==========================
# Export backup of bk schema*
if [ $# -le 0 ] ;then
echo please supply the passwd value in file \$1 as parameter
echo example see file \.ipmppass which has password replaced with xxxx
exit
fi
PASSWD=$1

rm -f bk.dmp.gz
rm -f bk.dmp

mknod bk.dmp p
split -b2047m < bk.dmp &
#gzip <bk.dmp> bk.dmp.gz &
exp SYSTEM/$PASSWD parfile=exp_bk.parfile
rm bk.dmp


exp SYSTEM/$PASSWD parfile=exp_bk.parfile
