Use the SAVSYS command or option 40 of the GO LICPGM menu with your job in a premastering state.
When you use the SAVSYS command in the premastering state, you write to tape a template version of
this structure with the label QCDIMLP. The pointer in the template
Preparing the distribution or premastering media
Creating the distribution or premastering media requires a dedicated system and both *SAVSYS and
*JOBCTL special authority.
If an error occurs while preparing the media, use the job log and history log to determine the error.
You may need to Consider compression and decompression of licensed programs if hard drive space is a
concern.
If the target site system is using automatic installation, you must create or change an installation profile or
use an IBM-supplied installation profile. Working with installation profiles contains information about
creating or changing an installation profile and using an
Considerations for compressing and decompressing licensed programs
IBM ships licensed programs in a compressed state to save disk space on the iSeries server. When you
install a compressed licensed program, it automatically and permanently decompresses if the system has
enough free disk space.
At least 250 MB of free disk space is needed if you are replacing a release using option 1 (Restore
Licensed Internal Code) on the Install Licensed Internal Code (LIC) menu. At least 1000 MB of free disk
space is needed if you are installing a release on a system that has been initialized using option 2 (Install
Licensed Internal Code and Initialize the System). The CL Programming
book has more information
on automatic decompression of objects. Automatic decompression of licensed programs does not affect
installation time.
Once started, automatic decompression stops if the system detects that there is not enough free storage
available (250 MB).
Notes:
1. Programs (*PGM), service programs (*SRVPGM), and modules (*MODULE) automatically and
permanently decompress the first time they are used.
2. The first time a compressed panel (*PNLGRP), menu (*MENU), printer file (*FILE with attribute PRTF),
or display file (*FILE with attribute DSPF) is used, it is temporarily decompressed. If such a temporarily
decompressed object is used five times or for more than two consecutive days on the same initial
program load (IPL), it is permanently decompressed.
Usually, an operation on a compressed object takes a little longer than if the object were decompressed. If
a very large compressed object decompressing, the system will send the message, ″Operation in
progress. Please wait″.
When creating distribution or premastering media, you may decide to do one of the following:
v Leave all the licensed programs that have high usage decompressed.
