ORA-12547: TNS:lost contact

Question

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).

Problem:

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

Answer 1

The problem is with the dockerfile mounting the oracle data folder VOLUME "/u01/app/oracle"

When i commit my container, this folder is not saved into my new image, generating the errors to start the db.
