There are several methods for maintaining database logs:
| Method | Use | Information |
|---|---|---|
| Teradata Viewpoint Monitored Systems portlet, Log Table Cleanup and Cleanup Schedule menus | Configure specific logs for clean up and specify the cleanup interval.

| Teradata Viewpoint, Performance Data Collection portlet | Archive log data to PDCR history tables and clean up log files. Choose either this or the previous method, since they both automatically clean up the Data Dictionary. | See Setting Up Automated PDCR Log Maintenance |
| Manually, using SQL and backup | Copy files and delete objects in the log older than a certain date. | See Deleting Old Log Data Manually from System Tables |
