Rebuilding the RPM database
The database that keeps track of your RPM (Red Hat Package Manager) installations can become corrupt. You should only perform this function when technical support advises you that it is the correct course of action.
To rebuild the RPM database:
Click on the Rebuild RPM Database link in the Software menu.
Click on the Ok button.
Note: This procedure may take 1-30 minutes, depending on the speed of your machine.
