文档解释

ORA-63002: a data file copy that is not current

Cause: An obsolete copy of a data file left from a data file move operation was used for the CREATE CONTROLFILE command or file header read.

Action: Pass a valid file or perform a media recovery on the file.

ORA-63002：当某个数据库文件被拷贝而发生冲突时，显示该错误信息。

官方解释

ORA-63002：该数据库文件可能是由另一个拷贝引起，而它不是当前拷贝。

常见案例

1、在ORACLE的RMAN备份中，可能会出现ORA-63002的情况。

2、在数据库的备份和更新操作中，使用到多个拷贝的过程中，也可能出现ORA-63002的情况。

一般处理方法及步骤

1、先查看日志，明确拷贝是否产生了冲突。

2、如果发现冲突，则需要使用备份策略进行处理，如替换原有拷贝，或者重新拷贝文件。

3、想要从根本上解决该问题，需要调整Oracle数据库的备份策略，减少不必要的拷贝流程。
