Create or specify an IODF

Create or specify an IODF

You specify the name of the IODF that you want to use on the Primary Task Selection panel. The first time you use the dialog, HCD puts the default name SYS1.IODF00.WORK in the IODF name field (see Figure 29). You can type over this name to specify the name you want to use.

If you specify an IODF name that does not exist, HCD assumes that you intend to create a new IODF and displays a panel to let you specify the required attributes. HCD then creates and automatically catalogs the IODF.

  • Volume serial number (of the data volume the IODF will reside on)

    This entry is ignored if your system is managed by SMS, otherwise it is mandatory.

  • Space allocation

    The online HELP gives advice on how much space to allocate. If you run out of space while working with an IODF, you can use the Copy IODF task to copy the IODF to a larger data set.

  • Activity logging

    You have to decide now whether you want HCD to maintain an activity log for the IODF; you cannot specify it later. If you want to use an activity log, your system must have Program Development Facility (PDF) installed.

  • Multi-user access

    Specify whether or not you want to enable the IODF for multi-user access.

  • Description

    Here you may enter any useful additional information concerning the IODF, for example, the system it applies to, a special purpose of the IODF, or the author.

The IODF remains in effect throughout all tasks of your current session and later HCD sessions, until you change it.
