  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
