Each index number from 1 to 19 corresponds to the block size number. Example: PGDBR(8) = the number of times a block of 8 pages was read. For index number 20, this is the number of times a block of 20 or more pages was read. 100 64 Character 80 STOBPG_PGDBM_TBL 100 64 Unsigned 4 STOBPG_PGDBM(1:20) Number of times a block of the corresponding size was migrated. Each index number from 1 to 19 corresponds to the block size by a factor of 2. Example: PGDBM(1) = the number of times a block of 1 or 2 pages was migrated. PGDBM(6) = the number of times a block of 11 or 12 pages was migrated. For index number 20, this is the number of times a block of 39 or more pages was migrated. 180 B4 Character 80 STOBPG_PGDBS_TBL 180 B4 Unsigned 4 STOBPG_PGDBS(1:20) Number of times a block of the corresponding size was written.
