jinfo - Generates configuration information. This command is experimental and unsupported.

 

jinfo [ option ] pid

 

jinfo [ option ] executable core

 

jinfo [ option ] [ servier-id ] remote-hostname-or-IP

option The command-line options. See Options.

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 the jps(1) command.

executable The Java executable from which the core dump was produced.

core The core file for which the configuration information is to be printed.

remote-hostname-or-IP The remote debug server \f3hostname or \f3IP address. See jsadebugd(1).

server-id An optional unique ID to use when multiple debug servers are running on the same remote host.

The \f3jinfo command prints Java configuration information for a specified Java process or core file or a remote debug server. The configuration information includes Java system properties and Java Virtual Machine (JVM) command-line flags. If the specified process is running on a 64-bit JVM, then you might need to specify the \f3-J-d64 option, for example: \f3jinfo\f3-J-d64 -sysprops pid.

This utility is unsupported and might not be available in future releases of the JDK. In Windows Systems where \f3dbgeng.dll is not present, Debugging Tools For Windows must be installed to have these tools working. The \f3PATH environment variable should contain the location of the jvm.dll that is used by the target process or the location from which the crash dump file was produced. For example, \f3set PATH=%JDK_HOME%\ejre\ebin\eclient;%PATH% .

no-option Prints both command-line flags and system property name-value pairs.

-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

Prints a help message.

-help

Prints a help message.
