Introduction

Automated Host Instance task configuration allows you to take an action on BizTalk Host Instances.

At times, host instances abruptly stop due to external factors like host throttle conditions (worker/IO thread utilization or orchestration memory throttling violations). In this situation, the BizTalk Administrator must restart the host instances.

Let's see how to automate the above scenario: BizTalk360 supports the PowerShell notification channel, with this you can call the PowerShell script in case of any threshold violation found in monitoring. Create an alarm to monitor host throttling and enable the PowerShell notification channel, which holds the script to call the host instance automated task api. In case of a throttling violation, the BizTalk360 alarm will call the script that you have added to stop/restart the host instances.

BizTalk360 Automated Host Instances tasks allow you to take the below actions 

  • Start 
  • Stop 
  • Restart
  • Enable 
  • Disable

Host Instance Task Configuration 

  • Navigate to Environment Settings->Automated Task ->New Task Configuration 
  • In The New Task Configuration select Host Instances which will open the task configuration blade  
  • Add the Task Name and Description 
  • Task Type - Host Instance is chosen by default, which you cannot modify 
  • Select Host Instance- Select one or more Host Instances in which you want to take an action 
  • Action- Select which action needs to perform Start/Stop/restart or Enable/Disable the host instance 
  • At least one Active 
    The clustered host instances are listed with color codes. To avoid downtime "At least one Active " can be set by selecting both clustered host instances. When the action is set as "At least one Active" the system will make sure at least one instance is up and running.

  • Enable/Disable the task for execution. By default, the task execution will be enabled
  • Run this task immediately after saving - Enable this option to run the task immediately after saving the task configuration. However, the same task will execute again during the scheduled time.
  • Follow this article for Schedule Configuration 
  • Notification Configuration - Enable the channels in which you wish to get notified about the actions performed on Application Artifacts. 

On successful task configuration, you can see the task in the configuration grid along with the task name, resource type, resource details, action, schedule type, and next execution time.
