Oracle ORA0-00376 问题处理
ORA0-00376: "file '/data1/oradata/e_data1.dbf' cannot be read at this time"

重启数据库没有问题，数据文件都能打开。

[oracle@game ~]$ oerr ora 376
00376, 00000, "file %s cannot be read at this time"
// *Cause: attempting to read from a file that is not readable. Most likely
//          the file is offline.
// *Action: Check the state of the file. Bring it online
[oracle@game ~]$

经检查，操作系统下数据文件属性正常，磁盘空间正常。

怀疑数据文件有问题：

SQL> select file#,status from v$datafile;

     FILE# STATUS

---------- -------

         1 SYSTEM

         2 ONLINE

         3 ONLINE

         4 ONLINE

         5 RECOVER

         6 ONLINE

         7 ONLINE

         8 ONLINE

8 rows selected.

果然文件5状态为RECOVER，看来得手工恢复该文件了。

经确认，数据库未曾备份，但是归档重来没有删除过，恢复应该没有问题。
