Install the Worker/Listener

Overview

The Worker and Event Listener are vital components for real-time Data syncs. Here's a brief overview of how the Worker/Event Listener operates:

• The Event Listener, once successfully subscribed, awaits events from the streaming source.
• Upon receiving a message from a streaming source, the Event Listener pushes it to the message queue.
• The Worker then retrieves the message from the message queue.
• The Worker fetches the corresponding record from the target based on the sync key.
• If changes are detected, the Worker pushes them to the target system. Both successes and failures get logged in the worker's log file.

caution

For a Kubernetes deployment of the Cinchy Platform, the Worker/Event Listener is automatically installed. The steps below are specific to an IIS deployment of the Cinchy Platform.

Prerequisites

• Windows Server 2012+
  • .NET Core 3.1 Hosting Bundle
• SQL Server 2012+
  • Service Broker enabled
• Cinchy Platform
• 4 x 2 Ghz Processor
• 16-24GB RAM

SQL Service Broker setup

You must set up the Worker Queues and the SQL Service Broker prior to install.

1. Navigate to the Cinchy Releases table and download the create_queues script from the Script Artifacts column. For access, please contact Cinchy Support
2. On a Windows Server machine, launch an instance of PowerShell as the Administrator.
3. Run the below command the enable the Service Broker:

ALTER DATABASE [Your Cinchy Database Name] SET ENABLE_BROKER WITH ROLLBACK IMMEDIATE;

4. To set up the worker queues , make the following changes and run the create_queues script:

-- Change [cinchy] to match your database name
USE [cinchy];

-- Update the below @user, @password, @db, and @schema values to match your configuration
DECLARE @user NVARCHAR(100) = 'cinchytst';
DECLARE @password NVARCHAR(100) = 'test';
DECLARE @db NVARCHAR(100) = 'cinchy';
DECLARE @schema NVARCHAR(100) = 'dbo';
