#InterSystems IRIS

Is it possible to configure mirror of the DB between two VMs using APIs like that one? I assume, based on the description, it can be done but on the same instance but I'm not sure how to do that for two separate VMs. I know how to use IRIS portal and set up Mirrored Members connections but now trying to automate that process.

Thanks!

Hi, developers!

Currently, I'm working on a project that requires highly dynamic event management. In the context of the Java programming language, my first instinct should be to opt for the "Observer Pattern", which is an approach to managing interactions between objects by establishing a notification mechanism. It allows multiple observers to react to changes in the state of a subject autonomously, promoting code flexibility and modularity. If you are not familiar with this design pattern, check out Wikipedia to find more information about it.

While it's natural and commonly used in certain programming languages as Java and C++, in ObjectScript, it's quite a different story.

Hi community!

In this article, I'm excited to introduce my latest application, Journal File Indexer. The development of this application is rooted in the portal idea DPI-I-270.

In short, this application lets you load and index a log file in a database.

Why?

If you've ever used the log file search function in the management portal, you may have encountered a timeout error or even a blank page. This problem usually occurs when searching a large journal file. Journal File Indexer solves this problem by considerably increasing the speed of searches once the file has been loaded into the database.

Another problem arises during the restoration process. When searching for global entries in a log file to restore old or new values, the management portal doesn't have this specific functionality. A routine must therefore be coded to achieve this. Journal File Indexer comes to the rescue, incorporating a restore function!

This question originally appeared in the comments of the post: The Art of Mapping Globals to Classes (5 of 3)

Hey

I need to know how to exclude row after checking his data, for example:

^global(1,2)=a*b

^global(1,3)=a*c

if $P(^global(key1,key2),"*",2)=c Q

how can i do this?

thanks

What user can be used to initiate IRIS container in emergency access mode on startup?

Recently viewed a demo on the new Dynamic Objects in InterSystems (we are still running 2016.1); together with the upcoming IRIS data platform I started thinking about possibilities of building dynamic databases. That is, I can imagine some projects were it might be really nice to store dynamic objects and then run sql queries on them without ever defining the fields of the dynamic objects (i.e. not at storage, but only if you run your sql query).

Hi Community!

When you run IRIS container out-of-the-box and connect to it via terminal e.g. with:

docker-compose exec iris bash

You see something like:

root@7b19f545187b:/opt/app# irissession IRIS

Node: 7b19f545187b, Instance: IRIS

Username: ***

Password: ***

USER>

And you enter login and password every time.

How to programmatically setup docker-compose file to have IRIS container with OS authentication enabled? And have the following while entering the terminal:

root@7b19f545187b:/opt/app# irissession IRIS

Node: 7b19f545187b, Instance: IRIS

USER>

In the world of APIs, REST is very extended. But what happens when you need more flexibility in your data-fetching strategies? For instance letting the client to choose what fields is going to receive. Enter GraphQL, a query language for your APIs that provides a flexible alternative to REST.

In this post, we will:

• Compare REST and GraphQL.
• Dive into the basics of GraphQL: Queries, Mutations, and HTTP.
• Build a simple GraphQL server implementation using Graphene, SQLAlchemy, and Flask over data in InterSystems IRIS.
• Explore how to deploy your GraphQL server as a WSGI application in IRIS.

I want to create a scheduler to montor the status of list of backend jobs ( say limit is 10). there going to be job queue. Need to pick a job form job queue when one of the current processing job is finished.
What is the best way to implement this

I am trying to replicate a REST call that I am able to make via a Postman call within a EnsLib.REST.GenericOperation.

It's been a while since I have messed around with trying to make external REST calls. When I execute my REST call, tSC is coming back with an error and I am trying to pinpoint why. I tried turning on ISCLOG = 5 but when calling the REST Operation from the Testing tool it is not logging anything to the ISC log.

Pyodbc supports calling stored procedure , but if the IRIS Stored Procedure ROWSPEC has a column with datatype specified as %Date or %Time, Pyodbc fails to fetch it and throws this error.

"

pyodbc.Error: (' 2201', '[ 2201] [Cache ODBC][State : 22018 ][Native Code 22005]\r\nERROR #388: Unknown error, code 22005 (22005) (SQLGetData)')

"

on printing the cursor execute description, pyodbc reads the column as <int>.

Hello all,

I am in a bit of a situation where I could get your help please.

I want to get certified with IRIS, but I also do see that there is an availability named Cache.

Are they both the same or different? if different please explain it to me as how?

Also what is the difference between IRIS, IRIS for Health, Deep Sea? Please explain to me.

Also what do you think I should get my self certified with?

Please leave your comments below.

Cheers.

The InterSystems IRIS is a great data platform and it is met the current features required by the market. In this article, you see the top 10:

Note: this list was updated because many features are added to IRIS in last 3 years (thanks @Kristina Lauer)
