Oracle lsnrctl: error while loading shared libraries: /u01/app/oracle/product/11.2 Solution

last updated June 24, 2010 in Linux

I‘m using RHEL and whenever I type the command lsnrctl; I get the following error:

lsnrctl: error while loading shared libraries: /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1:
cannot restore segment prot after reloc: Permission denied

How do I fix this problem?

This problem is related to SELinux and can be fixed by turning off SELinux totally as follows:
system-config-securitylevel
Make sure you disable SELinux. Save and close the application. Reboot the server:
reboot

I have a small favor to ask. More people are reading the nixCraft. Many of you block advertising which is your right, and advertising revenues are not sufficient to cover my operating costs. So you can see why I need to ask for your help. The nixCraft takes a lot of my time and hard work to produce.
