I'm trying to track down a SQL_ID which is *always* very prominent in the
Top Activity view of OEM 12c. When I attempt to drill down into the
specific statement, however, it always reports that "The SQL statement is
not available". I can see it listed in [g]v$session and ASH, and thereby
determine that it's executed very frequently and completes quickly, but for
some reason the beastie is never present in [g]v$sql or AWR. I've also
tried tracing some of the sessions which frequently show the SQL_ID in
question, but couldn't find it listed in any tracefiles either
It seems virtually identical to the issue Kerry Osborne blogged about in Hidden
SQL why cant I find my SQL
Text?<http://kerryosborne.oracle-guy.com/2009/04/hidden-sql-why-cant-i-find-my-sql-text/>,
with the very significant exception that the SQL_ID is never present in
[g]v$open_cursor either. Has anyone else encountered this situation? Any
suggestions on where else I can look, to hopefully figure out what the heck
it's doing? The database in question is Oracle Enterprise Edition
11.2.0.3.6 64-bit, running on a 3-node Solaris 10 SPARC cluster.
It isn't clear this activity is adversely affecting performance (the vast
majority of waits seem to be *SQL*Net break/reset to client*), so this
isn't an urgent issue. Mainly it's just annoying that I can't seem to
identify anything of significance about what's occurring... wounded pride,
and such. (-;
Thanx!
