Advisory: Significant Performance Issues with ListEncounterRelationships()

May 12, 2020 – Advisory: Significant Performance Issues with ListEncounterRelationships()

InterSystems has corrected a defect affecting performance on both the Edge and Registry resulting in backed up queues and timeouts in processing.

This problem exists for:

  • HealthShare Information Exchange 2018.1
  • HealthShare Unified Care Record 2019.1
  • HealthShare Unified Care Record 2019.2

This defect occurs when a Unified Care Record customer is utilizing the Relationship Registry. The performance issue occurs when the number of relationships becomes very large; the exact number to trigger the problem is unknown but was encountered on a customer system with over 100 million rows in the Relationship Registry table.

If these conditions are present, an inefficient process on the Edge Gateway results in large numbers of transactions being sent to the Registry which subsequently spawns large numbers of processes. This ultimately degrades performance on both the Edge and Registry resulting in backed up queues and timeouts in processing.

If customers have not upgraded to HealthShare Information Exchange 2018.1 or higher, they can query the Relationship Registry for a count of rows. If there are concerns about the size of the table, please contact the WRC.

The correction for this defect is identified as dev key AJB104 and will be included in all future product releases. It is also available via Ad hoc change file (patch) or full kit distribution from the Worldwide Response Center (WRC).

If you have any questions regarding this advisory, please contact the WRC.
