    7.配置 dgmgrl

    [oracle@localhost dbs]$ dgmgrl /

    Fast-Start Failover: DISABLED
    
    Configuration Status:
    WARNING
    
    DGMGRL> exit
    

    这里又报了一个错:原来刚才只给主库配置了 redo logs 备库上遗漏了

    #备库上配置 redo logs
    [oracle@localhost dbs]$ 
    [oracle@localhost dbs]$ sqlplus / as sysdba

    再次查看dgmgrl 配置

    [oracle@localhost dbs]$ dgmgrl /
    DGMGRL for Linux: Version 11.2.0.4.0 - 64bit Production
    
    Copyright (c) 2000, 2009, Oracle. All rights reserved.

    Fast-Start Failover: DISABLED
    
    Configuration Status:
    SUCCESS
    DGMGRL> exit
    

    现在么问题,success
