$ more bkup_proarc.rman
run {
allocate channel aaa device type sbt;

backup
     filesperset 40
     format ‘al_%s_%p_%t‘
     archivelog all delete input;

}
$ more bkup_orapro.rman
run {

allocate channel c2 device type sbt;

     archivelog all delete input;
backup current controlfile;
release channel c1;
release channel c2;
}
$ more delete.rman
run {
delete noprompt obsolete;
}


另外一种备份方式：
[[email protected] db]$ more /script/fullback.sh
#!/bin/sh
export ORACLE_HOME=XXX
export ORACLE_SID=XXX
$ORACLE_HOME/bin/rman log=XXX/fullback.log <<EOF
connect target / 
connect catalog rman/[email protected]
run{
allocate channel ‘d1‘ type disk;
allocate channel ‘d2‘ type disk;
allocate channel ‘d3‘ type disk;
backup incremental level=0 database format=‘XXX/%U.bak‘ tag=‘full_bak‘;
sql ‘alter system archive log current‘;
backup format ‘XXX/log/%U.bak‘ archivelog from time ‘sysdate-7‘;
DELETE noprompt ARCHIVELOG ALL COMPLETED BEFORE ‘sysdate-7‘;
release channel d1;
release channel d2;
release channel d3;
}
exit;
EOF

[[email protected] db]$ more XXX/deleteback.sh
#!/bin/sh
export ORACLE_HOME=XXX
export ORACLE_SID=XXX
$ORACLE_HOME/bin/rman log=XXX/deleteback.log <<EOF
connect target / 
connect catalog rman/[email protected]
run{
crosscheck backup;
delete noprompt obsolete;
}
exit;
EOF



windows平台备份脚本（需测试）：
RUN {
 allocate channel c1 type disk;
 backup database format ‘c:/rman_backup/db_%U‘ plus archivelog format ‘c:/rman_backup/arch_%U‘;
 release channel c1;
 }
