RE: db-connectin is working fine, but is it pooling?
Write a test connection page and stress test it with a lot of virtual clients. That way, you will have more than 1 connection opened to ypur pool. -Original Message- From: Trond Hersløv [mailto:[EMAIL PROTECTED] Sent: Friday, September 23, 2005 3:24 AM To: Tomcat Users List Subject: RE: db-connectin is working fine, but is it pooling?

RE: db-connectin is working fine, but is it pooling?
I had a similar question while doing connection pooling with Oracle 8i of. OK, if I set my connection pool to 10, why do I only see a 1 connection in Oracle Well, the answer was that when you create a pool of 10, it only starts out with 1 connection, NOT 10 If the connection pool starts needing more than 1 connection, it will create and *keep* new connections. Oracle's connection pooling jar was smart enough to do it. I opened up 4 web browsers and hit my web based app like crazy and saw the acutal physical connections in Oracle jump up to like 5 and stayed at 5 connections. I assume it is the same in MySQL -Original Message- From: KEREM ERKAN [mailto:[EMAIL PROTECTED] Sent: Friday, September 23, 2005 2:50 AM To: 'Tomcat Users List' Subject: RE: db-connectin is working fine, but is it pooling?

RE: db-connectin is working fine, but is it pooling?
I think (not sure as I am not a Tomcat expert) that you can just get 2 connections without closing either - and see that you got 2. - dave -Original Message- From: Trond Hersløv [mailto:[EMAIL PROTECTED] Sent: Thursday, September 22, 2005 6:24 PM To: Tomcat Users List Subject: RE: db-connectin is working fine, but is it pooling?
