Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.

Hello Cache Developers:  I was curious if anyone has ever created a TWAIN interface to their Cache Application?   I am new to TWAIN and hence the reason for this question.  From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application.   I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table.    Any input, sample code, or suggestions is appreciat

I am working on my first REST operation concept and had a question about the Property Parameters. If I put a value in CAPTION, does that mean that when I use it in my call that it will come out in the URL?

For example...

Property enumerationType As %String(CAPTION = "enumeration_type");

Then in my operation...

Set tURL=..Adapter.URL_"?q="_pRequest.enumerationType

so when it builds the URL it looks like...

Hi,

We are trying to write an external backup application to backup Cache Database. After going through the Cache DB documentation, we have found that in Backup.General class there are methods for creating snapshot (Freeze/Thaw) which is required during backup. Are there REST APIs for the same?


Also we have the option of selecting individual DB instances in the management portal.  What are the methods/APIs of getting the DB list, so that user can select individual DB instances in an external backup application ? Do we have the methods/APIs to freeze/thaw the individual DB instances ?

Thanks!

Hi dev community,

I am currently  working on an interface that needs to communicate to a SOAP/ITK endpoint.

I am using the EnsLib.ITK.AdapterKit.Operation.SOAPOperation to interface with an ITK 
service, but it is proving to be more complex than originally expected to set up the web client 
against that particular end-point since I haven't been provided with a WSDL from ITK service side as 
the vendor state they are following the ITK standard and no WSDLs are needed.

I have set up an EnsLib.ITK.AdapterKit.Operation.SOAPOperation within Health Share production and

Hi all.

I want to insert my dataframe into InterSystems IRIS. So, I tried to do this:

df = spark.read.load("/home/imported-openssh-key/zeppelin-0.8.0-bin-all/bin/resultData3/DF.json", format="json")
df.write.format("com.intersystems.spark").\
option("url", "IRIS://localhost:51773/DEDUPL").\
option("user", "********").option("password", "********").\
option("dbtable", "try.test1").save()

And got this error:

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL -  api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

do httpRequest.InsertParam("EDD",..Data.Verify.EDD)
do httpRequest.InsertParam("ETHNICITY",..Data.Verify.Ethnicity)

where httpRequest is an object of %Net.HttpRequest class

Question is how will these

SQL gateway.

There is a basic problem with sql gateway,

while building the proxy methods, with:

##class(%Net.Remote.Gateway).%ExpressImport(class, port, host, 0, classObj)
it causes error messages as something in the class is not correct,

while this class passed OK all Visual Studio of C#

and same class working OK under the %Activate Assembly link

I think there is also problem  with overload methods (same methods names).

Regards,

Emanuel

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format

Hi all. Today we are going to use k-means algorithm on the Iris Dataset.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, python 3.6.5.

Introduction

K-Means is one of the simplest unsupervised learning algorithms that solves the clustering problem. It groups all the objects in such a way that objects in the same group (group is a cluster) are more similar (in some sense) to each other than to those in other groups. For example, assume you have an image with a red ball on the green grass. K-Means will split all pixels into two clusters. The first cluster will contain t

Hi!

It is often necessary to run some external command such as a python program or a shell script from inside Caché/Ensemble. There are three ways of doing this:

  • $ZF(-1) - Runs the command and waits for it to finish.  
  • $ZF(-2) - Runs the command and don't wait for it to finish.
  • Using CPIPE device - Runs the command and opens a device for you to read its output or (exclusive or here!) write to its input.

$ZF(-1) is normally more interesting because it allows you to recover the return code of the program you are calling. If that is important to you, that is the way to go. But while the

Question David Crawford · Feb 20, 2018

I'm experimenting with sending large amounts of data in a POST payload to be stored as a stream. However I've noticed that no matter how many characters are in the message, Cache only gets about 32k of them, cutting off the rest. Conversely as expected it can only send about 32k worth of characters in a payload.

Before I get creative, is there a REST message size limit that can be changed? Or is there something else going on here?

Thank you!

Hi all,

I have started using the UPS in my application for shipment and cancellation.

I have the WSDL from the UPS.

I have imported the WSDL via Studio->Tools->addins and finish the process to get the Package implemeted in my studio.

Now the SOAP method contains a URL which is for their live system so i manually changed the URL with their Testing URL.

They are also providing the sample shipment numbers which we can use to test the cancellation process.

I am trying that shipment number to void(cancel) the shipment by call the method.

And i am facing the error as below,
