Hey Developers,

I want to try SAM in AWS. I followed these steps:

docker pull store/intersystems/sam:1.0.0.115

git clone intersystems-community/sam: System Alerting and Monitoring (SAM) (github.com)

git clone https://github.com/intersystems-community/sam

tar zpxvf sam-<version>.tar.gz

tar zpxvf sam-1.0.0.115-unix.tar.gz

$ cd sam-<version>

cd /home/ec2-user/git/sam/sam-1.0.0.115-unix/

$ ./start.sh

In your browser, visit:
http://<ip-address-of-host-where-SAM-runs>:8080/api/sam/app/index.csp
You'll be prompted to login.You can use standard InterSystems IRIS credentials like _SYSTEM/SYS.

So I've got the IRIS AMI spun up in AWS EC2; it seems to be running fine.  
I've added an EBS volume to it for persistent storage, and now I'm pondering how to make it actually do something useful.  

What's the best way to do deploy code to this instance?  I can think of a few ways to do it, but what's the least painful way?  Push my code to an S3 bucket and figure out how to load it at system start?  Github project?  

I have described my efforts to optimize IRIS Mirror deployment in AWS ElasticContainer Service (ECS) in my prior article.

IRIS Mirror in the cloud (AWS) | InterSystems Developer Community | AWS
 

I have come to the opinion that IRIS Mirror is not as reliable as needed when deployed in ECS. The root of the problem is the fact that ECS randomly assigns one of the available IP addresses to each EC2 host or Fargate task it starts.

These get stored in iris.cpf file in MapMirrors section as shown here:

Hey everyone as you may know I am a beginner and I am kindly asking for some assistance in a problem I have been solving. The problem is that I am calling a user defined function within a procedure called occupiedseatsAdj and the compiler comes up with this error. 

From what I understand I can call a user defined function from within a procedure (correct me if I am wrong) as shown below.Is this the correct way or should I create a .Mac file and include it somewhere within the above mentioned cls file ?

I have been working on redesigning a Health Connect production which runs on a mirrored instance of Healthshare 2019.We were told to take advantage of containers.We got to work on IRIS 2020.1 and split the database part from the Interoperability part.We had the IRIS mirror running on EC2 instances and used containers to run IRIS interoperability application.Eventually we decided to run the data tier in containers as well.Later we switched from using EC2 instances to Fargate “server-less” compute.

The first installment of this article series discussed how to read a big chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. The second installment discussed how to send files and their names wrapped in a JSON format. 

Now let’s look closer at the idea of sending large files in parts to the server. There are several approaches we can use to do this. This article discusses using the Transfer-Encoding header to indicate chunked transfer. The HTTP/1.1 specification introduced the Transfer-Encoding header, and the RFC 7230 section 4.1 described it, but it’s absent from the HTTP/2 specification. 

It's possible to enable Ctrl+C / Ctrl+V in IRIS Terminal for Windows.

To do that, open Terminal and select Edit > User Settings and enable Windows edit accelerators. This settingspecifies whether the Terminal enables the common Windows edit shortcuts (Ctrl+C, Ctrl+V, Ctrl+Shift+V), in addition to the basic Terminal edit shortcuts (Ctrl+Insert and Shift+Insert).

After that Ctrl+C / Ctrl+V would work.

Also <SYNTAX> errors after incorrect copy/paste go away.

I'm wanting to write a query in SQL that will return a row with a count for each day for a given month or year for a specific operation or configname.  The following is a start but I'm not finding what I want in the documentation to parse out the TimeLogged field of the table.  Nay help is appreciated.

SELECT count(TimeLogged), ConfigName
FROM Ens_Util.Log
where TimeLogged like '2021-07%'
and ConfigName = 'operation_Name'
group by TimeLogged

Hi developers, 

We have just published an update to the Deltanji version control extension for Visual Studio Code.

When used in certain Deltanji workflows, triggering an automatic checkout on first keystroke could result in the developer working on an outdated copy of the code and only being notified of this later when saving their changes. In order to prevent this from happening checkout now reloads the document immediately. 

