Oracle Study之--通过RMAN克隆测试库
Oracle Study之--通过RMAN克隆测试库
通过使用数据库备份，DBA可以在同一服务器或其它服务器上建立副本数据库。这个副本数据库可以和主数据库有相同的名称（拷贝）或与主数据库名称不同（克隆）。ORACLE在数据库拷贝和数据库克隆之间惟一不同的是拷贝的数据库不能更改名称。使用RMAN的复制数据库特性，可以从RMAN备份创建一个新的数据库，并为这个副本数据库保留已有的数据库名称或者赋予新的名称。
RMAN术语和命令：
A．辅助数据库(Auxiliary database)：RMAN将目标数据库复制到该数据库实例。要创建该数据库的参数文件、路径和口令文件。必须在RMAN数据库复制之前以非加载(NOMOUNT)模式启动辅助数据库实例。
B．复制(Duplicate)：从其它数据库的RMAN备份创建一个新的数据库。要在RMAN执行复制的位置配置数据库并启动Oracle的实例。从RMAN的角度来看，目标数据库被复制到副本数据库。
C．设置新名称(Set newname)：在一个RMAN运行块内为数据文件设置新的名称，提供给该参数的文件名称覆盖任何该数据文件的辅助数据库名(用SET AUXNAME)或者辅助数据库参数(DB_FILE_NAME_CONVERT)。这个新名称的值只在运行块内有效。
D．设置辅助名称(Set auxname)：为数据文件设置辅助名称，这个辅助名称将在RMAN会话之间存在。如果不希望以后的RMAN命令中使用这个设置的名称，则必须将该名称设置为NULL。
E．日志文件(log file)：可以在Duplicate命令中作用这个关键词，以指定副本数据库创建的联机重做日志文件。如果没有特别指定这个关键词，则RMAN将在辅助参数文件中的LOG_FILE_NAME_CONVERT参数决定的路径中生成日志文件。如果没有这个RMAN关键词，而且也没有设置辅助参数，则RMAN将在目标数据库同样的位置创建日志(假设已指定了NOCHECKFILENAME选项)。
F．不检查文件名(Nocheckfilename)：默认情况下，RMAN将检查在副本主机上被恢复到主目标数据文件路径下的数据文件，以确保不会被错误地覆盖。使用该选项可以覆盖这个默认的操作。这样就需要手工确保RMAN没有覆盖任何已存在的数据文件。应当谨慎使用这个命令，以防止覆盖数据文件。
在Duplicate命令执行的过程中，RMAN执行了一系列工作。当连接到目标、辅助和或选的目录数据库后，RMAN将进行以下操作：
1) 根据最近发生的或者是提供的恢复停止点来决定复制操作将使用哪个基本的备份。
2) 根据辅助数据库参数或RMAN设置的命令和选项来决定将数据文件保存在辅助数据库实例的什么位置。
3) 为辅助数据库读出备份片或映像拷贝并恢复数据文件。这个RMAN的功能与执行正常的数据库还原是一样的。
4) 根据恢复停止点将任何增量备份应用于还原数据文件。这个增量方式的应用与用RMAN发布恢复数据库命令的任务是一样的。
5) 根据恢复停止点从磁盘或备份将所有归档日志文件应用于还原数据文件。
6) 为辅助数据库创建新的控制文件。
7) 当重新设置联机重做日志文件时，打开副本数据库。新的联机重做日志文件将根据RMAN复制数据库命令中指定的或者根据转换的辅助参数文件进行创建。
系统环境：
环境： RedHat 4 + Oracle 10g
主库库名： db01
克隆库名： clonedb
1、主库db01 ，用rman进行备份（datafile、controlfile、archivelog file）
08:49:43 SQL> show parameter name ;
NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_file_name_convert string db_name string cuug db_unique_name string cuug global_names boolean FALSE instance_name string cuug lock_name_space string log_file_name_convert string service_names string cuug
08:49:53 SQL> select current_scn from v$database;
CURRENT_SCN
-----------
1139339
对数据库进行备份：
RMAN> run {
2> allocate channel c1 type disk;
3> allocate channel c2 type disk;
4> backup full database format '/disk2/rman/db01/hot_bak/%d_%s_%t.bak';
5> backup archivelog all format '/disk2/rman/db01/hot_bak/arch_%s.bak';
6> backup current controlfile format '/disk2/rman/db01/hot_bak/ctl_%s.bak';
7> }
08:58:59 SQL> col file_namr for a50
08:59:19 SQL> select file_id,file_name,tablespace_name from dba_data_files; FILE_ID FILE_NAME TABLESPACE_NAME ---------- -------------------------------------------------- ------------------------------ 5 /u01/app/oracle/oradata/db01/lxtb1.dbf LXTBS1 4 /u01/app/oracle/oradata/db01/users01.dbf USERS 3 /u01/app/oracle/oradata/db01/sysaux01.dbf SYSAUX 2 /u01/app/oracle/oradata/db01/rtbs01.dbf RTBS 1 /u01/app/oracle/oradata/db01/system01.dbf SYSTEM 8 /u01/app/oracle/oradata/db01/undotbs1.dbf UNDOTBS1 11 /u01/app/oracle/oradata/db01/tbsbig.dbf TBS_BIG 12 /u01/app/oracle/oradata/db01/indx01.dbf INDX 6 /u01/app/oracle/oradata/db01/lxtbs2.dbf LXTBS2
2、建立pfile 文件
08:59:31 SQL> create pfile from spfile;
File created.
