scdbufgrp (Specify message-storing buffer pool to be shared)

Format

{{scdbufgrp -g schedule-buffer-group-name
             [-n number-of-message-storing-buffer-cells]
             [-l length-of-a-message-storing-buffer-cell]}}

Function

A schedule buffer group is a collection of user servers that share a single message-storing buffer pool.

In the schedule service definition, specify the message-storing buffer pool to be created for each schedule buffer group.

Option

-g schedule-buffer-group-name~<1-to-8-character identifier>

Specify the name of the schedule buffer group that use a single message-storing buffer pool.

The schedule buffer group name must be unique in the node. If the same schedule buffer group name is specified more than once, an error occurs.

-n number-of-message-storing-buffer-cells~<unsigned integer> ((1-61440)) <<16>>

Specify the number of cells that configure the message-storing buffer pool to be shared.

-l length-of-a-message-storing-buffer-cell~<unsigned integer> ((512-31457280)) <<512>> (units: bytes)

Specify the length of a cell which is an element of the message-storing buffer pool to be shared.

Specify an integer multiple of 8 in this operand. If the specified value is not an integer multiple of 8, the value is rounded up to an integer multiple of 8.

The relationship among the length of the message-storing buffer pool, the number of message-storing buffer cells, and the length of a message-storing buffer cell is:

Length of the message-storing buffer pool=

Length of a message-storing buffer cell x Number of message-storing buffer cells

The maximum length of the buffer pool that can be reserved as the message-storing buffer pool is 31,457,280 bytes. If the result of Length of a message-storing buffer cell x Number of message-storing buffer cells exceeds this value, an error occurs.
