Archivelog Space Filled up or Archivelog is 100% full | Oracle Database

The following opinions expressed in this post are my own and in no way connected to my employer. 

Issue:

You may see an error message in Database Alert log regarding Archive Log Space getting 100% filled.

Solution:

Try below to delete archivelogs or cleanup space or to increase allocated space:

Delete Expired Archivelogs:

rman target /

crosscheck archivelog all;

delete expired archivelog all;

crosscheck backup;

Delete Archivelogs older than 30 days:

rman target /

run{ 

allocate channel c1 type disk; 

delete force noprompt archivelog until time 'SYSDATE-30'; 

release channel c1; 

} 

You can also increase space allocated to avoid the error, but check if you have diskspace available to do so:

alter system set db_recovery_file_dest_size=200G scope=both;
