LOG_ARCHIVE_CONFIG 的困惑

LOG_ARCHIVE_CONFIGProperty Description
Parameter type String
Syntax LOG_ARCHIVE_CONFIG =
{
[ SEND | NOSEND ]
[ RECEIVE | NORECEIVE ]
[ DG_CONFIG=(remote_db_unique_name1 [, ... remote_db_unique_name9) | NODG_CONFIG ]
}
Default value 'SEND, RECEIVE, NODG_CONFIG'
Modifiable ALTER SYSTEM
Basic No
LOG_ARCHIVE_CONFIG enables or disables the sending of redo logs to remote destinations and the receipt of remote redo logs, and specifies the unique database names (DB_UNIQUE_NAME) for each database in the Data Guard configuration.
Values:
•SEND
Enables the sending of redo logs to remote destinations
•NOSEND
Disables the sending of redo logs to remote destinations
•RECEIVE
Enables the receipt of remotely archived redo logs
•NORECEIVE
Disables the receipt of remotely archived redo logs
•DG_CONFIG
Specifies a list of up to 9 unique database names (defined with the DB_UNIQUE_NAME initialization parameter) for all of the databases in the Data Guard configuration.
•NODG_CONFIG
Eliminates the list of service provider names previously specified with the DG_CONFIG option.
但假设我现在
主库 DB_UNique_name = PRI
备库 DB_UNique_name = ST
那么如果我设置成
LOG_ARCHIVE_CONFIG='NORECEIVE,DG_CONFIG= (PRI,ST) '
那不意味着主库和备库都接收不了日志,那么dataguard岂不是成了一句空话
因为日志接收都不支持,那么何况是同步呢?
请问这个问题哪位大侠指点一下啊? 也许为了某种需要可以设置暂时停止接收日志吧! hzhg 发表于 2013-4-2 10:15 static/image/common/back.gif

这不还是没有个结论吗? 关键这个也比较令人费解
•NODG_CONFIG
Eliminates the list of service provider names previously specified with the DG_CONFIG option.
什么时候需要 消除之前的配置service provider啊? 本帖最后由 etl2007 于 2014-8-10 10:04 编辑
但是我现在还是有疑问,如果我设置成
LOG_ARCHIVE_CONFIG='NOSEND,DG_CONFIG= (PRI,ST) '
假设我现在PRI 这个数据库的角色就是Primary ROLE
那么岂不是主库也不能send日志啊?
有哪种场景需要这样配置呢? etl2007 发表于 2013-11-7 23:14 static/image/common/back.gif

•NODG_CONFIG
setup NODG_CONFIG when you want to delete DG??? 确实有点费解,不过应该是有他存在的道理的
