There should be log files or error messages on the console. It seems you have put an error somewhere in any of the configfiles. It's not at all a question of the ports not being allocated. Take a step back and make tomcat launch again. After that we figure out where you have to set the options... Please detail how you start tomcat and show the output of startup (the beginning and last lines should be enough). Again, don't put any java options for tomcat in any global environment options (JAVA_OPTS, CATALINA_OPTS) in your shell. Only in setenv.sh .

Re: [EXT] Datadog _ JMX Integration facing connection issues.
Hai Chuck.,
Thanks for jumping in.,
thats what my concern is.
as previously added by Chris, I have added my annotations in Catalina_opts .,
Which is preferred by Java_Process for adding the annotations., But Here by
using catalina_opts., they are not reflecting.
where as adding them in java-tool-options., Makes a process with Tomcat and a
process that listens on the mentioned port., but throws port is already
binded., as its an environment variable, its already looking for a port, where
as its already created., throws binding error.
Yesterday ., I thought of adding both the formats, adding java_tool_opts and
Catalina opts., inorder to utilize the previous thigns., as below
- name: JAVA_TOOL_OPTIONS
value: {{ .Values.deployment.javaVMMemoryArgument }}
- name: POD_IP
valueFrom:
fieldRef:
fieldPath: status.podIP
- name: CATALINA_OPTS
value: >-
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=49151
-Djava.rmi.server.hostname=$POD_IP
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Xms2048M -Xmx10240M
Java_tool_opts are as : -XX:+UseStringDeduplication -XX:+UseContainerSupport
-Dcom.sun.management.jmxremote
just added to initiate a JMX process.,
but nothing is working out.,
I would like to request you for further inputs

That shows only the grep process looking for catalina, not anything using
catalina. If Tomcat were actually running, you’d see something like this

Re: 9.0.83 addSslHostConfig JMX Operation Regression (Sample Code Attached)
The object and operation I'm trying to address is Catalina -->
ProtocolHandler --> --> --> operations --> addSslHostConfig.
The parameters are an SslHostConfig object and the boolean value "true".
The operation is "addSslHostConfig".
The code I sent in the previous message works 100% of the time in 9.0.82.
In 9.0.83, it works about 50% of the time. I can always query that the
operation exists, but roughly half the time it will fail with a JMX
exception saying that the operation does not exist.
I am not positive, but I believe the behavior in 9.0.83 might have to do
with the fact that the catalina java code now has a one argument and two
argument variant of the same method.

Good question. What is pid #1? Do those port numbers make any sense for
your Tomcat-based service?
Is Tomcat even running? Try 'ps aux | grep catalina' to see if there are
any. Are you launching Tomcat using catalina.sh / startup.sh or similar?
Or are you running Tomcat "embedded" within your own application?

All,
I've been doing some testing, and I'm pretty sure the addSslHostConfig
operation on ProtocolHandler is busted in 9.0.83.
In versions prior to 9.0.82, you can call the operation with a single
argument of type SSLHostConfig.
In 9.0.82, that contract seems to have been broken, and you had to call
it with two arguments: an SSLHostConfig and a boolean.
In 9.0.83, it seems as though both operations are present, but which one
is actually accessible at runtime is non-deterministic.
This behavior presents through a direct invoke(...) call and via a JMX
Proxy object instantiated through JMX.newMBeanProxy.
I have attached a sample file that reproduces the behavior (sometimes,
as it is nondeterministic).
Is this a bug, or am I simply using the available feature incorrectly?
If it is the former, how do I formally report this? If it is the
latter, what is the "correct" way to call this operation from JMX?
I think your attachment was stripped. Can it be posted in-line?
