+ − 87 .SH DESCRIPTION
+ − 88 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\&.
+ − 89 .PP
+ − 90 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 \&.
