InterSystems Caché is a multi-model DBMS and application server
WebSockets as a communication technology wins increasing importance.
In the SAMPLES namespace, you find a nice example for running a WebSocket Server.
There is also a useful example for a Browser Client. JavaScript does most of the work.
My point is:
How to consume the output of a WebSocket Server in your application?
Hi,
somehow my installation on win10 canceled during finish. "Installation of Caché finished" showed up for 20 minutes and canceled with an error I didn't saved.
Every file and service was installed but never registered as successfull installation. Now I try to reinstall it but the installer shows me everytime "Another installation is already in progress. Please finish the second installation first".
The unfinished installation is broken. I can't startup Caché from launcher. So I deleted everything in c:/intersystems
Things I already tried:
Hello,
I am having a problem with SQL Select, the command in portal is OK, show all items, but when I use a CacheDataAdapter in VB .NET show the message 'Incorrect list format 0>=0'. What could be this message? Because is the same SQL command.
Best Regards.
Here's a sample code to display JSON or dynamic object.
It shows how to iterate over object, get property values and their paths.
I want to insert multiple records in the table using below queries, but it gives an error.

Hi,
I am facing issue during LDAP lookup like whenever I used product group parameter in AD explorer to search data from application I am getting empty result. If I set product group parameter as null then based on distinguished name result is generated in application. So if anyone knows about how LDAP works and how parameters are set in AD explorer then please let me know.
Thanks in advance.
I'm trying to sign an xml but this is showing an Id attribute in the Signature tag and the xmlns attribute is not appearing.
This is the xml generated:
I can't do it from the Management portal due. I get a message that DDL is not enabled. So how else do I drop the table?
In this article, we will explore the development of an IRIS client for consuming RESTful API services that have been developed to the OData API standard.
We will be exploring a number of built-in IRIS libraries for making HTTP requests, reading and writing to JSON payloads, and seeing how we can use them in combination to build a generic client adaptor for OData. We will also explore the new JSON adapter for deserializing JSON into persistent objects.
Hi, everyone!
I want to share a personal project that started with a simple request at work:
Is it's possible to know how many Caché licenses we are using?
Reading other articles here in the community, I found this excellent article by David Loveluck
The %Net.SSH.Session class lets you connect to servers using SSH. It's most commonly used with SFTP, especially in the FTP inbound and outbound adaptors.
In this article, I'm going to give a quick example of how to connect to an SSH server using the class, describe your options for authenticating, and how to debug when things go wrong.
Here's an example of making the connection:
Howdy, Developer Community!
Here’s a fun little formatting problem you may run into when trying to use the RSAEncrypt method of %SYSTEM.Encryption (also useable as $System.Encryption.RSAEncrypt()!), which is documented here:
This is the first in a pair of articles on SQL indices.
I wanted to write it as a comment to article of @Evgeny Shvarov . But it happens to be so long, so, decided to post it separately.
I would like to add a bit of clarification about how docker uses disk space and how to clean it. I use macOS, so, everything below, is mostly for macOS, but docker commands suit for any platform.
My database service is on the cloud server, and I access it on the company intranet. When I user the %request.CgiEnvs to get "REMOTE_ADDR", but what I have been getting is the company's external address. I can't get my IP address in the LAN.
For example, my computer IP address is 192.168.11.11, and my company's external public network address is 214.17.17. I can only get 214.17.17 by using %request.CgiEnvs("REMOTE_ADDR"), but not 192.168.11.11.
I only want to get 192.168.11.11.
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.
Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.
Hi,
I want to know if anyone tried calling a CDS service from Healthshare/Ensemble. Will that be similar to any other API or is there anything different in constructing CDS Hooks and consuming the CDS Cards received in the response?
If a picture is worth a thousand words, what's a video worth? Certainly more than typing a post.

A good writer is supposed to draw you in with the title and bury the answer somewhere in the article. I suppose this makes me a bad writer – don’t think less of me, my whole feeling of self-worth comes from the opinions of internet strangers!
Can anyone clarify to me about the differences between these two classes?
People in this topic https://community.intersystems.com/post/using-class-queries-sqlstatement-versus-libraryresultset stated that %SQL.Statement (I am assuming they mean to talk about %SQL.StatementResult) is newer than %Library.ResultSet. But I don't really know what are the advantages of %SQL.Statement over %Library.ResultSet as the people in the topic somehow didn't mention them.
Currently, when we want to write data to a file that will be viewed in Excel, we parse the data in tab deliminated format to the file and name it with .xls at the end. That is sent to end users via email. They get a warning that the data is not formatted properly (it's not really an Excel file after all) but it does display somewhat correctly as the tabs are understood (this does not work if we deliminated with commas however).
Hello,
I am wondering the best way to disable a user account using this class in Cache (Security.Users).
https://cedocs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls
Example User Account = jhipp
Currently is Enabled
I know that we can use the auto-generated EnabledGetStored method, for example:
%SYS> w ##class(Security.Users).EnabledGetStored("jhipp")

Hello everybody,
My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.
The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:
Hi,
I have a large XML zen report file that I want to convert to a CSV, what is the most efficient way to do it.
XML file:
<Details> <Col1> aa1 </Col1> <Col2> bb1</Col2> <Col3> cc1 </Col3> </Details> <Details> <Col1> aa2 </Col1> <Col2> bb2</Col2> <Col3> cc3 </Col3> </Details>
Expected Output:
Col1,Col2,col3 aa1,bb1,bb1 aa2,bb2,bb2
