DevOps, CI/CD and Automation

Hello,

I am trying to use Oracle for the first time because I am developing a PHP application and the customer decided half way into the project that later he wants to use Oracle. He will be using Oracle 9.2.

I decided to first give it a try in my Windows XP box.
Oracle is up and running, I also created a database and a user and I am able to connect using SQL+.

My PDO connection test script looks like this:
<?php
try {
$dbh = new PDO("oci:dbname=mydatabase;charset=AL16UTF16", "myusername", "mypassword");
} catch (PDOException $e) {
echo "Failed to obtain database handle " . $e->getMessage();
}
?>

So I already found out that the "oci:" must be in lower case and I also was able to find out the charset which my database installation uses.

Now I keep getting ORA-01017. Interesting is, that I do not get "ORA-01017: invalid username/password; login denied" but really only "ORA-01017:", so the colon at the end is there, but no clear text message.

After finding this article http://www.dbmotive.com/oracle_error_codes.php?errcode=01017 I tried turning on auditing. I do now have a table dba_audit_session, it only has one column, though, which is called OS_USERNAME. Each time my PDO connection fails one line is added to this table, which looks like this:
MYCOMPUTERNAME\mycomputerusername

What does this mean? Does PHP/PDO, called via Apache, not hand over the given username/password but try to connect via some single sign on thing?

Just for the fun of it I already tried to create users with names like "mycomputerusername" and "MYCOMPUTERNAME\mycomputerusername" but still I couldn't log in.

Any hints? Any more possibilities for finding more logging information?

Cheers,

Axel
