See \f[B]Options for the jinfo Command\f[R]. .TP \f[I]pid\f[R] 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 either the \f[V]ps\f[R] command or, if the JVM processes are not running in a separate docker instance, the \f[B]jps\f[R] command. .SH DESCRIPTION .PP The \f[V]jinfo\f[R] command prints Java configuration information for a specified Java process. The configuration information includes Java system properties and JVM command-line flags. If the specified process is running on a 64-bit JVM, then you might need to specify the \f[V]-J-d64\f[R] option, for example: .RS .PP \f[V]jinfo -J-d64 -sysprops\f[R] \f[I]pid\f[R] .RE .PP This command is unsupported and might not be available in future releases of the JDK. In Windows Systems where \f[V]dbgeng.dll\f[R] is not present, the Debugging Tools for Windows must be installed to have these tools work. The \f[V]PATH\f[R] environment variable should contain the location of the \f[V]jvm.dll\f[R] that\[aq]s used by the target process or the location from which the core dump file was produced. .SH OPTIONS FOR THE JINFO COMMAND .PP \f[B]Note:\f[R] .PP If none of the following options are used, both the command-line flags and the system property name-value pairs are printed. .TP \f[V]-flag\f[R] \f[I]name\f[R] Prints the name and value of the specified command-line flag. .TP \f[V]-flag\f[R] [\f[V]+\f[R]|\f[V]-\f[R]]\f[I]name\f[R] Enables or disables the specified Boolean command-line flag. .TP \f[V]-flag\f[R] \f[I]name\f[R]\f[V]=\f[R]\f[I]value\f[R] Sets the specified command-line flag to the specified value. .TP \f[V]-flags\f[R] Prints command-line flags passed to the JVM. .TP \f[V]-sysprops\f[R] Prints Java system properties as name-value pairs. .TP \f[V]-h\f[R] or \f[V]-help\f[R] Prints a help message.
