Select Buffer Pool

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 Select Buffer Pool function and the SYSBPM direct commands provided for displaying and resetting buffer pools.


Invoking Select Buffer Pool

Start of instruction set To invoke Select Buffer Pool

  1. 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.

  2. 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.
