Hi!

I'm having seriuos issues with this error, i tried almost anything now but i still have this error:

Warning: oci_connect() http://function.oci-connect: OCIEnvNlsCreate() failed. There is something wrong with your system - please check that LD_LIBRARY_PATH includes the directory with Oracle Instant Client libraries in /web/SITE/www/lic/db/db.php on line 19
Connection to Oracle Server lost!
This could be due to a known problem with the Apache webserver. Please restart Apache and you should be ok.

This error occured after upgrading from PHP 5.0.4 to 5.3.1 (also tried 5.2.11 with same error)

I have configured my PHP with:
./configure --with-apxs2=/opt/httpd/bin/apxs --with-mysql --prefix=/opt/php --enable-mbstring=all --with-oci8=instantclient,/usr/lib/oracle/10.2.0.3/client --with-zlib

My LD_LIBRARY_PATH is set via export LD_LIBRARY_PATH to:
LD_LIBRARY_PATH=/usr/lib/oracle/10.2.0.3/client/lib

I also tried different thing like configure it with shared instead of instantclient. etc.
Also i tried to download InstantClient 11.2 and install it throug RPMs, i can see that PHP configures with the client and my PHPINFO looks like this (the wierd is that it also says version 10.2 when i use 11.2 client )

OCI8 Support enabled
Version 1.3.5
Revision $Revision: 289423 $

oci8.persistent_timeout -1 -1

oci8.privileged_connect Off Off
oci8.statement_cache_size 20 20


I've bin struggling with this for 2 days now, and i'm so tired so i can't remember everything i tried, but ask me..

Thanks soo much in advance!!

Reproduce code:
---------------
./configure --with-apxs2=/opt/httpd/bin/apxs --with-mysql --prefix=/opt/php --enable-mbstring=all --with-oci8=instantclient,/usr/lib/oracle/10.2.0.3/client --with-zlib

Expected result:
----------------
Connection success!

Actual result:
--------------
Warning: oci_connect() [function.oci-connect]: OCIEnvNlsCreate() failed

Hi,

I think we had the same problem. After long time poking into fog, we found out that patching the file:

	php5/ext/oci8/oci8.c

with (line 1035):

  /*errstatus = OCIEnvNlsCreate(&OCI_G(env), PHP_OCI_INIT_MODE, 0, NULL, NULL, NULL, 0, NULL, 0, 0);*/
  errstatus = OCIEnvCreate(&OCI_G(env), PHP_OCI_INIT_MODE, 0, NULL, NULL, NULL, 0, NULL);

seams to be a workaround for that problem.
 We have 2 php scripts that insert data into our oracle database. One script always fails and the other script sometimes. Both script use the same underlying class to connect to the database and both scripts call oci_connect with the same parameter.
Adding debug code to the oci8.c file, we found that the call of OCIEnvNlsCreate sometimes failed without an comprehensible reason and the parameter of OCIEnvNlsCreate are not very complicate.
Comparing the oci8.c file from php 5.3 with that of php 5.2 we decided to change the function call. With that patch both php scripts seamed to work. I think, this is not a fix, but a workaround.
