Hi, experts:
We have a RAC system, in AWR report "gc buffer busy" is top 1 wait (31
Percent Total DB Time), and "gc cr multi block request" is the 2nd (21
Percent Total DB Time)
But in AWR report - "Segment Statistics" section ,we can only find
there are lots of "Current Blocks Received", not so much "CR Blocks
Received".
So my question is: Is it possible If a session waiting on "gc cr multi
block request" and then it received a "Current Block"?
