A session waits on this event when requesting a mutex for sharable operations related to pins (such as executing a cursor), but the mutex cannot be granted because it is being held exclusively by another session (which is most likely parsing the cursor). This is a replacement for library cache pin waits in prior versions of Oracle. Solutions Solutions for mutex wait problems are very similar to each other.
See Analysis of Waits on Mutexes for more information and troubleshooting ideas.
