Issue/Introduction

Spectrum OneClick fails to restart on Linux from the OneClick web pages. For example, when changing the web server memory in the "Web Server Memory" page and clicking on the "Save and Reconfigure" button. Or clicking the "Restart OneClick Server" button in the "SSL Certificates" page.
 

Environment

Spectrum OneClick installed on Linux

Cause

When OneClick is restarted from the OneClick web pages, the following command is executed:

at -m -f /app/spectrum/tomcat/webapps/spectrum/restart.sh now 

The problem may be one of the following:

1. at.deny or at.allow is configured on the OS user preventing the user from executing the restart.sh script

2. The atd program is not running

3. A known Linux bug concerning the "at" command. Reference the following:

Bug Description:- https://access.redhat.com/errata/RHBA-2014:1637

Resolution

If the root cause is the at.deny or at.allow is configured on the OS user preventing the user from executing the restart.sh script, modify the at.deny or at.allow to give the user permission to run the restart.sh script. Reference the following:

If the root cause is because the atd program is not running, start atd by running "service atd start" as the root user. Run "chkconfig atd on" as the root user to start atd automatically at system startup.

If the root cause is the known bug concerning the "at" command, install the at-3.1.10-44.el6_6.2.x86_64.rpm patch. reference http://rhn.redhat.com/errata/RHBA-2014-1637.html
