Study Notes

Database Maintenance Overview

PME uses databases to store information like system configuration, data logs, and system event log messages.
Databases must be maintained to preserve performance, manage disk space, and prevent data loss in case of database failure.

Database Maintenance Operations

Database maintenance keeps the database operating at an optimal level of performance.
Over time, a database can become large and slow if not de-fragmented, trimmed, and optimized regularly.
Two methods for database maintenance:
- Using Database Manager for manual operations on Power Monitoring Expert databases.
- Using Windows Task Scheduler for automated operations like backup, maintenance, and trim.

Database Manager

Database Manager provides a console for manually performing operations on PME databases.
Operations include:
- Archive
- Export Registry Settings
- New ION_Data Database
- Trim
- Upgrade Database
Prerequisites:
- User needs to be a member of the sysadmin SQL Server role (set in SQL Server Management Studio)

Windows Task Scheduler

Task Scheduler can be used to configure scheduled jobs for automated operations like backup, maintenance, and trim.
Databases have preconfigured default times for these jobs (standalone systems only).
You can enable or disable these jobs using the Windows Task Scheduler.
Prerequisites:
- Password for the IONMaintenance account is needed to perform any Task Scheduler actions.

Key points to remember

Database maintenance involves manual and automated tasks to optimize database performance.
Database Manager helps maintain databases through periodic maintenance, backups, and archives.
