⏯ Introduction to InterSystems Reports

One useful feature of our REST framework is the ability for a dispatch class to identify request prefixes and forward them to another dispatch class. This approach of modularizing your URL map will improve code readability, enable you to easily maintain separate versions of an interface, and provide a means to protect API calls that only certain users will be allowed to access.

Overview

To set up a REST Service on your Caché instance, you need to define a dedicated CSP application and create the associated dispatch class that handles incoming requests. The dispatch class extends %CSP.

Hi,

I'm trying (and not succeeding) to build an index based on a collection property combined with a property, like:

Index Test On (Property, ListProperty(ELEMENTS).Property2)

For example, I have a class with this properties:
Property Simple As %String;
Property ListOfProp As List Of AnotherObject;

The, I try to create a simple index of one of the AnotherObject properties and I can compile and it creates the right index:
Index Test On (ListOfProp(ELEMENTS).Name);

But when I add a "normal" property, compiler miserably fails:
Index Test On (Simple, ListOfProp(ELEMENTS).

Hello Developers!

Previously, I shared with you all a handy operational analytics dashboard you can build to visualize key message processing metrics, such as number of inbound/outbound messages, average processing times, etc.

This time around, I’d like to walk you through an enhanced log monitor using a workflow many of you are already familiar with – working with alerts as messages inside a production, creating routing rules to filter and route alerts, and using pre-built components like the email adapter to send notifications at a granular level.

Hey Developers,

The InterSystems Full Stack Contest is over. Thank you all for participating in our exciting coding marathon! 

So it's time to announce the winners! 

Our big applause goes to these developers and their applications:

Hi everyone, i'm using a render server to make pdf output with zen report and everything was fine till recently i've been getting this error message and i have no idea what it means, i'd be very thankfull if someone could help or got into the same situation.

Error message:

ERROR #5001: net.sf.saxon.trans.XPathException: org.apache.fop.fo.ValidationException: "fo:table-body" is missing child elements. 
Required content model: marker* (table-row+|table-cell+) (See position 817:-1)

This error seems to be "random" if i try to render the same report without changing a single thing it works.

⏯ Big Data in InterSystems IRIS

I have a file passthrough service that should check for new new files every 10 minutes, process them and then wait again for 10 minutes, even if there are new files waiting in the source directory. The "CallInterval" value feels like a wrong tool for this need since it would keep the service "locked" for a maximun of 10 minutes before releasin resources.  Is there a better way than CallInterval to schedule the service to poll for files every 10 minutes?

Hi Team,

I want to convert numeric expression (202010011000) to datetime format(8/6/2018 9:10 PM)

Thanks,

So, it's time to give your vote to the best solutions built with InterSystems IRIS.

🔥 You decide: VOTING IS HERE 🔥

How to vote? This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

Hi developers!

We introduced a set of bonuses to all the participants of the Ful Stack Contest. 

And here is the table of current bonuses accomplishments:

GA releases are now published for the 2020.3 version of InterSystems IRIS, InterSystems IRIS for Health, and InterSystems IRIS Studio!

A full set of containers for these products is available from the WRC Software Distribution site, including community editions of InterSystems IRIS and InterSystems IRIS for Health. In addition, all containers are also available from the new InterSystems Container Registry. This article explains how to use the registry.

The build number for these releases is 2020.3.0.221.0.

By default InterSystems IRIS expose your endpoints using http, but can be necessary run https from your dev env and/or get public internet access to your app. You can buy or get a certificate and config a gateway, spending many hours or use a great public service called ngrok. Follow the steps:

1 - Run your app, I will use FHIR template as sample, see:

1.1 download the app: git clone https://github.com/intersystems-community/iris-fhir-template.git

1.2 go to the app dir: cd iris-fhir-template

1.3 run the app: docker-compose up -d

⏯ Develop a Python Flask app with InterSystems IRIS in 10 minutes

Hi,

I'm trying to ultimately create a function that I can use with HL7 messages that calls a stored procedure held on a SQL Server.

Initially I tried extending the function class to use the sql inbound adapter and/or EnsLib.SQL.Common, but this wouldn't work from the class method for the function.

Then I attempted to use the linked stored procedure using the wizard where it connected fine and I could find the sp but but it wouldn't return any data when ran. The test sp should just return an int.

The class document produced is this.

What is npm-iris?

Hey Developers!

