By default, after a user's terminal disconnects, the user's address space remains available for the period of time as defined by the RECONLIM parameter in SYS1.PARMLIB member TSOKEYxx. To reconnect while the address space is still available, users can use the RECONNECT operand of the LOGON command, and bypass the logon process. After the time limit expires, however, the address space is no longer available, and the user must reissue the LOGON command. You can change the amount of time during which a user can reconnect.

To prevent users from unnecessarily tying up available logons, you may want to reduce the amount of time users' address spaces remain available. Be careful, however, that you do not limit the time to a point where users do not have enough time available to reconnect. To limit the amount of time available for reconnecting, use the RECONLIM parameter in SYS1.PARMLIB member TSOKEYxx. For more information about the RECONLIM parameter, see .

You can write a logon pre-prompt exit to make it easier for users to reconnect after their terminals have been disconnected. For more information, see Writing a logon pre-prompt exit (IKJEFLD/IKJEFLD1).
