When using Oracle as Database, the Connections of the calender, adress, notes and tasks Apllications to the Database fail. The Error shown in the Web is: "MDB2 Error: not found" In the horde.log the error shows for example as: HORDE [error] [turba] MDB2 Error: not found: [Error message: not a valid connection string or environment variable [ORACLE_SID|TWO_TASK] not set] [pid 15777 on line 452 of "/home/horde/horde-webmail-1.2.6/turba/lib/Turba.php"] Horde itself can open and use the database. I have only very limited knowledge and experience with php and no infrastructure für debugging, but as far as I got (opened my own logfile and dumped variables and arrays), I found out that at some place the connect-string was used as User-Name. See contents of the dsn Array from my own logging: dsn: Array ( [phptype] => oci8 [dbsyntax] => oci8 [username] => horde [password] => HORDE [protocol] => [hostspec] => [port] => [socket] => [database] => dwo/dbrmz.robbienet.local [mode] => [persistent] => ) This is, how it should be (right at the start in the MDB2.php File) And this is, what's passed to the oci8.php for the connection: dsn: Array ( [phptype] => oci8 [dbsyntax] => oci8 [username] => dwo/dbrmz.robbienet.local [password] => HORDE [protocol] => [hostspec] => [port] => [socket] => [database] => dwo/dbrmz.robbienet.local [mode] => [persistent] => ) The username is now the connect-string. Somewhere in the Web I found the hint, that one should set the 'emulate_database' option to false and I tried that, but got no luck - probably I did wrong... I do have a (kronolith) H3 (2.1.5) install, where this all works properly.

So, installation went fine and other database access like setting preferences works fine? Those don't use MDB2, so the problem is probably somewhere in passing the parameters to MDB2. Or rather, like you already found out, in passing the parameters inside MDB2.

Yepp installation went fine, everything is up and running and looks good. The trouble starts, when you actually trying to do something, like create an adressbok. I See established Connections to my database, querying prefs and alarms. Tables with data in, that have been read from and written to include HORDE_ALAMS HORDE_PREFS HORDE_TOKENS IMP_SENTMAIL INGO_RULES ...

The emulate_database option should indeed keep the username from being assigned the database name. Where and how did you set it when you tried that?

Tue, 27 Jul 2010 19:15:31 +0000

It was in a file called /lib/Horde/SQL/Manager.php There is a function: function getInstance($dsn = array()) { // Merge local options with Horde database config. if (isset($GLOBALS['conf']['sql'])) { $dsn = array_merge($GLOBALS['conf']['sql'], $dsn); } unset($dsn['charset']); $options = array('seqcol_name' => 'id', 'portability' => MDB2_PORTABILITY_ALL & ~MDB2_PORTABILITY_FIX_CASE, 'force_defaults' => false, 'emulate_database' => false); ^^^^^^^^^^^^^^^^^^ This is for sure not the right place for doing so, since it affects the other db-drivers, too... I'm a Oracle Database Architect/Developer/Administrator, and have no experience in php-programming, so I decided at this to leave that to the ones who know, what they are doing

Thu, 29 Jul 2010 18:02:28 +0000

I did some debugging: the error is thrown in the connect() function of pear/php/MDB2/Driver/oci8.php The function starts at line 429. The problem is the following part: // if ($this->database_name) { // if ($this->database_name != $this->connected_database_name) { // $query = 'ALTER SESSION SET CURRENT_SCHEMA = "' .strtoupper($this->database_name) .'"'; // $result =& $this->_doQuery($query); // if (PEAR::isError($result)) { // $err = $this->raiseError($result, null, null, // 'Could not select the database: '.$this->database_name, __FUNCTION__); // return $err; // } $this->connected_database_name = $this->database_name; // } // } As you can see, I uncommented all, except for on line. I do have no errors any more in the log and have all features available. But, this is only my workaround and cannot be the final fix. What is done here, as far as I figured out: It checks, if this->database_name is set, and if so if it is different then $this->connected_database_name, which is always true, because $this->connected_database_name is set to an empty string a few lines above. With these conditions fulfilled, it assumes, that we have to switch to a different schema inside the oracle database and issues a "ALTER SESSION SET CURRENT_SCHEMA" which has to fail, because this->database_name is set to the connect-string. It can succeed, only when I connect to schema HORDE inside a database named horde using a tnsnames.ora. That is not unlikely to happen in a testing environment... I think, a few days ago, I saw inside the code, that at some place this->database_name was set to an empty string aftre a successfull connect- which at that time didn't made sense to me - but I can't find it any more. Again, my php-knowledge ends here and I have to pass the ball back to you...

Thu, 29 Jul 2010 19:13:51 +0000

Yes, we purposefully set the conncted_database_name to '' in the sql share driver. This is to workaround an issue with MDB2 not being able to detect when a database connection changes external to it's code. See Bug: 6997 for more detail on this. What is supposed to happen is MDB2 re-selects the database in this case. That is what the commented out code is doing. I have no idea why it's failing, as $this->database_name should be the correct name to connect to. That being said, I'm no oracle expert, so I can't speak to the correctness of the statement being performed there. See if you can add the line: var_dump($result); right before the PEAR::isError() statement to see if you can get a more detailed error message. Unfortunately, if the issue is with code in this file, it's not a Horde issue - as this is from PEAR.
