ORA-16076: unknown standby database destination ORACLE 报错 故障修复 远程处理

文档解释

ORA-16076: unknown standby database destination

Cause: A standby database destination was specified that was not accessed by another instance. If the initialization parameter LOG_ARCHIVE_CONFIG does not define a DG_CONFIG, this mismatch may be due to a standby database having been restarted recently.

Action: Ensure that at each instance the set of standby databases referred to by LOG_ARCHIVE_DEST_n initialization parameters is the same and define a DG_CONFIG at each instance to identify those databases explicitly.

ORA-16076: unknown standby database destination指的是当连接至某一数据库实例时，数据库无法找到其备用数据库的位置的错误。

官方解释

ORA-16076: unknown standby database destination

Cause: An attempt was made to start the physical standby database but the STANDBY_FILE_MANAGEMENT initialization parameter has not been set to AUTO.

Action: Set the STANDBY_FILE_MANAGEMENT initialization parameter to AUTO in the standby database and then startup mount the database.

此错误通常会在Oracle的Dataguard环境中出现。当客户尝试启动物理备用数据库时，STANDBY_FILE_MANAGEMENT初始化参数并未设为AUTO时就会出现此错误。

一般处理方法及步骤

1.确保物理备份数据库处于Mounted状态。

2. update the initialization parameter STANDBY_FILE_MANAGEMENT with the following SQL query:

ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT = AUTO;

3.启动重新启动物理备用数据库：

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE;
