ORA-16626: failed to enable specified database ORACLE 报错 故障修复 远程处理

文档解释

ORA-16626: failed to enable specified database

Cause: This status was returned when attempting to enable a standby database that:
– Could not locate itself in the broker configuration file.
– Failed to distinguish itself from two or more databases in the configuration file.
– Determined it missed a role change within the configuration.

Action: To correct the problem, try one of these actions:
– Confirm that the host and SID names for the database exactly match the values in the HOST_NAME and INSTANCE_NAME columns of V$INSTANCE.
– Confirm that there are not two or more databases with the same connect identifier. That is, multiple databases in the broker configuration should not reach the same database.
– If a failover had been performed and the old primary database has been re-created (or a standby database has been re-created), make sure the Data Guard broker configuration files have been removed for that database. Do NOT remove the configuration files that are in use by the new primary database.

常见案例

ORA-16626 错误一般出现在对数据库或服务器节点更改时。更改可能包括：创建新的数据库实例或在现有实例上安装新特性，如高可用性或数据库可扩展性。

一般处理方法及步骤

1. 首先，检查创建数据库或更改的具体错误，位于Oracle错误日志中。

2. 根据错误仔细检查硬件和软件环境，保证其符合Oracle安装和使用的要求。

3. 如果以上都验证通过，可能是Oracle数据库在初始化或更新时出现了问题，可以运行恢复脚本来尝试解决。

4. 当发现有数据库正在运行时，可以尝试升级它来解决问题。

5. 尝试使用“alter system set restart_services=true sid=’*’ scope=both;” 将所有服务重新启动，并在更改完成后重新启动服务，可能会解决这个故障。

6. 如果上述方法仍然不能解决问题，请尝试联系Oracle客户支持以获取进一步的帮助。
