Oracle’s documentation recommends to execute actualize_all in
order to purge old editions in the DB accumulated during previous patching
cycles.
There’s a problem with EBS version 12.2.4 that when running adop
phase=actualize_all you get an ORA-04045 errors during
recompilation/revalidation of .
You can try to manually recompile objects but all of them fail
with the same error. This is documented under bug 24489846.
Follow the instructions on the MOS note id 2187877.1.
I also recommend to open an SR as this bug is still open as of
May 2018.
Thanks,
Alfredo
