Oracle rman 备份日志单独备份和交叉校验

手动备份归档日志

1、database01

[oraprod@db01 scripts ]$ pwd
/usr/tivoli/scripts
[oraprod@db01 scripts ]$ ls
1.txt nohup.out oraicr0.sh scheoraicr0.sh
BKlog null oraicr1.sh scheoraicr0.sh.test
BKlog.tar oraarch.sh oraicr1.sh.orig scheoraicr1.sh
DBArchivelogBK.sh oraarch.sh.BK091206 oraicr1v.sh scheoraicr1.sh.test
DBArchivelogBK1130.sh oraarch.sh.yt oraicr2.sh scheoraicr1v.sh
DBFileBK_full.sh oraarch2.sh recover.sh scheoraicr2.sh
backup20130428.log oraarchyzz.sh refull.sh scheoraicr2.sh.test

nihao.sh orafull.sh.20120912combak schearch.sh.bak test.sh
nihao02.sh orafull.sh.BK091206 scheorafull.sh

[oraprod@db01 scripts ]$ rman target / catalog rman/rman@rman log = backup2013_05_01.log
RMAN>@oraarchyzz.sh

database 02

[oraprod@db02 archivelog ]$ pwd
/u01/archivelog
[oraprod@db02 archivelog ]$ cat backuparc.sql
run {
####backup archivelog####
allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/Oracle/bin64/tdpo.opt)'
connect backup/bk1949coal@PROD1;
allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)'
connect backup/bk1949coal@PROD2;
backup filesperset 10
(archivelog all skip inaccessible delete input format '/arch_%s_%p/');
release channel t1;
release channel t2;
}
[oraprod@db02 archivelog ]$ rman target / catalog rman/rman@rman log = backup20130501.log

PS:手动备份归档日志，每次都是从最近的归档日志开始备份，接在备份以前的，以前较早漏掉备份的可能每次执行都不会被备份。这样的话可能就要执行交叉检查命令来确认系统有多少备份日志成功备份，

crosscheck archivelog all;
crosscheck backupset;

进入rman：
list backup of archivelog all;
list backup of archivelog sequence 6474;

RMAN> list backup of archivelog from sequence 100425627276 thread 2;

RMAN>list backup of archivelog all; ------------列出所有归档日志
RMAN>list backup of archivelog from sequence 8116 thread 2; ------------列出某条归档日志

RMAN>

应该是归档日志备份后被删除了吧，没做交叉检验？
crosscheck archivelog all;

delete archivelog all completed before 'sysdate-7';
