Hi, list:

I noticed that one of our RAC ( shows 4 digits in ‘gc current block 
pin time’ of AWR.
Avg global cache current block pin time (ms): 2,717.7

Other than this, there was no other gc level stats >20 ms.

I searched this but I couldn’t find much information. What problem it is trying 
to tell me? Which direction I should look?
