Oracle
备份恢复文档
(V1.0)
-
安装networker客户端
在需要进行恢复的机器上,安装networker客户端,且在netwoker服务端添加client。
详情参照《Oracle11.2.0.4安装手册》6.2章节。
-
恢复参数文件
建一个简化版的spfile,名为initjxdsjkp.ora (init+实例名)
将数据库启动到nomount状态
从备份集中还原参数文件
设置dbid:
set dbid=1774519710;
恢复spfile脚本:
run
{
allocate channel t1 type \'SBT_TAPE\';
send \'NSR_ENV=( NSR_CLIENT=jxdsjkdbp02,NSR_SERVER=networker,NSR_DATA_VOLUME_POOL=orapool)\';
restore spfile to \'/u01/app/oracle/product/11.2.0/db/dbs/spfilejxdsjkp.ora\' from autobackup;
release channel t1;
}
NSR_CLIENT需要指定你要恢复的数据库networker的client名。
还原参数文件后,重启一下实例,启动到nomount;
3.恢复控制文件
Networker查看spfile所在的备份集(参数文件和控制文件都在同一个备份集c-打头)
恢复脚本:
set dbid=1774519710;
run
{
allocate channel t1 type \'SBT_TAPE\';
send channel t1 \'NSR_ENV=( NSR_CLIENT=jxdsjkdbp02,NSR_SERVER=networker,NSR_DATA_VOLUME_POOL=orapool)\';
restore controlfile from \'c-1774519710-20210617-00\';
release channel t1;
}
-
恢复数据文件
数据库启动到mount
恢复脚本:
因为是异机恢复,路径不一致所以需要SET NEWNAME FOR和SWITCH 等操作。
RUN
{
allocate channel t1 type \'SBT_TAPE\';
allocate channel t2 type \'SBT_TAPE\';
allocate channel t3 type \'SBT_TAPE\';
allocate channel t4 type \'SBT_TAPE\';
send \'NSR_ENV=( NSR_CLIENT=jxdsjkdbp02,NSR_SERVER=networker,NSR_DATA_VOLUME_POOL=orapool)\';
SET NEWNAME FOR DATAFILE 4 to \'/oradata/jxdsjkp/users01.dbf\';
SET NEWNAME FOR DATAFILE 3 to \'/oradata/jxdsjkp/undotbs01.dbf\';
SET NEWNAME FOR DATAFILE 2 to \'/oradata/jxdsjkp/sysaux01.dbf\';
SET NEWNAME FOR DATAFILE 1 to \'/oradata/jxdsjkp/system01.dbf\';
SET NEWNAME FOR DATAFILE 5 to \'/oradata/jxdsjkp/datahup01.dbf\';
SET NEWNAME FOR DATAFILE 6 to \'/oradata/jxdsjkp/datahup02.dbf\';
SET NEWNAME FOR DATAFILE 7 to \'/oradata/jxdsjkp/datahup03.dbf\';
SET NEWNAME FOR DATAFILE 8 to \'/oradata/jxdsjkp/datahup04.dbf\';
SET NEWNAME FOR DATAFILE 9 to \'/oradata/jxdsjkp/datahup05.dbf\';
SET NEWNAME FOR DATAFILE 10 to \'/oradata/jxdsjkp/datahup06.dbf\';
set newname for tempfile 1 to \'/oradata/jxdsjkp/temp01.dbf\';
RESTORE DATABASE;
SWITCH DATAFILE ALL;
SWITCH TEMPFILE ALL;
RECOVER DATABASE;
release channel t1;
release channel t2;
release channel t3;
release channel t4;
}
本机恢复脚本:
Run{
allocate channel t1 type \'SBT_TAPE\';
allocate channel t2 type \'SBT_TAPE\';
allocate channel t3 type \'SBT_TAPE\';
allocate channel t4 type \'SBT_TAPE\';
send \'NSR_ENV=( NSR_CLIENT=jxdsjkdbp02,NSR_SERVER=networker,NSR_DATA_VOLUME_POOL=orapool)\';
RESTORE DATABASE;
RECOVER DATABASE;
release channel t1;
release channel t2;
release channel t3;
release channel t4;
}
-
修改redo文件位置
异机恢复(路径不同):
alter database rename file \'/oracle/database/oradata/jxdsjkp/redo01.log\' to \'/oradata/jxdsjkp/redo01.log\';
alter database rename file \'/oracle/database/oradata/jxdsjkp/redo02.log\' to \'/oradata/jxdsjkp/redo02.log\';
alter database rename file \'/oracle/database/oradata/jxdsjkp/redo03.log\' to \'/oradata/jxdsjkp/redo03.log\';
原机恢复不需要上述操作。
-
启动数据库
Alter database open resetlogs;
