Home -> Community -> Mailing Lists -> Oracle-L -> RE: library cache lock on import
Argh, that's what happens when cutting and pasting and cleaning things
up hastily!
libpin.sql should be fine.
liblock.sql, the line that reads:
and vsw.event = 'library cache pin'
SHOULD BE:
and vsw.event = 'library cache lock'
If no sessions are waiting on a library cache pin or library cache lock, respectively, then nothing will be output.
Sorry for the extended confusion. With the fix above, I believe both scripts to be (finally) correct.
