ORA-16830: primary isolated from fast-start failover partners longer than FastStartFailoverThreshold seconds: shutting down ORACLE 报错 故障修复 远程处理

文档解释

ORA-16830: primary isolated from fast-start failover partners longer than FastStartFailoverThreshold seconds: shutting down

Cause: The primary database was isolated from both the observer and target standby database for longer than the seconds specified by the FastStartFailoverThreshold property. A fast-start failover probably occurred. If the FastStartFailoverPmyShutdown configuration property was set to TRUE, the broker will shut down the primary database in this situation.

Action: Ensure one instance of this database is running and the database is mounted on that instance so that the broker may reinstate the old primary database.

ORA-16830是一个由FastStartFailover(FSFO)技术引起的Oracle数据库错误,它表示主数据库在某个时间段内从它的快速启动失败恢复(FSFO)伙伴隔离,因此无法正常的恢复它的主机位置。

官方解释

根据Oracle 11g文档,”当主实例检测到它的FSFO启动失败恢复(FSFO)伙伴仅仅在指定的时间内比FSFO的FastStartFailoverThreshold参数的指定时间更长时间隔离时,我们可以收到ORA-16830错误。”

常见案例

用户在使用Oracle FSFO时,因网络问题或其他技术问题,会出现ORA-16830错误。

一般处理方法及步骤

1.确认问题是否由FSFO技术引起,如果是,则可以采取以下步骤来解决:

2.检查网络是否存在问题,检查并尝试恢复连接

3.如果网络连接没有问题,那么检查FSFO状态是否正常,并重新启动FSFO

4.检查FastStartFailoverThreshold参数,确保它没有被设置得太低

5.如果以上步骤都不能解决该问题,则可以尝试重新启动ORACLE数据库
