How to reset discovery in CA UIM 8.10 or later 

Environment

Release: CNMSPP99000-8.4-Unified Infrastructure Mgmt-Server Pack-- On Prem
Component:

Cause

What's happening is the wasp probe cannot reach the udm_manager probe on the port that it listens on for Datomic connections(4334). Typically this is a result of a problem in the discovery information.

Resolution

1 deactivate the udm_manager and discovery_server probes

2 At the database run a query to truncate the datomic_kvs table.  

This example is for MS SQL Server using the default database name CA_UIM.

truncate table [CA_UIM].[dbo].[datomic_kvs]

2 activate the udm_manager and discovery_server probes.

Additional Information

If the truncating datomic_kvs does not resolve the problem follow the steps in this knowledge base document.
