解决：[INS-20802] Oracle Net Configuration Assistant failed

在linux 中安装Oracle 11G 的时辰呈现

[INS-20802] Oracle Net Configuration Assistant failed

是oracle数据库的鼓掌，须要补丁p8670579_112010_LINUX

解决办法：

1. Oracle帐号操纵，上传补丁到/u01下，解压。（在oracle用户可能没权限转移，用root转移）

[oracle＠dbserver u01]￥ cd 8670579/

[oracle＠dbserver 8670579]￥ ls
etc  files  README.txt
2. 
打补丁要重视下，选择Optch目次一般在ORACLE_HOME 目次下（下面再次切换oracle用户，免得提示不可）

[oracle＠dbserver 8670579]￥ ￥ORACLE_HOME/OPatch/opatch apply 
-invPtrLoc ￥ORACLE_HOME/oraInst.loc
