Cloning

简介：

10g以后 oracle支持cloning，克隆是复制现有的安装到不同的服务器或位置的过程，克隆类似于OUI “克隆模式”操作，会复制Oracle home的所有文件到目标端。

源服务器和目标服务器应具有相同的配置和程序包安装。

克隆不能跨平台。

克隆可以用OPatch或者OUI来删除patch。

用处：

1. 创建一个具有很多patch的环境。

2. 创建一个开发或测试环境。

3. 创建Oracle home在多个主机。

4. 快速部署an instance and the applications。

方式：

1.Clone using “perl clone.pl”In this method you need to install DB Console so that the required Perl files will be installed in $ORACLE_HOME/clone/bin.

2.Clone using “runInstaller”In this method you need to install DB Console

3.Clone using “runInstaller in silent” modeIn this method you will be using same “runInstaller” in non-interactive mode

步骤：

1. 源端复制Oracle installation到目标端。

2. 运行OUI。

Step 1: Copy source Oracle Installation

在做copy之前，关闭数据库，监听，代理，etc，只复制HOME的话，不用管实例。

根据目录以及实例名的不同，排除敏感目录以及文件

Database related directories

o $ORACLE_HOME/dbs ( init.ora,spfile.ora,orapwd)

o $ORACLE_HOME/admin (trace, alert, core files…etc)

o $ORACLE_BASE/diag (trace, alert, core, incident files…etc)

o $ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole__ (Enterprise manager/db console)

o $ORACLE_HOME/hs/admin/ (heterogeneous files)

$ cat exclude_list.txt
./network/admin/listener.ora
./network/admin/sqlnet.ora
./network/admin/tnsnames.ora
./bin/nmo
./bin/nmb

./bin/nmhs

源端解压：

$ cd $ORACLE_HOME
$ tar -zcvf ~/Oracle_Home11g_clone.tar.gz . -X ~/exclude_list.txt > ~/ Oracle_Home11g_clone.log

目标端要满足oracle的要求，用户，目录，权限等。

传到目标端后，进行解压

$ cd $ORACLE_HOME
$ tar -xvf Oracle_Home11g_clone.tar.gz

Step 2: Clone Oracle Installation

确保目标端ORACLE_HOME和ORACLE_BASE环境变量设置，/etc/orainst.loc (for AIX,Linux), /var/opt/oracle/oraInst.loc (for Solaris,HP-UX)文件已经存在。

例子：

$ cat /etc/oraInst.loc
inventory_loc=/home/oracle/oraInventory
inst_group=dba

如果orainst.loc文件存在于不同的位置，可以创建一个软链接或编辑$ORACLE_HOME/clone/config/cs.properties file，并添加“–invPtrLoc /oraInst.loc”参数到”clone_command_line”.

If you have copied oracle Inventory, then you will receive a message that the inventory already exists when you run “clone.pl” or “./runInstaller” to clone the Oracle installation. So before you run cloning commands makes sure to detach the Oracle home.

See below See the below example to detach the oracle inventory:

$ cd /home/oracle/product/11.2.0/dbhome_1/oui/bin
$./runInstaller -detachHome ORACLE_HOME=/home/oracle/product/10.2.0/db_1
Starting Oracle Universal Installer...

No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /home/oracle/oraInventory
‘DetachHome’ was successful.

1. Clone using “perl clone.pl”

$ cd $ORACLE_HOME/clone/bin
$ perl clone.pl ORACLE_HOME="" ORACLE_HOME_NAME=""

Where
ORACLE_HOME: specifies the new Oracle home directory location
ORACLE_HOME_NAME: specifies a unique name for the Oracle Home for the server

See the below example to clone the installation using “perl clone.pl”.

$ perl clone.pl ORACLE_HOME="/home/oracle/product/11.2.0.4/dbhome_1"

2. Clone using “runInstaller”

$ORACLE_HOME/oui/bin/runInstaller -clone ORACLE_HOME=""
ORACLE_HOME_NAME=""

Where
-clone: specifies that the home is a clone of another location
ORACLE_BASE: specifies the base directory location for Oracle products
ORACLE_HOME: specifies the new Oracle home directory location
ORACLE_HOME_NAME: specifies a unique name for the Oracle Home for the server

See the below example to clone the installation using “runInstaller”.

To complete the clone you should log in as “root” and run $ORACLE_HOME/root.sh.

# /home/oracle/product/11.2.0.4/dbhome_1/root.sh
