As the following figure shows, CSAs:
Invoke Open ClientConnect.
Specify the server connection.
Pass the SQL statements through Mainframe Client Connect and to the data source.
In this way, the CSA acts as a client to the local DBMS using Mainframe Client Connect. Because the CSA is a client, the functions you can perform with a CSA are roughly equivalent to functions you can perform with a client application on the LAN, such as ISQL. See Figure 1-2.
Figure 1-1: CSA processing overview
CSA can go directly to the LAN Server using TCP/IP (Gatewayless). See Figure 1-2.
