I  have java  language experence. If I need parse a binary tcp packet . like following format

encoded string and send it to peer by tcp

1byte msg type + 4 byte(unsigned int) + raw byte(body)

To parse this package , Some Java code like this:

byte[] data = new byte[1024];

Bytebuf buf  = new ByteBuf(data)

byte type = buf.read()

int len = buf.ReadInt()

byte[] bodyBuff = new byte[len]

buf.Read(bodyBuff)

String str = new String(strBody)

So, does Objectscript have similar functionality to achieve similar results?

Tks.

Hey Developers,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in August 2020:

I’m interested in our DeepSee references who define cubes with external databases.

Hello,

I would like to schedule the Database Compact and Freespace methods as legacy tasks.

Has anyone implemented this yet?
Is this even possible? 

The request for this is due to the fact that we have 3 interfaces in a namespace whose messages are deleted after 7 days. All other messages in this namespace should be kept for one year.
This leads to a certain fragmentation. Furthermore, the messages to be deleted are relatively large (MDM^T02 > 32MB), which in turn leads to a fast growth of the database size. 

How would you solve this problem?

With kind regards

Armin Gayl

Error management on InterSystems languages has been evolving along time. Next, we will show the different implementations and why you should use the TRY/THROW/CATCH mechanism.

You can read official error recommendations here.

InterSystems will not mark as obsoletes the non-recommended error management methods to allow giving support to legacy applications. We recommend using tools like objectscriptQuality to detect that legacy unrecommended usage along with many other possible issues and bugs.

I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?

Just like the title, I want to do code version control. I don't want to change CLS at will, but I don't want to use MakeClassDeployed, I just want to set the cls or mac to read-only and uneditable state。Does CLASS have such property?

Hi All

I am writing a class to take a general HL7 replace the non ASCII characters in all the segments to construct another message.  I have the following solution working to an extent however it is inserting \r at the end of the segments that have been transformed.  Firstly is this the correct approach and secondly how do I get rid of \r at the end of the segment that is affected?

Thank you for your help.

ClassMethod Transform(source As EnsLib.HL7.Message, Output target As EnsLib.HL7.Message) As %Status
{
Set $ZT="Trap",tSC=$$$OK
Do {
Try {
#Dim tMSHin As EnsLib.HL7.Segment
#Dim tSegIn As EnsLib.

I need to consume the content of ^SPOOL output over SQL.
^%SPOOL utilities don't look so promising

I'm trying to parse some XML but I ran into an issue where my data has a / in it (see below).

<pArray index="0">/shared/BENANDERSON</pArray>

When I ran it, I got this error.

Here is the code where I found the issue occurring. The XML reader must see the / as the invalid character. The value of P0 eventually ends up as null which causes another issue downstream. Is there a way for me to proceed with the / in the data? Thank you!

do %request.Content.

This message contains two recent HealthShare Advisories, which are available below.

• Advisory: Consent API allows for the creation of consent policies for non-existing MPI IDs
• Advisory: Issue with Consent Processing in the Operational Data Store

These advisories are also on the InterSystems Product Alerts and Advisories page

September 1, 2020 – Advisory: Consent API allows for the creation of consent policies for non-existing MPI IDs

InterSystems has corrected a defect when using the Consent API, where it is possible to associate a consent policy with an MPI ID that does not yet exist.

I am trying to compare times on an IRIS instance. The times are in the W3C format (https://www.w3.org/TR/NOTE-datetime). Are there any in-built helper functions in IRIS to support time comparisons in this format or will I need to parse it using functions such as $zdateh and $ztimeh to do the comparisons?

Hello,

Recently I tried to connect to JDBC on IRIS 2020.3+ and I came across the following error:

 SQL Error [461] [08S01]: [InterSystems IRIS JDBC] Communication link failure: Communication error: Server closed communication device

This error implies that the port is not open.

Checking with the netstat command:

irisowner@78c3e30b7f41:/opt/irisapp$ netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State

tcp 0 0 0.0.0.0:52773 0.0.

I have a list of 300 code combinations in the following format, which I plan to load into a global

X123, Internal health

X234, external health

X345, Peripheral health etc..

I want to get the code from the DG1 segment, compare to the global, and add a description. Is there an easy way to do it?

So in my DG1 segment If I get the code X123, what I want to do is check if the code is in the global and if it does add the description in the field.

