Define LSR Buffer Pools

To define an LSR buffer pool, in the CA-L-Serv parameter data set, specify:

ADDPOOL nn (size,count)... STRNO(nnn)

nn

Specifies a number to the pool with nn. Specify a value from 1 to 15.

size

Specifies a buffer size in bytes. Specify one to four (size,count) pairs.

count

Specifies the number of buffers that CA-L-Serv allocates in that size (the minimum number is 3).

nnn

Optional. Specifies the nnn number of VSAM strings that are assigned to the buffer pool. The STRNO count specifies the maximum number of concurrent I/O requests against the buffer pool that VSAM is able to process. Specify a value from 3 to 255 (the default is 16).

Note: In multiple system environments, issue ADDPOOL commands only on the system where the host server is running.

For example, to allocate buffer pool 3 with eight 1,024-byte buffers and four 32,768-byte buffers, specify this command in the CA-L-Serv parameter data set:

ADDPOOL 3 (1024,8) (32768,4)
