Database Status:

WARNING

broker设置的属性值LogArchiveFormat = 'log_%d_%T_%s_%p.arc'

进一步查看broker的监控属性InconsistentProperties

DGMGRL> show database ora11gn2 InconsistentProperties;

INCONSISTENT PROPERTIES

   INSTANCE_NAME        PROPERTY_NAME         MEMORY_VALUE         SPFILE_VALUE         BROKER_VALUE

         ora11gn     LogArchiveFormat         %t_%s_%r.dbf  log_%d_%T_%s_%p.arc  log_%d_%T_%s_%p.arc

这里明确显示了spfile与broker是一致的，由于该参数无法在线修改，所以spfile中的值只能等下一次重启后才能生效；为了消除报错，可将spfile和broker的值都改回修改前的，与MEMORY_VALUE一致，或者只临时修改broker中的属性值，但下一次重启前记得要修改成与spfile一致，否则重启后这里还会有告警

DGMGRL> EDIT DATABASE ora11gn2 SET PROPERTY LogArchiveFormat='%t_%s_%r.dbf';

Property "logarchiveformat" updated

DGMGRL> show configuration;

Configuration - DRTEST

  Protection Mode: MaxPerformance

  Databases:

    ora11gn1 - Primary database

    ora11gn2 - Physical standby database

Fast-Start Failover: DISABLED

Configuration Status:

DGMGRL> show database ora11gn2 InconsistentProperties;

INCONSISTENT PROPERTIES

   INSTANCE_NAME        PROPERTY_NAME         MEMORY_VALUE         SPFILE_VALUE         BROKER_VALUE

上面使用show database verbose命令输出的属性值为'(monitor)'的是用于监控的只读属性，主要有

■ InconsistentLogXptProps　　不一致的redo日志传输属性(primary)

■ LogXptStatus　　redo日志传输状态(primary)

■ InconsistentProperties　　不一致的数据库属性

■ SendQEntries　　日志发送信息(primary)

■ RecvQEntries　　日志接收信息(standby)

■ StatusReport　　报错或告警

■ LatestLog　　最近的drc告警日志(drc<db_unique_name>.log)信息

■ TopWaitEvents　　top5等待事件(v$system_event)
