linux如何移动数据到文件系统,怎么把数据文件从文件系统移动到asm？

發布時間：2023/12/19 linux 43 豆豆

生活随笔收集整理的這篇文章主要介紹了 linux如何移动数据到文件系统,怎么把数据文件从文件系统移动到asm？小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

看到itpub里有人誤操作把rac文件建立在文件系統上了！具體操作如下：

oral31> alter tablespace system add datafile '/u01/crs/oracle/system02.dbf' size 10m;

Tablespace altered.

oral31> select name from v$datafile;
