Message BACK END SYSTEM IS NOT ACTIVE in UCFTSO clist

Products

• IDMS
• IDMS - Database

Issue/Introduction

After upgrading IDMS and completing all configuration jobs, CV comes up successfully, but attempts to access the CV via a UCFTSO clist gives only BACK END SYSTEM IS NOT ACTIVE with no other error messages or abend codes.  

Typically UCF returns abend code such as S019 or other Snnn error.

Environment

Release: All supported releases.
Component: UCF.

Cause

In this case it was determined that the client had not properly generated their SYSTEM to include a UCF LINE and the associated PTERM/LTERM definitions.

Resolution

To access an IDMS CV via any UCF connection (UCFCICS, UCFTSO or UCFBATCH), the IDMS SYSTEM definition must include an ENABLED UCF LINE definition and several sets of PTERM/LTERM definitions for as many concurrent user connections as will be required.
