Bug #58925 [Asn->Csd]: No error information available when php_oci_create_env fails

Edit report at https://bugs.php.net/bug.php?id=58925&edit=1 ID: 58925 Updated by: sixd@php.net Reported by: glenn dot schmidt at deakin dot edu dot au Summary: No error information available when php_oci_create_env fails -Status: Assigned +Status: Closed Type: Bug Package: *General Issues Operating System: Any PHP Version: Irrelevant Assigned To: sixd Block user comment: N Private report: N New Comment: This bug has been fixed in SVN. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. For Windows: http://windows.php.net/snapshots/ Thank you for the report, and for helping us make PHP better. Code to print the Oracle error message has been added. It may help but from previous experience I know it's not feasible to expect Oracle libraries to identify the real root causes of misconfigured systems. So, if the root cause is some memory corruption from any subsystem involved, I wouldn't expect the messages to be reliable.

The root problem could be anywhere (including webserver memory corruption). However since the failure is coming from the environment setup, it's worth triple-checking the OCI8 environment is set correctly. Make sure scripts don't use setenv() to set Oracle environment variables. ------------------------------------------------------------------------ [2011-11-07 11:13:58] areddan at silverarm dot com Does anyone have a solution / update to this one ? I', experiencing similar issues on a clients site, and again its not repeatable. ------------------------------------------------------------------------ [2010-09-08 18:57:56] russ at iris dot washington dot edu I am seeing this error now for the last few months. Very frustrating because no way to force it to happen. As far as I know I changed nothing at all. There must be some resource limit either in PHP or Oracle that is not being reported back as being exceeded. The Apache logs (access and error) contain nothing. ------------------------------------------------------------------------ [2009-11-04 20:52:22] glenn dot schmidt at deakin dot edu dot au To force an OCIEnvNlsCreate failure you can always move or otherwise make inaccessible some of the instant client library files. But the particular issue I am seeing on our production web server (running Red Hat EL 5) involves OCIEnvNlsCreate failing intermittently, and unfortunately we can't reliably reproduce it. All we know is, when it starts to happen, it seems to globally affect all web applications on the host for a few minutes (none of them can connect), then it goes away again. I'm not saying that the oci8 extension is responsible for the problem we're seeing, but the fact that the error condition can't be trapped and identified by the PHP script (with oci_error()) is making it harder to track the problem and identify how frequently it's happening. A lot of applications (including Zend_Db) will suppress oci_connect() warnings with @ and then only log the output of oci_error(). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
