11gr1,使用OUI进行预安装必要条件检查，避免出现安装过程中的错误

版本：11gr1 - 11.1.0.6

在通过OUI(Oracle Universal Installer)进行安装之前，或者说以Silent方式进行安装之前，已经进行了操作系统方面的配置，如果要保证在通过OUI进行安装的过程中，不中断，不出现问题，要对这些配置进行检查，看配置是否正确，及时修正，才能确保安装过程中，不进行反复的修改。

简单来说，就是安装Oracle需要的必要条件的检查。

 

1.       解压软件包linux.x64_11gR1_database_1013.zip，最终形成的目录如下

 

[oracle@11gdb ~]$ ls

database linux.x64_11gR1_database_1013.zip

 

2.       进入database目录中

 

[oracle@11gdb ~]$ cd database/

[oracle@11gdb database]$ ls

doc  install  README response  runInstaller  stage welcome.html

 

3.       执行如下命令，进行预安装环境检查

 

./runInstaller-prereqchecker PREREQ_CONFIG_LOCATION=./stage/prereq -entryPointoracle.server_EE -prereqLogLoc /tmp -silent

 

执行输出：

 

[oracle@11gdb database]$ ./runInstaller-prereqchecker PREREQ_CONFIG_LOCATION=./stage/prereq -entryPoint oracle.server_EE-prereqLogLoc /tmp -silent

注：

 

l   PREREQ_CONFIG_LOCATION说明配置文件的位置(不同产品类型可能预检查配置文件的目录不同，如ASM，Cluster，Client等不同的产品)

l   -entryPoint 指的是，产品类型，根据不同的产品类型，最终的进入点标识，会有区别

l  -prereqLogLoc 最终生成的日志，比如，错误日志，输出日志的位置

 

注意：

关于ORACLE_HOME,ORACLE_BASE等环境变量的问题，可以忽略，不影响实际的安装，也就是说Check complete: Not executed<<<<即Not executed的可以忽略，但是对于Failed的要给予关注，进行修正，满足最小的安装要求。
