CentOS 中 Oracle 启动 sqlplus 乱码处理

1. # 常用unicode字符集
export NLS_LANG=american_america.AL32UTF8

 

2. sqlplus: error while loading shared libraries: /u01/app/oracle/product/11.1.0/db_1/lib/libnnz11.so: cannot restore segment prot after reloc: Permission denied

 

解决：
这是因为SELINUX的问题，需要关闭SELINX，执行：/usr/sbin/setenforce 0
引用：

When packaging an application on RHEL or CentOS, you may receive the following error:

cannot restore segment prot after reloc: Permission denied

This is likely due the the SE Linux setting being set to "enforcing"
.
To Temporarily disable enforcement on a running system

/usr/sbin/setenforce 0

To permanently disable enforcement during a system startup
change "enforcing" to "disabled" in ''/etc/selinux/config'' and reboot.
.
By default, CentOS 5 has the SE Linux feature set to "enforcing". We are looking into ways to removing these steps.
