dataguard上开启了standby redo log,实时同步,版本是11.2.0.3。
现在想把Rman做到备库上,问题是备库中的压缩等级没办法修改,提示如下。RMAN> configure compression algorithm 'HIGH';using target database control file instead of recovery catalogRMAN-00571: ===========================================================RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============RMAN-00571: ===========================================================RMAN-03002: failure of configure command at 08/11/2015 09:01:24RMAN-05021: this configuration cannot be changed for a BACKUP or STANDBY control file复制代码所以想请大家帮忙看一下该如何来解决这个问题,是否可以直接在backup database脚本中直接指定压缩等级,或者有不停机或重做的情况来解决问题的方法,tks
(11.2.0.4版本的DG中是可以修改,但是业务库暂时没办法停机升级)

试了,直接把configure和backup放一起用run也不行,
因为现有的DG环境就有参数不同,我以为这个参数也可以这样子用,经查后应该是无法用run来解决
这里有讨论,看来是要重建standby controlfile
https://community.oracle.com/thread/2454016
1. shutting down standby
2. configuring retention policy on primary
3. taking a backup controlfile from primary
4. copying it across to the standby
5. restarting standby using the backed-up controlfile
