Re: [PHP-DB] Losing the ability to connect to Oracle database
Turns out that it's covered in bug report 30808. I've applied the edit mentioned there and will see if this solves my problem (have to wait for the next Oracle restart overnight). The discussion there is quite revealing about the fact that oci8 connections are always persistent even if you do not ask for a persistent connect of explicitly call for a disconnect. Seems to me that ought to be stated in the oci8 documentation. Christopher Jones wrote: Leo D. Geoffrion wrote: I recently upgraded to PHP5 and now have a curious Oracle problem.

Re: [PHP-DB] Losing the ability to connect to Oracle database
Hi Leo, We are having the same problem. Check out the bug I filed many months ago http://bugs.php.net/bug.php?id=30808 I can't for the life of me figure out why the bug is suspended, as this seems to be a common issue with Oracle and php5. Perhaps you should also and your comments to the bug report. To "resolve" the issue, we do an apache restart every time the db goes down. This flushes whatever connections php pools to Oracle (sounds weird considering we are doing oci8nlogon). I really hope that the OCI8 library gets some serious attention soon. In my mind this is a show stopper, and it appears that there are a few other big ones lying around... Michael -Original Message- From: Leo D.

RE: [PHP-DB] Losing the ability to connect to Oracle database
Leo, Please let me know how that works for you. I don't remember the specifics (if we where testing using plogon, nlogon or just logon), but we did try and implement that fix and it didn't work for us.

Re: [PHP-DB] Losing the ability to connect to Oracle database
It worked! I did not need to restart apache this morning in order to get an oracle connection. Michael Caplan wrote: Leo, Please let me know how that works for you.
