Carbon Black App Control (formerly Cb Protection)Carbon Black App Control
Issue/Introduction
The steps are needed to fix an issue when a prioritized agent upgrade fails multiple times due to some reason, and this causes all other agent upgrade requests to stall.
Environment
App Control Server: All Supported Versions
Resolution
Take a full backup of the DAS database. As this requires running a script against the database, having a good backup is highly recommended
Navigate in the console to Administration > System Configuration > Advanced Options
At the bottom of the page, click the "Edit" button
Find the "Allow Agent Upgrades" > Set it to Disabled
At the bottom of the page, click the "Update" button
Temporarily stop the App Control Server and Reporter services
Download the attached "remove_prioritization_upgrade.sql"
Open SQL Mgmt Studio with the service account and Run the "remove_prioritization_upgrade.sql" script
Start the App Control Server and Reporter services
Additional Information
The script will remove any prioritized agent upgrades and then expire the host (forcing the agent to disconnect and then reconnect with the server).
