How to go about Mutex waits

Hi

Hi

Most of the times we see this waits due to cursor sharing issues

"cursor: pin S wait on X" ""Cursor: Pin X" Waits"

We check the version counts to address the issues with this waits.

Questions
1)
If we are not seeing the version counts in awr during this wait events

What other pointers we need to look from awr ( database) or from OS point of view

2)
How to confirm whether this waits are real or dummy waits

Thx in Advance 

Howdy, Stranger!
