7.6 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.
In Control Panel - Administrative Tools - Services, stop the Agent service (JP1_ITDM2_Agent Service). Note that the Agent service can be stopped only for the relay system.
-
Make sure that the processes below have stopped.
When you stop the agent service, the following processes stop. Using Task Manager or similar tools, make sure that the following processes are not displayed. If any process is still displayed, then the process is still running, so wait until the process ends and the display disappears.
-
jdngdmpsetup.exe
-
jdngwinst.exe
-
jdngsite.exe
-
jdngschserv.exe
-
jdngsrvmain.exe
-
-
On the relay system being replaced, back up the following registry entries:
The back up of the registry can be performed by launching the OS feature Registry Editor and exporting the 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

Manually back up the files and folders under the following path.

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
-
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.
In Control Panel - Administrative Tools - Services, stop the Agent service (JP1_ITDM2_Agent Service). Note that the Agent service can be stopped only for the relay system.
-
Make sure that the processes below have stopped.
When you stop the agent service, the following processes stop. Using Task Manager or similar tools, make sure that the following processes are not displayed. If any process is still displayed, then the process is still running, so wait until the process ends and the display disappears.
