Restart all services

Introduction

The out-of-the box stop and start script is silent and generates no screen output . It is non-system specific i.e. services will fail to stop and/or start and the user cannot  know for sure if that behavior is sign of a problem or not.

 

Solution

Running the script

If the system has been installed by COMCERT, we installed a system specific script to restart all services.

In case of an eminent problem, running the restart script may reveal what service failed to start. Mention this service when you contact techsupport.

• You don't have to be root to run this script
• Log in with SSH
• Change to the /opt/tv folder

$ cd /opt/tv

• Run the restart script

$ ./tv-restart-services.sh

Sample screen output on TVC

[TVadmin@crt-vir-a-tvc11 ~]$ cd /opt/tv
[TVadmin@crt-vir-a-tvc11 tv]$ ./tv-restart-services.sh
