JINFO(1)

NAME
jinfo - generate Java configuration information for a specified Java process

SYNOPSIS
Note: This command is experimental and unsupported.

jinfo [option] pid

option
    This represents the jinfo command-line options. See Options for the jinfo Command.

pid The process ID for which the configuration information is to be printed. The process must be a Java process. To get a list of Java processes running on a machine, use either the ps command or, if the JVM processes are not running in a separate docker instance, the jps command.

DESCRIPTION
The jinfo command prints Java configuration information for a specified Java process. The configuration information includes Java system properties and JVM command-line flags. If the specified process is running on a 64-bit JVM, then you might need to specify the -J-d64 option, for example:

    jinfo -J-d64 -sysprops pid

This command is unsupported and might not be available in future releases of the JDK. In Windows Systems where dbgeng.dll is not present, the Debugging Tools for Windows must be installed to have these tools work. The PATH environment variable should contain the location of the jvm.dll that's used by the target process or the location from which the core dump file was produced.
