********************* ATTENTION: ******************** 
 The controlfile header block returned by the OS
 has a sequence number that is too old. 
 The controlfile might be corrupted.
 PLEASE DO NOT ATTEMPT TO START UP THE INSTANCE 
 without following the steps below.
 RE-STARTING THE INSTANCE CAN CAUSE SERIOUS DAMAGE 
 TO THE DATABASE, if the controlfile is truly corrupted.
 In order to re-start the instance safely, 
 please do the following:
 (1) Save all copies of the controlfile for later 
     analysis and contact your OS vendor and Oracle support.
 (2) Mount the instance and issue: 
     ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
 (3) Unmount the instance. 
 (4) Use the script in the trace file to
     RE-CREATE THE CONTROLFILE and open the database.

根据上述报错信息可以确认报错的是一个index,而且非系统核心对象,可以通过allow 1 corruption方式进行恢复,并且open库成功

SQL> recover  datafile 1 allow 1 corruption;
