Is the single socket listener still supported under CA GEN release 8.6?
CA GEN release 8.6
The CICS Sockets Server Listener (program TISRVLIS) was deprecated in CA Gen Release 8.5.
It is still supported in CA Gen 8.6, but will not be enhanced with any new functionality.
The CICS Multi Sockets Server Listener (program TISRVMSL) is the replacement product.
