# jinfo-openjdk17(1)

generate Java configuration information for a specified Java process

## 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.

## OPTIONS FOR THE JINFO COMMAND

**Note:**

If none of the following options are used, both the command-line flags and the system property name-value pairs are printed.

- **-flag *name***

  Prints the name and value of the specified command-line flag.

- **-flag \[+\|-\]*name***

  Enables or disables the specified Boolean command-line flag.

- **-flag *name*=*value***

  Sets the specified command-line flag to the specified value.

- **-flags**

  Prints command-line flags passed to the JVM.

- **-sysprops**

  Prints Java system properties as name-value pairs.

- **-h or -help**

  Prints a help message.
