The zOS Tab
When you work on a project, you might want to use resources that are on a mainframe machine. You can set up your remote connections and associate them to your project, by using the zOS option.
The zOS tab presents a list of all the z/OS® connections that are defined and you can modify the existing ones or create new connections.

To create a new z/OS connection, follow the steps:
- Go to the zOS tab in IBM® AD Build Configuration, right-click on the z/OS connection root and select Create zOS Connection. The Mainframe Access Point Connection window is displayed.
- Enter the name for the new z/OS connection, then click OK.
- The zOS Connection Setup dialog is displayed.Enter the host IP or host name, the port number, and the maximal number of concurrent threads in the corresponding fields, then click Test Connection to check the connection to the new Mainframe access point. If the parameters you entered are correct, a confirmation window is displayed. Starting with version 5.1.0.7, the Enable AT-TLS checkbox is available. With this checkbox, encrypted and non-encrypted connections can be supported at the same time. To create an encrypted connection, select this checkbox and follow the instructions in topic Enabling TLS Connection between IBM AD Build Client and IBM AD Connect for Mainframe.Note: An existing z/OS connection can be edited or deleted.
