Description of problem:
Launching spacewalk-hostname-rename permanently changes oracle listener  configuration and restarts oracle-xe service right away. The result is that oracle listener listens on localhost instead of 0.0.0.0 ( as was configured by install proccess ).
It's not correct, yet unexpected behavior!

Version-Release number of selected component (if applicable):
spacewalk-utils-1.7.15-1.el6.noarch
spacewalk-utils-1.8.4-1.el6.noarch


Steps to Reproduce:
1. netstat -plnt | grep 1521 ( 0.0.0.0:1521 LISTEN 21730/tnslsnr)
2. spacewalk-hostname-rename <IP>
3. netstat -plnt | grep 1521 ( 127.0.0.1:1521 LISTEN 21735/tnslsnr)
  
Actual results:
unexpected changes in oracle listener configuration

Expected results:
oracle listener configuration intact, there's no reason to change it
