This step is to set current workspace for all the following commands. It will be a boring job to clean them one by one if you do not use ADRCI. In this case, a RAC envrionment, I have 8 ARD homes. List All Homes of Trace FilesДЄs I said, there are several kinds of trace file located at various ADR homes. It could be the best tool to do the tedious job.

Here in this post, I recommend you to use ADRCI command interface to control over these trace files. Please note that auditing files and the alert log are not included in trace files by definition, you have to find an integrated way to delete all trace logs, audit files, alert log and so on. For the alert log, it's a little different, you can delete or trim it for reducing the size of the file. Their filename extensions usually are *.trc, *.trm or *.log. Trace files include core dump, user dump and background dump from grid, rdbms or listener. But cleaning trace files may become a hard work, because the trace files belongs to various logging purposes and they are scattered all over the database server, it may cost you a lot of time to find them and delete trace files. Trace files have to be controlled and cleaned regularly, otherwise your disk space will be exhausted soon or later.
