Remote Engine installation on Windows, without changing 'path' and 'JAVA_HOME'.

[Luigi_Teti]

Hello,

I have to install an RE on a windows server where JRE 1.8 is installed and we do not have to touch the JAVA_HOME config and path, because of some scripts currently running on the server.

I ran a simulation on a test environment and successfully paired the Remote Engine.

Below are the steps followed, I wanted to know if this seems to be a correct procedure:

1. Downloaded the installation zip of the RE

2. I installed JDK17, using Azul Zulu and removing the ticks I did not want:

3. Created the RE on the Cloud and modified the two local files for the “pairing.service.url” and “remote.engine.pre.authorized.key”

4. From CMD, before starting the wrapper that checks for JDK17 installed, I configured the two temporary variables:

• set "JAVA_HOME=C:\Program Files\Zulu\zulu-17\"
• set "PATH=%JAVA_HOME%\bin;%PATH%"

5. From the same Prompt I ran the wrapper (shell.bat wrapper:install -n Talend-Remote-Engine)

6. I edited the file “Talend-Remote-Engine-wrapper.conf’ created, modifying:

• Explicit JDK17 path for the variable “wrapper.java.command” (without this step, the service would start but from the karaf log I had an error indicating that it was not 'pointing' to JDK17):
• Modified the JVM memory (I put 2GB) 

7. Created the service with “Talend-Remote-Engine-service.bat install”

8. I don't think it is influential, I then edited the service name on Windows because it creates it for me with the display name 'karaf' and then I did:

• sc config "Talend-Remote-Engine" DisplayName= "Talend Remote Engine"
• sc description "Talend-Remote-Engine" "Talend Remote Engine"
•
