2. DBMS_UTILITY
3. UTL_RECOMP
4. utlrp.sql
5. Manually Recompile
DBMS_DDL.ALTER_COMPILE
Syntax: -
exec dbms_ddl.alter_compile ( type , schema, name);
Type : Must be either PROCEDURE, FUNCTION, PACKAGE, PACKAGE BODY or TRIGGER.
Schema : Database Username
Name : Objects name
Example: -
SQL> exec dbms_ddl.alter_compile ('PROCEDURE','SCOTT','TEST');
PL/SQL procedure successfully completed.
DBMS_UTILITY.COMPILE_SCHEMA
Syntax: -
exec dbms_utility.compile_schema ( schema,compile all)
Schema : Database Username
Compile All : Object type ( procedure, function, packages,trigger)
Example: -
SQL> exec dbms_utility.compile_schema('SCOTT');
PL/SQL procedure successfully completed.
UTL_RECOMP
Syntax: -
exec UTL_RECOMP.RECOMP_SERIAL ();
Example: -
SQL> Exec UTL_RECOMP.RECOMP_SERIAL ();
PL/SQL procedure successfully completed.
Note: -Required SYS user to run this package.
UTLRP.SQL scripts
Located: $ORACLE_HOME/rdbms/admin
Example: -
SQL> @c:\oracle\product\10.1.0\db_1\rdbms\admin\UTLRP.SQL
TIMESTAMP
-----------------------------------------------------------------------
COMP_TIMESTAMP UTLRP_BGN 2007-08-04 12:47:21
PL/SQL procedure successfully completed.
TIMESTAMP
-----------------------------------------------------------------------
COMP_TIMESTAMP UTLRP_END 2007-08-04 12:47:26
PL/SQL procedure successfully completed.
Note: Required SYS user to run this script.
Recommended: -After upgrade or migrate database.
Best Approach is manually recompiling all Invalid Objects
Spool recompile.sql
Select ‘alter ‘object_type’ ’object_name’ compile;’
From user_objects
Where status <> ‘VALID’
And object_type IN (‘VIEW’,’SYNONYM’,
‘PROCEDURE’,’FUNCTION’,
‘PACKAGE’,’TRIGGER’);
Spool off
@recompile.sql
Note: VIEW,SYNONYM,PROCEDURE,PACKAGE,FUNCTION,TRIGGER
Spool pkg_body.sql
Select ‘alter package ’object_name’ compile body;’
From user_objects
where status <> ‘VALID’
And object_type = ‘PACKAGE BODY’;
Spool off
@pkg_body.sql
Spool undefined.sql
select ‘alter materizlized view ’object_name’ compile;’
From user_objects
where status <> ‘VALID’
And object_type =‘UNDEFINED’;
Spool off
@undefined.sql
Spool javaclass.sql
Select ‘alter java class ’object_name’ resolve;’
from user_objects
where status <> ‘VALID’
And object_type =‘JAVA CLASS’;
Spool off
@javaclass.sql
Spool typebody.sql
Select ‘alter type ‘object_name’ compile body;’
From user_objects
where status <> ‘VALID’
And object_type =‘TYPE BODY’;
Spool off
@typebody.sql
Spool public_synonym.sql
Select ‘alter public synonym ‘object_name’ compile;’
From user_objects
Where status <> ‘VALID’
And owner = ‘PUBLIC’
And object_type = ‘SYNONYM’;
Spool off
@public_synonym.sql

Simple query for compelling all objects in a database: - SELECT 'alter '||decode(object_type,'PACKAGE BODY','PACKAGE',object_type) ||' '||owner||
'."'||object_name||'" '||decode(object_type,'PACKAGE BODY','COMPILE BODY','COMPILE')||';'
FROM all_objects WHERE owner like '%'
AND owner not in ('SYS', 'SYSTEM')
AND object_type IN ('PACKAGE','PACKAGE BODY','VIEW','PROCEDURE','TRIGGER','FUNCTION')
AND status='INVALID';
