DataStage Server has no builtin compression functionality, but you can always shell out and execute UNIX or Windows commands such as gzip, compress or the command-line version of WinZip or WinRar or pkzip to mention just a few

Some database products, such as DB2 version 9, have inherent data compression capability.

here is the unix shell script for archival & compress the data files.


#!/bin/ksh
filename=/../../LocationFileList.txt ## this file containg files names wich need to archive & compress
filedir=/directory location
backupdir=/ ## where you want to put your archived files

## *** ARCHIVING Processing *** #####
cd $filedir
for i in `cat $filename | grep "^[A]" | cut -f1`;
do
act_filename=$i


DateTime=`date "+%Y%m%d%0H%M%S"`


mv $i $backupdir/$i"_"$DateTime

BackupPathAndName=$backupdir/$i"_"$DateTime

compress -v $BackupPathAndName

RC=$?
if [ $RC -ne 0 ]
then
echo "The file could not be Archived.\nPlease check the directory path."
# exit 139
fi

done

echo "Files have been archived and cleaned successfully"


## *** Versioning Process *** ##
if [ "$NumberOfBackups" = "" ]
then
NumberOfBackups=10
fi

cd $backupdir
for i in `cat $filename | grep "^[A]" | cut -f3`;
do

FileToBackupName=$i
VersionCount=`ls -l $FileToBackupName* | wc -l`

while [ $VersionCount -gt $NumberOfBackups ]
do
OldestFile=`ls -rt $FileToBackupName* | head -1`
rm -f $OldestFile

RC=$?
if [ $RC != 0 ]
then
echo "The file could not be deleted.\nPlease check the directory path."
# exit 139
fi
VersionCount=`expr $VersionCount - 1`
echo "\n Old versions (more than 10) removed in Backup Directory\n"

done
done
exit 0


Let me know you have any issues.

Thanks
