Nice! What performance hit are we talking about? No way this level of detail is free.

%ALL namespace is another way to share routines/classes globally but without the need to modify CACHELIB/IRISLIB.

Encountered similar issue:

ERROR #743: CA certificate file is not valid [%OnValidateObject+97^Security.SSLConfigs.1:%SYS]

Turns out, Extension:basicConstraints field of the CA certificate must contain CA:TRUE. The BasicConstraints extension is intended primarily for CA certificates. It has a single Boolean variable, “cA”, which reflects whether or not the certificate is a CA certificate. If the certificate is a CA certificate, it can also declare a pathLen constraint that dictates how many sub-CAs are allowed to exist in the hierarchy of CAs.

To check:

Set bc=$System.Encryption.X509GetField(cer,"Extension:basicConstraints")
Write bc["CA:TRUE"

Yes, here.

Try to start Remote Gateway from the SMP and check the error there. Current error you see is caused by the fact that Gateway is not started or IRIS can't connect to it.

You need CONTENT=ESCAPE instead of CONTENT=STRING. Here's an example:

Class Utils.XML Extends (%RegisteredObject, %XML.Adaptor)
{

Property PACPROBLEMAS As %String(CONTENT = "ESCAPE", MAXLEN = "", XMLNAME = "PAC_PROBLEMAS");

/// do ##class(Utils.XML).Test()
ClassMethod Test()
{
	set obj = ..%New()
	set obj.PACPROBLEMAS = "1<2"
	do obj.XMLExportToString(.xml)
	zw xml
}

}

Produces:

<XML><PAC_PROBLEMAS>1&lt;2</PAC_PROBLEMAS></XML>

Great article!

For cases, where you don't want to share the source at all (even if it's immediately deleted), the following approach would work:

1. On your system (with source code) execute:

set p=##class(%Studio.Project).%New()
do p.AddItem("WH.Color.cls")
do p.AddItem("WH.Size.cls")
do p.DeployToFile("c:\test\app.xml",,1)

It will create an XML export with object code only and no source code included.

2. Transfer the file into a target system and execute:

set sc=##class(%Studio.Project).InstallFromFile("c:\test\app.xml")

APPCODE must be RO if you want to leave it in the container to be replaced as a part of the container.

Up to $zstorage size.

Great article!

Some notes:

1. SQL grants should be granted in a namespace with an SQL object.
2. SQL grants can be granted only to users and roles that exist.

If you log $lts(OutBoundlist) do you see the expected list?

Looks great. Where's the source for copy-data.py?

Can you run: do $system.Python.Shell() on a server?

Route to two BOs ("Normal" and "High" priority) with different FailureTimeout. Use SDS to keep other settings in sync.
