文档解释
ORA-01206: file is not part of this database – wrong database id
Cause: The database ID in the file header does not match the database id in the control file. The file may be from a different database, or it may not be a database file at all. If the database was rebuilt, this may be a file from before the rebuild. Note that if you see this error when the file is supposed to be plugged in from another database via the Transportable Tablespace feature, it means the database ID in the file header does not match the one expected.
Action: Restore a copy of the correct data file and do recovery as needed.
ORA-01206: file is not part of this database – wrong database id是一个Oracle数据库系统错误，意思是提供的文件不是当前数据库的一部分。
