描述：
源数据库为两台集群64位HP-UNIX的Oracle11gR2数据库，
目标数据库为1台64位Linux的Oracle11gR2的数据库，
把源数据库的某个用户的数据传输到目标数据库中
1、源数据库、目标数据库均为归档模式
源：

Database log mode Archive Mode
Automatic archival Enabled
Archive destination +ARCHDG
Oldest online log sequence 60
Next log sequence to archive 61
Current log sequence 61
目标：
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 54
Current log sequence 56
SQL> startup mount
ORACLE instance started.
Total System Global Area 6747725824 bytes
Fixed Size 2213976 bytes
Variable Size 4697622440 bytes
Database Buffers 2013265920 bytes
Redo Buffers 34623488 bytes
Database mounted.
SQL> alter database archivelog;
Database altered.
SQL> alter database open;
Database altered.
2、设置源、目标数据库的相关参数
源：
SQL> show parameter global_names
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
global_names boolean FALSE
SQL>
SQL> alter system set global_names=true scope=both;
System altered.
SQL> show parameter aq_tm_processes
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
aq_tm_processes integer 0
SQL> alter system set aq_tm_processes=2 scope=both;
System altered.
目标：
SQL> show parameter global_names
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
global_names boolean FALSE
SQL>
SQL> alter system set global_names=true scope=both;
System altered.
SQL> show parameter aq_tm_processes
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
aq_tm_processes integer 0
SQL> alter system set aq_tm_processes=2 scope=both;
System altered.
3、在源数据库启用追加日志
启用辅助日志
SQL> alter database add supplemental log data;
Database altered.
4、在源、目标数据库创建表空间、用户、授权
源：
查看数据文件位置：
select file_name from dba_data_files
创建表空间：
create tablespace streams_space
datafile '+DATADG/cboms/datafile/streams_space.dbf'
size 5M autoextend on
创建用户：
create user strmadmin
identified by strmadmin
default tablespace streams_space
授予dba角色：
grant dba to strmadmin
授予流管理权限：
exec dbms_streams_auth.grant_admin_privilege('strmadmin') ----使用sys 或 system在命令行执行
目标：
查看数据文件位置：
select file_name from dba_data_files
创建表空间：
create tablespace streams_space
datafile '/u01/app/oracle/oradata/bhoms/streams_space.dbf'
size 5M autoextend on
创建用户：
create user strmadmin
identified by strmadmin
default tablespace streams_space
授予dba角色：
grant dba to strmadmin
授予流管理权限：
exec dbms_streams_auth.grant_admin_privilege('strmadmin') ----使用sys 或 system在命令行执行
5、配置源、目标数据库的tnsnames.ora
源数据库节点1：
CBDBS01-> cd $ORACLE_HOME
CBDBS01-> pwd
/oracle/db/product/11.2.0/db_1
CBDBS01-> cd network/admin
CBDBS01-> vi tnsnames.ora
在文件中末尾增加：
BHOMS_192.168.2.2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms)
)
)
测试连接到目标数据库
CBDBS01-> sqlplus testUser/testPassword@BHOMS_192.168.2.2
源数据库节点2：
源数据库节点1：
CBDBS02-> cd $ORACLE_HOME
CBDBS02-> pwd
/oracle/db/product/11.2.0/db_1
CBDBS02-> cd network/admin
CBDBS02-> vi tnsnames.ora
在文件中末尾增加：
BHOMS_192.168.2.2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms)
)
)
测试连接到目标数据库
CBDBS02-> sqlplustestUser/testPassword@BHOMS_192.168.2.2
目标数据库：
[www.linuxidc.com@linuxidc ~]$ cd $ORACLE_HOME
[www.linuxidc.com@linuxidc dbhome_1]$ cd network
[www.linuxidc.com@linuxidc network]$ cd admin
[www.linuxidc.com@linuxidc admin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
在这目录下没有tnsnames.ora文件，新建一个tnsnames.ora文件，然后增加下面的内容：
[www.linuxidc.com@linuxidc admin]$ vi tnsnames.ora
CBOMS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1568))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1568))
(LOAD_BALANCE = yes)
(FAILOVER = ON)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cboms)
(FAILOVER_MODE =
(TYPE = Select)
(METHOD = BASIC)
)
)
)
测试是否连接到源数据库。
[www.linuxidc.com@linuxidc admin]$ sqlplus testUser/testPassword@CBOMS
6、在源、目标数据库创建到目标数据库的db_link
源：
SQL> conn strmadmin/strmadmin
SQL>create database link BHOMS connect to strmadmin identified by strmadmin using 'BHOMS_192.168.2.2';
测试：
select * fromglobal_name@BHOMS
目标：
SQL> conn strmadmin/strmadmin
SQL>create database link CBOMS connect to strmadmin identified by strmadmin using 'CBOMS';
测试：
select * fromglobal_name@CBOMS
