Re: VM size increases.
Hi Rajesh, Why don't you try using 'poolman' from 'www.poolman.com', which is also a free tool and is very good, we have been using it for almost an year and half without any problems!!.

Hi Toru, I'm using jdbc-odbc driver to connect to SQL server. Regards Rajesh That's your problem This is NOT a production quality driver, it's a JDBC type 1 hack. It's got known problems and Sun specifically tells you to use it for testing only. I recommend MS's beta SQL Server driver (which I believe but don't know for sure is mostly a repackaging of a commercial product from Merant)...it's quite good, robust, and fast for most purposes, although it may have some hidden problems that I personally have not run across. Wait, I just checked -- evidently it is no longer beta! http://msdn.microsoft.com/downloads/default.asp?URL=/downloads/sample.asp?u rl=/MSDN-FILES/027/001/779/msdncompositedoc.xml good luck -- this is what I use -- now I will have to upgrade my customers to the release version. fillup On 5/13/02 10:20 PM, Rajesh Mishra [EMAIL PROTECTED] wrote: Hi Toru, I'm using jdbc-odbc driver to connect to SQL server.

Hi fillup, Does the driver for which you have provided the URL, work with sql server 7.0 as on the site it says that it is for SQL Server 2000 and the SPz?

Re: VM size increases.
You are really going to have to look at this more closely before pointing fingers :) 2 days with that many hits is actually a slow leak unless you have a lot of RAM. Still, a leak. The leak could be in the JDBC driver, your code, or any other library (including Tomcat). Have you upgraded to the latest Tomcat (3.2.4) in that line? Your next step will be to use a profiling tool (JProbe, optimize it, etc) to find where the leak is. For instance, you may be using an infrequent circular reference in your code that causes it never to be release in garbage collection. You should have your code modularised enough to be able to beat it outside the servlet container with something like JUnitPerf to see if you have any such problems in certain modules (this is often a little idealistic :) Hope this helps, Brett Rajesh Mishra wrote: I'm using Tomcat3.2 and SQL server2000.
