Connection Checklist
Question:
What kinds of things can I check for every time I deploy
a multi-tier application?
Answer:
Note: This list is not intended to be inclusive, but covers
some of the most often missed items.
On the Server
- Export all dataset interfaces by right clicking the dataset
components and selecting the "Export from .." context menu option.
- Rebuild the application.
- If you're running TCP/IP as the transport layer, run
\bin\Scktsrvr.exe on the server.
On the Client
1. If possible, verify your connectivity setup. If you're
using TCP/IP, you can ping the server from the client.
2. On the TRemoteServer or TMidasConnection:
- Verify the ComputerName.
- If the application is on another computer, verify the GUID.
- If local, verify the ServerName.
- Verify that you can set Connected = true.
- If using TMidasConnection, check that your ConnectType matches
the connectivity you have set up (i.e. ctSockets for TCP/IP, etc).
3. Verify that each TClientDataSet ProviderName and
RemoteServer properties are set.
Also, check that you have needed files on both client and
server and that they are registered.
