ORA-12547: TNS:lost contact
<p>I downloaded a docker container with oraclexe 11g on Ubuntu 14.
Everything worked as expected, i created tables, insert data, etc and then i commit the container, generating a new image(same oracle image, but with my tables and data).</p>

<p>Problem:</p>

<p>I can´t connect to my database in my newly created image, either local or remote.
Any tips on that error?
Oracle image:
<a href="https://hub.docker.com/r/sath89/oracle-xe-11g/" rel="nofollow">https://hub.docker.com/r/sath89/oracle-xe-11g/</a></p>
