To: Multiple recipients of list ORACLE-L
there is a note out on Metalink on how to do this. You can also break the
export into separate files in later versions of Oracle8i. or you can run the
following script (modified to suit your system, it was last tested on
Solaris/Oracle 7.3.4)
#!/bin/sh
#
cd $EXPORT_DIR
#
# set maximum file size for each chunk of the export file
#
MAXFILESIZE=2000m
export MAXFILESIZE
#
# create filenames for the parts of the backup... for now let's go to 3
#
FILENAME1=$EXPORT_DIR/backup1_$ORACLE_SID.dmp
FILENAME2=$EXPORT_DIR/backup2_$ORACLE_SID.dmp
FILENAME3=$EXPORT_DIR/backup3_$ORACLE_SID.dmp
LOGFILE=$EXPORT_DIR/backup_$ORACLE_SID.log
#
# save off the old ones
#
mv $FILENAME1 $FILENAME1.old
if [ -f $FILENAME2 ]
then
mv $FILENAME2 $FILENAME2.old
fi
if [ -f $FILENAME3 ]
then
mv $FILENAME3 $FILENAME3.old
fi
mv $LOGFILE $LOGFILE.old
#
# create the pipes
#
mkfifo exportpipeaa
mkfifo exportpipeab
mkfifo exportpipeac
mkfifo wrkpipe
umask 000
#
# start the readers from the pipes to create the export files
#
dd if=exportpipeaa of=$FILENAME1 &
dd if=exportpipeab of=$FILENAME2 &
dd if=exportpipeac of=$FILENAME3 &
#
# start the reader from the wrkpipe to compress and split the export
#
dd if=wrkpipe|compress|split -b $MAXFILESIZE - exportpipe &
#
# start the export for real
#
exp "/" file=wrkpipe full=y compress=n buffer=4096000 LOG=$LOGFILE
#
# 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
now to import from those split files"
#!/bin/sh
#
cd $EXPORT_DIR
#
# create filenames for the parts of the backup... for now let's go to 3
#
FILENAME1=$EXPORT_DIR/backup1_$ORACLE_SID.dmp
FILENAME2=$EXPORT_DIR/backup2_$ORACLE_SID.dmp
FILENAME3=$EXPORT_DIR/backup3_$ORACLE_SID.dmp
LOGFILE=$EXPORT_DIR/backup_$ORACLE_SID.log
#
# create the pipe to import from
#
mkfifo wrkpipe
umask 000
#
# start the reader from the import pipe
#
imp "/" file=wrkpipe full=y commit=y buffer=4096000 LOG=$LOGFILE &
#
# create the import stream coming from the pipes
#
cat $FILENAME1 $FILENAME2 $FILENAME3 | uncompress | dd of=wrkpipe
#
# clean up the import pipe
#
rm wrkpipe
