Question
Can an IBM CL/SUPERSESSION site connect to a UNIX® application?
Cause
Answer
CL/SUPERSESSION permits a single user to access multiple VTAM applications. While the CT/ENGINE base component it uses for communication is continuously being improved, the current architecture does not permit direct TELNET connections.
However, the current robust functionality can be exploited to provide TELNET client solution in one of two ways:
- TSO or another application capable of acting as a TELNET client can be used as a background host session. A virtual session, then, can be established with that host session. User profiles can be modified to maintain IP addresses or host names, a host session ID, and a logon navigation dialog.
- The LINK() dialog function can be coded to make the necessary EZASMI sockets calls. However, beyond this being a significant effort, this method is not recommended because it likely puts the MVS TCB that runs user tasks in a WAIT that can compromise the performance and availability of the address space. The LINK() dialog function is further described in the "CL/SUPERSESSION Dialog Language Reference Manual." General user exit conventions are described in the "CL/SUPERSESSION Customization Guide."
NOTE: It is IBM's intent to continue to support VTAM in z/OS Communications Server for the foreseeable future. Customers have a substantial investment in 3270 and SNA applications. IBM continues to support and enhance VTAM's capabilities while integrating it with new technologies. IBM has no plans at this time to discontinue SNA support in z/OS Communications Server.
