Oracle produces many extraneous files: trace files, log files, dump files, and so on. Unless they are cleaned periodically, they can fill up the filesystem and bring the database to a halt.

To ensure that doesn't happen, simply search for the files with extension "trc" and remove them if they are more than three days old. A simple command does the trick:

find . -name "*.trc" -ctime +3 -exec rm {} \;
To forcibly remove them prior to the three-day limit, use the -f option.


find . -name "*.trc" -ctime +3 -exec rm -f {} \;
If you just want to list the files:

find . -name "*.trc" -ctime +3 -exec ls -l {} \;
