Hello All;
Can you please tell me the maximum number of nodes a JkManager can handle
without any issues ?
Assume a Quad-Core large memory system.

Hello All;
I can get the JVM memory information using the following SNMP commands.
/usr/bin/snmpwalk -c public -v 2c 172.10.1.11:3000
.1.3.6.1.4.1.42.2.145.3.163.1.1.2.110.1.2
SNMPv2-SMI::enterprises.42.2.145.3.163.1.1.2.110.1.2.1 = STRING: "Code
Cache"
SNMPv2-SMI::enterprises.42.2.145.3.163.1.
Thank you.
So the only way you can do "domain" wide fail-over is by using the "domain"
name given in worker.node1.domain="A" in the Jboss server.xml's jvmRoute ?
And there are no attributes in the workers.property file to do that ?

Hello
I saw this in http://people.apache.org/~mturk/docs/article/ftwai.html
But does not see the balance_members attribute in workers.properties
documentation.
Is it valid ?
worker.node1.type=ajp13
worker.node1.host=10.0.0.10
worker.node1.lbfactor=1
worker.node2.type=ajp13
Great information.
This was what we were looking for.
This will help us a lot in future changes to our cluster and node
infrastructure.
Thank you very much.

Hello!
The documentation says the following on the Busyness Method...
QUOTE
If set to B[usyness] the balancer will pick the worker with the lowest
current load, based on how many requests the worker is currently serving.
This number is divided by the workers lbfactor, and the lowest value (least
checks the Network Latency (Network Response ) through Cping and Cpong
methods as a nodes health as described in

Dear All;
If I am not wrong, the "Busyness" algorithm routes requests to workers by
checking their "Health"
What criteria constitutes as a "nodes" "Health"
and if so,
How is it determined (using the native JVM or else )
Thanks you

for the AJP 1.3 connector port 8009; (Default is 200)
Which parameter is used to do this ?
Question 02
Recently we have made our jboss servers j2ee compliant, earlier i
so now we have to identify if our application is 64bit compatible or 32bit

would not this be a very difficult situation as far as porting to 64bit is
concerned?

Hi;
just to give my 2-cents as a mod_jk user,
i had a similar problem where mod_jk and tomcat was working ok, and apache
was also working ok, but sending blank pages to the user.
noticed the mod_jk log had grown to over 3GB in size, then deleted and
restarted services and started working fine. l

Is there a numbering scheme used when releasing mod_jk stable versions?
For example, some software releases use EVEN numbers as STABLE releases and
ODD numbers as UNSTABLE releases.
Example: 1.2.18 - stable release
1.2.19 - unstable release

After running and collecting jkmanager statistics we noticed that one of

we have left it as it is.

Since this version has fixed the 2^32 - 1 number in Busy column, is it safe

be used as a load balancing method 'B' without a

Is there any logic in the algorithm that monitors Busy values when taking

hi
we has similar issue
we did not mess with prepost values but changed
locking method to pesimistic, and set socket_timeout to 60sec, recycle_time
to 600sec and reply_timeout to 18(ms)
these were recommended by Mladen Turk and now Busy connections are
distributed among all nodes equally.
