| Hi all,
We are planning on running multiple Websphere JVM's for different
applications on the same box. Some people are proposing using a
single id to run these jvm's but I feel it is better to have different
id's for the sake of 1)security
2)if we need to hardkill a process it would be harder to figure out
which one to kill 3)Resource utilizations by running top etc would be
harder to predict.
I would like to hear from everybody about the pros and cons.
Thanks

The only con is the possible increase in support time because of the
different IDs. There's no technical reason against it.

| We run multiple JVMs on the same box but we use same id for all application.
If you know which logs to check (and you should if you are admin) then
you can figure out in a jiffy which name of application server associated
with JVM
You can also write some scripts (wsadmin) to tell you this info at the press
of a command.
From security point of view my personal opinion is to not run any JVM as
root.

| Hi,
The PID are generated under the logs folder (ServerName.pid) and they
should tell you which Java process is associated with which server
when you look at top.
The same applies to kill as well.
