Option 6.3

List items.

Option 6.4

Query the Tracker Historical database.

Notes

  1. If a query fails, the Query Engine will display a message to report the failure and discards debug information. If you want to save the debug information you can create a global parameter SOLVEENGINEDEBUG to have the Query Engine write it to a file.

  2. By default, the Query Engine will try to get results to a query for 15 seconds. After 15 seconds it will stop and display a time-out message. You can change the length of time by creating a global parameter SOLVEENGINE_QUERY_TIMEOUT.

  3. You can query the Tracker Historical database instead of the TADB and Tracker databases. The Tracker Historical database can be used with any of the test options.
