Connecting to a remote system through the Interactive ISPF Gateway

Use this procedure to connect to a remote z/OS® system when the Interactive ISPF Gateway is enabled on the server.

The product client and server must be version 9.5 or later, and the Interactive ISPF Gateway must be enabled on the server. For more information about enabling the Interactive ISPF Gateway on the server, see zee.env, the environment configuration file in the Host Configuration Guide.
To minimize problems connecting to the remote system through the Interactive ISPF Gateway, observe these practices:
  • When you log on to TSO through the Interactive ISPF Gateway, do not specify a procedure that starts ISPF panel applications.
  • As with regular TSO logon through a 3270 session, TSO stores the logon data in your security TSO segment, replacing what was already there. This situation can result in unexpected logon values if you uses different values to log on to a TSO session through 3270.
  • If you use multiple Interactive ISPF Gateways simultaneously, or if you log on to TSO through 3270 and through the Interactive ISPF Gateway simultaneously, TSO and ISPF must be set up to allow multiple simultaneous logons.
  1. In the Remote Systems view, select a z/OS connection to a server that has the Interactive ISPF Gateway enabled.
  2. Right-click and select Connect.
  3. On the Enter Password window, type your user ID and password. Passwords are limited to 30 characters.
  4. To save your user ID and password, select the Save user ID and Save password checkboxes.
    Note: The Save password checkbox can be disabled. For more information, see #_RSE_JAVAOPTS="$_RSE_JAVAOPTS -DDENY_PASSWORD_SAVE in the related topics.
  5. Click OK. If the remote system is configured to secure the connection with encrypted communication, the Import Host Certificate window opens. This window opens the first time that you attempt to connect to a remote system secured with encrypted communication. Subsequent connections use the imported host certificate. When a remote system connection is secured, the Properties view for the MVS Files subsystem displays SSL Enabled.
  6. Click Finish to import the host certificate. The TSO Logon window opens. The fields on this window are populated with default values. For more information about the values you need to specify, see your systems administrator. These values, or any new values that you enter, are saved on the TSO Logon page of the Properties for TSO Commands window.
    Important: The procedure name you specify in the Procedure field cannot start an ISPF panel. If the procedure starts an ISPF panel, the logon request fails.

  7. Click OK. The connection is completed.
  8. If the remote system is configured for push-to-client, you might be prompted to accept configuration updates. For more information about updating configurations and preferences, see the related links.
