Library cache lock & Library cache: Mutex x

KeenOnOracleJul 29 2016 — edited Aug 2 2016

Hi Friends,

We are running 11.2.0.3.0 and getting a pretty high number of Library cache lock & Library cache: Mutex x

We already used DBMS_SHARED_POOL.MARKHOT to mark the object being select as a HOT and even put this table in memory using KEEP pool.

But Library cache lock & Library cache: Mutex x still too high, causing a performance bottleneck

Any other suggestions for this 2 wait events?

Tks a lot
