This section helps
Scope
The scope of this section is to help you configure the SQL Server-based PMDB after you have installed install Precise. This is not a replacement of the content within Installation and Administration. The configuration recommendations help you to fine-tune the PMDB, which then results in faster and more efficient performance.

Be aware that the index and the table are unavailable during the rebuild.
Backing up the database and creating archiving
Use the Database Maintenance Plan function to create a backup plan for the database. Make sure that the SqlServer agent is automatically started at database startup.
- If you choose the simple recovery mode for the database (the transaction log can be deleted after a commit or checkpoint) , the recovery does not work to a point in time, but only to the backup time.
- If you choose a full recovery mode for the database, make sure you also backup the transaction log and shrink the database periodically , to stop the transaction log from growing infinitely.

If you do not create a backup, information is lost when you have a database crash and you cannot recover data . |
