| .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 |

| \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 |

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

| -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 |
