If you check the MQ monitoring and it looks like this (messages are enqueued but seem not to be consumed by ABIS)

  1. Check the database status in your monitoring and in the logs
    • for example in trace.log 
      • o.h.e.jdbc.spi.SqlExceptionHelper ORA-01691
      • Failed to acquire connection to jdbc:oracle:thin 
  2. If input queues for ABIS have 0 consumers, check the status of Message processor or Fast services in your monitoring
  3. Make sure that your cluster was not reloaded recently (e.g. https://support.innovatrics.com/a/solutions/articles/13000077276)

Relevant ABIS version: 3.x - 7.x
