Clustering Tomcat 5.0.19
Hi all, I have a problem running Tomcat 5.0.19 on HP Itanium with JRockit
1.4.2.
If I comment out the Cluster & ReplicationValve from server.xml as mentioned
in the docs, leaving the default attribute values my catalina.out shows the
following exception:
GRAVE: Unable to start cluster.

Hello,
Has anyone noticed any problems with usebean tags with I.E. 5.2 on
MAC?
for some reason, session variables are coming thru.
however, if i use regular request.getAttribute() all is well.

Re: access to apache httpd process from tomcat or jk
Posted by "Charles N. Harvey III" <ch...@alloy.com>.
Darn. Thanks for the link, but using a database so far isn't an option.
When you write to the Apache::Notes "table" you can then specify additional
logging parameters for the access.log that will be read out of the little
bit of memory that Notes actually is. The company we are doing the work
for has a very complex reporting tool that is based solely on the access.log
files on all their machines. No databases at all. Pretty aggravating. I
am tasked with researching this, so my research answer might have to be
"no".
Thanks again.

No that won't work.
How about JDBC instead?

access to apache httpd process from tomcat or jk
Posted by "Charles N. Harvey III" <ch...@alloy.com>.
Hello.
A website that we are converting from embedded perl to java writes specific
data to the Apache::Notes table. I just found out what Notes is yesterday,
so it is all pretty new for me. Since embedded perl runs inside the httpd
process it has access to this little bit of memory that gets read with each
request. Tomcat does not run inside the httpd process. That much is
obvious.
But I would still like to write to this Notes table. Is there some way to
gain access to the httpd process from Tomcat? Could I do it through mod_jk
somehow? Does anyone even know what I'm talking about? This is quite
confusing
to me so I'm taking a shot in the dark here to see if anyone else has tried
something similar.
Any tips or pointers to some books or websites is greatly appreciated.
Thanks a lot.
Charlie

>1) context manager doesn't exist.
yep, I am only printing this because of debug. All this means is that you
are a member of the cluster but the server has not fully started up yet.
hence you are receiving messages for a non existent context.
>2)Unable to send replicated message, is server down?
One of your nodes is not responding to messages, either you have some IP
misconfiguration or something else is blocking the messages. I will add more
info to that message to be able to track the problem down
>3) SEVERE: TCP Worker thread in cluster caught 'java.io.IOException:
While reading a message from another node, that node disappeared, got
disconnected. This is also fine and should not affect your system
any other questions, just let me know. someone else can answer your mod_jk
load balancing questions.

Hi All,
I have done clustering of tomcat. I have two different machines running
tomcat which join the cluster. I am testing my application . But in
between I see some errors like
1) context manager doesn't exist.
2)Unable to send replicated message, is server down?
3) SEVERE: TCP Worker thread in cluster caught 'java.io.IOException: An
established connection was aborted by the software in your host machine'
closing channel
It would be grateful if somebody can tell what are these errors for .
And also I have another query.
I have my apache as the load balancer. Currently the requests are
dispatched to each tomcat by the apache. I want this dispatch to happen
in a specific way like one tomcat getting 2 requests and other getting
just one request. Like a ratio of 2:1 . How can I do it ?
Thanks in advance
shyam

works just fine for me.
The configuration file changed between version 0.16 and 0.19, so make sure
you have the 0.19 server.xml
