Deactivating LOGONHERE support
By default, LOGONHERE support for the LOGON command is on; TSO/E users can reconnect to their
session even if no disconnection has been detected. LOGONHERE support makes it easier for users to
reconnect from a new terminal or after renewing their IP address. To disable this support, follow
these steps:
- Change the LOGONHERE parameter on the LOGON statement in the SYS1.PARMLIB member IKJTSOxx from the default LOGONHERE(ON) to LOGONHERE(OFF).
- Use the MVS™ SET IKJTSO=xx or TSO/E PARMLIB UPDATE(xx) command to update the system settings.
