InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

QEWD is assumed by most people to only integrate with IRIS (or Cache) via a connection through IRIS's high-performance C interface.  This requires QEWD (and its Node.js environment) to be installed and configured on the same machine as IRIS.

I'm frequently asked if QEWD can run on a separate server (or servers), and access IRIS (or Cache) over a network connection.  The answer is yes it can, but the information on how to set it up in this way has been admittedly a bit tricky to discover.

So I've now rectified that, and pulled together all the information you need into one place, if you want

Question tom whalen · Dec 8, 2020

Hey folks - I'm working on some training materials and I'm looking for a paragraph or two and/or a diagram that illustrates their record IO flow.  Does anyone know of a good outline of how records are moved into the database and committed?

Question Ahmad Bukhtiar · Dec 5, 2020

Hi, we suddenly noticed that one of the edge storage increased by 30% and it was due to ERROR globals which was throwing repeated error for 7 days and it consumed 35GB space. Is there a way to log the storage of edge production on daily basis and compare the increase in storage with previous day and if increase is 5% more than trigger an email to system admit to look why the storage increased suddenly.

Is it possible see the execution plan of a SQL sentence in IRIS?

Like this:

explain plan for
select  e.ename,r.rname
from    employees  e
join    roles       r on (r.id = e.role_id)
join    departments d on (d.id = e.dept_id)
where   e.staffno <= 10
and     d.dname in ('Department Name 1','Department Name 2');

That returns this:

If you are looking for a slick way to integrate your IRIS solution in the Amazon Web Services ecosystem, server less application, or boto3 powered python script, using the IRIS Python Native API could be the way to go. You don't have to build out to far with a production implementation until you'll need to reach out and get something or set something in IRIS to make your application do its awesome sauce, so hopefully you will find value in this article and build something that matters or doesn't matter at all to anybody else but you as that is equally important.

Question Oliver Wilms · Dec 7, 2020

Hello,

I like to know if we need to have the message in a file to process a Record Map?

I am working with Interoperability Production that processes files /messages using Record Maps. My team was asked to redesign the solution for deployment in AWS. We use containers. We had problems with having multiple containers processing files from the same directory. We are considering Amazon Simple Queue Service instead of having files on a shared file system.

Has anybody migrated a Record Map to a Schema Definition to validate a message as a Virtual Document as I have seen with X12 messages?

In Oracle database, the synonym is an alternative name for objects such as tables, views, sequences, stored procedures, and other database objects.

You generally use synonyms when you are granting access to an object from another schema and you don't want the users to have to worry about knowing which schema owns the object.

Is IRIS SQL sintax has something like this: (oracle sintax)

CREATE PUBLIC SYNONYM suppliers
FOR app.suppliers;

This first CREATE SYNONYM example demonstrates how to create a synonym called suppliers. Now, users of other schemas can reference the table called suppliers

Those of you who run and support older-style legacy systems on IRIS may be interested in learning about and trying out a new framework I've built on top of my colleague Chris Munt's mg_web technology (details at https://github.com/chrisemunt/mg_web).

There are quite a few older-style and legacy applications out there whose useful life can be extended by making their functionality available as REST APIs.  To make this something that can be done quickly and easily, using modern, industrial-strength web servers, I've created what I'm calling mgweb-server:

InterSystems has corrected a defect that may cause Windows Telnet processes that are secured using SSL/TLS to hang indefinitely; this may then cause an instance to become unresponsive. This defect is present only on Windows platforms.

This defect affects:

  • Caché and Ensemble 2018.1.4
  • HealthShare Health Connect (HSAP) 15.032 built on C/E 2018.1.4
  • InterSystems IRIS and InterSystems IRIS for Health 2020.3

The problems caused by this defect can occur only when the instance is running Windows Telnet. Because Telnet is disabled by default, your system is susceptible to this defect only if it

Hi everyone,

I need to call a SOAP service using IRIS Interoperability and this SOAP service returns a Microsoft DataSet with a DiffGrams payload.

Do you know how to handle this kind of Objects ?

Question Joe Brun · Nov 26, 2020

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.
SuperServer has no queues or pools, and TCP connections are expensive (in terms of system resources).
Is there any real-world projects or tests/results?

As we all well know, InterSystems IRIS has an extensive range of tools for improving the scalability of application systems. In particular, much has been done to facilitate the parallel processing of data, including the use of parallelism in SQL query processing and the most attention-grabbing feature of IRIS: sharding. However, many mature developments that started back in Caché and have been carried over into IRIS actively use the multi-model features of this DBMS, which are understood as allowing the coexistence of different data models within a single database. For example, the HIS qMS database contains both semantic relational (electronic medical records) as well as traditional relational (interaction with PACS) and hierarchical data models (laboratory data and integration with other systems). Most of the listed models are implemented using SP.ARM's qWORD tool (a mini-DBMS that is based on direct access to globals). Therefore, unfortunately, it is not possible to use the new capabilities of parallel query processing for scaling, since these queries do not use IRIS SQL access.

Meanwhile, as the size of the database grows, most of the problems inherent to large relational databases become right for non-relational ones. So, this is a major reason why we are interested in parallel data processing as one of the tools that can be used for scaling.

In this article, I would like to discuss those aspects of parallel data processing that I have been dealing with over the years when solving tasks that are rarely mentioned in discussions of Big Data. I am going to be focusing on the technological transformation of databases, or, rather, technologies for transforming databases.

InterSystems Queryable Statement Metadata

Dynamic SQL allows the user to dynamic create, populate and query tables, call procedures and functions, and so on - all without writing any ObjectScript. Of course, this capability is completely normal for xDBC clients. InterSystems Dynamic SQL has been available in Caché for several years and is available in all versions of InterSystems IRIS. What I am about to describe should work for all versions of InterSystems IRIS and for all versions of InterSystems CE that support SQL Table-Valued functions.

If people are interested then I'll learn how to po

Hi Developers!

Want to raise security discussion today!

Let's discuss how InterSystems security for applications works. In general, the concept is clear: we have Resources (what to protect), Roles which combine a set of privileges and accesses to Resources and Users which can have this or that Role.

But there is also a concept of Application which also could have a Role.

So you either provide a Role for a User or for an Application.

What do you use in production? What is your strategy and why? Pros, cons?

Hi community!

Is it possible generate HTML documentation to my project ObjectScript classes (.cls)?

In Java we use Javadoc to do it. Javadoc get class comments and java metadata information and when I execute javadoc -d doc src\*, I get whole html documentation to my classes. Has IRIS something like javadoc? Is it documatic? If yes, how can I use it?

Question Fathima Zainab · Nov 21, 2020

Hello there, 

I am Zainab a Medical Practitioner for a leading hospital in India. 

But i am about to start my new clinic and gradually build it to a hospital as well. 

I already have a very strong patient Data Base but I am afraid that day by day as it is increasing i will need a better one to handle things. 

I have a considerable amount of knowledge in IT as well. that is when I came across this thing called IRIS. 

I also saw we can use it for free. 

I need more details please on this. 

I also see many versions of IRIS. Please clarify that for me as well please. 

Hope someone can help
