Connectors and apache with mpm worker
Hi everyone!
I'm doing some performance tests under apache and tomcat using jakarta
connectors.
Searching around, I've read about apache-worker (not jakarta), to make
it multi-process and multi-thread, but I'm having some troubles with
connectors now.
Here is the output of jk_mod_log:
[error] jk_handler::mod_jk.c (2410): Could not get endpoint for
worker=worker1
[info] jk_handler::mod_jk.c (2476): Service error=0 for worker=worker1
And here is my workers.properties:
worker.worker1.port=8009
worker.worker1.host=127.0.0.1
worker.worker1.type=ajp13
worker.maintain=30
worker.worker1.connection_pool_size=1
worker.worker1.fail_on_status=503
worker.list=worker1
If I browse the site, it loads really faster, but with some little more
traffic (2 connections by second), I get all those errors at jk_mod_log.
Can you give me some help? I just can't find what to modify or what is
wrong with my configuration.
Thanks to all!
Martin

Sorry, I forgot that.
Is a CentOS GNU/Linux 5.2, with apache 2.2.10 and tomcat connectors
1.2.27.
Thanks for the advice André.

I think you should state on which platform you're running this, because
it may have an impact on whether it is or not a good idea to use the
worker mpm in the first place.

Thanks for the explain Rainer.
May be I just misunderstood the last paragraph at the description of
"connection_pool_size":
"Do not use connection_pool_size with values higher then 1 on Apache 2.x
prefork or Apache 1.3.x!"
Thanks again for your responses.

Each Apache process has a private connection pool associated with each
AJP13 worker. The size of the pool is determined automatically during
startup. By default it is set to the number of threads in the process.
You decided to overwrite the pool size to 1 :(
The connection_pool_size attribute is only needed for other web servers
like IIS or Sun/Netscape, because we can't determine a useful pool size
automatically for them,
Please read the explanation of "connection_pool_size" on
http://tomcat.apache.org/connectors-doc/reference/workers.html
Where did you get the value "1" from?
Regards,
Rainer

Wow!! That just made the trick!
Please, can you explain me how those changes affects?
Thanks you very much! I've lost all the day trying to resolve this issue
