这里简绍下管理进程中的两个重要参数：
DYNAMICPORTLIST： Specifies the ports that Collector can dynamically allocate.
If a firewall is being used at an Oracle GoldenGate target location, additional ports are
required on the target system to receive dynamic TCP/IP communications from remote
Oracle GoldenGate processes。
主要是当目标端有防火墙设置时或者主端的投递进程传送数据要经过防火墙才能到达备端时，这样需要在网络上开通指定的端口，那么这些端口的设置就用该参数。用于主端和备端的进程通信。
PORT： The Manager process in each Oracle GoldenGate installation requires a dedicated port for
communication between itself and other local Oracle GoldenGate processes. To specify this
port, use the PORT parameter in the Manager parameter file.
Establishes the TCP/IP port number on which Manager listens for requests.
管理进程的监听端口。用于本地goldengate 进程之间的通信。
