InterScan™ Messaging Security Appliance (IMSA) often needs to access its database. However, over time the database might become unstructured in a way that slows down database queries, which could affect IMSA performance. Trend Micro suggests configuring a database maintenance schedule to re-index database tables.
IMSA will analyze database tables daily at 2 AM and vacuum the database tables daily at 3 AM.
To set a maintenance schedule:
Choose Administration > Database Maintenance from the menu.
Select Re-index database tables.
Click one of the following to set the schedule frequency:
Weekly—Choose a day of the week and a time.
Monthly—Choose a day of the month and a time.
Click Save.
