1.之前做了Oracle 10g Stream表级复制的配置()，在已经存在复制环境的情况下，再配置其他类型的复制前需要清除已经存在的复制环境，否则复制会导致失败。
使用stream管理员用户，源库操作如下：
SQL> conn streamadmin/oracle@primary
Connected.
SQL> begin
2 for cur_pro in (select propagation_name from dba_propagation) loop
3 dbms_propagation_adm.drop_propagation(cur_pro.propagation_name);
4 end loop;
5 dbms_streams_adm.REMOVE_STREAMS_CONFIGURATION;
6 end;
7 /
PL/SQL procedure successfully completed.
查看日志文件信息，部分如下：

查看stream相关的表的队列信息，如下：
SQL> select apply_name,queue_name,queue_owner,status from dba_apply;
no rows selected
SQL> select CAPTURE_NAME,QUEUE_OWNER,STATUS,CAPTURE_USER from dba_capture;
no rows selected
使用stream管理员，目标库操作如下：
SQL> conn streamadmin/oracle@standby;
Connected.
SQL> begin
2 for cur_pro in (select propagation_name from dba_propagation) loop
3 dbms_propagation_adm.drop_propagation(cur_pro.propagation_name);
4 end loop;
5 dbms_streams_adm.REMOVE_STREAMS_CONFIGURATION;
6 end;
7 /
PL/SQL procedure successfully completed.
查看日志文件信息，部分如下：

2.源库和目标库初始化参数设置
在源库：
alter system set aq_tm_processes=1 scope=spfile;
alter system set job_queue_processes=2 scope=spfile;
alter system set global_names=true scope=spfile;
alter database rename global_name to myorcl.net;
alter system set streams_pool_size=52m scope=spfile;
在目标数据库：
alter system set aq_tm_processes=1 scope=spfile;
alter system set job_queue_processes=2 scope=spfile;
alter system set global_names=true scope=spfile;
alter database rename global_name to orcl.net;
alter system set streams_pool_size=50m scope=spfile;
由于之前做了表级复制，现在只需验证配置信息是否正确。
3.在源库和目标库配置tnsnames.ora，如下：
primary =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.41.6.118)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = myorcl)
)
)
standby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.41.6.119)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
4.源库和目标库复制管理员的创建
不能使用sys和system作为流管理员，流管理员不能使用system表空间作为默认表空间；
在源库验证操作如下：
SQL> select username from dba_users where username like '%STREAM%'; --之前做表级复制时创建的stream管理员
USERNAME
------------------------------
STREAMADMIN
SQL> select TABLESPACE_NAME,STATUS from dba_tablespaces where TABLESPACE_NAME like '%STREAM%';
TABLESPACE_NAME STATUS
------------------------------ ---------
STREAMTBS ONLINE
在目标库验证操作如下：
SQL> select username from dba_users where username like '%STREAM%';
USERNAME
------------------------------
STREAMADMIN
SQL> select TABLESPACE_NAME,STATUS from dba_tablespaces where TABLESPACE_NAME like '%STREAM%';
TABLESPACE_NAME STATUS
------------------------------ ---------
STREAMTBS ONLINE
5.源库和目标库创建互连的数据库连接
在源库验证操作如下：
SQL> conn streamadmin/oracle@primary
Connected.
SQL> col owner for a15;
SQL> col db_link for a15;
SQL> col username for a15;
SQL> col host for a15;
SQL> select owner,db_link,username,host from dba_db_links;
OWNER DB_LINK USERNAME HOST
--------------- --------------- --------------- ---------------
STREAMADMIN ORCL.NET STREAMADMIN standby
SQL> select * from dual@orcl.net;
D
-
X
在目标库验证操作如下：
SQL> conn streamadmin/oracle@standby;
Connected.
SQL> col owner for a15;
SQL> col db_link for a15;
SQL> col username for a15;
SQL> col host for a15;
SQL> select owner,db_link,username,host from dba_db_links;
OWNER DB_LINK USERNAME HOST
--------------- --------------- --------------- ---------------
STREAMADMIN MYORCL.NET STREAMADMIN primary
SQL> select * from dual@myorcl.net;
D
-
X
6.查看源库和目标库是否处于归档模式
SQL> conn / as sysdba
Connected.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/app/my_arch
Oldest online log sequence 6
Next log sequence to archive 8
Current log sequence 8
