文档解释

ORA-16525: the Data Guard broker is not yet available

Cause: The Data Guard broker process was either not yet started, was initializing, or failed to start.

Action: If the broker has not been started, set the DG_BROKER_START initialization parameter to true and allow the broker to finish initializing before making the request. If the broker failed to start, check the Data Guard log for possible errors. Otherwise, retry the operation.

ORA-16525错误是指Data Guard代理服务的连接不可用。

官方解释

ORA-16525被称为“Data Guard broker not available”。 全局数据库名称连接到FAL负责人,以设置Data GUarding特性时发生这个ORA错误。

常见案例

1. 当尝试设置DG实例关联性或者DG Broker功能时,使用DGMGRL可能会发生ORA-16525错误。

2. 当停止并再启动Data Guard Broker进程时,可能会遇到ORA-16525错误。

一般处理方法及步骤

1. 使用ALTER SYSTEM命令检查Data Guard Broker进程是否正常启动,并确保是正常启动的状态

SQL> alter system set dg_broker_start=true;

System altered.

2. 尝试重新连接到实例,确认DGM GRL连接是否可用。

3. 如果上述措施都没有成功解决问题,则可以使用“lsnrctl status”来检查服务监听器是否正常工作。 如果发现不正常,则需要重新启动服务监听器来解决问题。

4. 将Data Guard Broker关闭,然后再重新启动它,以确保它正确运行

SQL> alter system set dg_broker_start=false;

System altered.

SQL> alter system set dg_broker_start=true;

System altered.
