SYSBPM provides functions for displaying the buffer pools defined for your Natural system environment and selecting a buffer pool other than the buffer pool used by your current Natural session at startup.
This section provides information on the function and the SYSBPM direct commands provided for displaying and resetting buffer pools.
To invoke
In the SYSBPM Main Menu, enter the following function code:
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 further 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,
Global DL/I, 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.
In column C, enter any character to select a buffer pool of the type Natural, DL/I or Sort (all other buffer pools can only be displayed) and press ENTER. 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 has 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 startup buffer pool.
To display the buffer pools available in your Natural system
Enter the following SYSBPM direct command:
DISPLAY BUFFERPOOL
The Display Buffer Pools window appears which provides the same information as described earlier for the Select Buffer Pool window.
To reset the 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.
Or:
Invoke the function (described earlier) and select the
startup buffer pool.
