How to find Invalid Objects and Compile in Oracle

Finding Invalid Objects and Compiling

Objects that requires recompilation are
----------------------------------------------------
VIEW, SYNONYM, PUBLIC SYNONYM, PROCEDURE, FUNCTION, PACKAGE, PACKAGE BODY, TRIGGER, UNDEFINED , JAVA CLASS, TYPE, TYPE BODY

Find Invalid Objects
---------------------------
set pages 50000 lines 32767
select OWNER, OBJECT_TYPE, COUNT(*) FROM DBA_OBJECTS WHERE STATUS = 'INVALID' and OWNER in ('&OWNER') GROUP BY OWNER, OBJECT_TYPE ORDER BY OBJECT_TYPE;

SPOOL The Invalids list
---------------------------
spool generate_invalids.lst

set pages 50000 lines 32767
col owner format a15
col object_type format a20
col object_name format a30
select owner, object_name, object_type,status,created,last_ddl_time from dba_objects where status = 'INVALID' and owner in ('&owner') order by object_type, object_name desc
/

spool off


Recompile Invalid Objects
-----------------------------------
spool recompile_invalids.lst

select 'alter '||decode(object_type,'PACKAGE BODY','PACKAGE',object_type) || ' ' ||owner|| '."'||object_name||'" '||decode(object_type,'PACKAGE BODY','COMPILE BODY','compile')|| ' ; '
from dba_objects where object_type in ('PACKAGE','PACKAGE BODY','PROCEDURE','VIEW', 'TRIGGER','FUNCTION','SYNONYM') and status='INVALID' and owner in ('&owner')

/
spool off

@recompile_invalids.lst

Validation
----------
set pages 50000 lines 32767
col owner format a15
col object_type format a20
col object_name format a30
select owner, object_name, object_type,status,created,last_ddl_time from dba_objects where owner in ('&owner') and trunc(last_ddl_time) = trunc(sysdate) order by object_type, object_name
/

exit