Error messaging has been improved in two areas - when attempting to cancel code that is not checked out, and when trying to register new code onto a withdraw system. 

We have also improved interoperability between the Deltanji extension and the InterSystems ObjectScript one, as well as its handling of multi-component objects.

If you're already a user of Deltanji then your extension with automatically update. You can find out more information on Deltanji and the latest release here. 

Hi, Is there a way to connect to a MYSQL ODBC? I tried using the SQL Connect class but getting an error.

Set conn=##class(%SQLGatewayConnection).%New()

But I am getting an error :

Please can you advice how I can do this?

Alerts are automatic notifications triggered by specified events or thresholds being exceeded.

InterSystems Documentation

I have a Business Service connected to a machine with ~100 sensors. BS receives sensor values once a second.

Several conditions determine if a Business Service should raise an alert (it's a list of: sensor id > threshold).

I have three questions:

1.  Should I write these conditions as a business rule and call this rule from the Business Service, and if the rule returns 1 call SendAlert? Or is there some other way to do that?
2. Business Rule returns a reason for the rule

Introduction

This is a csvgen UI frontend in Angular 8. The aim of this project is to easily import csv file to Iris from a web ui.

Demo

Install with ZPM

It will automatically install the dependency of csvgen and sslclient

zpm "install csvgen-ui"

This will create two new endpoints :

• One for the Rest API for uploading files

• /api/{namespace}/csvgen/

• One for the UI

• /csp/{namespace}/csvgen/index.html

Stand alone demo on docker

Run the server

docker-compose up -d

UI

The UI is per-namespcae, this mean it will be available only for the namespace where csvgen-ui is install. For example :

http://localho

Do you know a CRM that is built with InterSystems IRIS or Caché or Ensemble on a backend?

Hi,

While starting newly created production I am getting below error:

Continuing the description of work on the use of the openhl python module in productive mode.

Since the version of iris with Embedded Python, does not yet have a final release, it is already necessary to use it in production now. We decided to back up the service for exporting requests to a xlsx file on a separate server, and save the query result in a global in a separate database.

This database was made networked, local for the service server and remote for the product server. The communication between the prod server and the service was implemented using a rest service.

So: on the server in

Hi developers!

How to build an analytics solution with InterSystems IRIS?

To begin with, let's agree on the points of what is the analytics solution - and this could be a very wide topic. Let's limit the set of solutions to those you can present in the Analytics contest.

There are three kinds of analytics solutions that we will review here: monitoring, interactive analytics, and reporting. 

Monitoring

The typical monitoring solution consists of an online dashboard with KPIs that are being actively updated.

The key use case is of monitoring is to visually observe the KPI of fresh data every moment to react in case of an emergency.

Interactive Analytics

This solution supposes a set of interactive dashboards with filters and drill-downs.

The key use case is to explore the data with filters and drill-downs making business decisions upon graph and table data visualization.

Reporting

Reporting solution provides a set of static (usually) reports in a form of HTML or pdf documents that deliver the data in graph and text form in a predesigned form and could be sent via email.

The typical use case of a reporting system is to obtain reports on a given period that will illustrate the status of the product, process, service, sales, etc that is crucial for the business.

How InterSystems products could be used to build such solutions? Let's discuss this below!

Hi folks!

Is there a way (function) to know the name of the database for data of the current namespace?

I take the case where we have one database for data and another database for code in a namespace.

Thanks!

I have been working within Objectscript for a few months and I am seeking assistance today because all of the help files within the docs.intersystems.com domain are currently down and they wont be back up until next week. (I raised a special ticket for this) 

I have been trying to figure out how to  convert a binary number 0101001 in to a decimal number using a variable called CNumber and I have tried using the method below and it hasnt worked.I think it may be due to the fact that this assumes an array or some sort.

Hi folks!

Want to share a lifehack with you on ObjectScript highlighiting withing VSCode for script files.

Script files are just files with lines of ObjectScript that we feed anywhere, e.g. into IRIS during Docker baking procedure.

Typical usecase - here is the Scriptfile

here is the Dockerfile where we feed it.

And here is how it looks like usually in VSCode:

Coudl be more beautiful, right?
