Disconnect on session error

The DISCONNECTABLE option on either the ALLOWAPPL or RESTRICTAPPL statement determines what type of session termination to send to the host VTAM® application when Telnet initiates session termination. If DISCONNECTABLE is coded, Telnet issues a TERMSESS UNBIND(0F). Otherwise, Telnet issues a TERMSESS UNCOND. For example, when DISCONNECTABLE is coded for the TSO application, an unexpected connection loss results in an UNBIND(0F) being sent to TSO putting it in a reconnectable state. The DISCONNECTABLE parameter has no effect on a session ended normally by the user logging off the session. The QSESSION parameter can be coded with DISCONNECTABLE on either statement.
