Lee -----Original Message----- Sent: 16 May 2001 22:28 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 >From: "Armstead, Michael A" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> >Subject: RE: Export Split Script >Date: Wed, 16 May 2001 13:07:24 -0800 > >Rajaram, > >Please give me details on how to use mknod to split export files larger >than >2 GB.
