Oracle 220.127.116.11, 2-node RAC
We recently upgraded to 18.104.22.168 and began experiencing some performance
issues. We have addressed most of them. While reviewing the GRID
alert.log, I noticed errors on shmmax. the setting is different on the two
nodes. Node B has a setting twice as high as node A. Node A has a setting
above the minimum required, so we're good on that score. I've been
searching MOS and googling, but haven't found anything to address this
specific situation yet.
Questions: Is this really hurting us? Could it be causing some
performance degradation? We plan to set them the same, but is it something
we need to do sooner rather than later?
Thank you in advance for any guidance you can provide.
