ERROR: ORA-00600: internal error code, arguments: [3020] recovery detected a data block with invalid SCN. This could be caused by a lost write on the primary; do NOT attempt to bypass this error by copying blocks or datafiles from the primary database to the standby database because that would propagate the lost write from the primary to the standby.

*****************************************************************
An internal routine has requested a dump of selected redo.
This usually happens following a specific internal error, when
analysis of the redo logs will help Oracle Support with the
diagnosis.
It is recommended that you retain all the redo logs generated (by
all the instances) during the past 12 hours, in case additional
redo dumps are required to help with the diagnosis.

Background Media Recovery process shutdown (TESTDB1)没有修复
那么从主库把sysaux单独恢复至备库
思路：
1、从主库中backup as copy（映像副本）所需文件至本地 【备份集（backup datafile）catalog backuppiece】
2、将文件传至备库本地文件系统
3、备库文件cp至共享存储
4、删除原文件，进行恢复
主库备份sysaux数据文件
