如何编译无效对象

编译无效对象

1、查找无效对象：
SELECT object_name, object_type FROM dba_objects
WHERE status = 'INVALID';
2、编译无效对象：
手工编译：
ALTER PACKAGE pkg1 COMPILE REUSE SETTINGS;

使用PL/SQL Package编译 :
revalidate all invalid objects in the database, in parallel and in dependency order:
begin
   utl_recomp.recomp_parallel();
end;
/

revalidates the procedure  UPDATE_SALARY  in schema HR:
begin
   dbms_utility.validate('HR', 'UPDATE_SALARY', namespace=>1);
end;
/

revalidates the package body HR.ACCT_MGMT:
begin
   dbms_utility.validate('HR', 'ACCT_MGMT', namespace=>2);
end;
/
