I'm receiving a JSON payload via a REST API, I'd like to %JSONImport this stream into a class which extends %JSON.Adaptor. The problem is that the JSON is an array whose elements have no key (as you can see in the example JSON below). Right now I'm having to do some manipulations to convert the stream into a dynamic object and do a %Set which inserts a made up key "record" so "thingone" and "thingtwo" have an associated key that I can use when referencing "thingone" and "thingtwo".such as record.

Can you please provide the package for adding new column in the FHIR table using additional package for the boolean datatype.

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON 

Please provide all the code for all three file for boolean datatype.

I have created a BPL to process a file and create a lookup table. I am looking to add logic to use the original filename so that I can use a single BPL to create multiple tables. How can I access the original filename within a BPL?

In part I of this article, we have already learned more about HL7, its messages, structure, segments, and fields. In this part II, we will show you how to transform proprietary/custom data into HL7 using IRIS for Health. For our sample, we used the data generated by the SYNTHEA bulk data generation project (https://synthea.mitre.org/downloads). So, we will show you how to convert 1000 patients from a CSV file to HL7 v2, using the Interoperability features of IRIS for Health.

EHR (Electronic Health Record) systems are designed in a proprietary format/structure and are not based on such market models as FHIR or HL7. Whereas some of those systems can interoperate data in a proprietary format for FHIR and further market models, others cannot. InterSystems has two platforms that can interoperate proprietary formats for market standards: InterSystems HealthShare Connect and InterSystems IRIS for Health.

Hi all

I'm having trouble defining the mapping needed to take the very large base64 string in OBX:5.5, and map it to an XML virtual document property that supports Stream.GlobalCharacter. I know from within the DTL you have to use custom code to manage the segment due to its size. 

do target.StoreFieldStreamRaw(.stream,"LetterAttachment(1).Base64EncodedFile(1)", .rem)
 set tObx14Value = $piece(rem,"|",10)
 set convertedDate = ##class(Phu.Shared.Util.DateTime).ConvertHl7DateTimeToXmlDateTime(tObx14Value)
 do target.SetValueAt(convertedDate,"DocumentDetails(1).AuthoredDate(1)")
 do target.

In the world of Big Data, selecting the right file format is crucial for efficient data storage, processing, and analysis. With the massive amount of data generated every day, choosing the appropriate format can greatly impact the speed, cost, and accuracy of data processing tasks. There are several file formats available, each with its own set of advantages and disadvantages, making the decision of which one to use complex. Some of the popular Big Data file formats include CSV, JSON, Avro, ORC, and Parquet.

We are using IRIS health 2023.1 to build an application that runs on kubernetes cluster as container images. In the container image, we have our own PRODUCTION "APP" created with its routines database and global database located at:

/usr/irissys/mgr/APPCODE/IRIS.DAT

/usr/irissys/mgr/APPDATA/IRIS.DAT

To persist the data, we use the “Durable %SYS for Persistent” featureand set the ISC_DATA_DIRECTORY to an external durable folder (/durable/iconfig).

To resolve the error <PROTECT>, remove the read-only attribute of the system-wide library database (IRISLIB for InterSystems IRIS, CACHELIB for Caché/Ensemble/HealthShare (Caché-based))

Once you have finished importing the routine, remember to change it back to read-only.

IRIS has the likes of SQL inbound adapters for use with SQL gateways such as EnsLib.SQL.InboundAdapter to repeatedly query SQL Gateway connections. A scenario appeared as that we wanted to query an Internal database for some data but did not see an out of the box service for this. 

Have a Generic service that can poll internal SQL to work with downstream components.

What was not clear was "How do I send a result set downstream".

I have an interface with repeating DRG segments with messages coming in as DRGgrp().DRG(1). I know how to find the count of DRG groups:

 (source.{DRGgrp("*")}) BUT I am stuck at how to find the index of the segment that has DRG.1.3 having a specific value = "PMP". Any ideas please?

Thank you

I am often asked by customers, vendors or internal teams to explain CPU capacity planning for large production databases running on VMware vSphere.

This post was originally written in 2017, I am updating the post in February 2026. For context I have kept the original post, but highlighted changes. This post was originally written for ESXi 6.0. The core principles remain valid for vSphere 7.x and 8.x, though there have been improvements to vNUMA handling, CPU scheduling (particularly for AMD EPYC), and CPU Hot Add compatibility with vNUMA in vSphere 8.

What changes are to be made while customizing a FHIR server package when adding a new field. As provided in the documentation, we have a sample JSON package of favorite color and it is added in the table, but when we are adding a new field 'Insurance', it does not imports the package and says package already exists. We have three files of JSON 

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON 

What should we have to change for adding new field.

I restore the “dirty” copy of the IRIS.DAT files, then apply the incremental backup as documented for Online Backup. As shown in the picture, restarting the service before mounting and rejoining the database to the mirror can restore the mirror database to the point in time of dirty data. I think the mount method used here is the default value, and I don't want it to perform mirrorcatchup. Is there any other way to recover the mirrored database to the point in time of dirty data？

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect. 

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

Trying to setup my first OAuth 2 client to authenticate against Epic's Interconnect instance that is hosting FHIR/Web Service API's. Epic's documentation says the JWT request has to be sent as a POST request..

Does 

GetAuthorizationCodeEndpoint

and 

GetImplicitEndpoint

automatically put the request into a POST request, or do I need to format a %Net.HttpRequest to POST?

Thanks

Hi Community, 

Can I please check if any one is aware of any functionality in HealthShare to verify NHS Number check digit.

We are trying to implement the NHS Number check digit validation using Modulus 11 Algorithm ( described here : NHS NUMBER (datadictionary.nhs.uk) ) 

I wanted to check if there is any built in option available or if anyone has implemented something similar using Object Script. 

Thank you for your help.

I made a custom application metric, imported it to the USER namespace and used:

set status = ##class(SYS.Monitor.SAM.Config).Add.ApplicationClass("historymonitor.errorSensor", "USER")

to add it. When I do 'w status' it returns 1 so it is added but I still can't see the custom metric in the api/monitor/metrics endpoint. Even though I added %DB_USER in the application roles for api/monitor.

Does anyone know where the problem might be that the metrics endpoint still doesn't show my metric?

This question originally appeared in the comments of the post: Making use of Multiple Sub Transforms in a main map || HL7
 

I'm having a similar problem trying to get PRD(1) into PV1:ReferingDoctor and PRD(2) into PV1:ConsultingDoc
Running the subtransform will populate referring doctor for the first PRD, and then the second running will delete the PV1, make a new one with only the consulting doctor populated.

Was hoping I could use a subtransform to populate the information, but looks like it has to be done at the transform level.
