Issue/Introduction

Trying to start the IDMS Storage Pool Interval Monitor with command:

SMON INIT THR 70 INT 120

It fails with error:

Free Storage Monitor function invalid

In the CV log the following messages are seen:

DC015014 Vnn Tnnnn Free Storage Monitor not active
DC015017 Vnn Tnnnn Free Storage Monitor function invalid

Environment

Release : 19.0

Cause

The Storage Pool Interval Monitor was introduced by PTF SO15100.
There are two tasks SMON and *STGMON*  and a number of programs that need to be defined to the SYSGEN for this feature to work correctly.      
These are documented in the HOLDDATA for SO15100.

Resolution

 In this case task *STGMON* was missing from the sysgen.

The HOLDDATA for SO15100 explains how define this task and all other tasks and programs required.
