Troubleshooting
Problem
When patching a App Host that has been detached from the deployment, the installer can hang when 'Applying presql script' in the QRadar command line interface. Administrators who experience this issue can confirm the process ID for the IMQ service and apply the described workaround to continue the upgrade. It is critical that administrators do NOT attempt to reboot or force the installer to quit, but use the IMQ service instructions provided in this technical note to allow the App Host upgrade to continue.
Symptom
If the detached QRadar App Host appliance appears to be stuck on 'Applying presql script' and does not transition to the next step in the patch process after 10 minutes or more, administrators might need to apply the workaround in this technical note.
