Introduction

IIS Application pool comprises a set of web applications corresponding to one or more worker processes sharing a common configuration, which is responsible for isolating the applications running in the same system and making them to work on their own process.

Though App Pools are designed for always-on usage, you may need to stop or restart them for many factors. Say, If the worker process crashed number of times then App Pool may get stopped,then you need to start it again. Or if the Application pool is experiencing performance or resource issues you may need to restart it. These are day-to-day activities where users should make sure availability of the App Pool, these processes can be automated using the BizTalk360 IIS App Pool Automated Task Feature.

Automated IIS App Pool tasks allow you to automate the below actions 

  • Start 
  • Stop
  • Restart
  • Recycle
