Oracle rac环境将datafile创建到本地文件系统的处理步骤
👉 本文共约382个字，系统预计阅读时间或需2分钟。
简介
oracle rac环境将datafile创建到本地文件系统，会造成间歇性访问异常。
若数据文件在节点1，而客户端访问连接的节点1，那么可以正常操作；而若数据文件在节点1，而客户端访问连接的节点2，那么此时就会报错：
1 2 | ORA-01157: cannot identify/lock data file 8 - see DBWR trace file ORA-01110: data file 8: '/home/oracle/a.dbf' |
实验
1 2 3 4 5 6 7 | sql "alter database datafile 8 offline"; recover datafile 8; run { copy datafile '/home/oracle/a.dbf' to '+data'; } run { switch datafile '/home/oracle/a.dbf' to datafilecopy '+DATA/gbk/datafile/test.302.1120761841'; } sql "alter database datafile 8 online"; |

总结
1、在rac中，在增加数据文件时，一定需要把数据文件放在共享存储中，否则会造成访问异常
2、在移动数据文件时，需要注意目标端是否已经含有相同的数据文件名，避免被覆盖。
