Summary | Some TISSS trainee profiles have incomplete Programme Membership data |
Impact | TISSS trainee profile data missing for some trainees |
Non-technical Description
Trainee profile data is copied into TIS Self-Service from TIS. This happens whenever data is added or updated in TIS. Our monitoring tool alerted us that some TIS programme membership data was repeatedly failing to be loaded successfully into TIS Self-Service. The issue arose on 28 Dec 2023, and was resolved on _____.
Trigger
(To confirm) The ID’s of some CurriculumMembership records had changed. We use the ID’s as a primary key. (The assumed consequence of this might be duplication in TSS, not a failure to sync the data successfully, so this needs to be clarified)
Detection
CloudWatch Alarm in the #monitoring Slack channel for messages in the tis-trainee-sync-prod-dlq (Since 2022-12-28 10:23:34)
