The query file specifies Sources, cameras and time periods for archive replication. This file is created on the Target. To create the query file the following conditions are to be met:  

1. Users are created in the Axxon PSIM™ (see User registration and removal section).

   Users with the same name and password are to be created on Source and Target for stable operation of the Data replication service.

   
   

2. Corresponding rights are assigned to users (see Registration of users' rights section).
3. At least one Camera object is created in the Target hardware tree.

The query file is created using the schedule.exe utility (see The shedule.exe utility for creating a replication query file section).
