Hello Mr Snowy, Please refer to the following parameters, for values you need to cross check with SAP and hardware vendor(s) : zcsa/table_buffer_area em/initial_size_MB ztta/roll_area rdisp/PG_SHM rdisp/PG_MAXFS ipc/shm_psize_10 zcsa/db_max_buftab ipc/shm_psize_14---Delete ipc/shm_psize_18---Delete ipc/shm_psize_19---Delete ipc/shm_psize_30---Delete Hope this helps.
