[INS-20802] Oracle Net Configuration Assistant failed

[INS-20802] Oracle Net Configuration Assistant failed。在安装Oracle 11g R2时出现了该错误提示。以前安装的时候没有碰到过类似
的错误。原来是64bit和32bit系统兼容性的问题。如果基于64bit硬件安装32bit 的Linux 和32bit的Oracle 11g,则需要安装patch 8670579。下
面给出patch的安装过程。

一、错误提示
    [INS-20802] Oracle Net Configuration Assistant failed .
    Cause --  The plug-in failed in its perform method.
    Action --  Refer to the logs or contact Oracle Support Services.
    Log File Location
      /u01/oraInventory/logs/installActions2011-10-27_02_42-57PM.log 

    查看日志文件：
      
    INFO: Oracle Net Services Configuration:
    INFO: #
    INFO: # An unexpected error has been detected by HotSpot Virtual Machine:
    INFO: #
    INFO: #  SIGSEGV (0xb) at pc=0xa446a43c, pid=9431, tid=3084382264
    INFO: #
    INFO: # Java VM: Java HotSpot(TM) Client VM (1.5.0_17-b02 mixed mode)

    INFO: #
    INFO: # An error report file with more information is saved as hs_err_pid9431.log
    
    运行dbca同时也出现错误
  
二、安装环境
    宿主机：Windows 7(64bit) + Vmware server 2.0.2    
    客户机：Oracle EnterPrise Linux Server release 5.4 (32bit) + Oracle 11g R2(32bit)

三、Oracle 的Bug信息
    从metalink 获得下列bug 信息
    [ID 942076.1]
    X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE [ID 942076.1]
    You are encountering published Bug 8930861, “X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE”
    
    You have Oracle’s 32-bit 11.2.0.1.0 RDBMS software, a supported 32-bit Linux OS, but you are on 64-bit x86_64 hardware.
    
    the command “cat /proc/cpuinfo” shows:
    model name : Quad-Core AMD Opteron(tm) Processor 2356
    
    Solution
    1. Please find out if there is any business reason that the 64-bit hardware is only running a
    32-bit OS. If not, then Oracle recommends that you re-install a 64-bit OS and 64-bit Oracle to
    avoid published Bug 8930861, “X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE”
    
    2. If there is some business reason that you must use 64-bit hardware running a
    32-bit Linux OS, then before you can use the 11gR2 DBCA or NETCA tools, you will need to apply patch 8670579 , “NETCA/DBCA
    FAILED WITH HOTSPOT VIRTUAL MACHINE”. You will be downloading and using file p8670579_112010_LINUX.zip
    
    从上面的描述可知，是将32bit的Oracle 和32bit的Linux 安装到了X86_64的硬件之上，所以出现上述问题，建议安装64bit操作系统和64bit
    Oracle 。可以解决的办法是安装补丁p8670579_112010_LINUX.zip。补丁下载地址：http://download.csdn.net/source/3253906

四、安装补丁
    1、在安装的过程中出现该错误，先不退出安装程序，而是安装补丁文件，再点击安装程序的retry，继续安装即可。
    2、如果在安装数据库的过程中不创建数据库，则不会出现该错误提示，而后续使用dbca或netca会触发同样的错误，因此使用dbca或netca
       前先安装补丁。
    3、安装补丁步骤       

[oracle@orasrv Inst_source]$ cd 8670579/  -->进入到解压路径
[oracle@orasrv 8670579]$ ls               -->README.txt文件中提供了安装方法，可以参照进行安装补丁，注意环境变量的配置
