Is it works on the same host or not? Server and odbc  client

$system.OBJ.OpenId(class,id)

$classmethod(class,”%OpenId”,id)

I have not played with the Foreground feature before, but, I tried to do it right now, and it looks like, you can just publish port 63300 when you run the container, so, your host's telnet client will be able to connect to the Foreground port. 

If you wish, you can change the port number, by setting it directly to the global

Set tPortRangeStart=$G(^Ens.Config("FGTelnetRange","start"),63300)
Set tPortRangeEnd=$G(^Ens.Config("FGTelnetRange","end"),63499)

When you have ISFS configured to multiple namespaces, you can just use copy-paste ability to copy files between isfs folder, or with using real folder.

Link to documentation

Local way, is actually how it was designed by default, and how you'll get the best experience.

What issues did you face? 

In short how to start using it.

• You need to configure access to your server through parameters under "objectscript.conn"
• Use your local code, if you already have it, or export code from the server, once you are connected
• Edit and save files as a usual file, will save it on the server and compile it, in case of any compilation issues it will notify you about it.

You have to look at grade documentation. And it will be something like this. it says, to look at libs folder for jar files, usually it only uses some remote repositories like maven central

repositories {
    flatDir {
        dirs 'libs'
    }
}

I found only this way when it's working. __name__ will have current classname 

Class User.Test
{

ClassMethod SomeMethod() As %String
{
  quit "test"
}

ClassMethod PTest() [ Language = python ]
{
  import iris
  print(iris.cls(__name__).SomeMethod())
}

}

Do not use %ZEN, it’s deprecated. There is Native JSON support, and %JSON.Adaptor, use this instead. Any output with write command will produce this error. 

%ToJSON has three ways. One of the is to output through String, as you did with Write command.

In your case you can simply use Do command instead, and it will just output to the current device directly, without collecting it to a limited variable.

Or you can do through the stream, passed as a first parameter

Do you use Windows, macOS or linux?

ndjson, is just when a bunch of ordinary JSON separated by a newline in one file

So, if you would read that stream with ReeadLine(), and parse each line separately, it should work.

$translate(string,$char(49824))

Mount such folder as a network disk, and you can use it. Just be aware, that you have to mount it under the right user, which runs IRIS.

if you managed to access ManagementPortal, what exactly are you trying to achieve?

0.0.0.0:1972->1972 means that any it mapped to any IP on your host.

Hmm, why do you need to do it with .bash_profile? Why not just set it as a shell, instead of bash

And about passwords, the best and only right way in your case is to enable OS-Authentication. In this case users will go inside without a password prompt.

Just install a newer version over that old one, and everything will be ok. In some cases, it is possible that some changes in code would be needed. And you may look at the documentation for some information about the release
