MID Server on silicon based Mac (Mx)

[Tommy Jensen]

I need a local MID server to test an integration solution I am working on and I do not have windows anymore. And I do not have a license to run a virtual windows server.

So I have tried to build a docker image with the recipe downloaded from the instance b ut it fails with following error:

ERROR: failed to solve: eclipse-temurin:8-jdk-alpine: failed to resolve source metadata for docker.io/library/eclipse-temurin:8-jdk-alpine: no match for platform in manifest: not found

I have spent hours googling for a solution but so found none. For that problem I have created a HI case and am waiting for a response on that.


Then I found a blog post about how to run MID Server directly on siliconbased Mac so tried that too. But this too fails. I get these errors 

Unable to locate any of the following binaries:

/Volumes/DATA2/midserver/agent/bin/./wrapper-macosx-arm-64

/Volumes/DATA2/midserver/agent/bin/./wrapper-macosx-arm-32

/Volumes/DATA2/midserver/agent/bin/./wrapper

I found another post which said to grab those files from the Vancouver zip. I did that but then I get other errors and the MID server still cannot start.

Release: Washington DC 

Machine: Mac Studio M1 Ultra.

I'm not sure if it will work for you on the M1, but I have just managed to install a MID server on a Raspberry Pi 4, which is also an ARM architecture.

I have combined the Tanuki wrapper from https://download.tanukisoftware.com/wrapper/3.5.51/ into the MID service folder and added the Amazon Coretto 17 Java run-time to the MID service folder, have updated the configuration files to point to these new pieces, and it kinda' works.

The updated files were "wrapper-jvm.conf":

set.JAVA_HOME=/srv/snmid/agent/jdk-17.0.12
set.SNC_JVM_ARCH=arm-64

and "wrapper-override.conf":

wrapper.name=snmid_agent_001
# REQUIRED: Display name of the service
wrapper.displayname=ServiceNow MID Server (agent_001)
...
wrapper.java.command=%JAVA_HOME%/bin/java

The last parameter makes it use the Amazon Coretto 17 run-time.

The differences between the downloaded and final MID service package are that folder "bin" contains the extra file "wrapper-linux-arm-64" and folder "lib" contains extra (sub) folder "arm-64" and extra files "libwrapper-linux-arm-64.so" and "wrapper.jar" - all from the Tanuki download.

I have seen that the Tanuki download also contains Mac Arm files, but I can't say if any will work on the M1.

Something I just realized, maybe you should also download the "delta-pack" from Tanuki. It contains files that have the platfrom in their name so it will be easier to "combine" those into the MID service installation - will not cause conflicts. I can see that the delta-pack contains files "bin/wrapper-macosx-arm-64" (and library "lib/libwrapper-macosx-arm-64.dylib") which might be what you need. It may be that other library files will also be needed, but I have no way of knowing.

Thanks, I did discover that once I found the first missing files then more. But for now I managed to get a Vancouver MID server up and runnning. It turned out that the blogpost I linked to have a small but significant error in the description.

The linie

• wrapper.java.additional.128=Djdk.lang.Process.launchMechanism=posix_spawn

should in fact be

• wrapper.java.additional.128=-Djdk.lang.Process.launchMechanism=posix_spawn

the "-" was missing between "=" and "D".

You're most welcome 🙂

Glad that you managed to make it work.
