# Select Buffer Pool

SYSBPM provides functions for displaying and administrating the buffer pools (including the BP cache) defined for your Natural system environment. A buffer pool not defined on the current Natural session at startup needs to be selected before it can be administrated.

This section covers the following topics:

- Invoking Select Buffer Pool

- Displaying Buffer Pools

- Resetting a Buffer Pool

## Invoking Select Buffer Pool

To invoke Select Buffer Pool

1. In the SYSBPM Main Menu, enter Code `S`.

   Oder:
   Enter the following SYSBPM direct command:

       SELECT BP

   The Select Buffer Pool window appears with the following information on your current buffer pool (global or local) and on all other global buffer pools currently available in your Natural system environment:

   BPNAME | The name of the buffer pool.
   Type | The type of the buffer pool such as `Global Nat`, `Local Nat`, `Global Sort`, `Edit` (Editor), or `Mon` (Monitor).
   Status | The current status.
   Preload | The name of the preload list (if loaded).
   Address | The address of the buffer pool.
   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 buffer pool that you want to select and press ENTER. Note that only buffer pools of type `Natural` or `Sort` can be selected, buffer pools of another type can only be displayed. The specified buffer pool is now defined in your current session and the contents of the buffer pool-related fields (as mentioned above) displayed on top of the SYSBPM Main Menu is changed accordingly.

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

## Displaying Buffer Pools

To display the buffer pools available in your Natural system

- Enter the following SYSBPM direct command:

      DISPLAY BUFFERPOOL

  Oder:
  Perform the first step of the instructions on Invoking Select Buffer Pool

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

## Resetting a Buffer Pool

To reset a buffer pool

- Enter the following SYSBPM direct command:

      RESET BUFFERPOOL

  SYSBPM switches back to the buffer pool originally defined for your current Natural session and the contents of the buffer pool-related fields (as mentioned in Invoking Select Buffer Pool) displayed on top of the SYSBPM Main Menu change accordingly.

  Oder:
  Invoke the Select Buffer Pool function (described earlier) and select the startup buffer pool.
