What are the two different types of coupling facility rebuilds available to recover from a TPX CF failure?

Products

• TPX - Session Management

Issue/Introduction

 Coupling facility (CF) failures require a TPX reconnect using REBUILD function.

 

 

Resolution

If the Coupling Facility (CF) feature is in use with Generic Resources and a CF failure occurs then managed rebuilds are required based upon what kind of CF failure is observed:

• System managed rebuild is a "controlled" situation where a command is issued from the console to start the rebuild and then stop the rebuild.
  
  
• User managed rebuild or Application managed rebuild (both names get used) deals with recovering from a CF structure disconnect.
