You can use Sybase Central or an ALTER SERVER statement to modify the attributes of a server. These changes do not take effect until the next connection to the remote server.
You must have RESOURCE authority to alter a server.
Connect to the host database from Sybase Central.
Open the Remote Servers folder for that database.
Select the remote server, and then choose File > Properties.
Configure the various remote server properties, and then click OK.
Connect to the host database from Interactive SQL.
Execute an ALTER SERVER statement.
The following statement changes the server class of the server named RemoteASE to aseodbc. In this example, the Data Source Name for the server is RemoteASE.
ALTER SERVER RemoteASE CLASS 'aseodbc';
The ALTER SERVER statement can also be used to enable or disable a server's known capabilities. See ALTER SERVER statement.
