Snapshot Failover Recovery Test

The purpose of this test is to verify that you can recover all missed trades in case of a disconnect or outage using the Snapshot recovery process. The test uses StartTime (Tag 9593) to recover missed trades.

This test is mandatory if you selected “Trade Capture Report Request - Snapshot with StartTime (tag 9593)” in the interview question “Which type of recovery does your application support?”

  • 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 Snapshot request (Tag 263=0) and StartTime (Tag 9593) that is at least one minute prior to the LastUpdateTm (Tag 779) 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.
