Connecting a Client to a Data Source
3. The ODBC client application sends a connection request to the MXCS server,
which is assigned by the Association Server. If the user information is not valid, the
connection is rejected.
4. When the ODBC client application disconnects, the MXCS server notifies the
Association Server that it is available for a new connection from other ODBC
clients and returns to the data source server pool.
An ODBC client application can connect to the default data source without creating an
MXCS SQL server data source.
