Follow these steps if a total system restoration is required.
Step 1: Confirm Operating System Installation
Approved operating systems for the host server are found in the CygNet System Requirements document. For any operating system, the most recent service packs should be installed.
Step 2: Confirm the Server is on Network
The host server requires a static IP address. If possible, use the IP address that was assigned to the server that you are replacing. Client computers and other ARSs have knowledge of this address. If you cannot use the same IP address, you may need to manually connect ARSs and clients (see steps 8 and 9).
Step 3: Reinstall Services
Use the CygNet SCADA Services Setup program on the CygNet product source to reinstall the services. Be sure to use the same Site name, select the correct backup folder, and select all of the required Equipment Interface Engines. Using the setup program ensures that all DLLs are registered. You may have to create the folders and ARS entries for uniquely named or special services (OPCIS, replicated VHS, etc.)
Step 4: Restore Backup Files for each DBS-Based Service
Note: This step applies to the DBS-based services only, which include the ACS, APPS, AUD, BSS, ELS, ELSALM, DDS, FAC, GNS, GRP, MSS, PNT, and TRS.
Run the DBS Restore Backup utility for each DBS-based service. See DBS Restore Backup Utility for information about how to use this utility. See Step 6 for restoring the VHS.
Step 5: Copy Backup Files for Other Services
Copy the backup files for the other services to the newly installed services folders. If you don’t have a backup of the ARS or RSM databases and had custom entries in either you will have to manually re-enter the entries. If you are restoring a site in a multi-host environment, the ARS database should synchronize with the other ARSs in the system.
Restore the history data from the replicated VHS.
If the replicated VHS contains data from multiple sources, you will have to start an empty VHS and then use the VHS Import/Export utility to export the data from the replicated service to the new VHS. See VHS Import/Export Utility for more information.
Step 7: Restart Services
Use CygNet Host Manager to restart the services.
Step 8: Confirm Connection to Other Address Resolution Services
If you have a multi-host system, open CygNet Explorer and confirm that you can see the other sites. If you cannot see other sites, use the Connect ARS utility (ConnectARS.exe) to connect your ARS to another ARS.
Step 9: Confirm Client Connections to Host Server
Go to a client computer and open CygNet Explorer and confirm that you can see the site. If you cannot see the site or get a DCL error (can’t find directory service) run the CygNet Domain Connection utility to enter the IP address of the site’s ARS. See CygNet Domain Connection Utility for more information.
Step 10: Confirm Communication Port Connections
If the server is new, confirm that the peripherals are attached to the same communication ports as the old server. If the modem port assignments are different you will need to edit the GNS configuration file and/or the communication drivers in the DDS.
Step 11: Confirm Communications Hardware Operations
Confirm that communications hardware is operational (modems and other communication devices).
Step 12: Apply Patches
Apply any service and UIS device driver. Driver patches that were stored in the CygNet\Support folder may have been lost in the system loss, since the support folder is not backed up. These patches will need to be installed from a local copy or downloaded from the CygNet Software website.
Step 13: Install Clients
Use the CygNet Client Installer to reinstall clients on the host server. The services setup program will have created a shortcut for this program on the Start menu (Start>Programs>CygNet>CygNet Client Installer).
Step 14: XML Support
CygNet Software requires Microsoft Core XML Services (MSXML) 6.0 support. MSXML 6.0 is distributed with several older operating systems. If your services won’t start, it may be related to XML. If it is not pre-installed, download it from Microsoft (www.microsoft.com) to match your specific operating system and hardware platform and follow the installation instructions.
