How to import Oracle 10 GB Data to Oracle 9i?

Generally, it is not a problem to import data from a lower version to a later version. The trouble is to import data from a later version to a lower version. Before Oracle9i, EXP/IMP between Oracle versions can be solved through the following methods:

1. Run catexp. SQL of the base version on the High Version database;

2. Use exp of a lower version to export data of a later version;

3. Use the lower-version IMP to import the database to the database of the actual version;

4. Run the catexp. SQL script in the later version of the database.

But in 9i, the above method cannot solve the problem. If you use the base version exp/IMP directly, the following error occurs:

EXP-00008: Oracle error % lu encountered

ORA-00904: Invalid column name

This is a published bug that can be solved only after oracle10.0. The bug number is 2261722. You can go to Metalink to view details about this bug.

Bug is a bug. We still need to do our work. We should solve the bug by ourselves before we have Oracle Support. Execute the following SQL statement in Oracle9i to recreate the exu81rls view.

Create or replace view exu81rls

As select U. Name, O. Name, R. pname, R. pfschma, R. ppname, R. pfname,

Decode (bitand (R. stmt_type, 1), 0, '', 'select ,')

| Decode (bitand (R. stmt_type, 2), 0, '', 'insert ,')

| Decode (bitand (R. stmt_type, 4), 0, '', 'Update ,')

| Decode (bitand (R. stmt_type, 8), 0, '', 'delete ,'),

R. check_opt, R. enable_flag,

Decode (bitand (R. stmt_type, 16), 0, 0, 1)

From user $ U, OBJ $ o, RLS $ R

Where U. User # = O. Owner #

And R. OBJ # = O. OBJ #

And (uid = 0 or

Uid = O. Owner # Or

Exists (select * From session_roles where role = 'select _ catalog_role ')
