Java in a Nutshell, 5th Edition

Name

jinfo — Display configuration of a Java process

Synopsis

jinfo [ options ] pid                        // info on local process
jinfo [ options ] executable 
                  core           // info from core file
jinfo [ options ] [process-name@]hostname   // info from remote process

Description

jinfo prints the system properties and JVM command-line options for a running Java process or core file. jinfo can be started in one of three ways:

• Specify the process id of a Java process running locally to obtain configuration information about it. See jps to list local processes.

• To obtain post-mortem configuration information from a core file, specify the java executable that produced the core file and the core file itself on the command line.

• To obtain configuration information about a Java process running remotely, specify the name of the remote host, optionally prefixed by a remote process name. jsadebugd must be running on the remote host.

In Java 5.0, jinfo is experimental, unsupported, and not available on all platforms.

Options

These options are mutually exclusive; only one may be specified.

-flags

Prints only JVM flags, not system properties.

-help, -h

Prints a help message.

-sysprops

Prints only system properties, not JVM flags.
