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

in Linux last updated June 24, 2010

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.
