HL7 - FHIR

Hi All,

I know hundreds of people have done this but I'm looking for some DTL's as a start to do HL7 to FHIR, I appreciate everyone's HL7 is slightly different, but just some starter DTL's would be much appreciated? Can anyone help?

Hi Developers,

InterSystems is offering a new and easy challenge as part of Global Summit 2020. As you know IRIS Data Platform 2020.4 and IRIS for Health 2020.4 are now in preview release. We are looking to improve the developer experience in migrating from earlier 2020 container release(s) of these products to the 2020.4 preview release.

We invite you to complete a survey and get 7000 points on Global Masters🎁

This may not be the right place to ask, but I am having some issues with the VSCode setup. I have installed the InterSystems Extensions but I am not seeing the InterSystems icon on the Action Bar long the left side of the screen.

Can someone point me in the correct direction of what I need to do to fix this issue?

Thanks

Scott

Migrate from Java Business Host to PEX

Migrate from Java Business Host to PEX

With the release PEX in InterSystems IRIS 2020.1 and InterSystems IRIS for Health 2020.1, customers have a better way to build Java into productions than the Java Business Host. PEX provides a complete set of APIs for building interoperability components and is available in both Java and .NET. The Java Business Host has been deprecated and will be retired in a future release.

Advantages of PEX

I'm looking for the best strategy for extracting data from a Cache table that houses 86 Million lines of data and around 190 columns. I'm currently using DBeaver and the Invoice Service dates go back to 1996. Optimistically I'm looking to pull to a pipe delimited flat file, but even a year's worth of data takes many hours to get query results.

Any suggestions for the best practice/strategy?

Thanks,

John

Class Queries in InterSystems IRIS

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!

Hi All,

Can you please guide me on how to restore the .cbk file from the 2015 Cache version into the 2017 version or any other versions of Cache or IRIS software? I have a new instance on my server. It's an entirely new server. I have a .cbk backup file. I want to restore the backup file into a new namespace which one I will create on my new server. When I am trying on ^DBREST utility, I am getting "This is not a Cache Backup File" this error.

Please advise on this. It's a bit urgent.

Thanks,

Arun Kumar.

Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit. I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

Hi All,

I'm being asked if I can set up a AWS EC2 containerised version of IRIS and a separate AWS EC2 installation of Apache to serve IRIS web files.

Creating the Apache EC2 and containerised IRIS EC2 is the simple bit but getting them both to talk to each other does not seem quite so simple and I cannot find any documentation to describe how this can be achieved.

Has anyone else managed to achieve this?

Configure IRIS using Python

I am trying to configure IRIS using python. The first task I wanted to do it change the journal directory. I cannot figure out the right way to work with the Config.Journal class with python. I can get the text to query the current setting.

returnValue = dbnative.classMethodValue("Config.Journal","GetList")
print(returnValue )

But I don't see a straightforward way to parse the $List returned by GetList() I was hoping there was an easier way.

How do I

1. Query configuration parameters?

2. Set configuration parameters?

Using python?

$LIST string format and %DynamicArray and %DynamicObject classes

IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.

$LIST String Format
