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:
To invoke
In the SYSBPM Main Menu, enter
S
.
Or:
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). |

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

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.
