how to tune gc cr block 2-way and gc current grant 2-way

Samuel RabiniMar 30 2012 — edited Mar 30 2012

Hi,

I'm working on an Oracle Database 11g Release 11.1.0.6.0 - 64bit Production With the Real Application Clusters option, Standard Edition.

During last days I'm suffering performance lack due to 2 main wait event classes:

gc cr block 2-way
gc current grant 2-way

I noticed also this one:
gc buffer busy acquire

Do you have any suggestion on how to check and tune my RAC to reduce those wait events?
Any usefull link?

Thanks in advance,
Samuel
