Use DEFINE BUFFPOOL to define a buffer pool that is used for holding messages in main storage.

You can use the DISPLAY USAGE TYPE(PAGESET) command to display buffer pool information (see DISPLAY USAGE).

Synonym: DEF BP

DEFINE BUFFPOOL
 
                                 .-BUFFERS(1000)----.

                                 '-BUFFERS(integer)-'
 
 

 

Parameter descriptions

If this command is not issued, the default number of buffers is assumed. If more than one DEFINE BUFFPOOL command is issued for the same buffer pool, only the last one is actioned.

(buf-pool-id)

Buffer pool identifier. This is required.

This is an integer in the range zero through 15.

BUFFERS(integer)

The number of 4096-byte buffers to be used in this buffer pool. This is optional. The default number of buffers is 1000, and the minimum is 100. The maximum number of buffers for all the buffer pools is determined by the amount of storage available in the WebSphere MQ address space.

See the WebSphere MQ for z/OS Concepts and Planning Guide for guidance on the number of buffers you can define in each buffer pool.
