ORA-38701 ORA-27037 when select * from v$restore_point;

When trying to find the name of a restore point that has one or all of its flashback logs not available you will get this error:

SQL> select * from v$restore_point;
select * from v$restore_point
              *
ERROR at line 1:
ORA-38701: Flashback database log 112 seq 10593 thread 1: "/fra/ERDB/flashback/o1_mf_gbd00tqk_.flb"
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

You have to get the restore point name from RMAN which read the details from the controlfile instead of the dictionary:

RMAN> list restore point all;
using target database control file instead of recovery catalog
SCN              RSP Time  Type       Time      Name
---------------- --------- ---------- --------- ----
6418212255444              GUARANTEED 01-JUL-19 TEMP

Drop the restore point from SQLPLUS:
SQL> drop restore point temp;

Unable to Drop a REDOLOG Group ORA-00313 ORA-27037 No such file or directory

Cannot drop a standby redo logfile group because its files were already deleted on OS:

SQL> alter database drop standby logfile group 26;
alter database drop standby logfile group 26

ERROR at line 1:
ORA-00313: open failed for members of log group 26 of thread 2
ORA-00312: online log 26 thread 2: '/data01/awsdev2/datafiles/group_26.273.968987155'

Fix:

Re-populate the logfile members inside this group:

SQL> alter database clear unarchived logfile group 26;

Database altered.

Now you can drop the standby redolog group:

SQL> alter database drop standby logfile group 26;

Database altered.
