Recently I had a daily cron job fail to run on my system. When I ran it from the command line, I saw that it failed because it couldn't write to the full hard drive. I said, "What! No way!" df -h showed that it truly was very full. Then thanks to k4dirstat and xdiskusage, I was able to uncover that the real culprit was an excessive amount of these log_xxxx.xml files in oracle/base/diag/rdbms/instance1/instance1/alert. Can I just delete these? I've never needed to use them. How can I disable or get Oracle to produce less of them or do some kind of maintenance on them? If it's safe to just delete them, I can set up a cron job to just delete some of the older ones. I'd appreciate some guidance from someone who knows something about them. Thanks in advance.
