Re: Script to overcome ORA-54 during DDL

Connor McDonald


After a thorough and comprehensive tuning review...a revised version is below..

create or replace procedure do_ddl(m_sql varchar2)
in_use exception ;
pragma exception_init(in_use, -54);
while true loop
 execute immediate m_sql;
 when in_use then null;
--  when others then raise;
end loop;
