Issue/Introduction

We recently installed OPS/MVS web services in our LAB systems and our team is trying to use it but facing issues accessing it.
Symptoms when trying to use the OPS/MVS web services sample application:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
  <WSResult xsi:schemaLocation="http://www.ca.com/automation/opsmvs/websvc/msgData" xmlns="http://www.ca.com/automation/opsmvs/websvc/msgData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">    
    <HttpStatus>404</HttpStatus>
    <HttpReason>Not Found</HttpReason>
    <AppInfo>        
      <Reason></Reason>
         </AppInfo>
   </WSResult>

Environment

Release : 14.0

Cause

One of the possible causes is that the OPS subsystem is not properly setup in the opwebsvc.env file:

export OPS_SUBSYS=YSYS

Resolution

Updating this variable to the correct OPS subsystem solved this problem:

export OPS_SUBSYS=OPSS  

This same symptom can have other causes.
