Unknown Server Error on Tableau server reports

Troubleshooting


Problem

When I tried to open reports on Tableau server, I got a pop-up saying "Unknown Server Error" for all the reports

Cause

Unknown Server Error can be caused by various reasons. One of them is that PA Vertica database or the Vertica server that Tableau server connects to is down

Diagnosing The Problem

1. Log on to one of Vertica server as dbadmin

2. Launch Vertica adminTools utility by running "/opt/vertica/bin/adminTools" command

3. Check whether the database or any of hosts is down by selecting "View Database Cluster State"

Resolving The Problem

If the database or any of Vertica hosts is down, bring it up with adminTools utility:

- If database is down, select "Start Database"

- If one of database hosts is down, select "Restart Vertica on Host"
