Runtime management tasks for the SFDB repository

Most interactions with the SFDB repository are handled automatically by SFDB code. Administrators only need to handle SFDB backup and restore activities and to monitor the hard disk space usage of the repository. A configuration file /etc/vx/vxdbed/admin.properties is created during installation to record the file system and volume used for the SFDB repository. The VxDBMS server starts automatically after a system reboot via rc files.
