Hi Nenad,
Sys might be exempted from ORA-04036.
not be subjected to any of the actions described in this section. Instead,
if they are using the most untunable memory, they will periodically write a
brief summary of their PGA usage to a trace file.
I reproduced the error by running the procedure under a non-sys user. Sys
might be exempted from ORA-04036.
I had to put fill_memory at the end of the body to compile it under a
non-sys user. Under sys this wasn’t necessary. This might indicate that the
compiler makes two passes when compiling sys objects and only one pass for
non-sys.
With every mistake we learn something new. This time, the luck was double.
Best regards,
Nenad

Hi Mikhail,
It hasn’t worked for me on 19.8 (Linux) and 19.7 (Solaris x64).

Hi Nehad,
I slightly amended the package to raise an ORA-4036 in my 19c database:
https://gist.github.com/mvelikikh/3306c657ab43ea1a32304114dc4c84d2
Here is the call:
SQL> exec pkg.fill_memory
BEGIN pkg.fill_memory; END;
