The connection property set was missing a required property or the property value was unrecognized. Instance not available on server

Last Published: June 9, 2023

Error Message

Attempts to validate an ArcGIS Data Store relational data store fail, and return the following error messages in the ArcGIS Server Administrator Directory logs:

Error:   
The connection property set was missing a required property or the property value was unrecognized. Instance not available on server
Error:   
Failed to create the service.: ERROR: unable to connect to the database: <MachineName>. Reason: Instance not available on server

Cause

Missing or inaccurate information in the ArcGIS Data Store configuration file causes the validation to fail as ArcGIS Enterprise is directed to a different or non-existent data store in the deployment.

Solution or Workaround

Unregister and re-register the data store using the ArcGIS Data Store command utilities to reconfigure the data store. After the configuration is completed, proceed to validate the data store.
