Applying PTFs without an IPL

Beginning in V3R1, PTFs are built to produce PTFs without requiring IPLs to apply them whenever possible. PTFs that can be applied immediately have additional activation steps, which are described in the cover letter. Updateable and non-updateable actions exist.

Updateable action PTFs are shipped with an action-exit program to verify the actions required to activate the PTF. The action-exit program is called by the DSPPTF command to list the actions necessary and verify whether the actions are completed. The exit program is called when the details for the PTF are shown using option 5 on the DSPPTF status panel or when you specify SELECT(*ACTRQD) on the DSPPTF command. The status of the PTF is updated if the actions are complete. The status changes from Temporarily applied—PND to Temporarily applied after the required actions are complete.Non-updateable action required PTFs do not have exit programs to verify that the actions have been done. These PTFs remain in a Temporarily applied—ACN status until the next IPL when the status changes to Temporarily applied.
