I was referring :

For v$librarycache :
GETS NUMBER Number of times a lock was requested for objects of this namespace
GETHITS NUMBER Number of times an object's handle was found in memory
Q. Can someone differentiate what this two mean ?
Is it like GETS is the request made for the object and if its in the librarycache then its a incremental counter for GETHITS.
While if its not there then GETS would be a hard-parse
Also I believe that PINS is different from the above two.
Q. When would a GETS be there but not a PINS ?
