仔细查看错误提示和安装日志，一般都能定位到问题上，比如配置文件错误，依赖包问题或其他先决条件不满足等，都可以在安装日志中查到。
未安装完成中止的日志在/tmp/OraInstallXXXXX/下，其中XXXX为安装日期，
故障1
[oracle@L134 ~]$ sqlplus
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory 原因：环境变量未配置或配置有问题
[oracle@L134 ~]$ echo $ORACLE_HOME
/data/oracle/11g2a发现ORACLE_HOME的路径写错，改正后再source一次即可。
故障2
重新安装oracle时，没有orainstRoot.sh文件
只提示运行：/data/oracle/product/10.2.0/crs_1/root.sh这个文件。
原因：没删除/etc/oraInst.loc文件
故障3
静默安装Oracle时提示："[SEVERE] - Email Address Not Specified"
系统环境：CentOS 6.3 x86_64 + Oracle 11gR2
解决办法：
修改responseFile文件，将DECLINE_SECURITY_UPDATES=的值设为true，如果为空系统会假设该值为false，DECLINE_SECURITY_UPDATES=的值默认为空。

故障5
[FATAL] [INS-13013] Target environment do not meet some mandatory requirements.
CAUSE: Some of the mandatory prerequisites are not met.
解决办法：
详细查看安装日志。搜索SEVERE，FAILED，Severity，CRITICAL，Error这几个关键字，看为什么没有通过校验。
如果实丰没有办法，如在CentOS 6.x 64位下，已经安装了glibc-2.12-1.209.el6_9.2.x86_64，但在检验时，出现如下错误。因为oracel要求:glibc-2.3.4-2.41(i686) 32位的，但实际已经安装64位更新的版本了，此检验可以忽略。找到32位的旧版本的glibc，但死活安装不上。最后只能加上-ignorePrereq参数，但最好还是全部通过检验比较好。
