Issue/Introduction

When trying to start the Agile Central service in the control panel, the following error is seen numerous times in the log:

SQL*Plus: Release 10.2.0.4.0 - Production on Tue Jul 31 08:45:00 2018 Copyright (c) 1982, 2007, Oracle. All Rights Reserved. ERROR: ORA-12541: TNS:no listener Enter user-name: SP2-0306: Invalid option.

Logging into an ssh session and trying to start the Oracle service manually gives the following error:

2. Log in as root
3. Edit the /etc/hosts file
4. Locate the line that begins with 127.0.0.1
5. At the end of that line, add rallyonprem-oraclese.f4tech.com
6. Save the file
7. Issue the following command to start the Oracle database:
