Defining a connection
A connection is
defined whenever you plan to use a connection
client in your network. The configuration holds the parameters how this
connection client should behave.
Connections can be defined in the tree-view
section of the screen under 'database connections'.
Use right mouse button, Edit, or
buttons to create new, edit or delete connections.
Configuring a connection is done in 3 parts:
After selecting New... or properties you get
the properties screen.
- Connection name:
the name you give to this connection (max. 50 characters)
- Connection type: see connection
type specific setup
- Control file: each client is
working with an MS-Access or Interbase oriented control file in which
the client is buffering the transactions, logging and keeps the client
specific configuration in case the dispatcher is not reachable at startup
of the client. You can specify the name of this control file here. If
you don't the system will use the connection name to define the control
file. You also need to know:
- When the client is started for the
first time, it is PRODBX who will create and install the control
- Do not modify anything in a control
- At startup of a client, the client
will check the registry if the control file was installed before.
The key is: HKEY_LOCAL_MACHINE/SOFTWARE/Promes/Prodbx/ConnectionClient/
<MyConnection>/AccessFilename. If this entry does not exist,
the client will ask the dispatcher to create a control file for
him. This implies that when your control file would be corrupted,
you can trick the system to create a new one by deleting this registry
- Clients can share a control file,
but is not recommended. Be careful when you copy connections.
- Client OS Type: (Display only)
At startup of a client, the client determines and reports the platform
it is running on. This platform can be NT (2000 or XP) or 98 (Me) oriented.
- Client Machine Name: (Display
only) At startup of a client, the client will report the machine name
to the dispatcher. This enables the dispatcher to communicate with the
The connection type listbox contains the
possible clients of your version of PRODBX. When selecting one of these your
setup screen will be extended with extra parameters specific to the connection
type selected. Follow the links to have more explanation on the various types:
