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;
*
ERROR at line 1:
ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT
Here is the alert log:
