Please try OCI8 from PECL CVS.

I downloaded the latest oci8 module from PECL CVS,
and replaced the ext/oci8 directory that came with
php 5.1.1 with the CVS version.

When I run 'make', it fails with lots of "undefined symbol"
errors, eg:

ild: (undefined symbol) zif_oci_pconnect -- referenced in the data segment of ext/oci8/.libs/oci8.o
ild: (undefined symbol) zif_oci_connect -- referenced in the data segment of ext/oci8/.libs/oci8.o
ild: (undefined symbol) zif_oci_field_type -- referenced in the data segment of ext/oci8/.libs/oci8.o

Here's the configure line I used:

./configure --prefix=/usr/local/encap/php-5.1.1 --with-oci8=/oracle/product/9205 --with-xmlrpc --with-ldap --with-curl=/usr/local/encap/curl-7.14.1 --without-pdo-sqlite --with-apxs=/var/apache-test/sbin/apxs --enable-memory-limit

What do I do now?

Did you run ./buildconf --force after that?

Thanks, the buildconf helped somewhat.  Php builds properly now, and I can load the module into apache, but now our apache children are dying:

[Wed Dec  7 15:15:58 2005] [notice] child pid 29531 exit signal Segmentation Fault (11)
[Wed Dec  7 15:16:47 2005] [notice] child pid 29545 exit signal Segmentation Fault (11)
[Wed Dec  7 15:16:47 2005] [notice] child pid 29483 exit signal Segmentation Fault (11)

We are using apache 1.3.33 with php 5.1.1 on Solaris 9.

Same problem with PHP 5.0.4, SunOS 5.9, Oracle 9.2 and OCI8 Revision 1.257.2.6. Bug seems not be fixed in #29779.

Same problm under:
PHP Version 5.0.3
Linux 2.4.21-27 SMP

for now no solution found except apache restart

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.1-win32-latest.zip

This Snapshot solve the same problem we had with 5.1.2 on our 

IBM eServer PPC64 RHAS4upd2 with Oracle 10.2g for POWERLinux

I'm experiencing the same problem, but the latest snap didn't fix it.

5.1.3-dev (18/Jan/2006) contains OCI8 $Revision: 1.269.2.3 $

The scheme is the same as reported befire:

- Start Oracle (v9.2)
- Start Apache
- Everything ok
- Restart Oracle
- ORA-24327 Returned when trying to connect

Did anyone solve this?

I've been watching this issue (in various bug reports) for 
some time. I compiled today's snapshot php5.1-200603022330, 
and the bug is fixed (I triple checked just to make sure)! 
PHP 5.1.2 still exhibits the bug.

Thank you, thank you! I'm finally going to be able to switch 
to PHP 5 when 5.1.3 comes out.

For reference, I'm using PHP5.1.1/5.1.2 on OS X 10.3/10.4 
(both client and Server versions). PHP 4.3.11 has been solid 
for me.

Thanks again!

I'm afraid I din't commit any fixes that may affect this issue, so you just changed something in your environment, that fixed it.
But if the issue doesn't exist anymore, I close the report.
Feel free to reopen it, if you find some more info.
