#InterSystems IRIS

I'm almost running out of disk space so I want to move 1 DB to a different hard drive.  
It's a rather simple but lengthy action during a shutdown of IRIS.  
But is this somehow possible under runtime in a stand-alone installation?  
I'm looking for kind of a "local drive failover"  
note: Mirror or Shadow is not an option.  

Hey everyone.

I have been revisiting our backup strategy, and spotted that IRIS supports VSS (Volume Shadow Copy Service) in Windows. This is quite attractive as an approach, as it automatically calls the external freeze and thaw commands.

However when calling these manually, there's quite a few parameters that can be set, and the documentation around VSS only states that the freeze/thaw commands are called.

Is there a way of controlling the parameters used, or at the very least know what the defaults are?

Ever noticed that the Type column of the Web Applications page in the Security section of Management Portal is showing you redundant information?

Hi All!

Examining the page here I see we have one-to-many and parent-child relationships supported in the InterSystems Objects model.

Do we support one-to-one too?

I'm looking for a way to have an IRIS db distributed over several (hw) drives.  
Without touching the internal data structures (e.g. mapping) !  
Are there any options in file systems to achieve this "splitting" or "appending" ? 

Historic background:

• Once upon a time CPUs worked on 32 bit
• Files could mostly not be larger than 2 GB
• And Caché had a (forgotten) option to EXTEND a db to a next file of another 2 GB max. and a next ...

This EXTENT was excellently suited to move fresh and active data
to a faster spindle for more performance.
 

After running an extensive block of daily statistics my IRISTEMP has expanded dramatically.   
But FreeSpace shows 97% unused and FREE space.   
How can I shrink IRISTEMP in runtime without shutdown and manual intervention
(which was the traditional approach)

Hi guys,

I've created an iris command line utility to interface the Linux command line with Interface IRIS

It maybe of use to some of the community

Hello, in a zen page sometimes I find document.getElementbyId("ID") to set a propertybut also zen("ID").setPr.... So what is the real difference and limitations of each?

What is Distributed Artificial Intelligence (DAI)?

Attempts to find a “bullet-proof” definition have not produced result: it seems like the term is slightly “ahead of time”. Still, we can analyze semantically the term itself – deriving that distributed artificial intelligence is the same AI (see our effort to suggest an “applied” definition) though partitioned across several computers that are not clustered together (neither data-wise, nor via applications, not by providing access to particular computers in principle). I.e., ideally, distributed artificial intelligence should be arranged in such a way that none of the computers participating in that “distribution” have direct access to data nor applications of another computer: the only alternative becomes transmission of data samples and executable scripts via “transparent” messaging. Any deviations from that ideal should lead to an advent of “partially distributed artificial intelligence” – an example being distributed data with a central application server. Or its inverse. One way or the other, we obtain as a result a set of “federated” models (i.e., either models trained each on their own data sources, or each trained by their own algorithms, or “both at once”).

InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.

The InterSystems IRIS can be extended using Java or .NET components and its frameworks inside Object Script source code.

In Studio you could open a class directly via it's name, without having to traverse the package tree with multiple clicks until arriving at the desired class.

You would Ctrl + O or (File -> Open) and be able to simply type in the class name, for example:

You press Enter, and viola - the class is opened.

How do you achieve this in VSCode?

Hi Community,

We're pleased to invite you to join the upcoming webinar "Connect Data and Application Silos to Accelerate Business Insights At Scale" on April 8 at 10:00 AM EDT!

The explosion of business systems and processes and their resulting data silos has made an overarching view of enterprise information more challenging than ever. Join two data management industry veterans as they discuss the latest progress in data management technology, working with transactional AND analytic data, and how the financial services industry is addressing challenges to speed insight and innovation.

Now Sapphire enable you load CSV to IRIS. See the steps:

1) Create a sample CSV file using Excel (save file as CSV):

2) Follow these instructions to install Sapphire into your enviroment: https://openexchange.intersystems.com/package/SAPPHIRE

3) Access Sapphire web page. Go to top menu Import > Load CSV

4) Configure access to your IRIS target instance, select new table, set your new table name, click Choose button and load your csv file and click upload. Click Get Definitions.

Keyword: Pandas DataFrame, IRIS, Python, JDBC

Purpose

Pandas DataFrame is popular tool for EDA (Exploratory Data Analysis). In ML tasks, the first thing we usually perform is to understand the data a bit more. Last week I was trying this Covid19 dataset in Kaggle. Basically the data is a spreadsheet of 1925 encounter rows with 231 columns, and the task is simply to predict whether a patient (linked to  1 or more encounter records) would be admitted to ICU. So it's a normal classification task, and we would as usual use padas.DataFrame to take a quick look first.  

ZPM-Registry – is the package registry for the ZPM package manager.

As you probably know, the ZPM package manager is configured by default to work with the public community registry https://pm.community.intersystems.com/, which currently has more than 150 packages published.
You can install and configure your own registry for use in your organization.

Starting from version 1.1.2, zpm-registry includes the Proxy feature.
Now you can link your own registry to another (for example, the public registry of the community).

AWS Glue is a fully managed ETL (extract, transform, and load) service that makes it simple and cost-effective to categorize your data, clean it, enrich it, and move it reliably between various data stores.

I usually save the path in database like "C:\folder\picture.png", but now i want to save the photo in Iris or Caché database? Which way is better to recover the image and to maintain the original quality?

Hi!

I need to know how long time a message has been in a possible queue before our business service starts handling the message. Is it possible to read with objectscript or another way?

The business service is an EnsLib.SOAP.Service

Grateful for answers

Hi,

is it possible to access a property defined as %List from sql? I´d like to search for a object containing a specific value in it´s %List defined property. Is there a predefined sql function for that within IRIS?

best regards,
Sebastian

Hi Community,

I'm developing an IRIS environment for a project and I would like to take some questions to pass on to the developers that I haven't found yet here in the community:

1. Is it possible to debug the process in VSCode in real time?

2. How can we use the terminal in VsCode for some configuration or just import applications (Example: Web Terminal)?

Background: We have our own SQL map that predates InterSystems'. A program writes an XML file for each table map class as $system.OBJ.Export would. $system.OBJ.LoadDir loads the XML files into .cls files.

The reason is a long story, but we need to update parameter EXTENTSIZE (only) in existing classes. This does not seem to happen. As a test I used $system.OBJ.Export to make an XML file and edited EXTENTSIZE in the two places it appears in the XML:

<StorageStrategy>SQLStorage</StorageStrategy>
<Parameter name="EXTENTSIZE"><Default>1001</Default></Parameter>

Hi Developers!

Recently we released the updated version 0.1.3 of ObjectScript Package Manager (ZPM) which comes with the support of simplified ObjectScript sources folder structure.

What 'simplified' does mean?

Before 0.1.3 ZPM expected the following structure:

/src

---/cls  - for ObjectScript classes

---/cls/package_name/class_name.cls

---/cls/package_name/class_name2.cls

---/mac - or Mac ObjectScript routines

---/mac/package_name/mac_routine.mac

---/mac/package_name/mac_routine2.mac

---/inc - for ObjectScript macro include files.

---/inc/package_name/include_file.inc
