恢复步骤:
0,在sit环境修改原库的db_name为dm环境db_name,数据文件路径。
把备份文件放到'/stg/oracle/ot11g/ot11g/yhw
1, 启到nomount状态,恢复控制文件:
catalog start with '/stg/oracle/ot11g/ot11g/yhw';
rman target /
restore controlfile from '备份路径/rman备份的控制文件';
sql 'alter database mount';
2,以下是恢复脚本,如果db比较小,可以直接用4个channel
因为是异机恢复,必须使用set newname来替换本机
在源库执行
select 'set newname for datafile '||file# || ' to '||''''||&1||'/'||substr(name,instr(name,'/',-1)+1)||''''||';' from v$datafile_header;
输入目标库的DG:直接输入’'+TESTDATA_DG'
例子如下
z4ci1011:fcrtest1 > cat restore.sh
export log_file=/paic/app/oracle/fcrrman/fcrtest_rman/fcr_rman_backup_20120710/restore_${ORACLE_SID}_`date '+%Y%m%d_%H%M%S'`.log
rman target / << EOF > ${log_file} 2>&1
run
{

allocate channel c2 type disk ;
allocate channel c3 type disk ;
allocate channel c4 type disk ;
allocate channel c5 type disk ;
allocate channel c6 type disk ;
allocate channel c7 type disk ;
allocate channel c8 type disk ;
allocate channel c9 type disk ;
allocate channel c10 type disk ;
allocate channel c11 type disk ;
allocate channel c12 type disk ;
set newname for datafile 1 to '+TESTDATA_DG';
set newname for datafile 2 to '+TESTDATA_DG';
set newname for datafile 3 to '+TESTDATA_DG';
set newname for datafile 5 to '+TESTDATA_DG';
set newname for datafile 6 to '+TESTDATA_DG';
set newname for datafile 7 to '+TESTDATA_DG';
set newname for datafile 8 to '+TESTDATA_DG';
set newname for datafile 9 to '+TESTDATA_DG';
set newname for datafile 10 to '+TESTDATA_DG';
set newname for datafile 11 to '+TESTDATA_DG';
set newname for datafile 12 to '+TESTDATA_DG';
set newname for datafile 13 to '+TESTDATA_DG';
set newname for datafile 14 to '+TESTDATA_DG';
set newname for datafile 15 to '+TESTDATA_DG';
set newname for datafile 16 to '+TESTDATA_DG';
set newname for datafile 17 to '+TESTDATA_DG';
set newname for datafile 18 to '+TESTDATA_DG';
set newname for datafile 19 to '+TESTDATA_DG';
set newname for datafile 20 to '+TESTDATA_DG';
set newname for datafile 21 to '+TESTDATA_DG';
set newname for datafile 22 to '+TESTDATA_DG';
set newname for datafile 23 to '+TESTDATA_DG';
restore database;
switch datafile all;
recover database;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
release channel c5 ;
release channel c6 ;
release channel c7 ;
release channel c8 ;
release channel c9 ;
release channel c10;
release channel c11;
release channel c12;
}
EOF
echo "Restore finished at `date '+%Y%m%d_%H%M%S'`" >> ${log_file}
z4ci1011:fcrtest1 >
3,恢复完成后,要做open read only验证
4, 就是启库流程了
log_file=/paic/bank/tmpsun/rman1/backup/DM7/dmbcmsm/restore_${ORACLE_SID}_`date '+%Y%m%d_%H%M%S'`.log
export log_file
rman target / << EOF > ${log_file} 2>&1
run
{
allocate channel c1 type disk ;
allocate channel c2 type disk ;
allocate channel c3 type disk ;
allocate channel c4 type disk ;
allocate channel c5 type disk ;
allocate channel c6 type disk ;
allocate channel c7 type disk ;
allocate channel c8 type disk ;
restore database;
switch datafile all;
recover database;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
release channel c5 ;
release channel c6 ;
release channel c7 ;
release channel c8 ;
}
EOF
echo "Restore finished at `date '+%Y%m%d_%H%M%S'`" >> ${log_filei}
