Each Oracle GoldenGate installation is rooted in the Manager process. This is the
controller process that instantiates the Oracle GoldenGate processes, allocates port
numbers, and performs file maintenance. Together, the Manager process and its child
processes, and their related programs and files comprise an Oracle GoldenGate
instance.
每个OGG安装是严源于管理进程。这是一个实例化OGG进程的控制进程，分配端口号，
日常维护。管理进程和它的子进程，还有相关的程序和文件构成了OGG的实例。
To run Oracle GoldenGate, a Manager process must be running on all systems that
will be part of the Oracle GoldenGate environment. To run Manager, you first create a
parameter file for it.
To create the Manager parameter file
1. From the Oracle GoldenGate directory, run the ggsci program to open the Oracle
GoldenGate Software Command Interface (GGSCI).
2. In GGSCI, edit the Manager parameter file.
EDIT PARAMS MGR
3. Add the Manager parameters, each on one line. If a parameter statement must
span multiple lines, use an ampersand (&) before each line break.
运行OGG，管理进程必须运行在OGG环境的组成部份系统上。运行管理器前先创建一个
参数文件。
创建参数文件包含：
1.从OGG的目录中，运行GGSCI程序去打开OGG的命令接口.
2.在GGSCI,编辑管理参数文件。EDIT PARAMS MGR
3.添加管理参数在每行上。如果一个参数语句必须扩展成多行，使用一个&在每行中断前。
■ The only required Manager parameter is PORT, but DYNAMICPORTLIST is stronly
recommended.
■ In a cluster environment, configure Manager with the AUTOSTART and
AUTORESTART parameters, so that the Oracle GoldenGate processes start or
restart automatically when Manager is started or fails over.
■ Use PURGEOLDEXTRACTS to manage the accumulation of trail files.
■ For more information about Manager parameters, see the Oracle GoldenGate
Windows and UNIX Reference Guide.
For more details on configuring Manager and its network connections, see the
Oracle GoldenGate Windows and UNIX Administrator's Guide.
4. Save, then close the file.
#唯一的要求管理参数是端口，但是DYNAMICPORTLIST是强烈建议加上去的。
#在集群环境，环境管理器使用AUTOSTART和AUTORESTART参数，这样OGG进程
启动或者自动重启当管理器启动或者失败过。
#使用PURGEOLDEXTRACTS去管理累积的跟踪文件。
#获得更多的信息关于配置管理器和它的网络连接，查看OGG WINDOW和UNIX管理员手册。
4.保存，然后关闭文件。
