Bug #12518 Updated: ocifreestatment doesn't free the Oracle cursor and so you run out of cursors

ID: 12518 User updated by: derek@innovyx.com Reported By: derek@innovyx.com Old Status: Feedback Status: Open Bug Type: OCI8 related Operating System: Linux PHP Version: 4.0.6 New Comment: I have a long-running PHP script that eventually comes up with: Failed execution, error: ORA-00604: error occurred at recursive SQL level 2 ORA-01000: maximum open cursors exceeded. I don't explicitly use any cursors in this script btw. In addition I found (via a web search) that someone else has been experiencing the same thing. However, in response to your request I've been trying to build a test script to leak cursors and reproduce the problem, unfortunately, thus far, even deliberately leaking cursors is not producing it. :( Previous Comments: ------------------------------------------------------------------------ [2001-08-01 16:18:03] thies@php.net what makes you belive it doesn't work? please send me a short testcase that shows leakage of resources. ------------------------------------------------------------------------ [2001-08-01 13:20:01] derek@innovyx.com the ocifreestatment function doesn't actually free the Oracle cursor, these are only freed when the script exits. While this isn't a problem when using PHP as a web page it is a problem if you have a command line script that has to perform thousands (or tens of thousands) of queries eventually the open_cursors limit is exceeded and all further queries fail. The same appears to be true with connections. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12518&edit=1
