Temporarily applied PTFs require a considerable amount of disk storage space. Do this only for products and temporarily applied PTFs that you have verified on your system.
When a new release is installed, the installation process overwrites the PTFs applied to the previous release. The PTFs for the previous release are no longer applied, but there might be associated objects that remain on the system and take up disk storage space. When you use Operational Assistant and choose to clean up system journals and system logs, PTF save files from previous releases are deleted from your system. However, for systems that have the System Manager for iSeries™ licensed program installed, the PTF save files are not deleted.
Notes:
- Apply fixes contains information on applying immediate PTFs temporarily or permanently.
- Do not permanently apply PTFs for those licensed programs that you do not plan to upgrade.
- If you have System Manager for iSeries licensed program (57xx-SM1) installed
on your system, use the instructions in the book System Manager Use
for managing PTFs on your system.
