Thanks for the further information, I hope that I can work on this problem on friday.
I will try out your workarounds and then get back to you with hopefully positive feedback ;-)

Under (severe) stress, we now sometimes get an "ORA-12519: TNS:no appropriate service handler found" which is a different connection error type but one which can probably be solved easier. Hence the issue in the post is solved, don't use PDO-Oracle and fix Doctrine!!

First try seems successful, although it’s not stress tested yet. We had to change a Doctrine file though, parts of the connection settings were not passed properly. We now have a hard-coded fix in place:

in the class Doctrine_Adapter_Oracle (file: Oracle.php) line 105 we added
$this->config['dbname'] = ‘(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=host.nl)(PORT=1521)))(CONNECT_DATA=(SID=sid)))’;
$this->config['charset'] = ‘AL32UTF8′;

Although the fix is not definitive yet (hard to reproduce the issue because of it’s randomness), it did solve another issue we had (thus Oracle PDO == Experimental == Trouble?).

I don’t know yet, had the day off because it’s my son’s birthday, asked a colleague of mine to check it but he did not get around to it *sighs*. I’m pretty anxious to know if it works though. Cross your fingers. If your try failed, I’m afraid my change to the normal Oracle driver will fail too. Thus using the PDO or normal Oracle driver doesn’t matter …

At least it shouldn’t report the “PDO Connection Error” part because we’re not using PDO?!?!

hi,

so do you have a working solution?
I am using the symfony frameworking with doctrine and i am getting the same error.
Using “oracle” instead of “oci” in the connection string is not working.

There is not very much about that on google. ;-)
