SYSBPM Direct Commands

The SYSBPM direct commands described in this section can be used to directly execute SYSBPM utility functions or navigate in SYSBPM screens in online or batch mode. For additional SYSBPM direct commands that only apply to particular screens, refer to the sections where the individual SYSBPM functions are documented.

SYSBPM direct commands that refer to the BP cache or buffer pool hash table only apply to buffer pools of the type Natural.

The following table lists all SYSBPM direct commands (including subcommands) provided, the parameters that can be used with the commands, and the equivalent SYSBPM menu functions.

The SYSBPM direct commands listed below can be entered in the Command line of any SYSBPM screen. To execute a SYSBPM direct command from any other command prompt or in batch mode, the direct command must be preceded by the keyword SYSBPM, for example: 

SYSBPM ADD BLACKLIST

An underlined portion of a SYSBPM command represents its minimum abbreviation. Parameter values that are required by a command are represented by letters in italics.

Command Parameters Function
+ none Scrolls one page down in a list.
- none Scrolls one page up in a list.
ADD BLACKLIST none Invokes the Maintain Blacklist screen described in Blacklist Maintenance.

DELETE ALL none Deletes all objects from the blacklist as described in Delete Object Set from Blacklist.
DELETE BUFFERPOOL

or

DELETE BP

 none Deletes all objects from the buffer pool only.
library-name
object-name dbid fnr 		Deletes the specified object(s) from the buffer pool only.

 none Invokes the function Buffer Pool Hash Table Statistics and displays the Hash Table Collisions screen.
DISPLAY HDIRECTORY library-name
object-name dbid fnr 		Invokes the Directory Information Hex screen that displays in hexadecimal format the directory information of an object.
DISPLAY HEX library-name
object-name dbid fnr 		Invokes the Hexadecimal Display screen that displays in hexadecimal format the source of an object.
DISPLAY LIST library-name

In contrast to the command DISPLAY CLIST, this command generates a statistics report that displays data about buffer pool objects at the beginning of the list.

DISPLAY LOAD none Invokes the Buffer Pool Load/Locate Statistics screen described in Buffer Pool Statistics.
DISPLAY PERFORMANCE none Invokes the Performance Hints screen with performance-related statistics of a Natural buffer pool and BP cache as described in Buffer Pool Statistics and BP Cache Statistics.
DISPLAY STATISTICS none Invokes the Buffer Pool Statistics menu described in Buffer Pool Statistics.
EDIT PRELOADLIST list-name Invokes the Edit Preload List screen described in Preload List Maintenance.
EDIT SET library-name set-name Invokes the Edit Object Set screen described in Blacklist Maintenance.
EXIT none Leaves the current function/screen and displays the previous screen.
FLIP none Switches the PF-key line: toggles between the display of PF1 to PF12 and PF13 to PF24.
GENERATE PRELOADLIST list-name gen-library Invokes the function Generate Preload List from Buffer Pool.
INITIALIZE none

or:
1, 2, 4, 8, 12, 16

Reinitializes the buffer pool and the BP cache. If no text record size is specified, the current text record size will be taken.

Only use this function if the Current Use Count (see Directory Information) is equal to 0 (see the warning below) or if the buffer pool has been destroyed.

Warning:
If you try to reinitialize the buffer pool while objects are being executed by active sessions in this buffer pool, the Confirm Initialization window appears with the Current Use Count for this buffer pool (not counting the SYSBPM user himself). If Current Use Count is not equal to 0 (zero) and you enter a Y to confirm the reinitialization of the buffer, the results of the active sessions are unpredictable and Natural can even abend.
INITIALIZE BP none

or:
1, 2, 4, 8, 12, 16

Reinitializes the buffer pool only. If no text record size is specified, the current text record size will be used.

See also the Warning above.

INITIALIZE BPC none BP cache required.

Reinitializes the BP cache only. The text record size of the BP cache is fixed (4 KB).

LAST none Displays the SYSBPM direct command entered most recently.
LIST PRELOADLIST list-name Invokes the List Preload Lists screen for the specified object as described in Preload List Maintenance.
