PHP Version 5.3.3-1ubuntu9, OCI8 1.4.1, Oracle


When I am trying to connect to Oracle instance with another charset then specified in my environment variable NLS_LANG I got an error.

$connectionOptions['oracle'] = array(
    'driver' => 'oci8',
    'dbname' => 'BOOK',
    'user' => 'doctrine',
    'password' => 'doctrine',
    'charset' => 'AL32UTF8',

$em = EntityManager::create($connectionOptions['oracle'], $config, $evm);

Produce error messages:

PHP Warning: oci_error() expects parameter 1 to be resource, boolean given in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Connection.php on line 149
PHP Fatal error: Uncaught exception 'Doctrine\DBAL\Driver\OCI8\OCI8Exception' in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Connection.php:42

There is bug in OCI8Connection::errorInfo() and ::errorCode(). When oci_connect failed, it returns a boolean - false. but oci_error() accepts only resource as parameter. Therefor it is neccessary to check, whether $this->_dbh is resource.

When I've fixed the error handling, I've got the right error, why I couldn't connect to Oracle:

PHP Fatal error: Uncaught exception 'Doctrine\DBAL\Driver\OCI8\OCI8Exception' with message 'ORA-12154: TNS:could not resolve the connect identifier specified' in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Exception.php:28

That's because oci_connect accepts as connection string only TNS name, or Oracle Connection string. But ;charset=* in TNS name or connection string is invalid. oci_connect has 4th parameter charset for that purpose.

Can you help me. I'm having same problem. But your link doesn't work.

You must have very old source code. The bug was fixed 2 years ago. Just compare your OCI8 driver with https://github.com/doctrine/dbal/tree/master/lib/Doctrine/DBAL/Driver/OCI8
