.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 \&.
