Thank you, but I guess I did not explain my issue clearly.
We have four Dell servers running SQL Anywhere on QNX4. That is not going to change.
What we are trying to install clients on either QNX6 or RH Linux to access the data that will still be running on the QNX4 servers.
Using some form of replication may be acceptable if the speed of data transfer is fast enough.
The data on the QNX6/RH Linux would be (mostly) for reporting.
