ORA-19809: limit exceeded for recovery files

I often happen when the The Fast Recovery Area (FRA) is full with old archive log file  and so need to be emptied.
   Let's get in the RMAN

1. rman> connect target /
2. rman> crosscheck archivelog ALL;
3. rman> list expired archivelog ALL;
4. rman>DELETE expired archivelog ALL;
5. rman>delete archivelog all completed before 'SYSDATE-1';
6. rman>exit;

You may also like to adjust the size of the FRA:

 SQL> alter system set db_recovery_file_dest_size=10G;
 output:  system altered

You will be able to archive
SQL> archive log all;
output: 2 logs archived.
