Thanks for the response..
as you suggested., I tried adding my annotations in CATALINA_OPTS., Instead of
Java_Opts and Java_tool_options.,
But its not even working out., Java process is not getting created., and port
is not bound to any process.
Let me know if I am missing anything.
Okay. Can you please summarize the current situation? I think you've
made a few changes, etc. so it would help to know the current state.
Stop Tomcat and any other related services, delete all appropriate log
files, etc. and start Tomcat (or attempt to). Then post any output that
is relevant, and if you get things like "address in use" then please
post the details about which process id owns that port and the full
command-line that launched that process.
Thanks,

Firstly thanks for adding a point me in asking me to check, if the annotations
are reflecting in the Java process, which opened me a door to add the concerned
annotations in correct place., by adding in java_tool_options in stead of
Java_opts.
You will probably want to use CATALINA_OPTS instead of any of the other
ones. JAVA_TOOL_OPTS isn't an environment variable regognized by Tomcat.
You certainly don't want to use JAVA_OPTS, because Tomcat uses JAVA_OPTS
any time it invokes a JVM. For example, running bind/digest.sh doesn't
need to have the JMX subsystem starting-up and trying to grab a port.
JAVA_TOOL_OPTS is an environment variable used by JVM-launching
processes, like jps for example...
yeah they are reflecting and creating a Java Process.
but I am facing a problem here., while i am checking JSP, Thats : the port i
am using here to enable JMX is been opening a process with the mentioned port
and at the same time shows port is being used.:
root@lab1workflow4scalsvc2zus1-deployment-577d856494-ftb22:/# jps
Picked up JAVA_TOOL_OPTIONS: -Xms2048M -Xmx10240M -XX:+UseStringDeduplication

-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.port=49151
-Djava.rmi.server.hostname=tomcat.default.svc.cluster.local
-javaagent:/datadog-lib/dd-java-agent.jar

-XX:ErrorFile=/datadog-lib/continuousprofiler/tmp/hs_err_pid_%p.log
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port

java.net.BindException: Address already in use (Bind failed)
Yes: you have set JAVA_TOOL_OPTS and then run jps. jps is trying to bind
to your port which is aready bound by your Tomcat process.
The solution is to use only CATALINA_OPTS to set these options.
