After a thorough and comprehensive tuning review...a revised version is below..
create or replace procedure do_ddl(m_sql varchar2)
as
in_use exception ;
pragma exception_init(in_use, -54);
begin
while true loop
begin
execute immediate m_sql;
exit;
exception
when in_use then null;
-- when others then raise;
end;
dbms_lock.sleep(0.01);
end loop;
end;
/
