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 (TYPE=NAT), see TYPE - Type of Buffer Pool in the BPI - Buffer Pool Initialization documentation.

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.

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

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.
