RE: v$sql.parsing_user_id=0 when parser was not SYS

You can get owner schema and object name from v$object_dependency.

Join v$sql with v$object_dependency on v$sql.address = v$object_dependecy.from_address and v$sql.hash_value = v$object_dependency.from_hash

I guess "parsing_user_id=0" for non SYS schema issued sql statements has something to do with shared pool fragmentation.

Thanks,

Not sure about the parsing_user_id=0, but to answer your question about
the separate child cursors in v$sql:

No, there should not be a separate child cursor for each user, there
should only be separate child cursors if for some reason different
executions of the same query have different schemas, optimizer parameter
settings, etc. that make it impossible for them to share the same
cursor. Usually you can see the cause of the multiple child cursors in
v$sql_shared_cursor, but not always.

Brandon

Subject: v$sql.parsing_user_id=0 when parser was not SYS Looking at v$sql, I see that quite often a cursor that was actually
originally parsed by some user other than SYS shows a PARSING_USER_ID of
0 (SYS). How can I tell who really parsed this cursor? Shouldn't there
be a separate child cursor in v$sql for each user that uses the cursor?
