With the implementation of the Distributed Relational Database Architecture (DRDA) protocol, you can use ISQL to access data on remote DRDA application servers that support the DRDA protocol and on which ISQL is loaded. If you plan to use ISQL to access data on a remote DRDA application server, you should check with your System Administrator to see whether your application requester and the remote DRDA application server are set up for access using the DRDA protocol.
