请大家给点建议。

西藏喇嘛

使用命令：  oerr ora 01157
01157, 00000, "cannot identify/lock data file %s - see DBWR trace file"
// *Cause:  The background process was either unable to find one of the data
//         files or failed to lock it because the file was already in use.
//         The database will prohibit access to this file but other files will
//         be unaffected. However the first instance to open the database will
//         need to access all online data files. Accompanying error from the
//         operating system describes why the file could not be identified.
// *Action: Have operating system make file available to database. Then either
//         open the database or do ALTER SYSTEM CHECK DATAFILES.

应该是数据文件有问题！！
