文档解释

ORA-01248: file string was created in the future of incomplete recovery

Cause: Attempting to do a RESETLOGS open with a file entry in the control file that was originally created after the UNTIL time of the incomplete recovery. Allowing such an entry may hide the version of the file that is needed at this time. The file number may be in use for a different file which would be lost if the RESETLOGS was allowed.

Action: If more recovery is desired then apply redo until the creation time of the file is reached. If the file is not wanted and the same file number is not in use at the stop time of the recovery, then the file can be taken offline with the FOR DROP option. Otherwise a different control file is needed to allow the RESETLOGS. Another backup can be restored and recovered, or a control file can be created via CREATE CONTROLFILE.

该错误表明文件已创建，但存在未完成的恢复。

ORA-01248是由数据库管理员在数据库恢复期间尝试创建新文件所引起的Oracle错误。这种情况发生在实例启动以后可能已存在头文件，但数据库仍处于恢复模式。

ORA-01248通常发生在管理员正在执行备份/恢复过程时，该过程未完成时试图在ALTER DATABASE OPEN之前创建文件时发生。当尝试在此期间创建新文件时，该错误会发生。

正常处理方法及步骤

1.确定被尝试创建的文件，或将头文件添加到数据库中，以查看该文件是否已存在。

2.如果存在该文件，则根据错误提示，使用ALTER DATABASE OPEN RESETLOGS命令重新打开数据库。

3.如果不存在该文件，则可以重新尝试创建文件之前，或者在完成恢复过程后，将文件添加到数据库中。
