HP-UX 10.20. Yes, I am also pinning a lot of objects of Oracle Financials to avoid shared pool congestion. Increasing shared pool was not an option at that time due lack of available memory, flushing shared pool was the only option available. Now after having more memory(2 to 4GB) increasing size of SGA , moving to 64BIT machine/HP-UX 11 64 bit,(same oracle version 7.3.4) and faster drives, this problem resolved.

As regard specific question of Tim, when I was starting my work around 9AM and checking active users there were 4/5 active users but just after flushing shared pool active users were jumping from 4/5 to 28/30 users and all pending requests in concurrent managers were finishing very fast...and users were also getting faster connections...

As we have more memory and increased SGA size now , I cannot produce same results otherwise I could have displayed this before and after flushing shared pool....

Tim/Rafiq,
I first saw problems with this on Apps 10.7. Lots of large packages simultaneously in use. I don't think that it affected speed so much as useability. There were constant complaints of forms not working when usually there just wasn't a big enough free fragment in the shared pool.
Flushing the pool allowed people to continue in the short term. I addressed this by pinning all of the frequently used code at startup time.

Please explain how the shared pool is involved and how flushing it will help?
