常见案例
当我们在Oracle数据库归档日志时,如果在受影响的归档日志的目的地已经归档时,就会返回ORA-16091错误。
一般处理方法及步骤
1. 检查归档状态并写入到系统中,可以采用select * from V$ARCHIVED_LOG查询SHOW Archived为YES的数据,如果没有数据则说明日志没有归档。
2. 检查归档日志的依赖性,运行SELECT DISTINCT DEST_ID FROM V$ARCHIVE_DEST WHERE DEST_ID! = ‘-1’查看受影响的目标日志。
3. 如果检查到受影响的目标日志,则需要先删除这些依赖性,运行ALTER SYSTEM SET LOG_ARCHIVE_DEST_n=” WHERE n in(list of dependent archive logs);
4. 重新启动归档,ALTER SYSTEM SET LOG_ARCHIVE_DEST_1=’LOCATION=userenv,ENABLE=TRUE,MANDATORY=TRUE’;
5. 再次检查归档日志状态,select * from V$ARCHIVED_LOG;
6. 重新设置依赖性,ALTER SYSTEM SET LOG_ARCHIVE_DEST_n=” WHERE n in(list of dependent archive logs);
7. 启动监控日志。
