Hello List,

As We all know that The latch:library cache pin and latch:library cache lock
has gone in 11g?

But Oracle still use  library cache lock/pin to protect non-cursor object
,something like procedure or function.

So I have a question,    How does oracle allocate library cache pin/lock
structure without    "Latch:library cache lock/pin allocation"?

Any answer will be appreciated .
