Create the procedure, then execute it in a decent client:

SELECT get_whole_database_ddl;

Ensure that your client doesn't truncate the output.

For example, DBeaver has a setting "Maximum text editor content length". Increase it.

SQL Developer actually needs to spool that to a file:

SET LONG 1000000000            -- allow very large output
SET LONGCHUNKSIZE 32767        -- size of each chunk
SET PAGESIZE 0                 -- suppress page headings
SET LINESIZE 32767             -- avoid wrapping

SPOOL C:\path\to\whole_db_ddl.sql
SELECT get_whole_database_ddl;
SPOOL OFF
