6 Troubleshooting
Troubleshooting should only be undertaken by specialists.
6.1 Database and network questions
Q: When I start the database server, the database displays the following error
message: "Database name already in use"
A:
Check that the database is already running on a PC connected to the
network.
You can do this by looking at the Task List.
Check that the command prompt for starting the database contains the IP
address of the PC.
Q:
How can I find the IP addresses in my system?
A:
Start the command prompt in Windows:
ipconfig
Make sure that not only the IP address, but also the subnet masks match
those in other systems.
Q:
How do I check the network connection between the two systems?
A:
Start the command prompt and enter the following:
ping 111.222.333.444
replacing 111.222.333.444 with the IP address of the remote system.
If there is no response, check the cables, the IP address and the associated
subnet mask.
Once Hotel Solution consists of more than one PC, the configuration value
two_or_more_pcs must be set to TRUE.
If you only have one PC, we recommend that you set this value to FALSE.
6.2 Room controller communication diagnostics
This section deals with the DGU driver and the associated console interface.
6.2.1 General introduction to the DGU driver
If the DGU Driver service has been started successfully, the DGU console interface will
open. It displays the DGU driver version and, after a successful connection to the
database, it reports on the DGU initialization of the individual rooms read from the
database.
The DGU drv waits for the database prior to initial connection to ensure that the
database service has already started upon reboot!
You are then prompted to press any key for access to the main menu.
