Re: Database connection causes slow startup
Thanks for your help. I solved the problem. It turns out the problem was in that fastConnectionFailover option. I disabled that, and it now starts up in 46 seconds.

You'll need to copy and paste the information in your email. Now, it takes around 7 minutes to start. This seems long, but it really depends on how many connections you've configured the pool to initially make and how long it takes to make each connection. Where are you defining your DataSources and what do the definitions look like? Dan

That seems like it should happen pretty quick. A couple thoughts... 1.) Do you have any applications deployed to the server? If so, perhaps it is an application which is causing the startup to take so long. Have you tried starting Tomcat without any applications deployed? If so, how long does it take to startup? 2.) Try making a test connection to your database outside of Tomcat from the same machine. Does the connection take a long time to setup? Dan
