Subscription Failover recovery test

The purpose of this test is to verify that the client system can recover all missed trades in case of a disconnect or outage. The test uses LastUpdateTime (Tag 779) to help recover missed trades.

This test is mandatory.

  • To run the test
  1. On the Test Case tab, use the Instrument(s) drop down menu to choose an instrument and channel and click SELECT.

  1. Select START TEST.

Note: Do not select START TEST while a test is running unless instructed to do so. Restarting a test deletes the current test results.

  1. Submit an unfiltered Trade Capture Report subscription request (263=1). If using Tag 779, please use the current time.
  1. Receive Trade Capture Report messages. Validate LastUpdateTm (Tag 779) from the last trade received.
  1. Reinitiate the connection and request trades using a subscription request (263=1) and LastUpdateTm (Tag 779) that is at least one minute prior to the LastUpdateTm of the last trade received in step 4.
  1. Select Yes or No to confirm that your system received additional, new Trade Capture Report messages along with one or more previously sent Trade Capture Report messages, including a duplicate message from step 4.
