1)创建SPLEX用户及设置归档模式
A 、源端与目标端--创建用户及授权(注意系统时间):
create user splex identified by splex default tablespace users;----最好为SPLEX用户单独创建一个表空间
grant dba,connect,resource to splex;---SPLEX必须有DBA权限
源端必须处于归档模式
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 7
Next log sequence to archive 9
Current log sequence 9
alter database add supplemental log data (primary key,unique index) columns;
目标端创建需同步进去的数据(注意在目标端创建好源端默认表空间及数据表空间)
create user test identified by test default tablespace TBS_DATA01;
grant connect,resource,unlimited tablespace to test;
2) 安装shareplex

$ ./ora_setup
Welcome to the Oracle SharePlex setup process.
This process creates tables and user accounts needed to run
Oracle SharePlex replication.
Please note the following:
** In response to prompts, a carriage return will choose the default
given in brackets. If there is no default, a reply must be entered.
** To exit the program while the program is waiting for input, use the
CTRL-C key sequence.
This sequences can be entered by holding down the CONTROL key and
pressing the C key.
Enter the Oracle SID for which SharePlex should be installed [hrdb] :
In order to create the SharePlex tables and user account, we must
connect to the database as a DBA user
Enter a DBA user name : system
Enter password for the DBA account, which will not echo :
注意:RAC环境下,此处输入oracle数据库system帐户的口令,但应当在口令的后面加上@TNS_ALIAS,然后回车;

3)目标端安装shareplex
安装shareplex过程中./SharePlex-7.6.1-b27-oracle100-rh-40-amd64-m64.tpm及./ora_setup类似,不同
之外在于
Oracle ASM detected. Enable SharePlex ASM support? [y] :
SharePlex ASM support enabled.
(备注:如在源端或目标端都有安装过shareplex,则记得清除SPLEX用户capture或post信息,则在启动前记得以下操作:
./ora_cleansp splexhr/splexhr
)
3) 源端操作
A 、启动shareplex
[oracle@hrdb bin]$ ./sp_cop -u2200 &
[1] 25839
[oracle@hrdb bin]$

C 、添加配置文件
sp_ctrl (hrdb:2200)> list config

4)目标端操作
$./sp_cop -u2200 &
$./sp_ctrl
sp_ctrl (backupdb:2200)> status

There are no active configuration files
sp_ctrl (backupdb:2200)> stop post
5)源端
sp_ctrl (hrdb:2200)> activate config hr_config
Not all tables activated successfully
源端-导出数据(这里使用SCN来保证 一致性):
SQL> set num 50expdp system/XXXX DIRECTORY=DUMP_DIR DUMPFILE=20120730_HR.dmp FLASHBACK_SCN=165290627611 SCHEMAS=test LOGFILE=20120730_HR.log
或用EXP方式
6) 目标端
impdp system/oracle DIRECTORY=DUMP_DIR DUMPFILE=20120730_HR.dmp SCHEMAS=test LOGFILE=impdp_2012730_HR.log
或用IMP方式
禁用查找相关JOB
select job_name from dba_scheduler_jobs where OWNER='TEST';
禁用触发器
select 'alter trigger '||owner||'.'||object_name||' disable'
from dba_objects
where object_type='TRIGGER' and owner='TEST';
查找外键及约束
select 'alter table '||t.owner||'.'||t.table_name||' disable constraint '||t.constraint_name||';'
From dba_constraints t
where owner='TEST' and constraint_type='R';
sp_ctrl (backupdb:2200)> qstatus

清除源端或目标端下队列记录信息:
$ ./ora_cleansp splexhr/splexhr
在CONFIG文件配置错误的情况下已经activate时,需deactivate config后再行编辑激活;否则,有可能激活CONFIG后,一直HANG住
***********************************
注意在RAC环境下:
1、如果两个节点的实例名字不一样,就必须在Oracle10g RAC的两个节点的tnsnames.ora文件中都建立一个TNS别名,然后在/etc/oratab文件中添加如下入口:
splex:/oracle/product/db/10.2:N
其中splex为新建的TNS别名;ORACLE_HOME为Oracle的HOME目录的全路径2、如果RAC中各个节点的ORACLE_HOME不同,应该在两个节点上oracle用户下创建相同符号连接指向示本地的ORACLE_HOME 。然后编辑oratab文件,将文件中的路径改成符号连接。
# ln -s /local_ORACLE_HOME /$ORACLE_HOME
编辑 oratab file : SID:/pathname_to_symbolic_link:N
