Cannot create file dsn with Pervasive 8

We just upgraded from Pervasive 7.

Have many Excel files linked to Pervasive via MsQuery using a File DSN.

On the workstatation the ODBC interface looks different for setting up a File DSN connecting via Pervasive ODBC.

In the advanced parameters we tried doing nothing extra, and also specfying the server and database.

We have not been able to create a File dsn no matter what.

We have been able to create a user dsn which works fine.

We have always avoided File DSNs, as they have been somewhat unstable, and they do not work very well (as you have observed).

Your best bet is to create one System DSN as a Pervasive Client DSN on each workstation, pointing to the Pervasive Engine DSN on the server.  This works VERY well, the only drawback being that you must go to each workstation and create the DSN.  If the extra workload is the problem, there are ways two solutions:
1) Automate the DSN creation.  You can do this via:
  a) Registry imports
  b) Writing a standard MS/ODBC application
  c) Writing a Pervasive DTI/DTO application
2) Use a DSN-less connection.  Instead of specifying the File DSN, have the application provide the needed Connection String to go right to the server.

IN essence, the File DSN is only a tool for your users so they will not need to learn the ODBC Administrator. The information entered in a File DSN is the same general information that would be entered when creating a User or System DSN in the ODBC/32 Administrator.  You can try extract the information from a properly-created System DSN's registry settings & see if that works for you.

One other question -- you HAVE updated the client software on each workstation, right?  You cannot use the PSQL7 client to connect to PSQLV8.

Bill,

Its not a big issue to recreate the DSN on the workstations.  I do believe using a System DSN gives the most scope.

The problem is we have a number of Excel Documents referencing the the Btrieve data via MS Query.

Some of these spreadsheets were created using a File DSN as the source.

Without the File DSN on the workstation, the Excel documents will not work.

That is why we need to recreate the File DSN on the Workstation.

When we try to do this we are told that the DSN is "non-verified".  When we try to edit is we get a login prompt for Name and UserName.  We enter the correct info but then get another error message.

My question is: it is not possible to create a File DSN with Pervasive 8?  If it is, do we need to enter advanced info in the configuration such as datbase and server?  In doing that, what is the correct syntax?

They do work, but it can be a bear to set them up.  Here's one that worked on my workstation, connecting to a server named BWING and talking with an Engine DSN on that server called DEMODATA:

[ODBC]
DRIVER=Pervasive ODBC Client Interface
ServerDSN=DEMODATA
ServerName=BWING.1583
TCPPort=1583
ArrayBufferSize=8
ArrayFetchOn=1
TransportHint=TCP:SPX

If you are using SPX only, then remove the "TCP:" from the transport hint.  If you need security enabled, you may need to add UID and PWD entries.  See the ODBC driver information in the Pervasive manual for more details on optional connection string entries.
