1，添加/u03/script/oralin/fullbak.sh

#!/bin/sh
echo "`date` backup start"
$ORACLE_HOME/bin/rman target / nocatalog <<EOF
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup  format '/u03/dmp/oralin/dbfile/full%u_%s_%p' database
include current controlfile;
sql 'alter system archive log current';
backup filesperset 3 format '/u03/dmp/oralin/log/arch%u_%s_%p'
archivelog all delete input;
release channel c1;
release channel c2;
release channel c3;
}
EOF
echo "`date` backup successful"
exit;


2,添加/u03/script/oralin/delobsolete.sh

$ORACLE_HOME/bin/rman target / nocatalog <<EOFi
run{
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
}


3，crontab -e，添加：

00 03 * * * su - oracle -c "sh /u03/script/oralin/fullbak.sh">/u03/script/oralin/full.log
00 07 * * * su - oracle -c "sh /u03/script/oralin/delobsolete.sh">/u03/script/oralin/delobsolete.log
