Description:
------------
PDO_OCI 1.0
Oracle 10GR2(x86_64)

For the moment it seems that it isn't possible to connect to an oracle database with a priviledged connection (as sysdba).

In some cases this could be very useful to connect as sysdba.

Maybe this can be done via a connection dsn paramter like session_mode=sysdba or something like that.

So a full connection dsn could be:
oci:dbname=myoraclesid;session_mode=sysdba

Kind regards,
Sven Zurnieden

Reproduce code:
---------------
<?php
$connect_dsn = 'oci:dbname=myoraclesid';
$oracle_uname = 'sys';
$oracle_upass = 'syspasswd';

try{
    $database = new PDO($connect_dsn, $oracle_uname, $oracle_upass);
    $database->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $database->setAttribute(PDO::ATTR_CASE, PDO::CASE_LOWER);
    $database->setAttribute(PDO::ATTR_ORACLE_NULLS, true);
    $database->setAttribute(PDO::ATTR_PREFETCH, 1000);
}
catch(PDOException $e){
    echo $e->getMessage() . ' in ' . $e->getFile() . ' on line ' . $e->getLine() . "\n";
}
?>

Expected result:
----------------
Connection as sysdba to an oracle database.

Actual result:
--------------
SQLSTATE[HY000]: OCISessionBegin:: ORA-28009: connection as SYS should be as SYSDBA or SYSOPER (/root/install/php/php-5.1.1/ext/pdo_oci/oci_driver.c:514) in /usr/local/httpd/htdocs/ora_mgmt/pdo_connect.php on line 30

hi, since Zend Framework provides Zend_DB class based on PDO, it would be very cool to have privileged sessions implemented.

It should be quite simple adding a new variable to the DSN:
struct pdo_data_src_parser vars[] = {
		{ "charset",  NULL,	0 },
		{ "dbname",   "",	0 },
		{ "credentials",   "OCI_DEFAULT",	0 }
	};

and passing the correct parameter to OciSessionBegin() call...

kind regards

Adding privileged connections opens a potential security hole.  If the webserver runs as an OS user with Oracle dba or oinstall privilges it could be possible a hacker to gain high level access to the database.

The oci8 extension added a php.ini parameter to allow privileged connections for users who want to take the risk.

PDO_OCI patches for something similar are welcome, as are a list of use cases where you would find the feature beneficial.
