应用程序连接oracle的库时会出现如下错误：
XXXXX：: error while loading shared libraries: /usr/local/oracle/product/10.2.0/lib/libnnz10.so: cannot restore segment prot after reloc: Permission denied
或者：
XXXXX：: error while loading shared libraries: /usr/local/oracle/product/10.2.0/lib/libclntsh.so.10.1: cannot restore segment prot after reloc: Permission denied
等错误。
解决办法是用chcon命令把相应文件的属性改一下即可，如：
chcon -t texrel_shlib_t /usr/local/oracle/product/10.2.0/lib/libnnz10.so
chcon -t texrel_shlib_t /usr/local/oracle/product/10.2.0/lib/libclntsh.so.10.1
