#InterSystems IRIS

We have been using DeepSee which has been the integrated Analytic Dashboard built over Cache Cubes. It works fine but it's visual capabilities are limited and most probably is getting phased out.If I am not wrong, Tableau is the suggested alternative to DeepSee .

Hi,

I'm a java developer,have  integration package for springboot?(maven or gradle)

Hi all - we just released the first episode of Season 2 for our Data Points podcast by Learning Services. This episode features a conversation with @Bob Kuszewski about Embedded Python. If you're a Python developer, or if you're simply interested in the functionality, check it out! For more information, head over to https://datapoints.intersystems.com.

Spring Boot is the most used Java framework to create REST API and microservices. It can be used to deploy web or executable web or desktop self-contained apps, where the application and another dependencies are packaged toghether. Springboot allows you do to a lot of functions, see:

Note: to learn about SpringBoot see official site - https://spring.io/quickstart

To create an web api application, with one or more microservices can you use Spring IDE for Eclipse or VSCode and use a wizard to config the technologies above that will be used into your app, see:

You select the technologies and create

(I wasn't able to find this in the docs or the Community, so feel free to point me to a reference that I missed)

How can I determine the effective User and Group that will be used when an InterSystems IRIS process is doing file I/O on the file system for UNIX?  Bonus points if you can tell me how to do it from within InterSystems IRIS as well as from the host OS.

Thanks!

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

Maybe someday you will need to use Adaptive Analytics but there is little information about this, so I decided to write an article on how to start developing a dashboard on Tableau using the Atscale cube.

You need a driver to connect. I use Cloudera Hive. You can download the driver from the official site:
https://www.cloudera.com/downloads/connectors/hive/odbc/2-6-1.html
Registration is required, and you can do it right there for free. You also need to know your OS and bit depth in order to choose the right version for download.
Installation is simple, no explanation required.

Hi Community,

I have json equivalent persistent object in pjsonObj variable. Final JSON example below.

{
     "Document": {
                    "FileExtension": "pdf",
                    "FileContent": "JVBERi0xLjUNCiW1tbW1DQo...(very large bsae64 string)"
                }
}

Here FileContent field in json will contain converted base64 string of very large pdf(10pages). I need to submit this json as a payload to REST endpoint.

below code is working fine. 

set tSC=##class(%ZEN.Auxiliary.jsonProvider).%WriteJSONStreamFromObject(.newobj,pjsonObj,,,1,"aelqtw")
$$$LOGINFO("json"_newobj.Read())

Hi everyone, i cant understand what is wrong in my query: 

ALTER TABLE MyNamespace.MyTable ALTER COLUMN CurrentColumnName RENAME NewColumnName

I just want to rename column name using sql.

I could not find any life example using this syntax.

SQLCODE for this query is -25:

-25 Input encountered after end of query

Quote from documentation:

• Rename the column using the syntax ALTER TABLE tablename ALTER COLUMN oldname RENAME newname.Renaming a column changes the SQL field name.It does not change the corresponding persistent class property name.

The InterSystems IRIS IntegratedML feature is used to get predictions and probabilities using the AutoML technique. The AutoML is a Machine Learning technology used to select the better Machine Learning algorithm/model to predict status, numbers and general results based in the past data (data used to train the AutoML model). You don't need a Data Scientist, because the AutoML it will test the most common Machine Learning algorithms and select the better algorithm to you, based in the data features analysed. See more here, in this article.

InterSystems IRIS has a built in AutoML engine, but

If your REST API need return a file to the client download, this is the source code that you could write (P.S.: extracted from the question https://community.intersystems.com/post/download-file-rest and its responses):

This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

Get the sample data to the migration process

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

• Source Database: MySQL database Docker instance with a sample database.
• Target Database:

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first. 

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table

Below is the basic command when table is already created and source file does not contain header row. 

