I am getting *** Metrics "Global Cache Average CR Get Time" is at *** kind of alerts from grid control from my RAC prod DB.
Can anybody tell me what should i do for these critical alerts? or will these effect on my applications performance which are running in my DB.
This metric refers to the average time necessary to get blocks from the Global cache.
This itself does nog mean anything.
Are you applications running on this DB experiencing performance issues?
If not, you might consider:
increasing the hresholds for this specific metric (use Monitoring Templates for this)
disable this metric (nullify the thresholds)
