The remote debug server hostname or IP address. See

The jinfo 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 -J-d64 option, for
example: jinfo-J-d64 -sysprops pid.

This utility is unsupported and might not be available in future
releases of the JDK. In Windows Systems where dbgeng.dll is not
present, Debugging Tools For Windows must be installed to have these
tools working. The PATH 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, set
PATH=%JDK_HOME%\jre\bin\client;%PATH% .


Prints both command-line flags and system property name-value

-flag name
Prints the name and value of the specified command-line flag.

-flag [+|-]name
