Oracle11gR2--克隆安装数据库软件

1. 删除oracle之前的产品信息

环境是前篇中通过静默方式安装的,这里只删除产品信息,假设ORACLE_HOME目录是从其他地方拷贝过来的

[oracle@localhost ContentsXML]$ pwd
/home/oracle/oraInventory/ContentsXML
[oracle@localhost ContentsXML]$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>
<!-- Copyright (c) 1999, 2013, Oracle and/or its affiliates.

<!-- Do not modify the contents of this file by hand. -->
<INVENTORY>
<VERSION_INFO>
   <SAVED_WITH>11.2.0.4.0</SAVED_WITH>
   <MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
<HOME NAME="OraDb11g_home1" LOC="/home/oracle/app/oracle/product/11.2.0/dbhome_1" TYPE="O" IDX="1"/>
</HOME_LIST>
<COMPOSITEHOME_LIST>
</COMPOSITEHOME_LIST>
</INVENTORY>

#删除LIST里的内容
[oracle@localhost ContentsXML]$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>
<!-- Copyright (c) 1999, 2013, Oracle and/or its affiliates.

<!-- Do not modify the contents of this file by hand. -->
<INVENTORY>
<VERSION_INFO>
   <SAVED_WITH>11.2.0.4.0</SAVED_WITH>
   <MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
</HOME_LIST>
<COMPOSITEHOME_LIST>
</COMPOSITEHOME_LIST>
</INVENTORY>

2. 执行克隆安装命令

[oracle@localhost bin]$ pwd
/home/oracle/app/oracle/product/11.2.0/dbhome_1/clone/bin
[oracle@localhost bin]$ perl clone.pl ORACLE_BASE=$ORACLE_BASE ORACLE_HOME=$ORACLE_HOME  ORACLE_HOME_NAME=OraDb11g_home1
./runInstaller -clone -waitForCompletion  "ORACLE_BASE=/home/oracle/app" "ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1" "ORACLE_HOME_NAME=OraDb11g_home1" -silent -noConfig -nowait

3.总结

可以看到通过克隆的方式时间会快很多,因为文件已经实现copy,只剩下link的工作
