[oracle@oracle ~]$ oerr ora 01200
01200, 00000, "actual file size of %s is smaller than correct size of %s blocks"
// *Cause: The size of the file as returned by the operating system is smaller
// than the size of the file as indicated in the file header and the
// control file. Somehow the file has been truncated. Maybe it is the
// result of a half completed copy.
// *Action: Restore a good copy of the data file and do recovery as needed.
數據文件實際塊數小於數據文件頭部記錄的數據文件塊數
二 用bbed構造一個ora-01200錯誤
1 數據文件/oracle/test/jiujian1.dbf實際佔用塊數如下:
FILE_NAME BLOCKS
---------------------------------------- ---------
/oracle/test/jiujian1.dbf 1048
2 用bbed修改數據文件頭部記錄的數據文件佔用塊數

3 啓動數據庫便可觸發ora-01200錯誤

ORA-01200: actual file size of 1048 is smaller than correct size of 1049 blocks
三ora-01200錯誤的解決
方式1 通過bbed 改數據文件頭部偏移量44處的值爲數據文件實際佔用塊數
方式2 通過dd命令填充數據文件實際大小爲correct size of 1049 blocks中的值
dd if=/dev/zero of=/oracle/test/jiujian1.dbf bs=8192 count=1 seek=1049