We're pleased to announce the next competition of creating open-source solutions using InterSystems IRIS! Please welcome:

⚡️ InterSystems Full Stack Contest ⚡️

Duration: September 21 - October 11, 2020

I'm not sure how to go about building this scenario:

1. I FTP PUT a file "data.txt" to external directory
2. 3rd party processes that file
3. 3rd party creates a log file "errors.txt" into the same directory
4. My integration build should now 
   1. notice that there is a "errors.txt" file
   2. FTP GET that log file, delete it from server and process it 
   3. but we should also delete the "data.txt" from the server as it is "used" and should no longer be there. It is essential that "data.txt" must only be deleted if there is an "errors.txt" file and we have downloaded it

Can steps 4.1 - 4.

Hi, 

In Atelier I can click File --> New --> Class File, and File --> New --> Custom File etc to launch various wizards and templates to help me quickly create DeepSee KPI classes, %Installer manifests, Web Services and the like. Of course, all these are available through Studio as well. Is there anything similar in VSCode? If so where? I've looked at several videos and the documentation, but I haven't seen anything.

Thanks!

David

⏯ Data Platform Scalability

Hi developers!

Want to discuss with you the case of %Status.

If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.

What is does it gives you the responsibility to check the value or %Status of every system method you call.

E.g. if you save the data of the persistent class,  you should never call like this:

do obj.%Save()

you need to call:

set sc=obj.%Save()

if $$$ISERR(sc) do // something or quit.

Hi all, I am having problems trying to get Docker to run correctly on my Linux Mint machine.

I did the following:

1. Installed Docker.

docker --version

Docker version 19.03.6, build 369ce74a3c

docker-compose -v

docker-compose version 1.17.1, build unknown

2. Downloaded zip from https://github.com/intersystems-community/iris-fullstack-template/tree/42f9c174a9a4e63cb5eb3eb646abf3930a6e4d31

and unzipped it

3. Entered the following command:

docker-compose up -d

This generated the following error:

ERROR: Version in "./docker-compose.yml" is unsupported.

Hi Developers!

How do you handle errors with &sql a.k.a. embedded SQL?
I think I found a universal error-handling template which works in any situation:

&sql(SELECT * FROM Sample.Person)

if SQLCODE < 0 throw ##class(%Exception.SQL).CreateFromSQLCODE(SQLCODE,"Context description")

What is your choice?

The InterSystems IRIS has an integration engine with these core elements:

1. Adapters: are inbound (data/message input/request) and outbound (data/message output/response)  integration logic specialized in the type of data or message protocol (file, http, etc.). They are the interface to allows connect with source or target data repositories or systems.

2. DTL: is a component to mapping and transform data between two components in the flow orchestration.

3. BPL: is a component executing BPEL language to execute integration/orchestration flow.

4. Native API: is possible integrate with Java, .

⏯ InterSystems IRIS: Kafka, Schema Normalization and Service Enablement

Hi Developers!

Recently we discussed the naming convention on packages we deploy and even made some choices.

Here I want to have a conversation on the naming convention for unit tests.

Of course, we wish every good library has unit tests. Here is the documentation and some good articles(one, two, three) regarding it on the Developer Community.

Let's decide on the naming of UnitTests packages?

The suggestion is that unit test classes will all start with the UnitTest package name.

E.g. if your library's class name is:

johndoe.lib.class

The related unit test class will be:

UnitTest.johndoe.lib.class

What about folders?

The suggestion is that unit test classes will live separately from source classes, e.g. in /tests directory.

Here is the example of a repository with unit tests that are named and placed according to the proposal.

What do you think?

Hello 

Is there an example how to configure the webgateway on linux with kerberos in the dokumentation I found something but not realy in detail so far I understand I need two priniples one service prinple account with for example iris/at-mie-centos_iris.balmie.local@BALMIE.LOCAL-> there is my first problem with the dokumendation the @BALMIE.LOCAL is not dokumented but if you create a keytabfile with ktpass you can't create this without domain. For the secound user principle I am totaly lost how it should work must be both account in the keytabfile?

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program? There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki. Are there any other best practices?

There is a project github awesome. Maybe we should include the awesome-objectscript sections in it? And in the future for vscode to develop a plugin for awesome-objectscript ?

In Cache for Windows (x86-64) 2018.1.3 (Build 414U) I found something very useful

No reason apparently,

to many times executed :

[Database.SparseDBExpansion] Expanding capacity of sparse database /usr/irissys/mgr/iristemp/ by 1000 MB.

no details on audits, no traffic for that, no process to justify this, some ideas ?
