Thread pool per webapp?
Hi,
I am wondering whether Tomcat supports thread pool configuration for
each webapp. My understanding is that all webapps share the pool
configured for the connector.
Let's say I have webapps A and B, and A is more critical webapp. Let's
say my connector's pool size is 100, and there are 100 concurrent
requests destined for A and B each (so total 200 requests here). I
would like to allocate 70 threads to process A's requests, and only 30
for B's.
Is this something that Tomcat supports? If not, what would be a good
alternative strategy for it? I am thinking of using a RequestProcessor
to reject requests depending on its destination but that is not very
elegant as requests are rejected instead of being queued.
Thanks in advance.
Regards.

This also gives good isolation between the web apps. The chances of a
problem with one impacting the other are slim.
If you want a single Java process, you could look at using multiple
service elements since connectors are associated with a service.

No argument here. I don't see any other way do to what the OP wanted.

Why not, as i asked before, just start two tomcats? - not pretty but
it works...
ie:
Tomcat1 (webapp1) - Port 8080
Tomcat2 (webapp2) - Port 8081
- Then setup tomcat1 with 70 threads, and tomcat2 with 30 threads....

Quoting the original question:
"Let's say I have webapps A and B, and A is more critical webapp. Let's
say my connector's pool size is 100, and there are 100 concurrent
requests destined for A and B each (so total 200 requests here). I
would like to allocate 70 threads to process A's requests, and only 30
for B's."
Allocating a portion of the total number of threads to a specific webapp
is partitioning the thread pool. Think of it as analogous to
partitioning a drive. The term seemed to fit very well when I wrote the
message.

Dave-
to look at all of the properties of all the attributes you can do so by interrogating jmxproxy ..assuming tomcat is running on localhost and
listener is configured on 8080
http://localhost:8080/manager/jmxproxy/?qry=*%3Atype%3DRequestProcessor%2C*
I guess I dont understand the nomenclature of "partition threads between webapps" maybe you can explain this to us?
I have a servlet which lists free and working threads ..more to come when completed later on this weekend..

As a quick hack....
If you only want to partition between 2 webapps you could always use
the nasty method of using 2 tomcats. The other alternative would be
to configure a second HTTP connector, and then use one for the one
webapp, and the other for the second.

Well I was actually holding off because the internal threading of tomcat
isn't my area. But if you insist, I have never seen any configuration

I wouldn't have the list without it(?) though, makes light work to have

Maybe we can design a test?

Apparently. Works fine for me, and all of Chris' messages do show up in
the archive. Something is broken on your end.

Not sure - I understand Cockney (used to live near London), but I sure
don't understand Martin.

I'd love to say otherwise, but Wikipedia says "Doolittle". Still apt?

Wow. That would explain a lot. I might take issue with the term
"expert" in this case, though...
What was Eliza's last name? Could Martin be a relative?

Tomcat List,
Does anyone else suspect that Martin is actually an expert system
designed to read and respond to mailing list posts, but is totally
failing the Turing test?

Subject: Thread pool per webapp?
Hi,
I am wondering whether Tomcat supports thread pool configuration for
each webapp. My understanding is that all webapps share the pool
configured for the connector.
Let's say I have webapps A and B, and A is more critical webapp. Let's
say my connector's pool size is 100, and there are 100 concurrent
requests destined for A and B each (so total 200 requests here). I
would like to allocate 70 threads to process A's requests, and only 30
for B's.
Is this something that Tomcat supports? If not, what would be a good
alternative strategy for it? I am thinking of using a RequestProcessor
to reject requests depending on its destination but that is not very
elegant as requests are rejected instead of being queued.
Thanks in advance.
Regards.

You could do this by fronting Tomcat with a web server like Apache httpd
or a proxy server, and just use two different connectors. I think this
would be a more elegant solution than trying to hack-together a
short-circuiting, load-balancing RequestProcessor (probably a Filter
would be better, but not by much).
