Apache, PHP, and Oracle 11G

Question

Hi,
I have an 11G RAC Setup, and a separate application server that runs php that is presently connecting to MySQL Servers.
I just configured OCI8 in my application server and can see that my configurations are correct using phpinfo().
iam using this code to connect to my RAC 11G:
<?php
if(!$conn = oci_connect('sys', 'opensesame','callbox.oracle'))
$err = oci_error();
trigger_error('Could Not Establish a Connection:'.$err['message'], E_USER_ERROR);
?>
but i get this error:
Warning: oci_connect() [function.oci-connect]: ORA-12154: TNS:could not resolve the connect identifier specified in /var/www/html/oraconn.php on line 6
here's tnsnames.ora in my RAC, using sqlplus via command line works perfectly fine in either nodes of the rac.
LISTENERS_CALLBOX =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = node01-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = node02-vip)(PORT = 1521))
CALLBOX2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node02-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = callbox.oracle)
(INSTANCE_NAME = callbox2)
CALLBOX1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node01-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = callbox.oracle)
(INSTANCE_NAME = callbox1)
CALLBOX =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node01-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = node02-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = callbox.oracle)
am I missing something?

Answer 1

i forgot to include that the tutorial that helped me configure the OCI8 for PHP suggests that i need to create tnsnames.ora in /etc like this:
SERVICENAME =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ip_of_oracle_server)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SID)
(SID = SID)
so I created this:
CALLBOX1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.50.161)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = callbox.oracle)
(INSTANCE_NAME = callbox1)
and did this: export TNS_ADMIN=/etc/
am not sure which part of my tnsnames.ora in the RAC (posted earlier) be copied in /etc/tnsnames.ora in the application server.
