7.4 Procedure for replacing relay systems
Replacing a relay system means to migrate the functionality of an existing computer that is functioning as a relay system to another computer.
To replace a relay system, you need to back up the information on the computer being replaced, and restore it to the new computer.
To back up information on the computer being replaced:
-
On the relay system you are replacing, stop the relay system service.
-
Open the command prompt, and execute the following command:
relay-system-installation-folder\bin\dmpstop.exe
-
Using Task Manager or a similar tool, make sure that the processes below have stopped. If any of these processes are still running, wait for them to stop.
-
jdngdmpsetup.exe
-
jdngwinst.exe
-
jdngsite.exe
-
jdngschserv.exe
-
jdngsrvmain.exe
-
-
On the relay system being replaced, back up the following registry entries:
- For 32-bit operating systems:
-
HKEY_LOCAL_MACHINE\SOFTWARE\HITACHI\JP1/IT Desktop Management - Agent\DMP
- For 64-bit operating systems:
-
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hitachi\JP1/IT Desktop Management - Agent\DMP
-
Back up the following files:
-
Files under relay-system-installation-folder\MASTER\DB
-
Files under relay-system-installation-folder\SCHEDULE
-
Files under relay-system-installation-folder\SERVER
-
Files under relay-system-installation-folder\SITESRV
-
Files under relay-system-installation-folder\DMPSITE\\COLLECTION
-
Windows-installation-folder\jdnagent.nid
-
-
Start the relay system service on the relay system being replaced.
-
Log off from the relay system computer, and then log in again.
The information on the relay system being replaced is backed up.
To restore the backed-up information to the new computer:
-
Install the relay system program on the new computer.
When the installation process is complete, the Setup window appears.
-
In the Setup window, click the Cancel button.
-
Stop the relay system service on the new computer.
-
Open the command prompt, and execute the following command:
relay-system-installation-folder\bin\dmpstop.exe
-
Using Task Manager or a similar tool, make sure that the processes below have stopped. If any of these processes are still running, wait for them to stop.
-
jdngdmpsetup.exe
-
jdngwinst.exe
-
jdngsite.exe
-
jdngschserv.exe
-
jdngsrvmain.exe

Restore the backup information to the new computer.
