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.

Intersystems is all about name spaces. Each Name space can be mapped to one or more databases and vice versa. In my desktop with intersystems, Can i have DEV , TEST environments pointing to different name spaces at same point of time ? if i am right here, then the DEV environment is nothing but the namespace that we work on....Please let know

A few years ago InterSystems announced a tool to help Caché system managers on sites with a large number of Caché instances. It was called Enterprise Manager.

When I recently searched for information about it I didn't have much success.

We are in the process of setting enabling SSL on a soap web service exposed via InterSystems, but are running into trouble. We have installed our certificates on our webserver (Apache 2.4) and enabled SSL over the default port 57772. However, we now get an error when sending a soap message to the web service (it used to work over http). Specifically the CSP gateway refuses to route te emssage the soap web service:

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLS

Hi All,

    We are using the InterSystems cache 5.02
    We having 80 license unit but don't the reason 50 unit have been consumed (CSP unit)
    This happen because of this page ran frequently "/apps/docmatic/%CSP.SysConnection.cls"
    Can anyone explain why this page ran frequently and consume license?
    
Thanks,
Sansa.    
    

Hey all! I'd like to collect some feedback regarding searching for messages using the Message Viewer. I'd like to find out what things regarding the Message Viewer you all in the community have found difficult/confusing/poorly documented. This can of course include things that you don’t know how to do yet, but would like to learn about.

For an example, I’ve had issues searching through messages containing SDA for specific text fragments, because my searches always timeout or don’t return any matching messages. Other people that I work with have similar issues, but haven't found documentation th

Now that 2017.1 has been released, any indication when we can look forward to the next Field Test starting?

Update on 27-Apr-2017: the 2017.2 FT for Caché and Ensemble is now available via this page.

Update on 02-May-2017: announcement posted here.

I am looking for a way to deploy production changes (code and/or production configs) via script or some other systematic way other than the Ensemble/Deploy page in the Management Portal. My goal is to store these configurations in Subversion, then have a piece that can pull the XML from source control and deploy it to a given server. Is there some kind of script that I can run on a given server to perform this deployment? If so, I can tie it up with Subversion using another tool that I have access to.

If it helps, we are running Cache 2016.1 (HealthShare 15.01) on Red Hat Enterprise Linux 7.

Have you ever thought about leveraging IIS (Internet Information Services for Windows) to improve performance and security for your Caché web applications?  
Are you worried about the complexity of properly setting up IIS?

See the webinar Configuring a Web Server presented by @Kyle Baxter,  InterSystems Senior Support Specialist. Learn how to install IIS, set up it up to work with the CSP Gateway, and configure the CSP Gateway to talk to Caché.

If you have not subscribed to our Developer Community YouTube Channel yet, let's get started right now.  

Enjoy!

I'm asking this best-practices question on behalf of a customer.

They have a Caché-based application, and an Ensemble production deployed in front as an ESB to provide web service API access to the back end application. They're looking for a best practice approach for the scenario where the Caché back end is calling a third-party web service. Should that go through Ensemble too? It's sort of a philosophical design question/debate.

The current approach without going through Ensemble would be for Caché to import the service WSDL into proxy classes and invoke those directly from the application cod

InterSystems is pleased to announce the Field Test release of Caché and Ensemble 2017.2.0

• Improved XML VDoc performance in Ensemble
• Caché Nodejs now supports Nod

What is the correct way to write embedded SQL that will use a Like operator and local variable. Ex How can a sql query return the IDs of all rows where LastName has the substring "Doe"?

Set nameToFind="Doe". The below does not work.

&sql(Select ID from myTable where LastName like '%:nameToFind%')

Simple enough but this syntax is tricky!!

How can one delete a line in a stream? I do not see anything resembling a stream.DeleteLine method.

As we've all heard 2016.2 draws near and brings the removal of system methods with it.

There are two ways to make the code compatible with 2016.2:

• Replace system methods with new methods
• Replace system methods with macros

How to run cache programs(studio) from the command prompt?

