If I remove the part that backups the logs, will I put it back in tomorrow? Will it still delete them out of my archive directory? Will it remove the references to the deleted ones? Or will it ask for them again after I put the backup line back in?

My archive log filesystem is on schedule to fill up tomorrow. (We keep getting more archive logs, none of them are being deleted.) I have searched and searched for a solution. I have found a couple of references to run this command from inside RMAN:

change archivelog all validate;

Will that fix it or make it worse? Thanks for your help, I'm getting a bit nervous.
