| 52 | jinfo \- Generates configuration information\&. This command is experimental and unsupported\&. |
| 53 | .SH SYNOPSIS |
| 54 | .sp |

| 56 | |
| 57 | \fBjinfo\fR [ \fIoption\fR ] \fIpid\fR |
| 58 | .fi |

| 65 | \fBjinfo\fR [ \fIoption \fR] \fI[ servier\-id ] remote\-hostname\-or\-IP\fR |
| 66 | .fi |
| 67 | .sp |
| 68 | .TP |
| 69 | \fIoption\fR |
| 70 | The command-line options\&. See Options\&. |
| 71 | .TP |
| 72 | \fIpid\fR |
| 73 | 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\&. |
| 74 | .TP |
| 75 | \fIexecutable\fR |
| 76 | The Java executable from which the core dump was produced\&. |
| 77 | .TP |
| 78 | \fIcore\fR |
| 79 | The core file for which the configuration information is to be printed\&. |
| 80 | .TP |
| 81 | \fIremote-hostname-or-IP\fR |
| 82 | The remote debug server \f3hostname\fR or \f3IP\fR address\&. See jsadebugd(1)\&. |
| 83 | .TP |
| 84 | \fIserver-id\fR |
| 85 | An optional unique ID to use when multiple debug servers are running on the same remote host\&. |
| 86 | .SH DESCRIPTION |
| 87 | 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\&. |
| 88 | .PP |
| 89 | 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 \&. |
| 90 | .SH OPTIONS |
| 91 | .TP |

| 94 | .TP |
| 95 | -flag \fIname\fR |
| 96 | .br |
| 97 | Prints the name and value of the specified command-line flag\&. |
| 98 | .TP |
| 99 | -flag \fI[+|-]name\fR |
| 100 | .br |
| 101 | enables or disables the specified Boolean command-line flag\&. |
| 102 | .TP |
| 103 | -flag \fIname=value\fR |
| 104 | .br |
| 105 | Sets the specified command-line flag to the specified value\&. |
| 106 | .TP |
