Re: Why do I need to restart my server
Sent this a little too early. The reason for the validation query is that if it fails, it will restablish the connection.

RE: Why do I need to restart my server
Hi, The validation query parameter is for DBCP, which would be in server.xml or in your context's context.xml file if you're using the DBCP connection pooling as outlined in the JNDI DataSources How-To document. As an aside: the database server going down is a serious event. You need to carefully code your application for that case if it's likely to happen frequently. The validation query will prevent the pool from handing out bad connections, but it won't: - Magically make valid those connections used by your app at the moment the server goes down, - Necessarily prevent the pool from hanging or waiting for the server to come back up, potentially indefinitely (or throw a SQLException after a timeout, depending on your configuration). So I'm just saying it's not the complete solution ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Adrian Kristiawan [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 10, 2004 7:58 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Why do I need to restart my server Hi, I'm having the same problem, I want to ask which file should I edit according to the changes below?

RE: Why do I need to restart my server
Shapira, I am using my own connection pooling concenpt. The server isn't going down because of my query executions but due to some other reason. If incase it goes down, I need to restart my tomcat. This is a big problem for me. How can I prevent this. Will using the parameters tag in server.xml file solve the problem?

If you're using your own connection pooling nothing you put in server.xml can help: you have to account for the server going down yourself. That's one of the reasons most people don't choose to use their own connection pooling concept.
