  • ORACLE DG同步异常

    若归档日志在同步,数据文件没有同步,可尝试如下方式解决:

    1.select process,status,sequence# from v$managed_standby; (检查MRP进程在不,如不在,则没有应用归档,继续执行如下命令)
    
    2.shutdown immediate;
    
    3.startup mount;
    
    4.alter database recover managed standby database disconnect from session;
    
    5.alter database recover managed standby database cancel;
    
    6.alter database open;
    
    7.alter database recover managed standby database using current logfile disconnect from session;
    
    8.select process,status,sequence# from v$managed_standby;

    查看归档日志是否被应用:

    select name,SEQUENCE#,APPLIED from v$archived_log order by sequence#;
