Hello everyone,

I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.

Message Count

Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)

I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date

Select Sum(MsgCount)

From

(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount

FROM ENS.MessageHeader

Hi ,

I have a scheduler task and an associated class that works.

Class Sample.Util.CreateTask Extends (%SYS.Task.Definition, %Persistent)
{

Parameter PROPERTYVALIDATION = 1;

Parameter TaskName = "Sample.Util.CreateTask";

Method OnTask() As %Status
{
// Perform the logic
}

}

Is there a way to Enable or Disable the above task "CreateTask()" from an external function/Method/class ?

I have created a class file that I want to execute daily to gather Metrics (Message Header, Space Available, etc..) and write the data into a Cache table. Now that I have written the class I want to add it to the Task Scheduler within Ensemble to run every morning. How do I go about getting the class file created as a Task within the Task Scheduler? The Documentation isn't as clear cut for creating custom tasks as one would expect.

At the moment we're creating multiple BPLs are using a router (or another BPL) to direct to these based on a unique key modulo the amount of BPLs available, e.g. if we have 3 BPLs created.

Message key = 1 mod 3 + 1 -> BPL02
Message key = 2 mod 3 + 1 -> BPL03
Message key = 3 mod 3 + 1 -> BPL01

FIFO only matters in that each messages for each key is processed in order.

We are using a DTL transformation to take HL7 and transform into custom XML (XML is a virtual document, held in an EnsLib.EDI.XML.Document object). The schema specifying the format of the XML says one element should occur no more than 24 times (maxOccurs="24" in the XSD schema). However, the transformation to produce one such element always produces 24 elements, all but the last one blank, when tested stand-alone.

uu-encoded?

We have a vendor that can only send us a uu-encoded PDF. Is there a way to decrypt it in Ensemble?

Thanks

We are currently looking into a way to provide a group of end-users (i.e. non-Interface Development engineers) access to a pre-defined group of Ensemble-based Data Lookup Tables for purposes of viewing and editing. We do not want to give them access to ALL Data Lookup Tables due to security/continuity concerns.

My thinking is that a simple persistent Cache table with three columns (Role Name, Table Name, Access-Level [like View or Edit]) with a CSP front-end could potentially provide an easy way to make this solution a reality.

Hi Guys,

how do I know that my service is running in a production, I've this receiving service and the as blow that says lost TCP then closing TCP connection, then last one says ConfigItem starting job, and in the Jobs tab it says Listing.

I'm attempting to streamline a process for renaming PDF documents received from multiple vendors to conform to a specification provided by an EMR vendor for ingestion. Things like Document ID, Document Type, Date of Service, Account Number, MRN, etc. all must be included in the filename at defined offsets and lengths. Most of the required values can be extracted from the inbound file's name and the few remaining are static values that would be the same (or handled via a lookup table based on source) for all documents.

Is it possible to generate INFO level logging events from within a routing rule?

TRACE level events and debugging are easy enough, but we have a case where we have a rule where we want to log messages that are not routed for further processing in the event log as INFO events - in production tracing will be turned off, so TRACE level events won't be visible.

Nested queries

Hi Guys,

This Nested query is not working for some reason, but they work fine when executing separately ?

select id from FDRD_Com.List where vehicle in (select Car from FDRD_Com.Prod where ProductLineName='Toyota' and Car is not null)

Thanks

I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.

My first question is whether this is actually necessary?

Hello,
Please, we would need your help 🙂:

In a development environment, we have added quite a few presentation contexts to the DICOM configurations (the associations). We would need to find a way to export them from this environment to make it easier for us to import them in PRO (and avoid doing it by hand one by one).
