Administration of the Locking Adapter Service Using the Console

Use

You can also manage the locking adapter service from the command field. You have to use this method, if the visual administrator is not running or there are problems with it, (such as connecting to the server process).

Prerequisites

You can only follow the procedure below, if the server process has been started directly from a console, and not with the Microsoft Management Console.

If the J2EE engine has been started from the MMC, you can use telnetto manage the server from using the console. Follow the procedure below:

...

       1.      Open a command prompt and enter telnet localhost <port>, where <port> is the telnet port of the dispatcher.

       2.      Enter jump.

The standard cluster elements available are displayed. In a central installation this is the server process.

       3.      Enter jump <server>, whereby <server> is the ID of the server process.

You can now continue with the procedure from point 2.

Procedure

...

       1.      Go into the console in which the server process is running.

       2.      Enter man. All the groups and functions that you can call are now displayed.

       3.      If the group locking is not yet available, enter add. All the groups that are currently not active are displayed, including the locking group. Enter add locking. If you now enter man again, you will see that the LOCKING has been added to the list. It has the following functions:

¡        DISPLAY_LOCKS  

¡        ADD_LOCK

¡        REMOVE_LOCK    

¡        REMOVE_LOCKS

¡        REMOVE_LOCK_CUMULATIVE RESET_LOCKING_TIME_STATISTICS

¡        DISPLAY_LOCKING_TIME_STATISTICS

You can also access all these functions in the visual administrator.  They are described in Locking Adapter Service. The lock operations ADD_LOCK and REMOVE_LOCK* are described in Creating and Releasing Locks.
