2.在源库与目标库初始化参数设置
在源库操作如下：
SQL> select instance_name,status from v$instance;
INSTANCE_NAME STATUS
---------------- ------------
myorcl OPEN
SQL> alter system set aq_tm_processes=1 scope=spfile; --队列等待时间
SQL> alter system set job_queue_processes=2 scope=spfile; --至少为2
SQL> alter system set global_names=true scope=spfile; --用来控制database link同名
SQL> alter database rename global_name to myorcl.net;
SQL> alter system set streams_pool_size=50m scope=spfile;
重启数据库并查看设置的global_name，如下：
SQL> shutdown immediate
SQL> startup
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
MYORCL.NET
在目标库操作，如下：
SQL> select instance_name,status from v$instance;
INSTANCE_NAME STATUS
---------------- ------------
orcl OPEN
SQL> alter system set aq_tm_processes=1 scope=spfile;
SQL> alter system set job_queue_processes=2 scope=spfile;
SQL> alter system set global_names=true scope=spfile;
SQL> alter database rename global_name to orcl.net;
SQL> alter system set streams_pool_size=50m scope=spfile;
SQL> shutdown immediate
重启数据库并查看设置的global_name，如下：
SQL> shutdown immediate
SQL> startup
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
ORCL.NET
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)
)
)
测试能否连通，如下：
首先关闭防火墙，service iptables stop
在源库测试，如下：
[oracle@dayong ~]$ tnsping standby
TNS Ping Utility for Linux: Version 10.2.0.1.0 - Production on 03-APR-2014 11:47:41
Copyright (c) 1997, 2005, Oracle. All rights reserved.
Used parameter files:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.41.6.119)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = orcl)))
OK (10 msec)
在目标库测试，如下：
[oracle@xiaoru ~]$ tnsping primary
TNS Ping Utility for Linux: Version 10.2.0.1.0 - Production on 03-APR-2014 11:53:24

OK (0 msec)
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；
源库操作如下：
SQL> create tablespace streamtbs datafile '/u01/app/oradata/myorcl/streamtbs.dbf' size 100m;
SQL> create user streamadmin identified by oracle default tablespace streamtbs quota unlimited on streamtbs;
SQL> grant connect,resource,dba to streamadmin;
目标库操作如下：
SQL> create tablespace streamtbs datafile '/u01/app/oradata/orcl/streamtbs.dbf' size 100m;
SQL> create user streamadmin identified by oracle default tablespace streamtbs quota unlimited on streamtbs;
SQL> grant connect,resource,dba to streamadmin;
