SELinux Security Issue - Oracle

Issue

• Receiving SELinux errors after installing NetBackup and running the following commands:

  sudo chcon -t textrel_shlib_t /usr/openv/lib/*.so*
  
  for l in /usr/openv/lib/*.so* ; do echo $l:; sudo semanage fcontext -a -t textrel_shlib_t $l; done
  

• We are getting the following errors:

  oracle homedir /opt/oracle or its parent directory conflicts with a defined context in /etc/selinux/targeted/contexts/files/file_contexts,/usr/sbin/genhomedircon will not create a new context. This usually indicates an incorrectly defined system account.  If it is a system account please make sure its login shell is /sbin/nologin.
  

• This is a newly installed Oracle server and needs the home directory to point to /opt/oracle
