今天在测试环境中弄DG的时候出现了ORA-16072: a minimum of one standby database destination is required的报错:
环境如下:OS :RHEL 5.6 X86_64 DB:11.2.0.3.2 (单机)
原来是一个DG环境,由于备库已经损坏了,现在需要删除现有环境中的DG,重新搭建一个新的DG环境。在主库上面删除DG相关的参数、redo与相关的物理文件的。启动主库时就报错。后台日志如下:
- ARC0: Archival started
- LGWR: STARTING ARCH PROCESSES COMPLETE
- ARC0: STARTING ARCH PROCESSES

原因是由于原环境配置了FSFO,数据库在最大可性的模式下面,删除DG,需要修改数据库在最大性能下面。修改语法如下:
- sqlplus / as sysdba
- SQL> startup mount
- SQL> alter database set standby to maximize performance;
- SQL> alter database open;
修改后数据库启动正常。
