1 SharePlex 软件路径和数据路径
软件路径productdir：程序文件和库文件
数据路径vardir：工作路径，包括：队列文件、日志文件、与当前复制环境相关的组件。
注意：不要删除、重命名或者编辑SharePlex默认安装的文件和目录，有隐藏文件是数据
复制必须的文件。即使空文件也必须保留，这些文件是SharePlex进程需要的。
sp_cop进程：该进程协调Share_Plex的复制进程，如Capture,Read,Export,Import,Post进程，SharePlex队列，
该进程初始化所有的后台进程，维护复制网络中与其他系统的通信功能。
该进程很少与用户交互，除了启动和关闭外，该进程一旦运行就成为后台进程。
sp_ctrl进程：启动，关闭以及监控SharePlex
SharePlex复制相关进程，源库read,capture,export, 目标库：import post
后续三个重要步骤
1 安装SharePlex软件
这个需要设置两个目录productdir，vardir，需要用户名和序列号
2配置数据库，执行ora_setup脚本，根据提示输入即可，这个在源和目标都要执行。
3 迁移数据
导出数据

4 激活配置文件
activate config myconfig
myconfig内容如下：
Datasource:o.prod
SCOTT.sales SCOTT.sales sp22@o.prods
SCOTT.CUSTOMERS SCOTT.CUSTOMERS sp22@o.prods
sp_ctrl (sp11:3500)> show config
Tables Replicating with Key:
"SCOTT"."CUSTOMERS" KEY: CUST_ID
"SCOTT"."SALES" KEY: SALES_ID
File Name :myconfig
Datasource :prod
Activated :29-Sep-20 10:27:05
Actid :5
Total Objects :2
Total Objects Replicating :2
Total Objects Not Replicating :0
View config summary in /splex/vardir921/log/prod_config_log
激活配置文件后，会自动启动源和目标库的响应后台进程，并开始次同步数据。
