CAUSE
- The issue is caused when not using catalog database or no catalog connection is used.

SOLUTION
Option 1:- Using only the controlfile, no catlaog database used:
Use the below syntax from RMAN command prompt, for validating archivelog backups.
RMAN> restore archivelog from time='<RECOVERY WINDOWS DAYS#>' validate;
Suppose you have set the recovery window of 7 days, then use the below command.
RMAN> show RETENTION POLICY;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
RMAN> restore archivelog from time='SYSDATE-7' validate;

Option2: If you have recovery catalog configured, connect to target database and recovery catalog, and "RESTORE ARCHIVELOG ALL VALIDATE;" works without errors.
rman target / catalog <username>/<password>@<catalog_tns>
