Synopsis
jstatd options
Description
jstatd
is a
server that provides information about local Java
processes to
the jps and jstat programs
running on remote hosts.
jstatd uses RMI and requires special security
permissions to run successfully.
To start jstatd, create the following file and
name it jstatd.policy:
grant codebase "file:${java.home}../lib/tools.jar {
permission java.security.AllPermission
}
This policy grants all permissions to any class loaded from the
JDK's tools.jar JAR file. To
launch jstatd with this policy, use this command
line:
% jstatd -J-Djava.security.policy=jstat.policy
If an existing rmiregistry server is running,
jstatd uses it. Otherwise, it creates its own
RMI registry.
Options
- -n rminame
-
Binds the jstatd remote object to the name
rminame in the RMI registry. The default name is
"JStatRemoteHost", which is what
jps and jstat look for. Use
of this option requires rminame to be used
in remote jps and jstat
invocations.
- -nr
-
Tells jstatd that not to start an internal RMI
registry if none are already running.
- -p port
-
Looks for an existing RMI registry on
port, or starts one on that port if no
existing registry is found.
