Hello
I wonder if anyone can advise me on this issue. I have a Tomcat 6.X Java /
JSP application which uses connection pooling to access a MySQL database
but, if the application is left for up to eight hours, one of the pages
fails to display the contents of a dataset upon loading.

Hi List,
I have configured Apache 2.2.11 (worker mpm) with mod_jk 1.2.27 and two
nodes of Tomcat 6.0.20
My mod_jk configuration only has the following settings (apart from the port
and IP address settings ofcourse):
worker.tcnodo-11.socket_keepalive=true
worker.tcnodo-11.connection_pool_timeout=

It won't. You want the RemoteAddressValve.
A couple of pointers you can use or ignore as you see fit:
- Use a filter rather than a valve. It is more portable.
- Cache the list of balcklisted IPs if at

Sounds likely.

Try setting this to true.

Thanks for the reply.
Setting testOnBorrow to true is something I'll try but according to:
http://commons.apache.org/dbcp/configuration.html
If testOnBorrow is set to true, the validation query must be set to a
'non-null string'. Presumably this means that the query must always return a
value s

Hello list,
we are about to migrate our webserver cluster from Jetty 5.1.14 to
Tomcat 6.0.20. Currently there are four servers in our cluster with
simple load balancing and no session clustering.
At the moment we are testing Tomcat on 2 nodes of our cluster (also no
session clustering yet).

If you use JSP tags where the JSP body does not directly stream but
needs buffered for the tag to finish processing it (using BodyContent) -
then tomcat will allocate and reuse these. If you are creating pages
with large body contents - this can take *A LOT* of memory. The rational
is to reuse

Hi André.
I actually stopped one server on purpose, to test the mod_jk's behavior.
So the errors are not generated due to an overload or something.
I would love to send you the whole workers.properties file and server.xml,
but unfurtunately at this moment I can't.
In advance I can tell you that b
Thanks, Mark.
1. I just tried to reproduce the issue on my pc. And I couldn't, which
is a good thing. I will try it again later on the server, with which I
had the issue yesterday.
2. OK
3. Can live with that

Thanks for the pointers. That was my original plan but I have been required
to try
and do this with a Valve. The caching is good but I still have to read from
a
database to periodically up the list of IP addresses.

Just for curiosity's sake, what's the source of that requirement?

I suggested a filter but he prefers a valve even though it ties that
functionality to Tomcat.
