Disk Sorts
- Organization of this page
Overview
The Disk Sorts alarm monitors the percentage of all sort operations executed on disk using memory and disk I/O operations.
This alarm may occur when only PFM - RM for Oracle is manipulating the Oracle Database and no other applications are running. If this is the case, you can suppress this alarm from occurring by increasing the value of SORT_AREA_SIZE (or the value of SORT_AREA_RETAINED_SIZE, if specified). The guideline for this value is 204,800. After specifying this value, restart the Oracle Database to apply the new setting.
