DB2/6000 - When Can I rm a log file and how to automate the process

DESC:
  I am using archive logging and would like to know when I can 
  remove my old logs.  
 .
  QUESTIONS
  ==========
  What is the rule of thumb on this?
  Can I remove these logs from the user exit program?
  If not what is an alternative?
 .
ACTION:
  RULE of THUMB
  ==============
  1. Keep all logs since your last backup.
  2. From those logs which are older than your last backup keep 
     only the logs that go back to the furtherest point to which
     you may have cause to roll back.

  You can remove the files from the user exit program if you 
  choose to rewrite the program to do this. 

  Following is a fairly short script to remove old files.  It will
  do very basic error checking and will only remove files.  A log is 
  kept if the files which are being removed.  The script is inclosed 
  below:

______________________ .rmdata ________________________________________
\#! /bin/ksh

typeset -i DAYS

usage()
{  print "     Usage: .rmdate -p {Absolute Directory Path} -d days"
  print "            example to remove files older than 4 days in /tmp"
  print "            .rmdate -p /tmp -d 4"
}
if [ "$\#" -ne 4 ]
then
  usage
  exit 1
fi

while [ "$\#" -ne 0 ]
do
  case "$1" in

        -p) STORAGE=$2
            if [ ! -d ${STORAGE} ]
            then
               print "Directory does not exist"
               exit 1
            fi
            shift; shift;;

        -d) DAYS=$2
            shift; shift;;

        *)  echo "Invalid flag"
            usage
            exit 2
  esac
done

cd  ${STORAGE}
print "The following files were removed on `date`" > /archive_rm.log
find ${STORAGE} -type f -print -ctime +${DAYS} -exec /bin/ls -l {} \\; \\
  >> /archive_rm.log
find ${STORAGE} -type f -print -ctime +${DAYS} -exec /bin/rm -f {} \\; \\
  1> /dev/null

exit 0
