Diagnosing Framing Errors

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.

I'm running Windows 10 x64 Pro 20H2 with Intersystems Cache ODBC driver v2018.01.00.184. I've setup a System DSN using the 64-bit of ODBC Administrator.

I've been getting inconsistent results using my regular application (Microsoft Power BI) which I use through ODBC to query my hosted TrakCare T2017 instance.

Using Microsoft ODBC Test Tool (part of MDAC 2.8 SDK) I can verify I get the same errors as in Power BI. They seem to be ODBC driver related but I can't pin it down.

ODBC Test Tool GUI shows:

InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET.

EnsLib.HL7.Message.cls provides many API methods for manipulating an HL7 message. RemoveSegmentAt(), for example, can be used to remove a segment by path or index, but only one segment at a time. There may be times that you'll need to remove all segments within a group or even many groups of segments from the HL7 message. Surely you can iterate through each segment in each group and remove them one by one, but there's a much easier way.

With just one command, like below, you can remove all OBX segments in an ORU_R01 message (msg):

Hi-

I have a REST client that calls a REST service and as a response gets a stream containing a JSON structure. The service is placing some weird non-printable characters into some places in the JSON document that is throwing off parsing of a down-stream XML document.

What I would like to do is just remove the non-printable characters from the response stream that comes back from my call to the REST service.

Does anyone have a handy utility or method for removing all non-printable characters from a character stream?

Hey everyone,

I stumbled across a comment in this post that mentioned that the %SYS.GlobalQuery is a potentially faster alternative to %GSIZE. I tested it out and while I like the %SYS.GlobalQuery I noticed that it has some size discrepancies against a %GSIZE with details. Can anyone tell me which is more accurate for estimating the size of globals?

The DeclarativeCOS project is a heartfelt cry about programming in the COS language.

The purpose of the project is to draw attention of the public to improving the inner core of COS.

The idea of the project is the support of a laconic syntax for cycles and collections.

So what is this laconic something that I have come up with? Welcome to the examples below!

Examples

The key concept underlying the project is the declarative approach to writing code. You need to specify WHAT should be used and HOW.

Convert HL7 to PDF

Is there anything native in Ensemble that will support converting HL7 to PDF?

I see there are numerous examples in .Net and Java for this capability.

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

Docker 20.10.14 (released March 23, 2022) changes the Linux capabilities given to containers in a manner that is incompatible with the Linux capability checker in InterSystems IRIS 2021.1 (and up) containers.

Users running Docker 20.10.14 on Linux will find that IRIS 2021.1+ containers will fail to start and the logs will incorrectly report that required Linux capabilities are missing. For example:
