| 71 | The command-line options\&. See Options\&. |
| 72 | .TP |
| 73 | \fIpid\fR |
| 74 | 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\&. |
| 75 | .TP |
| 76 | \fIexecutable\fR |
| 77 | The Java executable from which the core dump was produced\&. |
| 78 | .TP |
| 79 | \fIcore\fR |
| 80 | The core file for which the configuration information is to be printed\&. |
| 81 | .TP |
| 82 | \fIremote-hostname-or-IP\fR |

| 84 | .TP |
| 85 | \fIserver-id\fR |
| 86 | An optional unique ID to use when multiple debug servers are running on the same remote host\&. |
| 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 \&. |
