Lock Administration and Monitoring with the Console

As an alternative to the Visual Administrator, you can also manage the Locking Service using shell commands.

Prerequisites

Connect a Telnet client to AS Java as described in Connecting and Working with Telnet, and use the JUMP command to establish a connection to a server process.

Procedure

Enter man in the command line of the Telnet console. This displays all the shell command groups and the associated commands that are available to the shell environment.
To add the LOCKING shell command group to the environment, enter add locking.

Enter man again to display the list of commands available to the LOCKING group. They are the following:
