Issue/Introduction:

If you have a secondary Hub configured with the probe HA for a fail over purpose and after the primary hub fail and the HA hub got up and running and the probe data engine don't get the port and pid, check the log to see if you have a issue with the database connection:

Cause:

The probe data engine parameters is configured with Integrated Security=SSPI

parameters = Network Library=dbmssocn;Language=us_english;Integrated Security=SSPI

This parameters is the same as Integrated Security=true;

This parameters force the secondary hub to connect to the Database as windows user authentication.

Environment:

Secondary Hub with probe HA configured with Microsoft SQL server

Resolution:

Remove the Integrated Security=SSPI from the parameters on the data_engine.cfg on the HA hub.

change this line:

parameters = Network Library=dbmssocn;Language=us_english;Integrated Security=SSPI

to

parameters = Network Library=dbmssocn;Language=us_english

Restart the data_engine probe.
