ORA-39082 ".... created with compilation warnings" while Importing

ORA-39082   generally  occur during  the  import . The error  message  states that  the  object in  the  SQL statement  following  this  error was  created with  compilation errors. If  this  error  occurred  for a  view,  it  is  possible  that  the base  table of  the view  was  missing . Here  is  an scenario  of  ora-39082 error ....

All the above error ORA-30082 is a warning . This error occurs due to improper or re-order the sequence of importing the objects or due to the dependency on others objects . For example  , in above case data pump import create procedures before views, if our procedure have dependency on views then we will have the ORA-39082 compilation errors . There are various ways to solve this issues . 

1.)  Run  utlrp.sql  to recompile all invalid objects within the database after the import is complete. This script is in the $ORACLE_HOME\rdbms\admin  directory or alternatively we can use the built-in  DBMS_RECOMP package . This will usually clean up all the invalid objects. utlrp.sql  will compile objects in the database across schemas. In  case of  Re-mapping objects from one schema to another and utlrp.sql  won't be able to compile them .

2.) After the import is completed, recompile the every errors . This is useful when you have few errors. The below command are used to recompile the objects as 

SQL> ALTER PACKAGE <SchemaName>.<PackageName> COMPILE;

SQL> ALTER PACKAGE <SchemaName>.<PackageName> COMPILE BODY;

SQL> ALTER PROCEDURE my_procedure COMPILE;

SQL> ALTER FUNCTION my_function COMPILE;

SQL> ALTER TRIGGER my_trigger COMPILE;

SQL> ALTER VIEW my_view COMPILE;

SQL> EXEC DBMS_UTILITY.compile_schema(schema => 'shaik9sep11g') ; or 

SQL> EXEC UTL_RECOMP.recomp_serial('shaik9sep11g') ;

In case of synonym, we need to recreate the synonym.

3.) Use SQLFILE option from impdp to generate the DDL from the export dump and replace the schema name globally , edit and execute the script from sqlplus. This should resolve most of the errors. If we still have errors, proceed  with utlrp.sql. This is the one of good option to deal with this type of error .

4.) There are Bugs which return similar error during import( i.e, impdp). Check metalink  ORA-39082 When Importing Wrapped Procedures [ID 460267.1]