So DG1 will look like this:

Keywords:  IRIS, IntegratedML, Machine Learning, Covid-19, Kaggle 

Purpose

Recently I noticed a Kaggle dataset  for the prediction of whether a Covid-19 patient will be admitted to ICU.  It is a spreadsheet of 1925 encounter records of 231 columns of vital signs and observations, with the last column of "ICU" being 1 for Yes or 0 for No. The task is to predict whether a patient will be admitted to ICU based on known data.

This dataset seems to be a good example of what's called "traditional ML" task. The data seem to have the right quantity and relatively right quality.

Hi Developers!

The InterSystems IRIS for Health FHIR Contest is over. Thank you all for participating in our FHIR Competition!

And now it's time to announce the winners! 

A storm of applause goes to these developers and their applications:

Caused by a conflict in the port assignment I get this  entry in mesages.log and SMP doesn't respond:

The first line is true, the second is just wishful thinking

Hey Developers!

This week is a voting week for the InterSystems IRIS for Health FHIR Contest!

So, it's time to give your vote to the best FHIR solutions built with InterSystems IRIS for Health.

🔥 You decide: VOTING IS HERE 🔥

How to vote? This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

The fhir-react project defines a unique component which renders the interface based on FHIR resource type. There's no need for any configuration because the library uses the standard of defined by the resource type.

So, I decided to apply the same idea, but for charts. The basic idea is depicted below:

For instance, some FHIR resources like Observation, Condition etc., has a code. Thus, we can aggregate all codes and count them.

Such aggregation creates a standard data model.

Finally, this model could be adapted for any char library.

I use these example classes:
Class Sample.Address Extends (%SerialObject, %Populate)
{Property Street As %String;
Property City As %String;
Property State As %String(POPSPEC = "USState()");
Property Zip As %String;}
Class Sample.Person1 Extends (%Persistent, %Populate)
{  Property Name As %String;
Property Home As Sample.Address;
Property AR As array Of Sample.Address; }

In SQL it is Table Sample.Person1

No problem to define INDEX on Home_State

But Table Sample.Person1_AR

HowTo define an INDEX on AR_State ?
Index st On AR.State;

Does not compile!

The fhir-react project is a React UI framework based on Google Material Design, which covers almost all FHIR resources for versions DSTU2, STU3 and R4.

It design it's really friendly - there's just one component! As FHIR resource types are standards, the framework resolves internally what rendering class must be used.

To display your FHIR resource just write this component:

<FhirResource fhirResource={fhirResource} fhirVersion={fhirVersions.STU3} />

Where fhirResource is a JSON containing any FHIR resource.

I am able to get a service class property  DISPLAYLIST into the SETTINGS PARAMETER using the below example from the documention but I am not able to get an adapter property in the same manner. Is there a way to obtain the DISPLAYLIST values from an adapter property into the SETTINGS Parameter?

for reference I am extending the adapter:  EnsLib.HL7.Adapter.TCPInboundAdapter

Example from documentation:

selector?context={Ens.ContextSearch/getDisplayList?host=@currHostId&prop=Framing}

Thanks,

David

As I said in the previous article, I started to learn about FHIR for the contest, and I'd like to share an update in my application: detection of inconsistencies in FHIR data.

Note: This document it's also availble in GitHub.

A useful usage for FHIR unified schema is search for inconsistencies. As suggested by @Qi Li, one example could be find patients with records for diabetes medication, however, without diabetes condition.

Another example is search conditions with findings (like diabetes, for instance) and a record for resources denoting "no known problems", e.g.

Hi Developers!

Here're the technology bonuses for the FHIR programming contest that will give you extra points in the voting:

• FHIR Server REST API usage 
• The usage of SQL Schema of FHIR Resources 
• Healthcare standards data transformation
• Docker container usage

See the details below.

Hi,  

In my previous articles, one of the most exciting things about FHIR that I mentioned it's the wide range of possibilities that we have and not only for creating something but the ways to achieve this goal.

For the FIleSpec on a file service can you use a multiple wildcard values like *CLINICALENCOUNTER*.xml?

It seems like you are restricted to a single wildcard value.

Introduction

Nowadays, there is a lot of applications that are using Open Authorization framework (OAuth) to access resources from all kinds of services in a secure, reliable and efficient manner. InterSystems IRIS is already compatible with OAuth 2.0 framework, in fact, there is a great article in the community regarding OAuth 2.0 and InterSystems IRIS in the following link here.
