Oracle compiled user Invalid object

When migrating data using the Impdp/imp tool, warnings for invalid objects are often prompted and need to be handled as follows.

1. Querying invalid objects for a specified user

Su–oracle

Sqlplus/as SYSDBA

Sql> Select Owner,object_name,replace (object_type, ",") Object_type,to_char (created, ' Yyyy-mm-dd ') as Created,to _char (last_ddl_time, ' yyyy-mm-dd ') as Last_ddl_time,status from dba_objects where status= ' INVALID ' and owner= ' HKJJW ';
OWNER object_name object_type CREATED last_ddl_t STATUS
---------- ------------------------------ --------------- ---------- ---------- -------
HKJJW func_return_py FUNCTION 2013-08-02 2013-08-02 INVALID
HKJJW monitoring_flow_parallel_view VIEW 2013-08-02 2013-08-02 INVALID
HKJJW TEST VIEW 2013-08-02 2013-08-02 INVALID

Specifies that an invalid object is queried for a user.

Sql> SELECT * from dba_objects where status<> ' VALID ' and owner= ' HKJJW ';

2. Manually perform the compilation or

ALTER FUNCTION HKJJW. Func_return_py COMPILE;
ALTER VIEW HKJJW. Monitoring_flow_parallel_view COMPILE;
ALTER VIEW HKJJW. TEST COMPILE;

If it is index, it needs to be rebuilt.
Alter index INDEX_NAME rebuild;

If the package body
Alter package dbms_cube compile body;

3. Automatically generate compiled invalid object SQL1) count the number of invalid objects for the current user:

Sql> Select Owner,object_type,status,count (*) from dba_objects where status= ' INVALID ' GROUP by Owner,object_type, Status order by Owner,object_type;

OWNER object_type STATUS COUNT (*)
------------------------------ ------------------- ------- ----------
Hnadev_group FUNCTION INVALID 1
Hnadev_group Package BODY INVALID 35
Hnadev_group VIEW INVALID 7

2) Generate compiled invalid object sql

sql> select ' ALTER ' | | object_type | |  "| | OWNER | | '. ' | | object_name | | ' COMPILE; ' from dba_objects where status = ' INVALID ' and object_type in (' Package ', ' Package BODY ', ' FUNCTION ', ' PROCEDURE ', ' TRIGGER ', ' VIEW ');

' ALTER ' | | object_type| | ' | | owner| | '. ' | | object_name| | ' COMPILE; '
----------------------------------------------------------------------
ALTER VIEW Hnadev_group. V_e_t_feemonth_cal COMPILE;
ALTER VIEW Hnadev_group. V_e_t_feemonth COMPILE;
ALTER VIEW Hnadev_group. V_e_z_bill_stay_group COMPILE;
Slightly...
Manually perform the compilation execution directly by copying the above SQL statement.

4. You can also manually compile under Oracle users in the following ways

# su-oracle
$ sqlplus/as SYSDBA
sql> @ $ORACLE _home/rdbms/admin/utlrp.sql
