症状

~~~~~~~~~~

你看到以下错误之一:

 

ORA-01115: IO error reading block from file ? (Block # ?)

ORA-01110: data file ?: ‘<filename>’

ORA-27091: skgfqio: unable to queue I/O

ORA-27069: skgfdisp: attempt to do I/O beyond the range of the file

 

 

ORA-01113: file ? needs media recovery

ORA-01110: data file ?: ‘<filename>’

 

 

ORA-01122: database file ? failed verification check

ORA-01110: data file ?: ‘<filename>’

ORA-01251: Unknown File Header Version read for file number ?

 

 

更改

~~~~~~~~~~

在你发出以下命令后看到这些错误:

 

ALTER DATABASE RENAME FILE ‘<filename>’ TO ‘<filename>’;

 

 

原因

~~~~~~~

重命名数据文件的正确步骤是

 

1) 使数据文件脱机,或使表空间脱机,或使数据库在mount模式

 

2) 将新文件复制到其适当的位置。

 

3) 发出命令:

ALTER DATABASE RENAME FILE ‘<filename>’ TO ‘<filename>’;

 

4) 更改alter数据文件联机(可能需要文件恢复),或alter表空间联机,或打开数据库。怎么做取决于你在步骤1中执行了什么行为。

 

 

你在步骤2,即复制步骤中的行为都可能导致这些错误,如下所述。

 

 

如果在步骤2中你使用Unix “touch”命令来创建新的文件而没有复制文件,你会看到以下错误:

 

ORA-01115: IO error reading block from file ? (Block # ?)

ORA-01110: data file ?: ‘<filename>’

ORA-27091: skgfqio: unable to queue I/O

ORA-27069: skgfdisp: attempt to do I/O beyond the range of the file

 

修正

~~~~

复制被重命名的正确文件到新文件名。不要使用Unix的touch命令来创建新的文件。在你将新文件名复制到正确文件后,你就能alter数据文件联机。

 

 

如果你复制了被重命名的文件的旧版本而不是最新的版本,你会看到以下错误:

 

ORA-01113: file ? needs media recovery

ORA-01110: data file ?: ‘<filename>’

 

修正

~~~~

复制被重命名的文件的最新的版本而不是旧版本。或者,如果你的数据库在归档日志模式下且你有所有的归档日志文件,恢复数据文件。在你将正确文件的最新版本到新文件名后,你就能alter 数据文件联机。

 

 

 

如果你将错误文件复制到新文件名,你会看到以下错误:

 

ORA-01122: database file ? failed verification check

ORA-01110: data file ?: ‘<filename>’

ORA-01251: Unknown File Header Version read for file number ?

 

作为示例,我们假设你想要为用户的表空间重命名一个文件。

你进行以下操作:

1)  ALTER TABLESPACE USERS OFFLINE;

2)  cp tools1.dbf users1.dbf

3)  ALTER DATABASE RENAME FILE ‘/u01/oradata/users01.dbf’ to ‘/u01/oradata/users1.dbf’

4)  ALTER TABLESPACE USERS ONLINE.

 

*   ORA-01122, ORA-01110, ORA-01251 returned.

 

修正

~~~~

在步骤二中将正确文件复制到新文件名。以下是你应该执行的步骤:

 

1)  ALTER TABLESPACE USERS OFFLINE;

2)  cp users01.dbf users1.dbf

3)  ALTER DATABASE RENAME FILE ‘/u01/oradata/users01.dbf’ to ‘/u01/oradata/users1.dbf’

4)  ALTER TABLESPACE USERS ONLINE.

 

在将正确文件复制到新文件名后,你应该能够alter数据文件联机。
