Puoi utilizzare SQL dinamico per interrompere la dipendenza:
CREATE OR REPLACE PROCEDURE proc_main AS
BEGIN
EXECUTE IMMEDIATE 'BEGIN proc_child1; END;';
EXECUTE IMMEDIATE 'BEGIN proc_child2; END;';
EXECUTE IMMEDIATE 'BEGIN proc_child3; END;';
proc_compile_invalids; -- This invokes
-- "alter procedure <procedure_name> compile"
-- statement for all the invalids.
END;
