Oracle11g libnnz11.so: cannot restore segment prot after reloc: Permission denied

[oracle@oracle11g ~]$ lsnrctl status lsnrctl: 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
Operating System: Virtual Machine: Oracle Enterprise Linux 5.2 (32-bit)
Oracle RDBMS Version: Oracle 11g - 32 bit for Linux

This is the error due to SE Linux running in Enforce mode. The best way to avoid this is – make the SE Linux in Permissive mode. This can be done at the time of Setting up your server (by not selecting the security feature) (or) once the server setup completes you can set the value to 0.
