DBA组下不同成员登录ORACLE的情况

DBA组下不同成员登录ORACLE的情况，报错的问题。
将admin 用户加入oracle 用户组。
root@r01c05011.yh.com # usermod -g oinstall admin
root@r01c05011.yh.com # usermod -g dba admin    
root@r01c05011.yh.com # su - admin
admin@r01c05011.yh.com:/home/admin>sqlplus /nolog       
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
查询metalink发现是ORACLE 10g R2的一个BUG，版本号为4516865。下载补丁，并解压。

将install目录下的changePerm.sh和restrict.lst这两个文件解压到$ORACLE_HOME/install文件夹下。