3、建立克隆库的目录
[oracle@RH4 dbs]$ mkdir -p $ORACLE_BASE/admin/clonedb/bdump [oracle@RH4 dbs]$ mkdir -p $ORACLE_BASE/admin/clonedb/cdump [oracle@RH4 dbs]$ mkdir -p $ORACLE_BASE/admin/clonedb/udump [oracle@RH4 dbs]$ mkdir -p $ORACLE_BASE/oradata/clonedb
4、将主库pfile 拷贝生成clone 库的pfile，并生成clone库的口令文件
[oracle@RH4 dbs]$ orapwd file=orapwclonedb.ora password=oracle entries=3;
[oracle@RH4 dbs]$ cp initdb01.ora initclonedb.ora
[oracle@RH4 dbs]$ vi initclonedb.ora
将db01 替换为 clonedb，并增加以下内容：
db_file_name_convert = ("/u01/app/oracle/oradata/db01" ,"/u01/app/oracle/oradata/clonedb")log_file_name_convert = ("/disk1/oradata/db01","/disk1/oradata/clonedb","/disk2/oradata/db01","/disk2/oradata/clonedb")
5、将clone 库启动到nomount
[oracle@RH4 dbs]$ export ORACLE_SID=clonedb [oracle@RH4 dbs]$ sqlsqlplus '/as sysdba' SQL*Plus: Release 10.2.0.1.0 - Production on Fri Mar 23 09:11:22 2012 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to an idle instance. 09:11:22 SQL> startup pfile=$ORACLE_HOME/dbs/initclonedb.ora nomount ORACLE instance started.

6、对主库的日志进行归档，并将归档日志拷贝到clone库的归档目录下
09:23:47 SQL> select * from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIME---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- ------------------- 1 1 14 10485760 2 YES INACTIVE 1134075 2012-03-23 05:23:36 2 1 15 10485760 2 NO CURRENT 1141263 2012-03-23 08:57:57 3 1 12 10485760 2 YES INACTIVE 1123738 2012-03-23 02:54:16 4 1 13 10485760 2 YES INACTIVE 1126370 2012-03-23 03:23:17 09:55:18 SQL> alter system archive log current; System altered. 09:57:35 SQL> select * from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIME---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- ------------------- 1 1 14 10485760 2 YES INACTIVE 1134075 2012-03-23 05:23:36 2 1 15 10485760 2 YES ACTIVE 1141263 2012-03-23 08:57:57 3 1 16 10485760 2 NO CURRENT 1143553 2012-03-23 09:57:35 4 1 13 10485760 2 YES INACTIVE 1126370 2012-03-23 03:23:17
7、建立clone库的归档目录，并将主库的归档日志拷贝到clone 库下
[oracle@RH4 dbs]$ mkdir /disk1/arch/clonedb [oracle@RH4 dbs]$ cd /disk1/arch/db01/ [oracle@RH4 db01]$ ls arch_1_10_778577586.log arch_1_13_778577586.log arch_1_5_778577586.log arch_1_8_778577586.log arch_1_11_778577586.log arch_1_14_778577586.log arch_1_6_778577586.log arch_1_9_778577586.log arch_1_12_778577586.log arch_1_15_778577586.log arch_1_7_778577586.log [oracle@RH4 db01]$ cp *.* ../clonedb/
[oracle@RH4 db01]$
8、用rman连接主库和clone库
[oracle@RH4 admin]$ export ORACLE_SID=clonedb [oracle@RH4 admin]$ rman target sys/oracle@db01 auxiliary sys/oracle Recovery Manager: Release 10.2.0.1.0 - Production on Fri Mar 23 10:03:55 2012 Copyright (c) 1982, 2005, Oracle.
