ORA-38856: cannot mark instance string (redo thread string) as enabled

ORA-38856
ORA-38856: cannot mark instance string (redo thread string) as enabled
Cause: The open resetlogs or standby activation operation failed because it needs
to mark an instance (redo thread) as enabled. However, it had less than 2 online
redo logs, which prevented it from being enabled.
Action: Add more logfiles to the specified instance and retry the command.
