Thứ Hai, 19 tháng 1, 2026

Export Table từ Oracle 11g lên Oracle 12c PDB

Mục đích: Export Table từ Oracle 11g lên Oracle 12c PDB

Source DB Server:

OS: OEL 7.5

Database Name: CLONE

DB Version: 11.2.0.4

Schema: RUPESH

TABLE: EMP

Tablespace: TEST

Target DB Server:

OS: OEL 7.5

Database Name: ORCL

Pluggable DB Name: ORCLPDB

DB Version: 12.2.0.1

Schema: C##RUPESH => Local User

Tablespace: USERS

Step 1: Check current versions of both source and target DBs.

Source:

[oracle@clone oracle]$ sqlplus / as sysdba

You can check whether pluggable feature is enabled or not using below command.

SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED

------ ------------- ---------- ----------

2 PDB$SEED READ ONLY NO

3 ORCLPDB READ WRITE NO

Step 2: Get table metadata details from source DB.

SQL> set lines 300 pages 3000

SQL> col directory_name for a13

SQL> col directory_path for a34

SQL> col owner for a13

SQL> select * from dba_directories where directory_name='DIR';
