As my username suggests, I'm more familiar with Informix than Oracle. I administer over 14 Informix instances here, and I have a few Oracle instances that I must maintain, also.

In doing so, I've found that there are alot of archived log files (over 2yrs old) in the $ORACLE_HOME/admin/$SID/arch dir. I'm fairly sure most of these log files are not needed for recovery, and I'd like to delete them.

Is deleting them with the unix "rm" command, the proper way to do so? Or does Oracle recommend a better way? I could not find any documentation on the removal of these files. Thanks for your help.
