1.RMAN 备份脚本

RUN {

 CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF  7  DAYS;

 CONFIGURE CONTROLFILE AUTOBACKUP ON;

 CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO "/backup/ZGW_Controlfile_%F";

 ALLOCATE CHANNEL CH1 DEVICE TYPE DISK;

 ALLOCATE CHANNEL CH2 DEVICE TYPE DISK;
 
 BACKUP DATABASE FORMAT "/backup/ZGW_%U"
     
     SKIP INACCESSIBLE FILESPERSET 10

     PLUS ARCHIVELOG FILESPERSET 20

     DELETE ALL INPUT;

 RELEASE CHANNEL CH1;

 RELEASE CHANNEL CH2;
 
 }

 BACKUP SPFILE FORMAT ‘/backup/ZGW_spfile_%U.bak‘; 
 
 ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE DISK;

 CROSSCHECK BACKUPSET;

 DELETE NOPROMPT OBSOLETE;

2.执行备份

 export ORACLE_SID=zgw
 rman target / @/home/oracle/scipts/rman_backup.rman

3.备份数据打包并传输

tar czvf zgw.tar.gz /ackup/ZGW*
scp zgw.tar.gz 192.168.199.68:/home/oracle/backup/

4.异机恢复环境准备

#环境变量
export ORACLE_SID=zgw
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=/opt/oracle/11g

#由于只安装软件未创建数据库所以需创建对应文件夹
mkdir -p $ORACLE_BASE/admin/zgw/adump/
mkdir -p $ORACLE_BASE/admin/zgw/dpdump/
mkdir -p $ORACLE_BASE/admin/zgw/pfile/
mkdir -p $ORACLE_BASE/oradata/zgw/
mkdir -p $ORACLE_BASE/flash_recovery_area
mkdir -p $ORACLE_BASE/flash_recovery_area/zgw

5.恢复操作

$ rman target /
