WebLogic Server Command Reference

## HELP

Provides syntax and usage information for all WebLogic Server commands (by default) or for a single command if a command value is specified on the HELP command line.

You can issue this command from any computer on which the WebLogic Server is installed. You do not need to start a server instance to invoke this command, nor do you need to supply user credentials.

### Syntax

>     java weblogic.Admin HELP [COMMAND]

### Example

In the following example, information about using the `PING` command is requested:

>     java weblogic.Admin HELP PING

The command returns the following:

>         -username <username> -password <password>
>         PING <roundTrips> <messageLength>

>     Where:
>     roundTrips = Number of pings.
>     messageLength = Size of the packet (in bytes) to send in each ping. The default
>     size is 100 bytes. Requests for pings with packets larger than 10 MB throw exceptions.

>     ing on a port and is ready to accept WebLogic client requests.
