Referred to a different operation after reducing machine rman
After the reduction was far from the main library test library by rman backup because the backup is in standby database backup, database restore state after it is readonly, standby_file_management parameter is auto.
First need to alter database clear logfile group log group; let the database creates a log file on disk.
1 problems, physical redo log file does not exist, then log Group 4 state current, can not be changed operate in readonly mode. Issue 2, and does not correspond to undo tablespace control file parameter file
