interact with desktop
Hi all,
I just installed tomcat 4.1 . Maybe you guys can help me find out how to
set it to interact with desktop. I want to see the errors are in my
application . If using ias we can see it by tail -f kjs*.
Rgds,
Nisa

Ok, but did you test TC 5 with the same configuration using JK ? You
could be running in a performance bug when using that connector, related
to whatever you are doing in your application.

2: I don't know ;) the JBoss websites aren't using it yet (since they're
using JBoss 3.2.3)
3: Same.

lb worker issue
Posted by Pete Stokes <st...@quinn-direct.com>.
Hi.
I've got load balancing working with Tomcat 5 (Apache 1.3x), but when I
set the lbfactor to 100 for both Tomcat workers, I get all requests to
the first defined worker.
If I up the lbfactor of the second box, everything goes to that box.
Whilst using the same apache with Tomcat 4, I had it distributing load,
but it's seems to have stopped unless it will do the first x sessions to
one box then swap to the other.
Pete.

Remy,
With just 1 user, it appears 3x as slow. I understand the max throughput
will be better, but did not expect this performance degredation with
just 1 user, I'd assumed slight degredation overall and a lower max users.
Don't suppose you could answer my questions 2 & 3 ?
Thanks,
Pete.

If you're comparing with 5.0.18 with the HTTP connector, I'd like to
point out that the HTTP connector has a higher max throughtput than
using AJP with a native webserver (esp if TC and the native webserver
are running on the same server).
If you want to compare the two releases, you should probably be using
the same configurations ;)

Tomcat 4.1.29v5.0.18 performance
Posted by Pete Stokes <st...@quinn-direct.com>.
I've just got my app load balanced between Apache 1.3 & 2xTomcat 4.1.29,
JK, SunJDK1.4.2, all seperate boxes. I have set heap site (JVM settings)
same as my Tomcat 5.0.18, and guessed minProcessors=100 and
maxProcessors=300 for server.xml's - config different to 5.0.18.
It's appears about 3x as slow as a single 5.0.18.
I have three questions re this:
1) Has any1 experienced this and found a solution?
2) If I can't get T4.1.29 up2speed, and want to loadbalance with T5.0.18
/ Apache 2, do people actually use this in production without any major
issues?
3) If I go point 2, then the only way I've found to provide loadbalancer
redundancy for those versions is LinuxVirtualServer. Is that correct?
Any comments would be appreciated.
Pete.
