2、安装数据库系统
3、安装nbu软件及配置
--安装客户端
上传SYMCnbclient_Linux-RedHat2.6.18_7.5.0.2.tar编辑本机hosts
vi /etc/hosts
添加:192.168.99.252 hdnbu1
解压:
[root@scmtest u01]# tar -xvf SYMCnbclient_Linux-RedHat2.6.18_7.5.0.2.tar[root@scmtest u01]# cd SYMCnbclient_Linux-RedHat2.6.18_7.5.0.2[root@scmtest SYMCnbclient_Linux-RedHat2.6.18_7.5.0.2]# ./install过程当中要输入备份服务端:hdnbu1
然后再用oracle用户执行:
[root@scmtest bin]# su - oracle
[oracle@scmtest ~]$ cd /usr/openv/netbackup/bin[oracle@scmtest bin]$ ./oracle_link

4、编辑初始参数文件
这时候,需要进行修改,比如原来用的什么盘,现在用什么盘等编辑后如下:
*._addm_auto_enable=FALSE
*._b_tree_bitmap_plans=FALSE
*._db_block_numa=1
*._enable_NUMA_optimization=FALSE
*._optimizer_cartesian_enabled=FALSE
*._optimizer_skip_scan_enabled=FALSE
*.archive_lag_target=1800
*.audit_file_dest='/software/oracle/admin/ncerp/adump'
*.background_dump_dest='/software/oracle/admin/ncerp/bdump'
*.compatible='10.2.0.5.0'
*.control_files='/u01/ncerp/control/control01.ctl','/u01/ncerp/control/control02.ctl'
*.core_dump_dest='/software/oracle/admin/ncerp/cdump'
*.db_block_size=8192
*.db_cache_size=4294967296
*.db_create_file_dest='/u01/ncerp/flash_recover'
*.db_domain=''
*.db_file_multiblock_read_count=16
*.db_name='ncerp'
*.java_pool_size=33554432
*.job_queue_processes=10
*.large_pool_size=33554432
*.log_archive_dest_1='location=/u01/ncerp/arch'
*.log_archive_format='%s_%t_%r.log'
*.max_dump_file_size='1024'
*.open_cursors=1000
*.optimizer_dynamic_sampling=4
*.optimizer_index_cost_adj=40
*.parallel_max_servers=5
*.pga_aggregate_target=2147483648
*.processes=800
*.recyclebin='OFF'
*.shared_pool_size=838860800
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
5、根据参数文件,建相应的目录
[oracle@scmtest ~]$ mkdir -p /u01/ncerp/control/[oracle@scmtest u01]$ mkdir -p /app/oracle/admin/ncerp/cdump[oracle@scmtest u01]$ mkdir -p /app/oracle/admin/ncerp/bdump[oracle@scmtest u01]$ mkdir -p /app/oracle/admin/ncerp/adump[oracle@scmtest u01]$ mkdir -p /app/oracle/admin/ncerp/pfile[oracle@scmtest u01]$ mkdir -p /u01/ncerp/flash_recover[oracle@scmtest u01]$ mkdir -p /u01/ncerp/arch[oracle@scmtest ncerp]$ mkdir oradata
注意:这些要与参数文件对应,要不然无法启动!
6、恢复控制文件
export ORACLE_SID=ncerp
[oracle@scmtest u01]$ rman target /

7、还原数据库文件
在这里要查一下数据库是否已经mount
SQL>select status from v$instance
STATUS
------------
MOUNTED
RMAN>run {
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE'
send 'NB_ORA_CLIENT=RD162'
set newname for datafile '/backup/ncerp/oradata/system01.dbf' to '/u02/ncerp/oradata/system01.dbf' set newname for datafile '/backup/ncerp/oradata/system02.dbf' to '/u02/ncerp/oradata/system02.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_index03_1.dbf' to '/u02/ncerp/oradata/nnc_index03_1.dbf'set newname for datafile '/backup/ncerp/oradata/undotbs1.dbf' to '/u02/ncerp/oradata/undotbs1.dbf' set newname for datafile '/backup/ncerp/oradata/sysaux01.dbf' to '/u02/ncerp/oradata/sysaux01.dbf' set newname for datafile '/backup/ncerp/oradata/users01.dbf' to '/u02/ncerp/oradata/users01.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data01_1.dbf' to '/u02/ncerp/oradata/nnc_data01_1.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data01_2.dbf' to '/u02/ncerp/oradata/nnc_data01_2.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data01_3.dbf' to '/u02/ncerp/oradata/nnc_data01_3.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data01_4.dbf' to '/u02/ncerp/oradata/nnc_data01_4.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data02_1.dbf' to '/u02/ncerp/oradata/nnc_data02_1.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data02_2.dbf' to '/u02/ncerp/oradata/nnc_data02_2.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data03_1.dbf' to '/u02/ncerp/oradata/nnc_data03_1.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data03_2.dbf' to '/u02/ncerp/oradata/nnc_data03_2.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data03_3.dbf' to '/u02/ncerp/oradata/nnc_data03_3.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data03_4.dbf' to '/u02/ncerp/oradata/nnc_data03_4.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_index02_1.dbf' to '/u02/ncerp/oradata/nnc_index02_1.dbf'set newname for datafile '/backup/ncerp/oradata/nnc_index01_1.dbf' to '/u02/ncerp/oradata/nnc_index01_1.dbf'set newname for datafile '/backup/ncerp/oradata/nnc_index01_2.dbf' to '/u02/ncerp/oradata/nnc_index01_2.dbf'set newname for datafile '/backup/ncerp/oradata/nnc_index01_3.dbf' to '/u02/ncerp/oradata/nnc_index01_3.dbf'set newname for datafile '/backup/ncerp/oradata/nnc_index01_4.dbf' to '/u02/ncerp/oradata/nnc_index01_4.dbf'set newname for datafile '/backup/ncerp/oradata/iufo01.dbf'to '/u02/ncerp/oradata/iufo01.dbf' set newname for datafile '/backup/ncerp/oradata/iufo02.dbf'to '/u02/ncerp/oradata/iufo02.dbf' set newname for datafile '/backup/ncerp/oradata/nnc_data03_5.dbf' to '/u02/ncerp/oradata/nnc_data03_5.dbf' Restore database
Switch datafile all
}
vi res_test.sh 内容如下:
export ORACLE_SID=ncerp
rman target / <run {
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE'
send 'NB_ORA_CLIENT=RD162'
做一次恢复测试看看
说明需要3556这个归档日志
所以恢复时,从这个日志进行恢复!
也可以采用后台运行方式
9、数据库恢复
SQL>
cancel
说明,如果上面日志可能有点大的时候,我们需要调整,比如说删除日志组等,然后还重新添加日志到新位置10、打开数据库
SQL>alter database open resetlogs
Database altered.
11、创建临时表空间
1.新建PFILE2.用pfile启动到MOUNT,恢复控制文件
3.根据控制文件恢复数据文件
4.resetlog打开数据库
大致流程就这样了!
