ID: 39929 Comment by: mfaust at usinternet dot com Reported By: aloucks at cofront dot net Status: Assigned Bug Type: PDO related Operating System: Linux 2.4.31 PHP Version: 5.2.0 Assigned To: wez New Comment:
I get the same error running PHP 5.2.4, Windows XP SP2, SQL Express 2005, and IIS 5.1. I normally don't use the persistent connection option but it temporarily fixes another issue that I have .Not sure if it's related but occasionally I get an error message in the event viewer stating Out of process application '/LM/W3SVC/1/Root/ticket' terminated unexpectedly. For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I create a new connection using $this->db_conn = new PDO('mssql:' . $this->conn_str, $this->username, $this->password); but after sometime I get the error above and then my connect statement above no longer takes milliseconds but now takes about 2-3 seconds and get: Event Type: Information Event Source: MSSQL$SQLEXPRESS Event Category: (2) Event ID: 17137 Date: 12/14/2007 Time: 1:01:11 PM User: N/A Computer: my_pcname Description: Starting up database 'my_dbname'. in the event viewer every time I create a new PDO connection. The only way to solve this is to run the above connect statement but add the array(PDO::ATTR_PERSISTENT => true) parameter. It will give me a warning but the next time I run the connect statement without the persistent option it only takes a few milliseconds to create the connection and no events are logged in the event viewer. The errors seem to happen after about 15 minutes or so after the last db connection was closed.

A valid and usable PDO object is returned. After 5 calls to PDO::__contruct() with the same parameters the warning goes away and the time to create the PDO object drops from 0.08ms to 0.0004ms. The warning will eventually come back and the connection time will go back up to 0.08ms for a few attempts and then resume back to 0.0004ms. After a fresh apache restart the first 5 connection attempts will always generate this warning. (I assume the pool/cache size is 5) It seems like the connection caching is actually working but a warning is generated when the connection is first established and then again after it eventually times out and a new connection is created. I'm using unixODBC w/ibm iSeriesAccess odbc drivers. This bug seems similar to bug: 39845 (http://bugs.php.net/bug.php?id=39845) but I didn't find any code changes related to it outside the pdo_pgsql dir. Also, I'm not sure if this is related, but PDO::ERRMODE_EXCEPTION, and PDO::ATTR_TIMEOUT also cause warnings to be displayed. I havn't tested any other flags. Connections failures (tested using bad a username) throw exceptions, but sql queries (tested with bad syntax) did not. Reproduce code: --------------- <?php $dbh = new PDO('odbc:dsn', 'user', 'pass', array(PDO::ATTR_PERSISTENT => true)); ?> Expected result: ---------------- The code works but a warning is generated. Actual result: -------------- PHP Warning: PDO::__construct() [<a href='function.PDO---construct'>function.PDO---construct</a>]: SQLSTATE[IM001]: Driver does not support this function: driver does not support setting attributes in ... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39929&edit=1
