--控制Manager 等待分配端口的时间。
(4) AUTOSTART: Starts Extract andReplicat processes when Manager starts. This can be useful, for example, if youwant Oracle GoldenGate activities to begin immediately when you start thesystem, assuming Manager is part of the startup routine. You can use multiple AUTOSTARTstatements in the same parameter file.
--在Manager 启动时，自动启动Extract和replicat进程。 这是一个有用的命令，可以将Manager 添加到stratup routine里，这样Manager启动之后，Extrace 和Replicat 也就可以自动启动了。
(5) AUTORESTART: Starts Extract andReplicat processes again after abnormal termination.
--当Extract 和Replicat 进程异常中断后自动启动。
(6) PURGEOLDEXTRACTS: Purges trailfiles when Oracle GoldenGate has finished processing them. Without using PURGEOLDEXTRACTS,no purging is performed, and trail files can consume significant diskspace.Using PURGEOLDEXTRACTS as a Manager parameter is preferred over using theExtract or Replicat version of PURGEOLDEXTRACTS.
--当trail file 处理完后purge它们，如果没有指定该参数，trail file 会占用大量的磁盘空间。 Manager 的PURGEOLDEXTRACTS参数优先级比Extrace 和Replicat 的PURGEOLDEXTRACTS高。 即会先使用Manager的该参数。
NOTE：
When using PURGEOLDEXTRACTS,do not permit trail files to be deleted by any user or program other than OracleGoldenGate. It will cause PURGEOLDEXTRACTS to function improperly.
注意，如果使用PURGEOLDEXTRACTS，那么不允许出GG之外的用户和程序删除trail files 文件。 否则会导致PURGEOLDEXTRACTS异常。
四.Starting Manager
Manager must berunning before you start other Oracle GoldenGate processes. You can startManager from:
--Manager 必须先与GG 进程启动
(1) The command line of any supportedoperating system
(2) GGSCI
(3) The Services applet on aWindows system if Manager is installed as a service. See the Windowsdocumentation or your system administrator.
(4) The Cluster Administrator toolif the system is part of a Windows cluster. This is the recommended way tobring the Manager resource online. See the cluster documentation or your systemadministrator.
(5) The cluster software of a UNIXor Linux cluster. Refer to the documentation provided by the cluster vendor todetermine whether to start Manager from the cluster or by using GGSCI or thecommand line of the operating system.
4.1 To start Manager from the command line
To run Managerfrom the command shell of the operating system, use the following syntax.
mgr paramfile [reportfile
The reportfile argumentis optional and can be used to store the Manager process report in a locationother than the default of the dirrpt directory in the Oracle GoldenGateinstallation location.
4.2 To start Manager from GGSCI
1. From the Oracle GoldenGate directory,run GGSCI.
2. In GGSCI, issue the following command.
START MANAGER
On Windows systems, you can use the BOOTDELAYMINUTES parameter to specify how long aftersystem boot time Manager delays until it starts its processing activities.
NOTE:
When startingManager from the command line or GGSCI on Windows Server 2008 with User Account Control enabled, you will receive a UAC prompt requesting you to allow or deny the program to run.
五.Stopping Manager
Manager runsindefinitely or until stopped by a user. In general, Manager should remain runningwhen there are synchronization activities being performed. Manager performs importantmonitoring and maintenance functions, and processes cannot be started unless Manageris running.
--在停Manager 之前，需要先停GG 进程，因为Manager负责监控和维护其他的进程。
To stop Manager
