Solution for migrating oracle database from a later version to a lower version

Yesterday, I want to migrate the database on my machine to a dedicated server. The local Oracle10g is installed, and the database installed on the server is Oracle9i. I will first perform the following operations: export the database file locally: exp gzwp/wlkp @ taxser file = d: \ 20130226.dmp owner = gzwp get the Server Import: imp gzwp/wlkp @ taxser file = d: \ 20130226.dmp fromuser = gzwp touser = gzwp ignore = y error:
IMP-00010: the exported file is not valid and title verification fails.
IMP-00000: Import failedThe reason is that the database version is incorrect. Oracle does not support importing a later version to a later version.. Solution:
1. configure an Oracle database on the server to connect to the local Oracle10g (called taxser134) by using the help tool Net Manager provided by oracle or modifying tnsname. tra9i Directory: % oracle_home % \ ora92 \ network \ admin, 10 Gb Directory: % oracle_home % \ product \ 10.2.0 \ db_1 \ NETWORK \ ADMIN)
Export the database file exp gzwp/wlkp @ taxser134 file = d: \ 20130226.dmp owner = gzwp 2. create a database, user, and tablespace on the remote server: 1>. you can use the oracle tool Database Configuration Assistant to create a Database instance (ntaxser ):
Note that the selected character set corresponds to the local database; otherwise, Chinese characters may be garbled. 2>. sqlplus sys/wlkp as sysdbacreate user gzwp identified by wlkp; grant connect, resource, dba, create session to gzwp; create tablespace WLKPTABLE

Datafile 'f: \ oracle \ product \ 10.1.0 \ oradata \ ntaxser \ WLKPTABLE. dbf'

Autoextend on
Next 50 m maxsize 20480 m
Extent management local ;//....... all tablespaces used 3. import the file to the server: imp gzwp/wlkp @ ntaxser file = d: \ 20130226.dmp fromuser = gzwp touser = gzwp ignore = y. Import successful! In fact, all solutions for migrating oracle databases from a later version to a later version are similar: configure a connection to a later version of the database on an earlier version of Oracle, use the earlier version of the oracle client to export data files and then import them.
