Networker oracle备份恢复

Oracle

备份恢复文档

（V1.0）

 

 

 

 

 

 

 

 

 

 

1. 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https://www.cnblogs.com/muzisanshi/p/14921431.html  6.2章节。

2. 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;

   }

    

   

3. 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;

   }

4. 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。

5. 启动数据库

   Alter database open resetlogs;
