Hi Developers!

I stuck with one interesting problem.

For example, let's use this template repo. If you build this container A using docker-compose and then run the container it exposes REST-API which is available on:

localhost:52773/person/all

The question is how to make this REST-API accessible from another docker container B running on the same machine? E.g. with IRIS 2019.4 Community from this repo?

The problem is that for the second container localhost it's something which belongs to container B.

I think I need to set up a network between containers somehow. E.g. using docker-compose. But is there any simpler way?

Class Queries

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name.

Some of you on the Developer Community have probably interacted with @Luca Ravazzolo if you are interested in cloud and container topics... If so, you'll enjoy Episode 2 of our new podcast — we chatted with Luca about Kubernetes and the InterSystems Kubernetes Operator. He does a great job of explaining the technology and its benefits here!

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

Dasha.AI is a platform that allows you to create and manage voice interfaces for your applications. One of Dasha’s distinctive features is that most users believe they are talking to a human, not a robot.

Voice is the most natural way for people to interact. Dasha allows to use voice interface to interact with your application as naturally as communication between people.

You may have seen earlier this week that we launched a brand-new learning podcast called Data Points! There are three episodes released, one of which was a really interesting discussion with Thomas Dyar — a product specialist here at InterSystems focused on machine learning. Take a listen and reach out if you're interested in exploring more about IntegratedML!

Cache Unit Test with jenkins

Hi, everybody,

I've been reading some posts in the community but I haven't been able to come to a conclusion. Here's my point.

I have a cache code, and following this guide https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?K... but I can't understand how to run this from jenkins for example, without using the console, and thus automate the process. That is to say, if it were possible to do it, what steps should I follow.

Thank you very much

I understand RecordMaps can be used to send delimited files through a production without custom coding. The data segments are delimited by tilde character followed by $Char(10) in Linux/Unix. When I test the same IO data in Windows, I have $Char(13) and $Char(10) instead of just $Char(10). I like to use just tilde character for record delimiter and ignore $Char(13) and $Char(10) between the tilde and the leading data of the next segment / record. Is this good idea or not if someone wants to generate classes will it override code?

I've recently encountered a HS Caché that won't start informing that Collation 30 is not available, but I have not found an easy way of knowing what collation is 30.

I've found that the following command returns the ones from the current locale, but not from all locales:

Set Rset = ##class(%ResultSet).%New("%Library.Collate:CollationList")

d Rset.Execute()

While (Rset.Next()) {zw Rset.Number_": "_Rset.Name}

Thank you
