由 dawei 副标题#e#
基础环境:
- 172.17.4.60 操作系统:Linux 6.4 数据库:Oracle11gR2 (源数据库)
- 172.17.4.61 操作系统:Linux 6.4 数据库:Oracle11gR2 (测试库)
目的:从源数据库以RMAN的物理恢复的方式，恢复至测试库中。
如何验证，在源数据库，插入几条数据如下:
[email?protected]> create user zsd identified by zsd;
User created.
[email?protected]> grant dba to zsd;
Grant succeeded.
[email?protected]> conn zsd/zsd;
Connected.
[email?protected]> create table t1(name varchar2(20));
Table created.
[email?protected]> insert into t1 values('zsd');
1 row created.
[email?protected]> insert into t1 values('lzh');
1 row created.
[email?protected]> insert into t1 values('zjf');
1 row created.
[email?protected]> commit;
Commit complete.
[email?protected]> select * from t1;
NAME
--------------------
zsd
lzh
zjf
Step 0.基础环境的host配置
两台服务器都需要做如下配置。
[[email?protected] ~]$ cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.17.4.60 db1 172.17.4.61 db2
源数据库端(172.17.4.60):
[[email?protected] ~]$ cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=db1
测试数据库端(172.17.4.61):
[[email?protected] ~]$ cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=db2
Step 1.修改环境变量
[[email?protected] dbs]$ cd ~ [[email?protected] ~]$ vi .bash_profile
修改ORACLE_SID与源数据库一致，如下:
ORACLE_SID=oradb
Step 2.建立pfile dummy文件
[o[email?protected] ~]$ cd $ORACLE_HOME/dbs [[email?protected] dbs]$ vi dummy.ora db_name='zsddummy'
Step 3.从源数据库(172.17.4.60)复制口令文件至测试库（172.17.4.61）。
[[email?protected] dbs]$ pwd /u01/app/product/11.2.0/db_1/dbs [[email?protected] dbs]$ scp 172.17.4.60:/u01/app/product/11.2.0/db_1/dbs/orapworadb ./ [[email?protected] dbs]$ ls -lht 总用量 20K -rw-r-----. 1 oracle oinstall 1.5K 12月 29 15:48 orapworadb -rw-r--r--. 1 oracle oinstall 19 12月 29 15:44 dummy.ora -rw-rw----. 1 oracle oinstall 1.6K 12月 29 15:27 hc_oradb.dat -rw-r-----. 1 oracle oinstall 24 5月 15 2017 lkORADB -rw-r--r--. 1 oracle oinstall 2.8K 5月 15 2009 init.ora
Step 4.创建相应目录
- 4.1 审计目录
源数据库端(172.17.4.60):
[email?protected]> show parameter audit_file_dest NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ audit_file_dest string /u01/app/admin/oradb/adump
测试数据库端(172.17.4.61):
[[email?protected] oradb]$ mkdir -p /u01/app/admin/oradb/adump
- 4.2 快速恢复区目录
源数据库端(172.17.4.60):
[email?protected]> show parameter db_recovery_file_dest NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /u01/app/fast_recovery_area db_recovery_file_dest_size big integer 4182M
测试数据库端(172.17.4.61):
[[email?protected] oradb]$ mkdir -p /u01/app/fast_recovery_area
- 4.3 数据目录
源数据库端(172.17.4.60):
[email?protected]> select name from v$dbfile; NAME -------------------------------------------------------------------------------- /u01/app/oradata/oradb/users01.dbf /u01/app/oradata/oradb/undotbs01.dbf /u01/app/oradata/oradb/sysaux01.dbf /u01/app/oradata/oradb/system01.dbf
测试数据库端(172.17.4.61):
[[email?protected] oradb]$ mkdir -p /u01/app/oradata/oradb/ [[email?protected] oradb]$ ls -ld /u01/app/oradata/oradb/ drwxr-x---. 2 oracle oinstall 4096 12月 29 15:27 /u01/app/oradata/oradb/
Step 5.net服务
测试数据库端(172.17.4.61):
[[email?protected] ~]$ cat /u01/app/product/11.2.0/db_1/network/admin/listener.ora
