Manual Switch of Data Source

If there are more servers registered in the database than are actually running it might be the case that there is a server within the HA network which did not reconnect to the productive database.

In this case switch over the data source manually from the updatedb to the productive database.

To avoid this, check the server list at the beginning of the update.

The database schema will also be renewed the first time an updated server connects to the productive database. Afterwards, all other servers within the network can be switched over to this database.
