Determining what unused parts of products to delete

You might be able to delete some optional parts of licensed programs to give you more storage.

Depending on your business needs, you might be able to delete some of the optional parts of the licensed programs that are shown in Table 2. (Table 2 shows V5R4 product identifiers, but the information in the table applies to deleting unwanted parts either before or after installing the new release of software.) For example, you can delete the licensed programs for any iSeries™ Access Family clients that you do not use. Deleting unwanted licensed programs or optional parts will give you more storage for your business needs.

Before you delete anything, read the following:

If you do not have the original or a current copy of i5/OS™ software distribution media, make sure that you first save the affected licensed program. Type GO LICPGM on the i5/OS control language (CL) command line and select option 13 (Save licensed programs). You will need extra tapes for this save operation. To save these licensed programs to tape can take several hours. At a later time, if you need any of the licensed programs or deleted optional parts, you can install them from these tapes. To install them, use GO LICPGM and select option 11 (Install licensed programs).
System backup tapes come with some systems. These backup tapes are not the same as software distribution media. While you can use software distribution media to reinstall individual licensed programs or optional parts, you cannot use system backup tapes. If you cannot locate or your system did not come with the original installation media, you must save the licensed programs and optional parts before you delete them. You will need the saved copy, if you need to restore the licensed programs or optional parts at a future time.

Use Table 2, the Software reference topics (Installation notes about the i5/OS release and Installation notes about other licensed programs), and the keys in the following table to help you determine which programs or optional parts you might want to delete.
