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

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.
