使用broker查看dataguard信息时有告警
DGMGRL> show configuration; Configuration - DRTEST Protection Mode: MaxPerformance Databases: ora11gn1 - Primary database ora11gn2 - Physical standby database Warning: ORA-16792: configurable property value is inconsistent with database setting Fast-Start Failover: DISABLED Configuration Status: WARNING
查看是哪个库出现的告警
DGMGRL> show database ora11gn1;
Database - ora11gn1
Role: PRIMARY
Intended State: TRANSPORT-ON
Instance(s):

Database Status:

DGMGRL> show database ora11gn2;

Apply Lag: 0 seconds
Real Time Query: ON
Instance(s):
ora11gn
Warning: ORA-16714: the value of property LogArchiveFormat is inconsistent with the database setting
Database Status:

原来是standby端的redo日志格式属性与数据库设置不一致，查看该属性的值
DGMGRL> show database verbose ora11gn2;

Database Status:

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;

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)
