I am running normal Oracle 8 with the web application server on a Sun
Enterprise 3500 box.
I keep getting "maximum open cursors exceeded", have the limit set at
500, and think that the problem is in my applications. So, I am going
to ask a few basic questions in hopes that I can fix this. Your help
would be much obliged?
- What is the cursor lifetime in the context of a PL/SQL web
application server cartridge? I take that if I have a package, and it
gets called by the web server, cursors not explicitly closed by that
package remain open forever and ever. Is this is true? What about
implicit cursors?
- What sort of cursor caching behavior does web application server
do? Is it possible to have a configuration where the number of cursors
managed by the web pl/sql cartridge exceeds the actual database limit?
If so, how does one fix?
- Part of our system includes a normal OCI program. Let's assume for
a moment that it is buggy and exits and disconnects without closing a
couple of cursors. Do cursors close on disconnect?
- Off the wall. What's the easiest way to get a persistent
connection for a C++ CGI that uses OCI?
- Back to topic. Is there a programatic way to determine which
cursors have been left open by a particular application. I was
thinking having some sort of a query against V$OPEN_CURSOR, but
evidently that table does not have every cursor in it.
Your help is greatly appreciated.
Thanks!
