In this article, we will explore the development of an IRIS client for consuming RESTful API services that have been developed to the OData API standard.

We will be exploring a number of built-in IRIS libraries for making HTTP requests, reading and writing to JSON payloads, and seeing how we can use them in combination to build a generic client adaptor for OData. We will also explore the new JSON adapter for deserializing JSON into persistent objects.

Working with RESTful APIs
REST is a set of engineering principles that were forged from the work on standardizing the world wide web.

In MX any global can be displayed on a sheet in the form of a table.

We will look at the simplest example (work only with  CACHE-2014+ or IRIS)

Upgrade or install  MX.

Start mx.xlsb  and connect to your namespase with vmx-routines.

After opening first sheet, click button  []   ##class(SYS.Stats.Dashboard).Sample()

Then press button [design-mode]   (top of screen ).

You will see something like this in the top four lines:

M-Formulas works in cells in the process of opening this sheet,  step by step :

• - go to the namespace %SYS    ( zn “%SYS” )
• - set dashboard=##class(SYS.Stats.Dashboard).

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

I am using the Java Binding to connect a Java Middleware Application to Cache.  Originally I was using a CacheListOfDataTypes (JAVATYPE = "java.lang.List") object to bring data back.  I was tasked with encrypting the data using AES and I was using the AESCBCEncrypt function on the List elements (up to 20k characters for each element) to bring it back before concatenating it on the middleware.  This almost worked.  Like 95% of the characters were being decrypted correctly but some text was coming back garbled.  I couldn't understand how this was happening.

Hello community,

I am receiving a HL7 message over TCP connection.

I have to set up  a process/operation to produce a daily file with this HL7 messages to be created in a directory using EnsLib.File.OutboundAdapter
and EnsLib.HL7.Operation.FileOperation. The file needs to have a header line added each time it is created and a footer .I did not find any standard class file under File Adapter which will create header/footer. 

Any suggestion will be greatly appreciated.

Thanks,

Jimmy Christian

Hi Developers,

I'm pleased to announce that in May InterSystems Spanish Developer Community celebrates its 1st Anniversary! 🎉

Our Spanish Community is growing: 300+ articles have been published this year and about 900 web users visit the site every month!

Hello!  I have basic web services application that c# clients connect to the cache web services.  Using the browser, the user enters in the following url.

http://localhost:57772/csp/user/%25SOAP.WebServiceInvoke.cls?CLS=Sample…

which runs a soap method called Add.   I am not sure how to add https  security to the web service calls.  I have reviewed documentation pertaining configuring SST/TTL configuration and other information.   Can somebody please help me out on what I need to do?   If I change the url  from http to https, the web service class will not work.

   Hi,

 I've started to use Task Schedule function in Caché. But I have two questions about it:

1. I want to run the task as an indepedent, technical user. What is the minimum resources for this user to successfully run the defined task.
2. I disabled the built in user _SYSTEM, as the Tightening Security for an Instance article suggest. But I see that built in task run in the name of _SYSTEM user. For example Switch Journal. How can this work, if the user disabled? Should I use another user for this tasks?

Thanks!

Hi All, 

So after finally getting cache to install (by enabling root user and disabling the gatekeeper) it tells me that it has started with one alert... that is "Private web server has not started after 5 seconds." - urgh!

Obviously i need access to the management portal to continue setup, I've done lots of googling but i cant find anything on this, does anyone have any ideas?

Many thanks, 

Dan

A More Industrial-Looking Global Storage Scheme

In the first article in this series, we looked at the entity–attribute–value (EAV) model in relational databases, and took a look at the pros and cons of storing those entities, attributes and values in tables. We learned that, despite the benefits of this approach in terms of flexibility, there are some real disadvantages, in particular a basic mismatch between the logical structure of the data and its physical storage, which causes various difficulties.

DeadJobAlert: Job 'X478915' for config item 'Business  Service' was marked as 'dead' under ghost Id 'sys:ZX478915_6117'

This is the error message I get, but can you advice how can I start debugging this? I look at the jobs and I just see "dead" I cant see any information on the message itself.

