Lsnrctl : error loading shared libraries libnnzll.so

The main problem causing this error is that the SElinux on Rhel 5 is blocking the listener to start the Listener control services ( lsnrctl ) . I had encountered this problem when i was starting the database for Oracle E-Business suite applications.After doin a small research i could get  the solution to this particular problem.

Error : lsnrctl : error loading shared libraries : /directories/libnnzll.so : cannot restore segment prot after reloc : permission denied

Cause : The SElinux of redhat preventing the lsnrctl service to start

Solution : set the SElinux to Permissive and then start the lsnrctl service , this will solve the issue.

Steps : at Root , use the following commands

• getenforce 
• setenforce 0 
• getenforce 

Follow the above commands in sequence at once ,these commands change the SElinux mode to permissive . Hope this will solve the issue .
