6. Setup Schema for streams
Schema: SCOTT
Table: Taj
NOTE: Unlock scott schema because in 10g scott schema is locked by default
Source Database: DB1
SQL> conn sys@db1 as sysdba
Enter password:
Connected.
SQL> alter user scott account unlock identified by tiger;

User altered.

SQL> conn scott/tiger@db1
Connected.
SQL> create table TAJ ( no number primary key,name varchar2(20),ddate date);

Table created.

Target Database: DB2
SQL> conn sys@db2 as sysdba
Enter password:
Connected.
SQL> alter user scott account unlock identified by tiger;

User altered.

SQL> conn scott/tiger@db2
Connected.
SQL> create table TAJ ( no number primary key,name varchar2(20),ddate date);

Table created.

7. Setup Supplemental logging at the source database
Source Database: DB1
SQL> conn scott/tiger@db1
Connected.
SQL> alter table taj
2 add supplemental log data (primary key,unique) columns;

Table altered.

8. Configure capture process at the source database

9 inclusion_rule => true);
10 end;
11 /

2 source_scn number;
3 begin
4 source_scn := dbms_flashback.get_system_change_number();
5 dbms_apply_adm.set_table_instantiation_scn@DB2