I would appreciate if you could advice on how to start debugging such a job. Events are also non-informative.

Hi,

Took one class room training where instructor told us to attend this 30 minutes training prior to the class but clicking the link https://learning.intersystems.com/enrol/index.php?id=632 shows the following message

Hi:

Sorry I can't find the correct documentation for this. It's very simple I think. 

I open up an XML reader class and correlate the XML to a message type. 

My XML will read something like 

This gets correlated into a message with the following property 

Property StatusLastChecked As %String(XMLPROJECTION = "element");

I can use the following to get the other properties out 

i.e.  docs.RelayedDocuments.GetAt(i).

I am trying to do package mapping in the %ALL NameSpace.

I create a new Package Mapping entry and select my database bu the "Package Name" combo box never populates the packages in this database so I cannot select it, see screenshot below, the "Package Name" list remains empty. There definately are packages in that database. Why is this happening? Did I miss a setting?

Hi everyone! I was using the InterSystems Native API for Python and following the documentation I tried to use this method (https://irisdocs.intersystems.com/irislatest/csp/docbook/Python-Native/irisnative.iris.html#irisnative.iris.getAPIVersion after a while I realize that this method doesn't exist. Looking at the object I can see the method: irisnative.iris.getClientVersion which doesn't exist in documentation (and probably does the same thing)

I'm using the irisnative-1.0.0-cp34-abi3-macosx_10_13_x86_64.macosx_10_14_x86_64.whl

How can we fix the documentation (or the class method name)?

Hello!
I’m happy to announce that we have published another course to online learning from the InterSystems Change Control catalog! The course is ICC310: CCR Tier 0 – Usage Basics.

To find all available CCR courses online, go to learning.intersystems.com and search for ICC or just click here.
 
ICC310: CCR Tier 0 – Usage Basics Description:
Learn the transitions and documentation fields for a BASE > TEST > LIVE CCR workflow. It is important to take this course even if you will primarily progress Tier 1 or Tier 2 CCRs because the documentation fields and transitions are common across all CCR Tiers.

I have a class method that accepts a global parameter but when I attempt to order this global, the global name is listed as undefined. I can execute $DATA(pGlobalName) successfully.

ClassMethod ExamineGlobal(pGlobalName As %Global)
 {
    set gStatus=$DATA(pGlobalName) ; returns 1 
    write "This is the global name: "_pGlobalName
    set gmin=$ORDER(pGlobalName("")) ; here pGlobalName is undefined
 }

In debug mode, data returns 1 for a valid global with no descendants. This is expected.

However, when I call $ORDER, it shows <UNDEFINED> for pGlobalName.

Hello All,

I am compiling a REST Operation to call our hospital Administration system, following tutorials around the REST API's etc. First time we have integrated like this so not much knowledge around our hospital - hoping someone on here can help.

I have been using the JSONStreamToObject Method which is working as i expected, apart from trying to get a specific item in the example JSON Response as follows:

{"test":"abc","name":[{"use":"usual","family":"Matest","given":["Mia"]}]}

I'm able to get family using  set pResponse.familyname = tProxy.name.GetAt(1).

 Requesting assistance on Intersystems Cache Managed Key Encryption.

We have configured the KMIP Server.

The KMIP server is an external HSM box. I was not able to find any info on Key Rotation and what type of encryption does it follow i.e. 1-tier approach or 2-tier approach.

Can someone please assist on the same?

Hi ObjectScript developers!

InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.

Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.

There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)

Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.

See the details below.

I can run the following commands from the AIX command line prompt without any problem

-bash-2.05b$ echo t
t
-bash-2.05b$ echo œ
œ

When I call from insider cache, I have problem.

USER>D $ZF(-1,"echo t")
t

USER>D $ZF(-1,"echo œ")

D $ZF(-1,"echo œ")
^
<TRANSLATE>

I am using cache 2017.2.  Can someone shed some light?

Thank you.
