C.9.10. Oracle::Library Cache

Library Cache Miss Ratio — The rate at which a library cache pin miss occurs. This happens when a session executes a statement that it has already parsed but finds that the statement is no longer in the shared pool.

Executions — The number of times a pin was requested for objects of this namespace.

Cache Misses — The number of pins of objects with previous pins since the object handle was created that must now retrieve the object from disk.
