You will see under section 3) of that note a description.
The regular opatch util cleanup does not clean all that you want it seems.
I have written the following script, which you may use at your OWN RISK.
#!/bin/sh
# cleanup the patch storage for Opatch
# not all things are cleaned, so you may want to delete old patch directories that are backed up but not installed
# parameter: $ORACLE_HOME
if [ $# -ne 1 ];then
echo "Usage: clean_opatch_storage.sh
exit
else
OH=$1
fi
# where to put the rm commands
rmscript=/tmp/rmdirs.sh
echo > $rmscript
# show size before
du -s $OH/.patch_storage
# list contents
ls -l $OH/.patch_storage
# save inventory
$OH/OPatch/opatch lsinventory > /tmp/lsinv.log
export LOG=/tmp/lsinv.log
# list folders that are of patches:
cd $OH/.patch_storage
# make a list of the patch numbers in this directory
mylist=$(find . -mindepth 1 -maxdepth 1 -type d -name '*[0-9]*_*' -printf '%P\n' | awk '{split($0,a,"_"); print a[1]}' )
# check if those patches are in inventory log, if not remove the directory
for var1 in $mylist
do
FOUND=$(cat $LOG | grep -w $var1 | wc -l)
if [ $FOUND -eq 0 ]; then
echo $var1 Not found in inventory, so this directory should go
mydel=$(find . -mindepth 1 -maxdepth 1 -type d -name $var1'_*' -printf '%P\n' )
echo rm -rf $mydel >> $rmscript
else
echo $var1 Found in inventory, so this directory should be kept
fi;
done
# cat the script
echo This will be done:
cat $rmscript
read -r -p "Are you sure? [y/N] " response
case "$response" in
[yY][eE][sS]|[yY])
chmod 740 $rmscript
$rmscript

echo "Cancelled deletion!"
