Archive logs

Question

Hello All,
    I'm confused when it comes to archive logs. I did research the subject. The post at https://forums.oracle.com/thread/363272 somewhat
sounds like the problem I'm having. Our database goes down after a certain amount of time. We fix the problem by
issuing the commands:
                                       rman target /
                                       backup archivelog all delete input;
As far as I can tell, we are in archive log mode.
SQL> archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     6456
Next log sequence to archive   6458
Current log sequence           6458
This post mentioned something about automatic archive on. How do you check if automatic archive is on?  Or is this way off base?
Is there a way to backup the archive logs automatically without manually running the following:  rman target /
                                                                                                                                                        backup archivelog all delete input;
Thank you in advance. I really need to solve this problem soon. Any suggestions or explanations are greatly appreciated!

    I appreciate the information. Unfortunately, I am the programmer that became the DBA after attending Oracle DBA classes once. I am learning as I go. There are no implementation consultants. Thank you again
for the information.

Me again, Sharon. I appreciate your situation: I drifted into Oracle DBA work (decades ago...) without any porper training or mentor. Your classes should have covered the basics of backup and recovery, the ones I run (in-class and on-line) certainly do. But for the immediate future, I would suggest expanding your one line backup routine. Create a text file rman_script.txt with this content:
backup as compressed backupset database ;
backup as compressed backupset archivelog all delete all input;
backup current controlfile ;
delete obsolete;
And then run this every day:
rman target / @rman_script.txt
There is much more, but that should protect your database while you complete your studies.
Best of luck.
