Work with Licensed Internal Code

This option applies PTFs, removes PTFs, or makes PTFs permanent to the system Licensed Internal Code from removable media when the operating system is not available.

It also allows you to rebuild the Licensed Internal Code, display the Licensed Internal Code information and PTFs, and display free space. Select this option from the Use Dedicated Service Tools (DST) display. For more information on Licensed Internal Code fixes and PTFs, see Fixes and cumulative PTF packages and the system operation information.

Licensed Internal Code general information

There can be two versions of some Licensed Internal Code modules on the load-source disk unit. The IPL type (A or B) determines which version of the modules your system uses. When the system is running on a type A IPL, it uses the original, permanent version. When a Licensed Internal Code fix, or program temporary fix (PTF) is temporarily applied, the system creates a second version of the module. The system uses this second version when it is running on a type B IPL.

When the PTF is permanently applied, the side B of the Licensed Internal Code replaces the original side A version of the Licensed Internal Code module. The system will then use the PTF version of the Licensed Internal Code module (which is now permanent) when running on a type A IPL.

For PTFs to be activated on each partition, they must be separately applied to each partition.

To apply a PTF that currently has an earlier version applied temporarily on the system, perform an IPL of the system from the B side (type B IPL). Then load and apply the PTF. The existing temporarily applied PTF automatically becomes permanent as the new PTF is loaded. If you do not want the existing temporarily applied PTF to become permanent, remove it manually.

If you perform the IPL on the B side when you apply PTFs to Licensed Internal Code, the system applies the PTFs to the active copy of the Licensed Internal Code.

To run the system with the PTFs, you must perform an IPL. For normal operations, use type B IPL. Use type A IPL when the B side is not available or when you want to remove a PTF.

Note: During an installation or upgrade, a type A IPL will also be used.

Options and function keys

  • Apply fixes

    This option places the fixes into the Licensed Internal Code from removable media. These PTFs are placed in the inactive (change) copy of the Licensed Internal Code.

    Note: There are two copies of some Licensed Internal Code on the load-source disk unit. It is the IPL type (A or B) that selects the Licensed Internal Code level with which your system will run.
  • Rebuild Licensed Internal Code

    This option allows you to rebuild the Licensed Internal Code.

  • Display Licensed Internal Code
    This option allows you to display the following:
    • Replaceable unit information (code or object modules)
    • Fix information
    • Product information
    The Fix information option allows you to display the status of the Licensed Internal Code fix (if it is permanently or temporarily applied). For more information on displaying fixes, see Displaying Licensed Internal Code fixes.
  • Work with free space

    This option displays the space available for storing new modules on the system and allows you to combine the space that is used.

  • Remove fixes

    To remove Licensed Internal Code fixes, if the PTF is a delayed PTF, the system must be running on the copy without the changes (type A IPL). Removing these changes causes the system to load the primary copy over the changes in the changed copy of Licensed Internal Code.

    Immediate Licensed Internal Code PTFs can be removed while running a type B IPL.

  • Make fixes permanent

    To make Licensed Internal Code fixes permanent, the system must be running on the copy with the changes. When these changes are made permanent, they are loaded into the primary copy of the Licensed Internal Code.

  • Display status (F6)

    Press the F6 function key on the Work with Licensed Internal Code display to view the history log.

For more information on PTFs, see Displaying Licensed Internal Code fixes and the system operation information.
