Lambda Probe admin tool for Tomcat in OFBiz

[Sterling Okura-2]

Hi everyone.  I want to share a helpful tool for those who haven't used it
yet.  Lambda Probe (www.lambdaprobe.org) is an administration & monitoring
tool for Tomcat.  It shows detailed session, system, memory, cluster, and
other info.  It has nice real-time stat updates via ajax.  I finally got
clustering and session replication working with OFBiz and Lambda was
critical in troubleshooting and debugging the setup.

I wrote up a howto for running it in OFBiz hot-deploy at
http://www.bizlift.com/ofbiz/lambda_probe_for_ofbiz.html.  The document is
continuing to be refined and updated, and will eventually be added to
wiki/doc section.  Will also write howto on clustering since there seem to
be several requests throughout the history of the list but no definitive
instructions.

aloha,
sterling

Hello Sterling,

I am interesting on a ofbiz cluster setup with session replication between
two hosts. I have investigated some time on the setup. The log shows   also
cluster.mcast messages but it seems that the broadcast messages are not
receive packets from an other host node. I have also added your catalina
patch from jira. Do you have a configuration example for a two node cluster?


here is my setup the node 1 has 192.168.51.54 the second is configured on

node one:

 <container name="catalina-container"

        <!-- static configuration for tomcat -->

I have absolutely no experience with what you're trying to accomplish
so take this suggestion with that in mind.  I image your container
names need to be unique otherwise the second is likely to override the
first when the XML document is parsed.

Hello Chris,

the config example differs on the host nodes. (not all in the same host). I
suggest the problem could be found in a missing multicast setup on the
linux host nodes?

kind regards
Sebastian

Hi Sebastian,

Sorry I'm slow to respond, I just noticed this message.

First, is your multicast network setup properly?  From shell can you ping
228.0.0.4 and receive replies from from both hosts?  If not, check the
routes you setup for multicasting.

It's weird, but on RHEL 4, I had to comment out the "mcast-bind-addr"
setting so it binds to all addresses, or it wouldn't work.  I originally
tried binding only to my internal VPN address like in your config, but it
would work for some reason.

Another thing to check for is if access to port 45564 is enabled.  You can
try telnetting to that port from one server to the other and see if it
connects.  Might have to adjust iptables or whatever firewall service you
have running.

Not sure what version of OFBiz you're using.  My version was a checkout from
a year ago, so I had to manually update to Tomcat 5.5.20.

Did you get Lambda Probe up and running?  Is the multicasting showing up?

Keep us posted.