Say you have a global in one database that you instead want to map from a different database. If you just create a global mapping to the new database, the existing global will become inaccessible because it still lives on the old database. The documentation notes this problem here but doesn't give details on how to fix it.

When you create the global mapping you need to explicitly move the existing global to the new database. This is possible using the merge command along with extended global reference. The environment syntax lets you reference a global in a specific namespace, directory, or rem

Hi,

I am wondering if there is a way I can change the GUID of an instance. The use case is that I am restoring from a backup on an alternate host and start the instance there. However, the restored instance ends up with same GUID as that of source. Is there a way I can tell this newly restored instance to use a different GUID?

Thanks,

Hi I'm hoping the community will once more help me out with a question!

Right I have a production that takes an attachment from an email and processes it, sending out a hl7 message at the end. This works ok.

Now I just need to take the email and send it back out to a 'backup' email address, basically giving
a) A backup incase there is a problem with the email or something else further down the line.
b) A log of the emails receieved.

So I thought the best thing to do is have an operation with an email adapter and to send that my message.

That gave me some code that's basically like this.

 How to create an instance for the production class?

I wanted to run the cache programming from the windows command line promt and also with linux commands. Please let me know the procedure. 

Hi Everybody,

I'm trying to restore database to a 2016.2.2.853 caché version but i've some problems ...

Into my backup file, i've 6 namespaces. After use the Do ^DBREST and configure all namespace into the portal, I can only reach 2 of 6.

when I write zn "blabla" into the terminal, i've got this error message :

ZN "blabla"
^
<DIRECTORY> *r:\data\blabla

Of course, Database and namespace are correctly define.

I've try this on a previous version of caché (2015.2.2.811) and it's working fine.
So, do you already got this kind of issue with your caché server ?

Tanks a lot for your help!

With the recent release of Caché and Ensemble 2017.1, InterSystems customers can now create configurations where the data-at-rest cryptographic library used is compliant with FIPS 140-2.

Caché and Ensemble now provides you with the option to enable FIPS mode on RedHat 6.6, 7.1 on x86-64. This means is, that InterSystems products will no longer use the supplied crypto libraries that come with the kit, but will use the FIPS validated libraries provided by the Operating Systems vendor.

To configure your system, RedHat must operating in FIPS mode. This can be done be following the steps provided by

The last version of Caché, Ensemble released for VSI OpenVMS is 2017.1. Unlike HP OpenVMS (Alpha and Itanium), VSI OpenVMS on Itanium continues to be supported. This means that critical corrections or changes required to support customer’s hardware purchases will all be based on 2017.1 or earlier versions.

I've been creating some posts with embedded images, and some of the images seem to stop resolving after a period of time.  I've resaved them, and that has helped temporarily, but I just checked and one of the images is now not resolving again.  Is there a limit to the number of images on a post, or should I be using a specific filename pattern?

THanks

Hi ,

We are trying to import file using %installer . But we are getting error.

CODE:

Include %occInclude Class User.InsClass { // You can see generated method in zsetup+1^App.Installer.1 XData Install [ XMLNamespace = INSTALLER ] { Flags="ck" IgnoreErrors="0"/> } // Entry point method, you need to call // At class compile time it generate Caché ObjectScript code from the manifest // After that you can run this installer from a terminal: // Set pVars("Namespace")="NewNamespace" // Set pVars("SourceDir")="C:\temp\distr\" // Do ##class(User.InsClass).setup(.pVars) ClassMethod setu

Prompted by this post about accessing a global at its original location after you have changed a mapping, here's a tip about one specific dropdown in Portal that's sometimes useful.

I heed to his a callback method after all REST call. I have already found a method to call before REST call, but after eludes me. Here's the code:

Class Test.REST Extends %CSP.REST
{

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>

<Route Url="/:classname" Method="GET" Call="TEST" Cors="true"/>

</Routes>
}

/// This method Gets called prior to dispatch of the request. Put any common code here
/// that you want to be executed for EVERY request. If pContinue is set to 0, the
/// request will NOT be dispatched according to the UrlMap. If this case 

Please let me know in Intersystems Ensemble Prodn, where the configuration setting changes gets stored ?
