Is it possible to use a 64-bit Apache (consequently 64-bit mod-jk) with
32-bit Tomcat instances?
Some Tomcats will be co-located with the Apache on the same box and some
will be remote. But all the Tomcats will run on 64-bit Linux kernel?
Hi
Does anyone know if Tomcat is affected by this?
I have Tomcat 5.5.16 with Sun JRE 1.5 patched with TZupdater on RHEL.
Thanks

ftp? You mean telnet or rsh or ssh or something right?
Anyhow, create a different instance of tomcat for each user:
Recursively copy the following directories from CATALINA_HOME to a new
location (say /usr/tomcat/instance_n) to create a new instance:
webapps
temp
shared
conf
logs
Then change the

Since you have windows, shouldn't the mod_jk load library be a dll rather
than so?
I believe you have referenced the incorrect mod_jk.

We have a 12 (tomcat 5.5.16) instance cluster on 4 physical machines running

y low,
most of the time all workers will have no request in processing. So the
busyness counter will always be equal to zero. Then mod_jk will pick on
worker after the other, similar to round-robin.
As soon as there will be real load, behaviour will differ.

Is it possible to change mod_jk's load-balacing algorithm to random (from
round robin)?
If yes, how?
TIA

All webapps listen on the same http port if deployed within the same tomcat
instance.
Your option is to deploy each webapp on its own instance of tomcat, each
listening on a different port. Creating a new instance of tomcat means a
separate JVM with all the additional needs from system resource per
ing, configure
jvmRoute on the Tomcats (most likely you already did this) and then send
a request like:
/my-probe;jsessionid=dummy.my_jvmroute
(with no cookie sent)
This request will be routed to the worker with name/jvm_route "my_jvmroute".
Is that what you were looking for?

Hi
We have a 4 machine configuration.
Each machine has:
1. 3 Tomcat instances (so total 12 instances)
2. 1 Apache with mod_jk (so total 4 Apaches)
The Apaches/mod_jks are fronted by a hardware load balancer.
Each mod_jk load balances across all 12 tomcats.
In other words, you could hit any one of
Another way could be to deploy a single webapp in a single Tomcat instance
so there are no classloading issues.
But of course that will create as many VMs as there are webapps.

Why can't you just put the jars in the WEB-INF/lib of each webapp then?
Then you can have a different version of the jar for each webapp.
Unless of course, tomcat uses the same classloader to load classes for all
webapps.

Jar up the common code into one or more libraries.
Put them somewhere (possibly at the enterprise app level) and add each jar
in each webapp's MANIFEST file.

Sid,
I know of sar but how do I run it?
just by 'sar' command or any other parameters?
I can't afford overhead as this is production;
as to vmstat: just by command or anything else?
Thanks,

"Sharma, Siddharth"
You can use sar or vmstat
They give you system level health.
If you need inside the jvm health you can run the jvm in hprof mode. It adds
plenty of overhead so beware.

I have IBM HttpServer 2.0 (it is an apache essentially) fronting two

I have configured a load balancer worker to spray load across two workers
representing these two tomcat instances.
And it works.
The problem is I do not see a session
