.SH NAME    

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

.SH SYNOPSIS    

.sp     

.nf     

\fBjinfo\fR [ \fIoption\fR ] \fIpid\fR

.fi     

.nf     

\fBjinfo\fR [ \fIoption \fR] \fIexecutable core\fR

.fi     

.nf     

\fBjinfo\fR [ \fIoption \fR] \fI[ servier\-id ] remote\-hostname\-or\-IP\fR

.fi     

.sp     

.TP     

\fIoption\fR

The command-line options\&. See Options\&.

.TP     

\fIpid\fR

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\&.

.TP     

\fIexecutable\fR

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

.TP     

\fIcore\fR

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

.TP     

\fIremote-hostname-or-IP\fR

The remote debug server \f3hostname\fR or \f3IP\fR address\&. See jsadebugd(1)\&.

.TP     

\fIserver-id\fR

An optional unique ID to use when multiple debug servers are running on the same remote host\&.

.SH DESCRIPTION    

The \f3jinfo\fR 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\fR option, for example: \f3jinfo\fR\f3-J-d64 -sysprops pid\fR\&.

.PP

This utility is unsupported and might not be available in future releases of the JDK\&. In Windows Systems where \f3dbgeng\&.dll\fR is not present, Debugging Tools For Windows must be installed to have these tools working\&. The \f3PATH\fR 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%\fR \&.

.SH OPTIONS    

.TP     

no-option

Prints both command-line flags and system property name-value pairs\&.

.TP

-flag \fIname\fR

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

.TP

-flag \fI[+|-]name\fR

enables or disables the specified Boolean command-line flag\&.

.TP

-flag \fIname=value\fR

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

.TP

-flags

Prints command-line flags passed to the JVM\&.

.TP

-sysprops

Prints Java system properties as name-value pairs\&.

.TP

-h

.br

Prints a help message\&.

.TP

-help

.br

Prints a help message\&.
