1.  Hot standby . To operate 'hot' standby where the full number of Progress and ProStix users are loaded on the remote DR server requires the user to pay a redundancy license fee of 50% of both the Progress and ProStix licenses. In the case of server failure, comms lines are switched to the DR server and the system continues with only minimal downtime. AI transfers would be continual and data loss in case of failure would be small if at all. 2.  Warm standby . To operate 'warm' standby would require a Progress database license (either Workgroup or Enterprise depending on what you are running on your main server) for a minimum of 5 users and at least one ProStix license. The AI file is applied at defined intervals to the remote DR server and in the case of main server failure, the warm DR server would assume control after the Progress and ProStix maximum user counts are installed (via the running of scripts).2 3.  Cold standby . There are no licensing implications with cold standby provided the server is restored from backup AFTER the main server has failed. No Progress or ProStix users may be loaded on the DR box while the main server is operational. Technical Restrictions for After Imaging 1. DR server must run exactly the same Network Operating System and Progress database as the main server. 2. The database on the DR server must not be accessed. After Imaging requires complete integrity of all indexes as at the last application. 3. After the AI file is applied to the DR server, the database is copied and this copy may be accessed for interrogation, testing, training or reporting purposes. The cost includes:  1. A Progress 5-user Enterprise or Workgroup database license. 2. 1 ProStix license. 3. Installation and training to the point where the DR server is fully operational and scripts installed and working. This service can be conducted remotely, but clients may prefer an on-site installation to ensure all printers and communication devices are working. Our recommendation is that this server be utilised as a testing, training and reporting environment to take pressure off the main server. Additional time may be required if the reporting options are installed. Additional ProStix users may be required.
