Understanding the V$LibraryCache
Hi,
Can somebody help me to check if I'm understanding the V$LibraryCache Correctly or not.
Parse Phase
Gets No of time any Object was requested
GetHits No. of time the parsed information
of the requested Object was found
cached in Library
Execution Phase
Pins No. of times the requested Object
was Executed successfully
PinHits No. of times the requested Object
which was found parsed in Library
was Executed
Order of the above columns w.r.t Value will be:
Maximum in Gets
Then in Pins
Then in GetHits
Then in PinHits
GetHitRatio = GetHits/Gets
Should be near to 1 so that for a
Object Request most of the time
Parsed Information of the Object
is found in Library
PinHitRatio = GetHits/Pins
Should be Near to 1 so that Object
Excutions are mostly done using
the Parsed information in Library
GetHitRatio will always be greater than PinHitRatio
