Ask Data Process Failed To Start Up After Making Some Topology Change

Issue

Ask Data process failed to start up after some topology change is made, for example adding a new node on Tableau Server

Environment

Tableau Server

Resolution

Use [netsh interface ipv6 show prefixpolicies] command to check the current precedence of multiple IP addresses, and use [netsh int ipv6 set prefixpolicy] command to modify the precedence.

Below is an example where IPv6 is preferred over IPv4.
Precedence Label Prefix
---------- ----- --------------------------------
50 0 ::1/128
40 1 ::/0
35 4 ::ffff:0:0/96
30 2 2002::/16
5 5 2001::/32
3 13 fc00::/7
1 11 fec0::/10
1 12 3ffe::/16
1 3 ::/96

To change the precedence to make sure IPv4 is preferred, you need to execute the following steps:
a) Run [tsm stop] command to stop Tableau Server.
b) Run the following commands to adjust precedences of IP addresses.
  netsh int ipv6 set prefixpolicy ::ffff:0:0/96 50 0
  netsh int ipv6 set prefixpolicy ::1/128 40 1
  netsh int ipv6 set prefixpolicy ::/0 30 2
  netsh int ipv6 set prefixpolicy 2002::/16 20 3
  netsh int ipv6 set prefixpolicy 2001::/32 5 5
  netsh int ipv6 set prefixpolicy ::/96 1 4
c) Reboot OS to restart Tableau Server administrative services.
d) Run [tsm start] command to start up Tableau Server.
