dbmssml.sql ordlib.sql

After an out of place upgrade from 11g to 19c I have found that the ORDIMLIBS points to the old home.

ORDIMLIBS    /u01/app/oracle/product/11.2.0.4/dbhome_1/lib/libordim11.so

Per document 2145739.1 I should re-run dbmssml.sql ordlib.sql. However, per the document it appears that the db should be in mount state; is that correct? Also in my 19c $ORACLE_HOME/rdbms/admin directory there is no dbmssml.sql. Furthermore when I look at ordlib.sql the EXECUTE IMMEDIATE ('CREATE OR REPLACE LIBRARY ORDIMLIBS AS ''' is empty. From the note it's not clear to me if I should be updating the code with the library or if it will get updated via the code itself.
