Hello,

I'm hoping to get some feedback on the OAuth process flow for Payer-to-Payer authorization.  It doesn't seem that "Authorization Code Flow" is needed as there will not be a need for a login.  I am leaning towards recommending "Client Credentials Flow", but wanted to get some community feedback before making a decision. I prefer to follow what the standard will be if possible.  What would you recommend?  Thank you in advance for your input.

I am facing below error after force stop the instance.

method Export(savertn As %Boolean = 0) [ Language = objectscript ]

I am looking to export table to a text file in a programmatic way. I am not familiar with this class and how to invoke a "savertn" as input here.

Essentially I would like to Export Table (SELECT * FROM Table) and save it as a text file locally on Linux server. Is there any examples out there of that? Perhaps I need to save the query output to a global and then pass that input to the export?

Hey Developers,

The InterSystems Analytics programming contest is over. Thank you all for participating in our coding competition!

So it's time to announce the winners! 

A storm of applause goes to these developers and their applications:

Some of you might not be aware of this "Known Issue/Limitation" when defining a BPL-based Business Process.

And those who are not might have encountered this (somewhat "unpleasant" error):

This post provides useful links and an overview of best practice configuration for low latency storage IO by creating LVM Physical Extent (PE) stripes for database disks on InterSystems Data Platforms; InterSystems IRIS, Caché, and Ensemble.

Consistent low latency storage is key to getting the best database application performance. For applications running on Linux, Logical Volume Manager (LVM) is often used for database disks, for example, because of the ability to grow volumes and filesystems or create snapshots for online backups. For database applications, the parallelism of writes using L

⏯ iKnow: Open Source NLP in InterSystems IRIS

This article suggests to you some patterns to create REST API applications using IRIS.

Note: source code in https://github.com/yurimarx/movie

Class Pattern to the REST Application

To begin, see my suggestion for classes needed to create IRIS API applications:

• IRISRESTApplication: CSP.REST class that will be the central controller for all REST requests and responses processed by the business services.
• BusinessService: class with a business topic implementation. It can use one or more Persistent Domain Classes to persist and query data required by the business topic requirements.
• Persi

I'm launching a bug bounty for a bug with which I've been struggling for the last 4 years. Have tried to resolve it many times, but no  dice - can't track it down.

Here's the issue.

To claim this bounty you need to:

1. Create a pull request with the code to fix the issue outlined here.
2. In the pull request OR in the issue OR in the commit message describe what's the reason for this bug and how your change fixes it.

First come first serve. Bounty would be paid only ONCE for a first working solution.

I really love documentaries! Last weekend I was watching a Netflix documentary called This is Pop, because it was Analytics Contest time and I thought: Why not creating a pop song analytics with InterSystems Iris?

The first challenge was the database. I found on Data World project a CSV file with the Billboard hot 100 songs from 2000 to 2018, created by "Michael Tauberg" @typhon, that fits perfectly.

I was talking to @Henrique Dias and he gave me the idea of using Microsoft Power BI for good looking report with charts.

Which genres were most popular between 2000 and 2018?

Which artists had more so

Have you heard about some restrictions in cookies for tracking visitors to your sites?

One of our clients asked me about how to know really count of visitors.

Their site works on WordPress framework, hosted on classical NAMP hosting.

They can see some statistics from Yandex Metrika conter, but we was not sure about full coverage.

We gave him the AWStats, it takes data from Apache log files on hosting.

But there were no filter of robots and hearbeat systems such as UptimeRobot or Search Engines indexing robots.

After that we decided to get data in IRIS BI for two reasons:

I regret getting a late start in the InterSystems Analytics contest. I had tried a couple of times before to use Analytics, but I had not gotten too far. I have been recording financial transactions in Excel workbook ever since I had to retire Microsoft Money. Since my iris-for-money was not fully functional, I created a worksheet per account I was tracking. I had developed a CSP page in iris-for-money to import transactions by reading a CSV file. I realized this process requires escaping many characters that can cause the process to fail.

One week ago I realized I had just two days left t

Hi Developers!

We had a set of technology bonuses for the InterSystems IRIS Analytics contest.

And here is how projects collected it:

Previously I have already tried to play with Google Data Studio when I connected it to InterSystems FHIRaaS. It has quite a nice UI, with a few chart types available out of the box, it can be quite easily connected to some plain tables (stored as CSV or JSON, for instance), and gives the ability to build quite flexible analytics over it. So, I have decided to implement a new connector to InterSystems Analytics (DeepSee), with the ability to select a cube and do some queries on it.

The OKR methodology (Objectives and Key Results or Objectives and Key Results) is used by the largest companies in the world (such as Google, Netflix, Spotify, BMW, Linkedin, etc.) for agile performance management. It was created in the 1970s by Andrew Grove, president of Intel, and introduced to the general public in his famous book “High Output Management”.

Around 1998 John Doerr, one of the world's top venture capitalists, after coming into contact with Intel's OKR, introduced the model to Larry Page and Sergey Brin, who started a small company called Google.

Hi everyone - In IRIS we would like to arrange the access of two users in such a way that each has access to exactly one (his) database only. Which resource does this (%DB_%DEFAULT allows each of the two users access to both databases). If you create new resources (%DB_Database1 and %DB_Database2) and then add them to individual roles (each for the user to), the access for the users, for example, via a REST client does not give the desired separation (instead once Ok, other database 401 Unauthorized both OK). Is there something special to consider or a special resource that could do this or ..

Hello everyone

I am new to cache. In an interview i was asked how to optimize a sql query.

I just said I will create index on conditions which are present in where clause. But as per interviewer I should check How query plan is getting executed. This will help in optimizing Sql queries. 

I want to know what will be the answer for how to optimize SQL query in cache. 

Thanks in advance!!

Hello Everyone

I am new to cache. I know there are 2 types of methods in cache. One is Instance method (Which can be call through object creation of particular class) and other is Class methods (which can be call through ##Class(MyPackage.Car).CarModels()). 

I want to know the difference when to create a instance method vs when to create a class methods.

Thanks in advance!!.

How Can I Do It (rebuild index) using ObjectScript?

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 any platform.
