- Notes:
-
-
Due to the sort performed by PFM - Agent for Oracle, if you use the alarm table PFM 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.
-
Due to the table scan performed by PFM - Agent for Oracle, if you use the alarm table PFM Oracle Template Alarms MM.NN# provided by the monitoring template to perform monitoring while only PFM - Agent for Oracle is manipulating the database, a Full Table Scans alarm may occur.
-
When PFM - Agent for Oracle does not connect to the monitoring target Oracle, PFM - Agent for Oracle does not detect any alarms except Server Status.
