Due to the sort performed by PFM - RM for Oracle, if you use the alarm table PFM RM Oracle Template Alarms MM.NN# provided by the monitoring template to perform monitoring, a Disk Sorts alarm may occur. If the error occurs, increase the value of the initial parameters SORT AREA SIZE and SORT AREA RETAINED SIZE of Oracle appropriately. When you set the new values, restart Oracle to enable the settings.
