[oracle@linux5 bin]$ sqlplus /nolog
sqlplus: error while loading shared libraries: /u01/oracle/lib/libnnz11.so: cannot restore segment prot after reloc: Permission denied
Linux下执行程序时发生错误: cannot restore segment prot after reloc: Permission denied
原来这是SELinux搞的鬼，解决办法有两个
1. 使用chcon 命令
示例: chcon -t texrel_shlib_t /usr/local/rsi/idl_6.1/bin/bin.linux.x86/*.so
2. 禁止掉SELinux
更改/etc/sysconfig/selinux 文件的内容为 SELINUX=disabled
