System prerequisites for the ISPF plug-in

This section describes the system setup actions required for using the ISPF task.

To use the ISPF task, a user should be an existing TSO/E user with a valid, non-expired password.

For each user of the ISPF task, you must ensure that the corresponding user ID:

Is authorized to TSO/E
Is authorized to the JES spool. This authorization allows the user to use various functions in TSO/E, such as the SUBMIT, STATUS, TRANSMIT, and RECEIVE commands, and to access the SYSOUT data sets through the command TSO/E OUTPUT command.
Has an OMVS segment defined, which allows for access to z/OSMF
Has a home directory defined, which is required for z/OSMF.

By default, the ISPF task is setup to use the logon procedure IKJACCNT, which is supplied by IBM®. A user can select to use a different logon procedure, as long as the user's logon procedure is properly configured for ISPF.
