Hi Developers!

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

And now it's time to announce the winners!

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

I have a wdsl soap request that now requires a header. Where do I modify the header to allow this new value to be sent?

   <soapenv:Header>
    <Headers xmlns="urn:epic-com.2013.Interconnect.Headers"> 
      <Epic-Client-ID>12349fe5-2ff8-4b79-b723-e69efbabcdef</Epic-Client-ID>
    </Headers>
   </soapenv:Header>

Thanks

Scott

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

ClassMethod testInsert()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))
  hang 15
  &sql(ROLLBACK)
}

ClassMethod testRead()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED)
  &sql(select count(*) into :ans from Test.Table)
  &sql(COMMIT)
  w !,ans
}

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble. Those messages are then transformed and routed to an Operation which calls a web service which does a number of different activities. If will do address normalization, location geo coding, MPI lookup and resolution, and insert into a SQL Server database to stage for an analytics product. Unfortunately all of this work takes time and the first thing that happens in the web service is a lock taken out on the Patien in SQL Server.

Hello!

Not opening an instance by index key after CACHE migration to IRIS. In composite indices, when one of the values is null, when using idx open it does not return the reference.

Has anyone had this problem?

Hello,

first of all thanks for your time reading this question, and thanks for your time:

We are expected to send a file as an attachment in a SOAP request using MTOM protocol.

It is expected to include a "name" parameter inside the "Content-Type" header, as we show below:

Challenges of real-time AI/ML computations

We will start from the examples that we faced as Data Science practice at InterSystems:

• A “high-load” customer portal is integrated with an online recommendation system. The plan is to reconfigure promo campaigns at the level of the entire retail network (we will assume that instead of a “flat” promo campaign master there will be used a “segment-tactic” matrix). What will happen to the recommender mechanisms? What will happen to data feeds and updates into the recommender mechanisms (the volume of input data having increased 25000 times)? What will happen to recommendation rule generation setup (the need to reduce 1000 times the recommendation rule filtering threshold due to a thousandfold increase of the volume and “assortment” of the rules generated)?
• An equipment health monitoring system uses “manual” data sample feeds. Now it is connected to a SCADA system that transmits thousands of process parameter readings each second. What will happen to the monitoring system (will it be able to handle equipment health monitoring on a second-by-second basis)? What will happen once the input data receives a new bloc of several hundreds of columns with data sensor readings recently implemented in the SCADA system (will it be necessary, and for how long, to shut down the monitoring system to integrate the new sensor data in the analysis)?
• A complex of AI/ML mechanisms (recommendation, monitoring, forecasting) depend on each other’s results. How many man-hours will it take every month to adapt those AI/ML mechanisms’ functioning to changes in the input data? What is the overall “delay” in supporting business decision making by the AI/ML mechanisms (the refresh frequency of supporting information against the feed frequency of new input data)?

It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

As previously announced, 2017.1 on VSI OpenVMS 8.4-1H1 is the final major version of Caché and Ensemble. 2017.1 will not be available for VSI OpenVMS versions beyond 8.4-1H1.

Hi guys,
I've setup an FTP passthrough service and operation to move two files from one SFTP server to another.
The files are moved and i can confirm with filezila that the whole operation went well.
However, i need to raise errors and send email if one the sftp servers is down for whatever reason, and if the trasnfer didn't go well.
I ticked the alert on error box for the passthrough BS and BO and the errors are indeed forwraded to an alert management system. I have real problems with the check on the SFTP servers.

I am trying to get the time difference between two time stamps one is recorded earlier to the one happening current but the problem is sql expect string while I have the other stored in a variable and if I do the following I get errors any help please

&sql(SELECT {fn TIMESTAMPDIFF(SQL_TSI_HOUR,$ZDT($H,3,1,3),tx)})

please note that tx is a variable holding the time formatted the same way as the one being compared to

Let's say I have a global named ^a and I need to export its nodes 1, 2, 3, 5 only.

Currently I write something like this:

Write $SYSTEM.OBJ.Export("a(1).gbl,a(2).gbl,a(3).gbl,a(5).gbl", "C:\Users\eduard\Desktop\a.xml")

Is there a way to write it shorter? I want to write global node once and list all the subscripts I need.

IRIS 2010.1 brought us a new feature: %Net.WebSocket.Client

As a continuation of my series of WS Clients I just couldn't resist to try it.
Well, this is the result and it was rather simple in the end.

• After I succeeded in my personal fight against Windows Firewall ;-)

You basically need to prepare 3 classes:

Does anybody know if there is a wizard to create SOAP client/server web services for IRIS from VS Code? I would like to not use Studio anymore but for SOAP web services looks like there is no alternative in VSCode.

Thank you in advance!
