ISAM Monitored data on ISAM pools

When the access method NK-ISAM is installed, the monitoring program for ISAM pools provides information on the performance of the ISAM buffer management facility. ISAM buffer management is aimed at reducing the physical I/O operations involved in accessing ISAM files. Using the information recorded in this monitoring program, the access behavior of this ISAM pool can be optimized by modifying the parameters of an ISAM pool, as required (for more details on the ISAM access method, please refer to the “DMS Macros” manual [2 (Related publications)]).

Up to 16 ISAM pools (defined via pool name, catalog ID and scope) and in addition the pool data of up to 16 ISAM files can be monitored.
