CICS® always builds a control block for LSR pool 1. CICS builds control blocks for other pools if either a LSR pool definition is installed, or a file definition at CICS initialization time has LSRPOOL= defined with the number of the pool.
VSAM local shared resources can be used in CICS systems that use VSAM.
See VSAM tuning: general objectives.
CICS uses the parameters provided in the LSR pool definition to build the LSR pool.
VSAM LSR can be monitored by means of response times, paging rates, and CICS LSRPOOL statistics. The CICS LSRPOOL statistics show string usage, data set activity, and buffer lookasides (see LSRpool statistics).
