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!!.

Hope this helps you.

 Hi,
 I've used DDConnectionBroker.jar pooling software provided free by
 DevDaily.com. It gives  connection pooling facility.I've tested the
pooling
 software with a sample java program but it doesn't seem to have any memory
 leak problem.
 Is there any other pooling software available which I can use.

 Regards
 Rajesh

 Have you used any pooling software?How can you achieved connection

 Actually we had same problem and we got the solution.

 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.

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.

2002-05-13 Thread Brett Porter

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
