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.

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!

Question Raouf Besbes · Jan 12, 2018

Hello

I'm in the process of creating a TestClass which simulate a HTTP POST call to REST-based web services and while I am having success, I'm struggling on how to parse out the results to a JSON format

Here is down the code part which concerns parsing the HttpResponse.Data variable into JSON :

s httprequest=##class(%Net.HttpRequest).%New() 
s httprequest.Server="http://127.0.0.1"
s httprequest.Port="57772"
s httprequest.Https = 0
s httprequest.ContentType="application/json"
s httprequest.Authorization = "Basic X1N5c3RlbTpTWVM="
d httprequest.EntityBody.Write(json)
s sc = httprequest.

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,

<ZSOAP>zInvokeClient+205^%SOAP.

Hi Guys,
Can you please guide me to get rid of this issue. Please find the image files with this post.

Please let me know, before we are developing an API what are all the setup/Configuration(Apache/web server) need to do in my machine. 

If any lead would be appreciated. 

I don't know, in XMLNamespace parameter which URL need to use.  

.

Thanks,

Arun Kumar Durairaj.

In short, I wanted to react on CPUusage warnings and alerts with my own actions. It seemed that it was possible in my Caché version (2015.1): 
http://docs.intersystems.com/cache201513/csp/docbook/DocBook.UI.Page.cl…

But all my attempts silently failed. Callback code was as simple as possible: 

Class %z.Monitor.Health Extends SYS.Monitor.Health.AbstractCallback
{
/// This method is called for every Health Monitor sensor reading.<br>
///.

Question Seth Rothenberg · Nov 29, 2017

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel, 

which would improve our detecting of issues.

Has anyone done something like this?

I see that the  class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself.   Instead, it appears 

to return a handle into the tunnel.     It will work a bit differently.

Question Rubens Silva · Nov 9, 2017

Hello.
We're about to implement an application that could use WebSockets intensely so before we head to that direction we need to figure out about how some few things work. That being said, anyone care to give me some enlightenment?

  • What's the criteria for a new session to be created when using WebSockets?
  • What's the factor for calculating how many licenses to would be used when SharedConnection  is enabled for WebSockets?
  • Is there a way to use session in a way that it would optimize the license usage for a single user?

Question Thomas Li · Sep 26, 2017

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports.  We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down.  We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page.  I am new to Cache so any help would be greatly appreciated.

Also, is there an easier solution to this print all problem?

1. Scope and Objective:

Recently we supported a few NHS cases that required TIE (Trust Integration Engine) integration with the PKB service.   Hence this article is meant to be a 10-minute quick guide to describe a demo solution (simple configurations and end-2-end implementation steps) for Health Connect (Ensemble) Integration with PKB (Patient-Knows-Best) service.

MonCaché — MongoDB API implementation based on InterSystems Caché

Disclaimer: This article reflects author's private opinion and has no relation to the official position of InterSystems.

IDEA

The idea of the project is to implement basic MongoDB (v2.4.9) API features for searching, saving, updating and deleting documents in a way that will allow the use of InterSystems Caché instead of MongoDB without changing the code on the client side.

MOTIVATION

Perhaps, if we take an interface based on MongoDB and use InterSystems Caché for data storage, we may see a performance boost.

Question Alexey Maslov · Aug 21, 2017

Hello everybody,

We have a piece of Caché software which calls an external utility using $zf(-1,command). It works fine under Linux, but under Windows an external process occasionally hangs (due to some internal problems out of the scope here) and need to be killed programmatically. Having PID, it's easy to kill a process. If a Caché process is called with JOB command, the caller can easily get its PID from $zchild, but alas $zf(-1) does not seem to return the similar info. Is it possible to get it somehow?

Question Raghu Kodumuri · May 8, 2017

Hello,

I am wondering if there any mechanism available in the Healhtshare where send a request from the service to the operation without storing the Data on CACHE.DAT?

My company going to receive ADT's and CCDA's from an external source (Hospital), The incoming data will have two kinds of patients, our patients, and not our patients.  We do not want to keep the data on our servers of those patients that do not belongs to our company due to HIPPA complaint

Looking forward to hearing great ideas from this community.

Thank you

Raghu
