Hi guys,

 

Couple days ago, a customer approached me with the wish to enhance their existing legacy application, that uses SOAP (Web)Services so it shares the same authorization with their new application API based on REST. As their new application uses OAuth2, the challenge was clear; how to pass access token with SOAP request to the server.

After spending some time on Google, it turned out, that one of possible ways of doing so was adding an extra header element to the SOAP envelope and then making sure the WebService implementation does what is needed to validate the access token.

We had our first meetup of the Prague Meetup for InterSystems Data Platform last Thursday!

As it was our first such venue, the attendance was not large, but we believe it was a good start. Those who attended could learn about new features that InterSystems IRIS brings to our partners and customers as well as listen to a presentation discussing what it takes to migrate from Caché or Ensemble to InterSystems IRIS and eventually containerizing their applications.

We all enjoyed excellent assortment of various tea species, accompanied by vegetarian food. (so you know what you can expect next time :) )

Attached you find a picture taken at the meetup.

Looking forward to see you next time and perhaps in a bigger group!

I was approached recently by and end use who wanted to perform analysis of their databases and see how they could save some space by picking data good for deletion without harming the application. As part of investigation, they wanted to know sizes of globals within datasets. This can be achieved by various means but all of them provide data in text form only.

I thought I might be a good tool for database administrators in general - to see global sizes in a graphical way.

Is there an API that would list classes within a given package? I can't find any. I do have a workaround that uses class index, but this query lists all classes available in the namespace and I have to filter those I want. But this is just unnecessary overhead.

If anyone has spotted such API, please let me know.

TIA!

Dan

As many of you, our partners, are more widely using modern UI frameworks to create client front-end, you may have encountered a question, "So how do I secure my data when I just finished developing all new fancy browser based client experience?"

The answer is easy. Use a standard, proven OAuth2 and OpenID!

"OK, but how can I do it? I have never done it before."

No problem, just have a look here, if your client is Angular (not AngularJS) based, there is a demo project available for you to review and get inspired!

The demo presents a simple Angular (and typescript) application with user login and public/private data REST based retrieval from a server. Please bear in mind that I'm not an angular expert, so my coding might not be the best quality, but the demo is functional (at least on my machine, sigh!)

Hope you'll find it useful!

Hello,

I have a series of data organized by time (year and month) so I can use a time dimension to drill down data. So far so good.

However, I need to display the data not by calendar years and months but rather by seasons. The season has 12 calendar months but starts in September. So I'd like to see the data from September / Year N to August / Year N+1 using the same hierarchy as normal time dimension.

Has anyone done something similar?

Obviously, the season can start by any month, not only September :)

 

TIA!

It's almost a year since I have published a series of articles explaining how to configure Cache instance as a client / resource server / authorization server. By that time, the implementation of OAuth 2.0 was still a pre-release software.

With the advent of Cache version 2017.1 a lot has changed. OAuth 2.0 implementation is fully completed and supported. Numerous new features were added (e.g. dynamic client registration)  - see release notes here for full details - and configuration pages have been redesigned to a great extent as well

Created by Daniel Kutac, Sales Engineer, InterSystems

 

Part 3. Appendix

InterSystems IRIS OAUTH classes explained

In the previous part of our series we have learned about configuring InterSystems IRIS to act as an OAUTH client as well as authorization and authentication server (by means of OpenID Connect). In this final part of our series we are going to describe classes implementing InterSystems IRIS OAuth 2.0 framework. We will also discuss use cases for selected methods of API classes.

The API classes implementing OAuth 2.0 can be separated into three different groups according to their purpose. All classes are implemented in %SYS namespace. Some of them are public (via % package), some not and should not be called by developers directly.

Recently, a partner company started to develop an Angular client for their Cache application. Together, we decided to leverage the power of Caché dynamic objects to exchange JSON encoded data between client and server parts. However, we realized that currently there is a gap in Cache JSON implementation that prevents simple use of traditional registered and persistent classes to exposed their data with the same ease as with XML. I wrote a small JSON adapter, that does the job and bridgers the gap. It's purpose is simple expose data described by a regular Cache class in a one-to-one fashion to a %DynamicObject. On the other hand, when a serialized JSON data comes in, it can be easily deserialized into dynamic object and subsequently bound to regular class by the newly created adapter.
