How can I disable SELinux in Red Hat?

Question

I'm having some issues with shared libraries in a Red Hat installation, for example when I try to run sqlplus:

error while loading shared libraries: /u01/app/oracle/product/11.2.0/db/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied  

How can I permanently disable SELinux?

Answer 1

SELINUX=disabled  

Answer 2

another possible solution is to execute as root:

#setup 
  Select "Firewall Configuration" 

There you can configure the Firewall and SELinux
