Airflow Scheduler Invalid IPV6 Error and Processing Mining Degradation After Install

News Knowledge Base

What to do when the Airflow scheduler fails due to an invalid IPV6 error and Processing Mining is in a degraded state after installation?

Issue Description:

When Process Mining is installed on a nonstandard port, the SQL validation checks during install will pass; however, table creation will not complete and the database is rendered inaccessible by the application.

Resolution:

If the SQL port is running on a nonstandard port (anything other than 1433), follow the below steps:

  1. Uninstall Process Mining, update the cluster_config.json by setting the 'processmining.enabled' parameter to false. Afterward, execute the installer again with the -s parameter.
  2. Change the listening port on the SQL Server to 1433
  3. Update the relevant SQL Connection strings for Process Mining within the cluster_config.json
  4. Recreate the databases using the provided scripts below.


Dropping Existing Databases:

USE master;

DROP TABLE IF EXISTS AutomationSuite_Airflow;
DROP TABLE IF EXISTS AutomationSuite_ProcessMining_Metadata;
DROP TABLE IF EXISTS AutomationSuite_ProcessMining_Warehouse;

GO;

Recreating the Databases:

-- Create AutomationSuite_Airflow database with READ_COMMITTED_SNAPSHOT option

CREATE DATABASE AutomationSuite_Airflow;
GO

ALTER DATABASE AutomationSuite_Airflow SET READ_COMMITTED_SNAPSHOT ON;
GO

-- Create AutomationSuite_ProcessMining_Metadata database
CREATE DATABASE AutomationSuite_ProcessMining_Metadata;
GO

-- Create AutomationSuite_ProcessMining_Warehouse database
CREATE DATABASE AutomationSuite_ProcessMining_Warehouse;
GO

-- Set READ_COMMITTED_SNAPSHOT option for AutomationSuite_ProcessMining_Metadata
ALTER DATABASE AutomationSuite_ProcessMining_Metadata SET READ_COMMITTED_SNAPSHOT ON;
GO
  1. Uninstall Process Mining, update the cluster_config.json by setting the 'processmining.enabled' parameter to true. Afterward, execute the installer again with the -s parameter.
