10 Manage the Transaction Coordinator

If you have installed Transaction Manager for Microservices (MicroTx) on a Kubernetes cluster using Helm, you can use Helm commands to manage the transaction coordinator.

• About Session Affinity
  When you enable session affinity, all the requests for a unique transaction or session are routed to the same endpoint or replica of the participant service that served the first request.
• Enable Caching
  When you enable caching, it optimizes the read and write operations for the transaction logs that are stored in etcd or Oracle Database. This in turn improves the performance.
• About Transaction Recovery
  The transaction coordinator server resumes the transactions that were in progress when server the restarts after a failure.
• General Syntax of Commands
  The following is the general syntax of the Helm commands that you can run to manage MicroTx.
• Scale up or down
  Scale up the Kubernetes cluster on which you have installed MicroTx to handle a large amount of requests. When the number of requests is low, scale down to use the resources efficiently.
• Update
  
• Uninstall
  When you no longer want to use MicroTx, you can uninstall it from the Kubernetes cluster.
