#InterSystems IRIS

Over the past year or so, my team (Application Services at InterSystems - tasked with building and maintaining many of our internal applications, and providing tools and best practices for other departmental applications) has embarked on a journey toward building Angular/REST-based user interfaces to existing applications originally built using CSP and/or Zen. This has presented an interesting challenge that may be familiar to many of you - building out new REST APIs to existing data models and business logic.

Hello everyone

I am new to cache. I want to know how we can perform database tuning.

Thanks in advance!!

Hello everyone. I am hoping someone here can help me get my local instance running. I have set up these local instances in the past (pre IRIS) and never had much trouble, but I have spent so much time the last couple days trying to work through this problem and am out of ideas. It has been years since I have set up a local instance so this could be something I am doing wrong, but I am open to any suggestions. I am trying to setup a Vista database like I have in the past by creating a new database and namespace named VISTA, have created a folder with the FOIA .

Just wanted to thank InterSystems for sponsoring this year's HACKMIT!

⏯ Getting Up to Speed on InterSystems API Manager

I have an ObjectScript class with a Log property of type %Stream.GlobalCharacter.  I need to search the end of each of the logs - is there a way to extract the last 10 lines of the Log stream for each object via SQL? Or is my only option to write an ObjectScript routine to walk the table and inspect each Log property one by one?

Thanks!

Hello gentlemen,

I hope you can help me because this is a very serious that I can't wait to resolve... Our back-up is currently taking 3 up to 4 Gb per day and we don't know why. We had 270 Gb yesterday and we are today at 274.3 Gb. We keep a computer history of the messages for only 50 days. Here is a picture of what's currently taking the most data place in our healtshare system:

(don't forget that our DB is also connected to the back-up, maybe it is related, I don't know)

Thanks you in advance,

Thomas

Hi community,

Do you have docker automl docker image with zpm?

In the first part we got a quick introduction on the IMAP protocol commands, now it's time to use IRIS and implement them and create our own IMAP client!

IRIS Email Framework

The IRIS platform has default interfaces and classes for working with email. Developers originally designed those artifacts for POP3 implementation. However, this doesn’t mean that we can’t use and extend these interfaces and classes to implement an IMAP client. So let’s talk about them:

• %Net.FetchMailProtocol: This is the base class for email retrieval. The IMAP client extends it.
• %Net.

⏯ Tell the World About Your REST APIs: The Benefits of a Centralized Developer Portal

Hello,

When using GetFieldStreamRaw(), by passing in a variable instead of using an output for the Remainder, will this affect how it is stored into a segment in a cloned message? I know it would usually output the remaining fields of the segment but in order to conform to a supplier's spec, they'd require "^^PDF" rather than the rest of the segment. Because the segment becomes immutable, the code below seems to be the way to do it.

Hi Experts

I am trying to pull the code tables Information and this code table has linked  code table not exactly obviously joined by SQL tables or columns. This is confusing me. Please can you clarify how to link these two tables. 

I will be generic to ensure, any privacy is protected

CT_Hospital has CT_Staff linked in.

When CT_Hospital has data, for that relevant hospital code, CT_Staff can be clicked and data entered. 

When I see in the Components - > Items I do not see any SQL table or SQL column common between CT_Hospital and CT_Staff. 

Question: How can I join CT_Hospital with CT_Staff.

Hey Community,

We want to hear from you! Give us your feedback on the past InterSystems Analytics programming contest! Please answer some questions to help us improve our contests.

👉 Quick survey: InterSystems Analytics Programming Contest Survey

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.

https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic…

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.

Newbie to working with silent installs.   is there a variable to pass in what/where you want to place your journal files?

⏯ 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.

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

Challenge details are here.

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?

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.

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.

Hey Developers,
