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 .br Prints the name and value of the specified command-line flag\&. .TP -flag \fI[+|-]name\fR .br enables or disables the specified Boolean command-line flag\&. .TP -flag \fIname=value\fR .br Sets the specified command-line flag to the specified value\&. .TP -flags .br Prints command-line flags passed to the JVM\&. .TP -sysprops .br Prints Java system properties as name-value pairs\&. .TP -h .br Prints a help message\&. .TP -help .br Prints a help message\&. .SH SEE\ ALSO .TP 0.2i \(bu jps(1) .TP 0.2i \(bu jsadebugd(1) .RE .br 'pl 8.5i 'bp
