Home -> Community -> Mailing Lists -> Oracle-L -> RE: Export bigger then 2G with Oracle7.3.4
I've uses the UNIX split command successfully with Oracle 7.3.4:
# set maximum file size for each chunk of the export file
#
MAXFILESIZE=1500m
export MAXFILESIZE
#
# create filenames for the parts of the backup
#
FILENAME1=$BACKUP_DIR/exporthrprd1.dmp FILENAME2=$BACKUP_DIR/exporthrprd2.dmp FILENAME3=$BACKUP_DIR/exporthrprd3.dmp
#
# create the pipes
#
mkfifo exportpipeaa
mkfifo exportpipeab
mkfifo exportpipeac
mkfifo wrkpipe
umask 000
#
# start the readers from the pipes to create the export files
#
dd if=exportpipeaa of=$FILENAME1 & dd if=exportpipeab of=$FILENAME2 & dd if=exportpipeac of=$FILENAME3 &
#
# start the export for real
#
$ORACLE_HOME/bin/exp / FILE=wrkpipe OWNER=SYSADM DIRECT=Y BUFFER=5120000
LOG=$LOGFILE
#
# check return code from export
#
RetCode=$?
if [ ${RetCode} -ne 0 ]
then
echo $(date +%Y%m%d-%H%M%S) ${script} --WARNING-- export for
${ORACLE_SID} failed >> ${BACKUP_DIR}/expsplit.log
#echo $(date +%Y%m%d-%H%M%S) ${script} --ERROR-- export for
${ORACLE_SID} failed
#exit 1
fi
#
# clean up after ourselves
#
rm exportpipeaa exportpipeab exportpipeac wrkpipe
#
# if you haven't used all the pipes, the dd may still linger on
# make sure to REALLY clean up
#
ps -ef|grep exportpipe|grep -vi grep|awk '{printf ("kill -9 %d;
\n",$2)}'>kill.lst
chmod u+x kill.lst
sh kill.lst
rm kill.lst

You could migrate the database to 8i, or you could use sql to split the table into 2GB and do the export in pieces, or you could just shut the database down and do a cold backup of the database, retaining any media you need to reinstall Oracle 7. Make sure if you are in archivelog mode that you backup all logfiles.

Hi DBAs,
Because of some requirements from one of our vendor, we still have a database running Oracle7.3.4 on WindowsNT and since this package is no longer used, so we want to export the content of this database. The database is around 60G, one table is 55G. So a simple export on release 7 will crash when I will get 2G of dump file.
The export utility for release 7 doesn't allow us to create multiple files, but the export utility for release 8 does. I know that they recommend to always use the lower version of export, but is there a way to use export 8i and create multiple files on a Oracle7.3.4 database?
If not, what can I do?
Thanks
Luc
