Can you keep a secret?

If you are developing applications that use CSP or Zen, or potentially any of the other InterSystems web-related stuff that's built on top of CSP, then it's important to know how to keep one particular secret.

A central part of the CSP security architecture is a server-side session key. "Server-side" because its value should never be revealed to the client that is issuing the web requests. If it is revealed, a malicious client might be able to use it to bypass your security and make your server do things you don't want it to.

Stream Compression

Does anyone have insight into how the Stream Global Compression works in 2022? I'm particularly interested in the XDSb repository on the Edges. As I understand it anything new will be compressed. Is there a compression method that is used that can be utilized by other code? How are the retrievals aware that the contents are compressed in order to de-compress them?

We just upgrade from cache 2016.2 to IRIS 2020.1.1.

After this upgrade we cannot access to the portal web management, and dont give errors about that just this:

09/28/21-15:59:16:654 (20192) 1 [Utility.Event] Private web server has not started after 5 seconds.

Is this normal?

I followed the guide but dont talk nothing about that.

This is a normal problem when upgrading?

Thanks!!

Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit. I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

I am working on an ZAUTHENTICATE.mac to move us from local cache users to Delegated Authentication against LDAP.

I have created a user role within my instance of Ensemble that matches the AD Group that I will be assigning everyone in my group to. Is there a way to query the list of available Roles within Ensemble, and if one of my AD groups matches that role, set the role for that user?

How would I compare the AD Group against the Role listing?

Thanks

Scott

Hi,

I am getting the following error while logging in using LDAP authentication,

"An error occurred with the CSP application and has been logged to system error log (^ERRORS)". I've set the connection up and using Authentication Test was successful. I seem to be able to login as well but keep getting that error. If I allows unauthenticated access then the page works but changing it to LDAP is not working.

The LDAP account once created in Cache has U access to the resource related with the web application.

Hi folks!

Those who actively use unittests with ObjectScript know that they are methods of instance but not classmethods.

Sometimes this is not very convenient. What I do now if I face that some test method fails I COPY(!) this method somewhere else as classmethod and run/debug it.

Is there a handy way to call the particular unittest method in terminal? And what is more important, a handy way to debug the test method?

Why do we have unittest methods as instance methods?

This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

Get the sample data to the migration process

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

I have a requirement to update the Ensemble Host Settings Programmatically. Mainly the "AlertOnError,QueueCountAlert,QueueWaitAlert,InactivityTimeout" settings.

I used Ens_Config.Item (persistent) class to get the settings (list object) and then update it. But for some of the Business Host's, I dont see the above settings in the table, but present in Settings of that particular Host in Ensemble Management Portal. So my logic is not working.

Hello,

We would like to learn how would you approach this task.

We would need to check every day a set of folders which are outside our server (in fact we could see them as if they were "inside" the server), then we need to check for modified or created files in the last day, and move all the ones which match the criteria to just one folder in our server.

We have thought about doing the following:

1) Create a task to run it each day:

I am trying to find documentation on how Cache Studio locks a Routine/Class a developer is editing.

On the flip side, I am looking for documentation on how Atelier does the same.

Ultimately I am looking for the differences and what happens if both Studio and Atelier through different developers go after the same Routine/Class.

I am not asking for an answer (however that would be nice), I am looking for pointers to documentation.

I need some help with unescaping a value in TXA 2 of an MDM message that I am writing to a variable, to be used in a filename for a PF. Would I use the method Unescape(pData) if so how can I use it in a transform to set the variable? The reason I need to do this is I need to use the name as file name when writing the PDF to a directory. The escape characters and invalid for file names .

Hi, guys,

One of my clients was required by the hospital to name their webservice operation as Action_Subject, ie. Get_PatientInfo

When I define the web method as "Get_PatientInfo" as below,

/// MyApp.MyService
Class MyApp.MyService Extends %SOAP.WebService [ ProcedureBlock ]
{

/// Name of the WebService.
Parameter SERVICENAME = "MyService";

/// TODO: change this to actual SOAP namespace.
/// SOAP Namespace for the WebService
Parameter NAMESPACE = "http://tempuri.org";

How to develop in Logi

Today we will talk about InterSystems Reports. This is a BI system that provides you with tools to create static reports and export them to different file formats. We will see how it works using the DC Analytics public analytical sample as an example. In this article, we will examine how to familiarize yourself with the reports available in the repository, how to make a new report based on a ready-made data structure, and how to prepare a data structure from scratch.

Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: DevOps on June 2nd at 10:00 AM EDT!

In this InterSystems IRIS 2020.1 Tech Talk, we focus on DevOps. We'll talk about InterSystems System Alerting and Monitoring, which offers unified cluster monitoring in a single pane for all your InterSystems IRIS instances. It is built on Prometheus and Grafana, two of the most respected open source offerings available.

Next, we'll dive into the InterSystems Kubernetes Operator, a special controller for Kubernetes that streamlines InterSystems IRIS deployments and management. It's the easiest way to deploy an InterSystems IRIS cluster on-prem or in the Cloud, and we'll show how you can configure mirroring, ECP, sharding and compute nodes, and automate it all.

Finally, we'll discuss how to speed test InterSystems IRIS using the open source Ingestion Speed Test. This tool is available on InterSystems Open Exchange for your own testing and benchmarking.
