Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

In our language we have scandic letters like ä (a with two dots on it).

In Angular we use login like this:

let headers = new Headers();

password = Base64.fromBase64(password);

headers.append('Authorization', 'Basic ' + Base64.encode(username + ':' + password));

Is there a group in or outside of this community for discussion of DTM issues? I am working on a conversion to Caché for a client but in the meantime, he is still live with his DTM system and a system management issue has arisen. The convo:

Client: Do you know how to increase the page limit in MUMPS DTM?  One version of my database I use for one customer is telling me I have reached my page limit.  I have increased the page limit in the database you are reviewing; so I figure there is a setting I am missing.

Configuring an Ensemble production can be a challenging task involving a thorough understanding of the system and production functionality and a detailed understanding towards each configuration item. After successfully configured an Ensemble production, you might need to set up an identical production on the mirror environment, or deploy the production on a development system to a live system, or send a copy for diagnostic/debug purposes. Other times you might have spent some time designing a BPL/DTL and some other productions can use the same logic.

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

 

I was thinking that Ensemble could maintain the SSH tunnel, 

which would improve our detecting of issues.

 

Has anyone done something like this?

I see that the  class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself.   Instead, it appears

Hi everyone,

before contacting WRC i thought to ask dev com about some questions related to Ensemble DICOM related implementation. These are more practical things and I hope to have someone around with experience in the field. We´ve created a DICOM Worklist application and are now in the process of roll-out.

Hello all.

I think the forum experience is great as whole, but it could improve even more if we had somewhere to share our ideas. So that's why I'm creating a thread dedicated for that purpose. Maybe this way someone from InterSystems could catch something good?

Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

 

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server.  It starts off as http, but then "upgrades" to web socket.  It then keeps open this "tunnel" for bi-directional communication..

 

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Hi community,

I am looking into a way to make Ensemble work as an AS/2 interface. So I would like to ask, if anyode did ever make AS/2 work with Ensemble and what is the way to go.

I found an old article regarding integration of third party interfaces (incl. AS/2 - http://www.intersystems.com/who-we-are/newsroom/news-item/intersystems-c... ) into Ensemble but no further mentions, neither in the docs.

Thanks

Jiri

Does anyone have a good example of setting up an Inbound Email Adapter Service to retrieve an email? I am thinking of sending this email to a BPL to retrieve the Attachment that is in the email. Would that be the correct method to do that?

Thanks

A customer wants to process D93A edifact files, orders and invoice. Does anyone have .SEF files available or know how to get them, so we can easily process them with Ensemble? Otherwise we would either have to write a parser for the two message types, or create a SEF file.

Any advice is welcome on this,

Marcel

Points to remember before you start: 

  1. It is not possible in a COS (Caché Object Script) job/process context to have multiple Named Pipes. It is a one Named Pipe per job/process limited line of communication. 

  1. Named Pipes, in Caché, like most pipes on most operating systems are Unidirectional. That means you open them for either Read or Write, but not both.

Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages).  Most HL7 services and operations have a Framing setting that allows the user to define this framing.  The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.

Hello community,

I have productions running in several different namespaces.  They all use a common credentials ID for sending email, which is set up in only one of the namespaces.  The documentation says that credentials are entered by namespace.  When I ran a production in a second namespace, the error log said that credentials were not found (expected), but later attempts to send a file thorugh the production did successfully send an email.  I'm wondering if Ensemble is able to look in other namespaces for the same credentials ID?

We have multiple implementations spanning many namespaces and edges.  I would like to see if I could identify a single place, perhaps on HSREGISTRY or HSBUS, that I could capture certain events like searches (from all customers) and record transfers (with requester and provider).  

The goal is to have a dashboard that would show simple stats such as searches by participant, records shared by participant and records consumed by participant.  These are the 3 most important.

I appreciated the feedback on the other question of "how" but now I'm hoping to find the "Where".

this is catching  me all the time, again and again...

Haven't worked with XML VDOC for some time, I can't figure out, what is the correct way of using Property path. Can someone please help me to refresh my memory.

Simple example: I have a class called Body, with Value and Topic properties. I created a XML Schema for this class and imported it into Ensemble. So i have a category called message, with Body as DocType structure and Name and Topic properties of Body complex type ($2:Value and $2:Topic are element names)

My rule looks this way:
