#InterSystems IRIS

Hot on the heels of the QEWD-JSdb announcement, QEWD-baseline provides a ready-to-run baseline environment for developing REST APIs.

The QEWD-baseline repository (https://github.com/robtweed/qewd-baseline) includes a fully-detailed tutorial on how to build RESY APIs using QEWD and the QEWD-JSdb database (running of course on IRIS).

Included in the tutorial is:

Hi Community,

for our forms validation we use XData to describe fields on server side.

These XData are in JSON like this

XData FormValidator [ MimeType = application/json ]
{
 {
  "username": {
   "required": true 
  },
  "email": {
   "datatype": "email"
  }
 }
}

When I try to use %JSON.Adaptor in same classes, IRIS throw an error at compile time

I have already asked a question about migrating an Oracle database to Caché, and I was promptly answered. Now, I have one more question, however it is more conceptual. In general, any tool defends its benefits, and looking at Caché's, among many, there is a lot of talk about speed. The question is, if I already have a database, and at the moment, its performance is not a problem, I would like to know what else could influence the change of this database? Remembering that it is functional and without any apparent problem.

Is there a way to compare the value in a source field against all of the values in a repeating field? For example, we have multiple DG1 target segments populated. Is there an easy way to check a source DG1 segments against all of the target DG1 segments? I didn't know if there is a wild card I can use for the comparison.

In Cache 2018, we were using a macro in a query that looked like this:

select $$GetExtraSQL^GetExtra('B',bddtl.odnumb,bddtl.odsnum,bddtl.oddsc1) as "Description", * from sqluser.bddtl

We could save that query as a view, and there was no problem with it.

In IRIS, if we put that query into SQL in the management portal, it still works, but if we save that query as a view, when we try to run a query on that view, we get a big error message:

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.

Welcome everybody!

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.

When there's a performance issue, whether for all users on the system or a single process, the shortest path to understanding the root cause is usually to understand what the processes in question are spending their time doing. Are they mostly using CPU to dutifully march through their algorithm (for better or worse); or are they mostly reading database blocks from disk; or mostly waiting for something else, like LOCKs, ECP or database block collisions?

Hello there community,

As I am interested in taking part in the Full Stack Development for IRIS, I tried to download the Software and get hands on experience with it.

The registration went well, but unfortunately I only got a mail with regard to the download but the Software did not get downloaded.

I need the help of you experts please.

Am I doing something wrong or did I just miss some thing or some steps in between these that needs to be fulfilled?

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.

Hello all,

I'm "playing" a little bit with IRIS as document database, as it seems really simple to use.

So far, creating a database and inserting documents is fine. Creating a Property so it can be indexed seems very useful and it works well when this property is created at the very beginning. But here my "problem": whenever a new property is added, how can the values be recalculated and inserted, so indices can be correctly updated?
