Selecting a message pool is done in a similar way as selecting a buffer pool:

• Invoking Select Message Pool

• Displaying Message Pools

• Resetting a Message Pool

---

Invoking Select Message Pool

To invoke Select Message Pool

1. In the SYSBPM Main Menu, enter Object Pool M and Code S.

   Or:
   Enter the following SYSBPM direct command:

   SELECT MP

   The Select Message Pool window appears with the following information on your current message pool and on all other message pools currently available in your Natural system environment:

   BPNAME	The name of the message pool.
   Type	MSG, the type for message pools.
   Preload	The name of the preload list (if loaded).
   ALET	The term ALET (for Address List Entry Token) identifies an index for accessing the dataspace.
   Loc	The location of the buffer pool indicated by HostID and SubsID (subsystem ID).

   For further information on the fields, see SYSBPM Main Menu - Fields, Functions and Commands.

2. In column C, enter any character in front of the message pool that you want to select and press ENTER. The specified message pool is now defined in your current session and the contents of the message pool-related fields (as mentioned above) displayed on top of the SYSBPM maps is changed accordingly. Note that only the functions L (List Objects), D (Delete Objects), and M (Message Buffer Pool Statistics) or their respective direct command are available.

Once you have selected a message pool from the Select Message Pool window, all SYSBPM functions apply to this message pool. Your Natural session itself, however, will continue to run with the message pool that was used when the session was started.

Displaying Message Pools

To display the message pools available in your Natural system environment

• Enter the following SYSBPM direct command:

  DISPLAY MP

  Or:
  Perform the first step of the instructions on Invoking Select Message Pool

  Or:

  The Display Message Pool window appears which provides the same information as described for the Select Message Pool window.

Resetting a Message Pool

To reset a message pool

• Enter the following SYSBPM direct command:

  RESET MP

  SYSBPM switches back to the message pool originally defined for your current Natural session and the contents of the message pool-related fields (as mentioned in Invoking Select Message Pool) displayed on top of the SYSBPM maps is changed accordingly.

  Or:
  Invoke the Select Message Pool function (described earlier) and select the startup message pool.
