Hi we made some pain full experience on z/OS with OJB and connection management. But we was successful to resolve this problem (put there are a lot more problems).
The solution to this problem was: z/OS jdbc driver for Websphere 4.x use per default a aggressive connection management to protect the db2. So the driver closes connection under your knees if this option is set. So you get some errors like this 'method is not valid on a closed logical connection.prepareStatement() SQLSTATE=57015 and SQLCODE=-923' The solution is to disable the aggressive connection management by removing the bboax.jar file from the class path. :-b regards Matthias Roth Bundesamt f�r Informatik und Telekommunikation BIT Office f�d�ral de l'informatique et de la t�l�communication OFIT Ufficio federale dell'informatica e della telecomunicazione UFIT Monbijoustrasse 74, CH-3003 Bern Tel. ++41 (0)31 325 84 68 Fax ++41 (0)31 325 97 54 [EMAIL PROTECTED] http://www.bit.admin.ch/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
