ORA-12479: file label string must equal DBHIGH string
Cause: A database file had an OS label that did not match DBHIGH. Either DBHIGH was altered or the OS file was relabeled.
Action: Relabel the file so that its label matches DBHIGH, or alter DBHIGH so that it matches the label on the file.
ORA-12479错误是由于应用程序在备份或恢复数据库操作中的处理中输入的文件标签和给定的DBHIGH字符串不匹配导致的。
ORA-12479:file label string must equal DBHIGH string
Cause: The file label provided to the application with a backup or restore operation does not match the given DBHIGH string.
Action: Make sure that the file label string on the backup or restore operation command is exactly the same as the DBHIGH string.
ORA-12479的常见原因之一是将数据库恢复到不同的名称所提供的备份文件。由于DBHIGH和文件标签字符串不匹配，因此ORA-12479错误是可能出现的。
1. 确保备份文件的文件标签正确性。
2. 在恢复操作命令中，正确输入备份文件的文件标签字符串与提供的DBHIGH字符串完全匹配。
3. 使用Resetlogs恢复模式，重新创建新的日志文件，以消除任何标记上的不匹配。
4. 如果还是报Orav-12479错误，确保该操作的所有备份和恢复操作准确无误，然后重试操作。
