Oracle 10g,11g中的数据库克隆安装

有时候在很多工作环境中,如果彼此几个机器的配置相似,我们就可以不用一遍又一遍的安装数据库软件了,我们可以为了更快的完成安装工作,在静默安装,图形安装的选择之外,还有克隆安装。不过在Oracle 10g,11g的版本中还是存在一定的差别。虽然方法有差别,但是思路都是一致的。

我们可以从源环境中直接把ORACLE_HOME给打个包,在目标环境解压即可。这个时候尽管你去尝试sqlplus,exp这些工具也能用,但是还是存在很大的风险,毕竟别把它当成绿色版的。出了问题谁都兜不住。

11g的环境中,可以使用下面的方式来安装。

到达$ORACLE_HOME/clone目录下,运行下面的脚本即可。输入的参数为ORACLE_HOME,还有ORACLE_HOME的名字,这个可以自己定义。

$ perl clone.pl ORACLE_BASE=/U01/app/oracle ORACLE_HOME=/U01/app/oracle/product/11.2.0.2/db_1  ORACLE_HOME_NAME=OraDb10g_home1
 ./runInstaller -clone -waitForCompletion  "ORACLE_BASE=/U01/app/oracle" "ORACLE_HOME=/U01/app/oracle/product/11.2.0.2/db_1" "ORACLE_HOME_NAME=OraDb10g_home1" -silent -noConfig -nowait

然后根据提示使用root运行两个脚本即可。
10g的数据库软件就得换个方式,
 $ORACLE_HOME/oui/bin/runInstaller -clone -silent -ignorePreReq ORACLE_HOME="$ORACLE_HOME" ORACLE_HOME_NAME="OraDb10g_home1"

然后根据提示运行一个脚本。

如果拿11g的ORACLE_HOME采用10g的思路,报出的错误都让人摸不着头脑,因为ORACLE_BASE早就指定了。
 $ORACLE_HOME/oui/bin/runInstaller -clone -silent -ignorePreReq ORACLE_HOME="$ORACLE_HOME" ORACLE_HOME_NAME="OraDb10g_home1"

不过对于这种克隆方式还是需要简单验证一下,如果出现了意料之外的问题就是弄巧成拙了。
