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

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;

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
