I need to set up PHP to work on a Windows 2000 machine with IIS 5, PHP 4.05 and Oracle 8.0.5 installed. I was having problems with the connection and kept getting all kinds of errors about the TNSNAMES file, but now I'm getting this error. Warning: _oci_open_server: ORA-12699: Native service internal error in c:\inetpub\wwwroot\radar\index.php on line 6 Here's the code I'm using: <? $db = "(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 22.214.171.124)(PORT = 1522)) (CONNECT_DATA = (SID = radw)) )"; $dbh = ocilogon("system","manager","$db"); ?> Can anyone help with this problem?? Thanks!!!!
