Symptoms

The example below is based on the directory object my\_dir that refers to an existing directory on the server where the Oracle RDBMS is installed. Example:

Windows: CONNECT system/manager

CREATE OR REPLACE DIRECTORY my\_dir AS 'D:\\export';

GRANT read, write ON DIRECTORY my\_dir TO public;

Unix: CONNECT system/manager

CREATE OR REPLACE DIRECTORY my\_dir AS '/home/users/export';

GRANT read, write ON DIRECTORY my\_dir TO public;

A schema that owns object types needs to be duplicated from schema U1 to schema U2 in the same database. Example:

CONNECT system/manager

CREATE USER u1 IDENTIFIED BY u1 DEFAULT TABLESPACE users;

CREATE USER u2 IDENTIFIED BY u2 DEFAULT TABLESPACE users;

ALTER USER u1 QUOTA UNLIMITED ON users;

ALTER USER u2 QUOTA UNLIMITED ON users;

GRANT create session, create table, create type TO u1;

GRANT create session, create table, create type TO u2;

CONNECT u1/u1

CREATE TYPE my\_coltype AS OBJECT (nr NUMBER, txt VARCHAR2(10))

CREATE TYPE my\_tabtype AS OBJECT (nr NUMBER, txt VARCHAR2(10))

CREATE TABLE my\_reltab (nr NUMBER, col1 my\_coltype);

CREATE TABLE my\_objtab OF my\_tabtype;

INSERT INTO my\_reltab VALUES (1, my\_coltype(1, 'Line 1'));

INSERT INTO my\_objtab VALUES (1, 'Line 1');

COMMIT;

The schema U1 can be exported successfully. E.g.:

expdp system/manager DIRECTORY=my\_dir DUMPFILE=expdp\_u1.dmp LOGFILE=expdp\_u1.log SCHEMAS=u1

The import into schema U2 fails though with the following errors:

impdp system/manager DIRECTORY=my\_dir DUMPFILE=expdp\_u1.dmp LOGFILE=impdp\_u1.log

REMAP\_SCHEMA=u1:u2...

Import terminated successfully with warnings.

...Cause

The object types MY\_COLTYPE and MY\_TABTYPE already exist in the source schema U1. When the types are exported, we also export the object\_identifier (OID) of the types. Within the current archictecture, the object-identifier needs to be unique in the database.

During import (into the same database), we try to create the same object types in the U2 schema. As the OID of the types already exists in the source schema U1, the types cannot be created in the target schema U2. Import will fail due to:

ORA-02304: invalid object identifier literal

Solution

1. In Oracle10g Release 1 (10.1.0.x.y), you can pre-create the object types and the tables in the target schema, and run an import with the TABLE\_EXISTS\_ACTION parameter. Example:

CONNECT u2/u2

CREATE TYPE my\_coltype AS OBJECT (nr NUMBER, txt VARCHAR2(10))

CREATE TYPE my\_tabtype AS OBJECT (nr NUMBER, txt VARCHAR2(10))

CREATE TABLE my\_reltab (nr NUMBER, col1 my\_coltype);

CREATE TABLE my\_objtab OF my\_tabtype;

impdp system/manager DIRECTORY=my\_dir DUMPFILE=expdp\_u1.dmp LOGFILE=impdp\_u1.log

REMAP\_SCHEMA=u1:u2 TABLE\_EXISTS\_ACTION=append...

Job "SYSTEM"."SYS\_IMPORT\_FULL\_01" completed with 3 error(s) at 13:13

Note that beginning with Oracle10g Release 2, this will fail for the table MY\_RELTAB with the errors:

...

2. Beginning with Oracle10g Release 2 (10.2.0.x.y), there is no need to pre-create the object types and the tables in the target schema. Instead, you can use the Import DataPump parameter TRANSFORM which enables you to alter object creation DDL for the types. The value N (= No) for the transform name OID implies that a new OID is assigned. Example:

impdp system/manager DIRECTORY=my\_dir DUMPFILE=expdp\_u1.dmp LOGFILE=impdp\_u1.log

REMAP\_SCHEMA=u1:u2 TRANSFORM=oid:n...

Processing object type SCHEMA\_EXPORT/TYPE/TYPE\_SPEC

Processing object type SCHEMA\_EXPORT/TABLE/TABLE

Processing object type SCHEMA\_EXPORT/TABLE/TABLE\_DATA

. . imported "U2"."MY\_OBJTAB"                         6.125 KB       1 rows

. . imported "U2"."MY\_RELTAB"                         6.218 KB       1 rows

Job "SYSTEM"."SYS\_IMPORT\_FULL\_01" completed with 1 error(s) at 12:38:56

Note that the remaining error is an ORA-31684 "Object type USER:"U2" already exists", which was reported earlier at the import. This error is not related. The ORA-31684 can be ignored if the target schema already exists in the target database.

Also note that the transform name OID for the Import DataPump parameter TRANSFORM has been introduced in Oracle10g Release 2 (10.2.0.x.y). If you use this value in Oracle10g Release 1, the Import DataPump job will fail with:
