IRIS 2010.1 brought us a new feature: %Net.WebSocket.Client

As a continuation of my series of WS Clients I just couldn't resist to try it.
Well, this is the result and it was rather simple in the end.

• After I succeeded in my personal fight against Windows Firewall ;-)

You basically need to prepare 3 classes:

• Credentials for User, PW, SSL
• an Event Listener
• the Client (Could be a .MAC routine as well)

The example uses the WSS.EchoServer (a derivate from former SAMPLES in Caché).
The default assumption is to have Client and Server on the same system & namespace.

In Caché you had an example of a WebSocket Server in namespace SAMPLES
With IRIS the samples are gone and require additional installation effort.

So I refurbished the code with some useful additions:

• independent of namespace
• timeout control from client
• readable communication log

This contains 2 classes:

• rcc.EchoServer.cls
• rcc.WSScsp.cls for testing. Called from Browser by (http://localhost:52773/csp/user/rcc.WSScsp.cls)

The server is essential for the 'native' WebSocket Client Demo

Hi-

I am trying to create a named filter in analyzer that filters for encounters that happened yesterday.

The UI only allows me to select the NOW member, and not NOW-1

Where is this named filter stored, and can I edit the MDX expression to add -1 to the MDX?

Is it possible to integrate Microsoft Dynamics with Ensemble?

Does anyone have experience in creating a Business Routing Rule using Exists function?

I've used the comma delimited 'In' function, but I would like more manageability. Entering and remove items from a look up table would be much easier to manage then changing the comma delimited string.

Messages go to error state.

Any help would be appreciated.

This is my first post, so if I am doing anything wrong please let me know.

A recent discussion made me aware that the documentation on DataType classes is excellent.
http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…
I just miss the visualization of the methods for Data Format Conversions.

LogicalToDisplay() / DisplayToLogical()
LogicalToOdbc()    / OdbcToLogical()
LogicalToStorage() / StorageToLogical()
LogicalToXSD()     / XSDToLogical()
Graphic makes it much easier to understand for anyone beginning with Caché objects.

Hi Community!

Please welcome the new video on InterSystems Developers YouTube, recorded by @Patrick Jamieson:

⏯ InterSystems API Management and FHIR

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.

Hi Developers!

In March 2020 we improved again developers community engine and introduced the following new features:

• PDF export and print option for every post;
• more than one accepted answer;
• filter mentioning for silent members;
• bug fixes and minor enhancements.

See the details below.

The attached code package provides a simple implementation of a web service client that utilizes the USPS Shipping API to normalize  an address.

This code requires the developer to obtain a USPS Shipping API user ID which can be obtained from the USPS shipping API website.  The assigned User Id can either be passed into the web service call as a parameter or can be coded as a parameter into the Request object.

Dear HealthShare Customer:

This post is part of the HealthShare HS2020-04 Alert communications process.

GA releases are now published for the 2020.1 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

A full set of kits and containers for these products are available from the WRC Software Distribution site, including community editions of InterSystems IRIS and IRIS for Health.

The build number for these releases is 2020.1.0.215.0.

InterSystems IRIS Data Platform 2020.1  makes it even easier to develop and deploy real-time, machine learning-enabled applications that bridge data and application silos.

Hi,

I'm using Operating System authentication and I need to give permission on Healthshare to allow a user to run only this two commands 

##Class(Backup.General).ExternalFreeze()

and

##Class(Backup.General).ExternalThaw()

This user is gonna be use to backup only.

There are any role on HealthShare for this?

Hi, 

I'm having a problem when I'm attempting to freeze the instance.

I have a pre-script and post-script to freeze and unfreeze the instance, but when the script execute: 

 csession INSTANCE_NAME -U '%SYS' "##Class(Backup.General).ExternalFreeze(\"$SNAPLOG\",,,,,,1800)"

 It's give me this error and fails the freeze: 

Backup.General.ExternalFreeze: Failed, Unable to switch local journal file, Error: -99,ERROR #1142: Error switching journal file: 0
vi

At cconsole.

InterSystems has corrected a defect that can result in data integrity issues on systems using mirroring.

This defect affects:

• All currently released versions of InterSystems IRIS and IRIS for Health, except 2020.1
• Caché and Ensemble versions beginning with 2011.1.1
• All HealthShare products based on the above Data Platforms versions

This defect is more likely to be encountered in IRIS and IRIS for Health 2019.4. It is highly unlikely to have occurred on deployed systems running any other version.

Hi Community!

The new video from Global Summit 2019 is already on InterSystems Developers YouTube:

⏯ A Skeptics Guide to Containers

The intersystems documentation gives the same description for both <MAXSTRING> and <NETWORK DATA UPDATE FAILED - MAXSTRING>. I suspect that the description for <MAXSTRING> is correct and the description for <NETWORK DATA UPDATE FAILED - MAXSTRING> was an accident. I would like to know what situation triggers the <NETWORK DATA UPDATE FAILED - MAXSTRING> error.

I want to create a CSP page that returns a pdf. The pdf is identified by a pdftoken parameter.

My goal is to validate the token and return the pdf (ContentType=”application/pdf”) if the token is good and return a text error message "Bad Token" (ContentType=”text/plain”) if the token is missing or bad.

My issue seems to be associated with ContentType. I can define one ContentType that works for the pdf or the error message. I am unable to change the ContentType.

Any assistance is appreciated.

ClassMethod OnPage() As %Status { set pdfToken=$get(%request.

Hello everyone!

I have an abstract class representing the possible inputs for an Enum field, in the following way: 

 Class system.dto.sector.SectorStatusEnum  [ Abstract ]
{

 Parameter Active = 1;

 Parameter Inactive = 2;

 Parameter Production = 3;

 Parameter Upkeep = 4;

 }

I need to create a persistent class referencing the abstract class in the status field, so that the result of the operation is the same as the example:

 Class datas.

Hello; we are scanning 835 files, and need to validate segment types (such as ISA, ST, IEA, etc.)  before we give the file the "OK".  I see segment types in the management portal under Ensemble / Interoperate / ASC X12 / ASC X12 Schema Structures.  Are these segment types stored in an IS table anywhere?

Aside from EnsLib_EDI_X12.Document, are there any other tables that describe, or support, document segment types?

Thanks,

Laura

Hi-

I have a class that specifies that streams should be stored in SSA.DocumentCacheS, however, they are getting stored in CacheStream instead.

How can I get streams to properly store in SSA.DocumentCacheS?

Here's the section from my storage definition that shows the StreamLocation

<DataLocation>^SSA.DocumentCacheD</DataLocation>
<DefaultData>DocumentCacheDefaultData</DefaultData>
<IdLocation>^SSA.DocumentCacheD</IdLocation>
<IndexLocation>^SSA.DocumentCacheI</IndexLocation>
<StreamLocation>^SSA.DocumentCacheS</StreamLocation>
<Type>%Storage.

Hi Developers!

Hi Caché-Developers!

My Caché Version: 2014.1 and the CSP-Gateway Version ( + Apache) also. I can't upgrade now. 

I want create a Web-Socket for my Chat  like in that Tutorial:

https://community.intersystems.com/post/tutorial-websockets

And there's my problem. When I set SharedConnection like:

set ..SharedConnection = 1

I get on init connection with the server that message:

First i think everything is okay but here i also didn't get the Messages on init from Server-Side:

When I now send a message to the WebSocket, I got following error:

I know that collection is instance of %AbstractList.

But what about $listbuild? Does it possible to detect that given variable is instance of $lb?
