Issue/Introduction

The SPECTRUM data source in Dx NetOps Portal. shows  a status of busy and it is not syncing elements between Dx NetOps Portal and Spectrum:

Environment

DX NetOps Spectrum & DX NetOps Performance Management all Releases

Cause

The following is seen in the Dx NetOps Portal Data Sources Manager log (DMService.log) all through it:

INFO  | pool-4-thread-22         | 2023-07-03 10:20:11,436 | com.ca.im.portal.dm.productsync.DataSourcePoller                 
      | Data source Spectrum@SPEC_ONECLICK-1 is too busy to perform a sync.

Then looking at the Spectrum OneClick server log, we see the following repeatedly:

Jul 03, 2023 10:20:09.451 (http-nio-80-exec-268) (NetqosSyncLog) - (ERROR) - Sync attempted when one or more SpectroSERVERS are not connected to the OneClick server

This shows that the OneClick server hasn't reset the status of the landscape that was down. 

All primary SpectroSERVERs must be running for the Dx NetOps Portal data source to sync with Spectrum. If any of the Primary SpectroSERVERs are down or failed over to Secondary, the DX NetOps Portal data source will show busy and not sync new items. 

Resolution

Validate that all primary SpectroSERVERs in a distributed SpectroSERVER environment are up and running. Once the servers are up and running, Spectrum should sync successfully with Dx NetOps Portal

If the primary SpectroSERVERs are all up and running and the data source is still showing as busy in Dx NetOps Portal then restart the Spectrum OneClick server. Then re-sync the Spectrum Data Source in Dx NetOps Portal.
