Halt or Complete Running Jobs

Tenable recommends stopping all running Tenable Security Center processes before beginning an upgrade. If processes are running (for example, Tenable Nessus scans), Tenable Security Center displays the following message along with the related process names and their PIDs:

SecurityCenter has determined that the following jobs are still running. Please wait a few minutes before performing the upgrade again. This will allow the running jobs to complete their tasks.

Stop the processes manually or retry the upgrade after the processes complete.

To stop processes running on Tenable Security Center:

1. Log in to Tenable Security Center via the command line interface (CLI).

2. Stop Tenable Security Center with the following command:

   Copy

   # /bin/systemctl stop SecurityCenter

   Tenable Security Center stops.

3. In the CLI in Tenable Security Center, run the following command to view all running processes:

   Copy

   # ps -fu tns

4. If any processes are listed, run the following commands to stop them:

   Copy

   # killall -u tns

   Copy

   # killall httpd

5. If necessary, repeat step 4 to confirm all processes stopped.

Perform a Tenable Security Center Backup

Perform a backup of Tenable Security Center before beginning your upgrade. For more information, see Backup and Restore.
