ORA-38776: cannot begin flashback generation – recovery area is disabled ORACLE 报错 故障修复 远程处理

文档解释

ORA-38776: cannot begin flashback generation – recovery area is disabled

Cause: During a database mount, the RVWR process discovered that the recovery area was disabled. DB_RECOVERY_FILE_DEST must have been set null or removed from the INIT.ORA file while the database was unmounted.

Action: Flashback database requires the recovery area to be enabled. Either enable the recovery area by setting the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE initialization parameters, or turn off flashback database with the ALTER DATABASE FLASHBACK OFF command.

ORA-38776表示无法开始回滚操作的快照生成,因为恢复区已被禁用。这是由于Oracle禁止以这种方式使用恢复区,因为它必须被用来执行恢复和数据库创建的操作。

为了解决这个错误,必须先启用恢复区。需要登录到Oracle数据库管理系统(DBMS),然后运行以下命令来启用恢复区:

ALTER DATABASE DATABASE RECOVERY AREA ENABLE;

随后,即可重试确认时间点恢复状态:

FLASHBACK DATABASE TO TIMESTAMP TO_DATE(‘YYYY-MM-DDTHH:MM:SS’,’YYYY-MM-DDTHH:MM:SS’);

欲了解更多信息,可查看Oracle文档中的以下语句:

ALTER DATABASE(https://docs.oracle.com/en/database/oracle/oracle-database/18/sqlrf/ALTER-DATABASE.html)

FLASHBACK(https://docs.oracle.com/en/database/oracle/oracle-database/18/sqpbt/FLASHBACK-DATABASE.html)
