DX UIM Operator Console (OC) Dynamic groups stop updating automatically

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

Dynamic groups stop updating. If I go into edit and press the find and save, it does not update the list.

To work around the problem, I have to make a change to the filter and then change it back to update the list succesfully.

What is causing this issue? 

Environment

DX UIM 20.4.* / 23.4.* 

Cause

When dynamic groups are first created, the wasp probe sends the query to the database. After the creation, the nis_server probe is responsible of updating the dynamic groups.

If the groups are not updating automatically, there might be an issue with the nis_server probe. The nis_server probe is hosted in the primary hub. 

When changing the filter manually, the list updates correctly, because it bypasses the nis_server. 

Resolution

1. First, make sure the correct version of nis_server is installed for your version of DX UIM.

Example: 

Running DX UIM 23.4.2 (CU2), the version of nis_server must be 23.4.2

2. Perform the following steps: 

    •  Deactivate nis_server
    •  Wait for port and pid to clear.
    •  Activate nis_server