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Apache Zeppelin it's a Multi-purpose notebook that allow you:

•     Data Ingestion
•     Data Discovery
•     Data Analytics
•     Data Visualization and Collaboration.

Apache Zeppelin interpreter concept allows any language/data-processing-backend to be plugged into Zeppelin. Currently Apache Zeppelin supports many interpreters such as Apache Spark, Apache Flink, Python, R, JDBC, Markdown and Shell.

It provides you a safe environment to get insigth of your data. You can take avantage of Zeppelin's higligths using both , JDBC and Spark IRIS native connectors.

I have seen the Cache Python binding documentation and would like to know if it's also possible with IRIS so I can write data and also read/get it from the DB? The cachesys folder does not contain any python libraries.

* In-Platform Agent-Based Simulation of a Connected Factory Cluster

Author: Sergey Lukyanchikov, InterSystems

1. Purpose

In this paper we prototype and explore how multiple agent-based models of robotic factories connected to other robotic factories (represented by their respective models) can be orchestrated using an all-purpose data platform – thereby simulating descriptive and predictive properties of a group of factories (a factory cluster). For the underlying prototype, NetLogo suite was used to do factory agent-based simulation (re-using “Robotic Factory” model [1]) while InterSystems IRIS

From IRIS 2021.2 is possible write Class Methods using the Python Language. I used this new feature to detect persons and objects into images, using ImageAI (https://github.com/OlafenwaMoses/ImageAI). The ImageAI creator defines it as: "An open-source python library built to empower developers to build applications and systems with self-contained Deep Learning and Computer Vision capabilities using simple and few lines of code." In this article you will learn how to apply AI Computer Vision to detect object and persons inside images.

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

If you need create a upload REST API with IRIS is very simple. Do these procedures:

From Postman client you send a file

P.S.: It is a multipart form with a file type using "file" in the name. The request type is form/multipart. See the http request:

POST /image-analyzer/postFile HTTP/1.1
Host: localhost:52773
Content-Length: 213
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="/C:/Users/yurim/OneDrive/Imagens/salesschema.png"
Content-Type: image/png

I have created a package that offers a utility to load a Global into JSON object and reverse     
to create a Global from this type of JSON object. Academic refers to the structure created.
Each logical node of the Global is presented separately with all its descendants.
Even if they don't contain any stored data.

Can we make any property immutable once it value is set? For example, I may have a property called RecordCreatedTime to track when the record is created in IRIS, and once it is set, I don't want anyone to modify the value. 

We recently encountered an Embedded SQL issue while upgrading to IRIS 2021.1, and thought the issue and workaround might be interesting to share.

Key takeaway:  Host variables in an ORDER BY clause of an embedded SQL query that is inside of a method don't work as expected. IRIS versions starting with 2020.1 are affected. As a workaround, add the host variable to the Method's PublicList list and "new" them so the embedded query has access to them.

It's come to our attention that the built-in license in the InterSystems IRIS and IRIS for Health 2021.1 Community Edition release is incorrectly set to expire on October 30, 2021.  

There is no impact to any production versions (the Community Edition is for development purposes), but developers will find that their instances stop running and should replace them with new ones.   For cases where replacing them is an issue, we have provided an override key.

I apologize for any inconvenience this may cause.

Hi....
I am trying to execute legacy routines from Cache 2018, into new environment with Iris 2021. I use new JDBC driver to make this connection, and change my java code to execute this legacy  routines. But I get this write error: <REMOTE EXECUTE INVALID WRITE> 
I changed the mnemonic routine to populate object and return this object to java. And the java class convert this object to json.
This is my simple classes used for this process, just to exemplification:

Hi Community

I have logged final generated json in the object script class using below statement

$$$LOGINFO("JSON = " _newMsg.Read())

where newMsg contains JSON stream, which contains nearly 1000000 + bytes.

In message viewer I am able to see Only some part of the json .

I want to capture all the json for my validation, how can i see total JSON in Management portal or any other source?

Thanks in Advance
