Hi Community,


In this article, I will introduce Python Flask Web Framework. Together we will create a minimal web application to connect to IRIS and get data from it.

Below you can find the steps we will need to follow:

• Step 1 : Introduction to Python Flask Web Framework
• Step 2 : Installation of Flask module
• Step 3 : Creation of web application using Flask
• Step 4 : Use of HTML Templates
• Step 5 : Installation of IRIS Python Native module
• Step 6 : Establishment of a connection with IRIS
• Step 7 : Transferring data from IRIS to Flask and displaying it

So Let's start with step 1

Step1-Introduction to Python Flask Web Framework

Flask is a small and lightweight Python web framework that provides useful tools and features that make creating web applications in Python easier. It gives developers flexibility and is a more accessible framework for new developers since it allows to build a web application quickly using only a single Python file. Flask is also extensible and doesn’t requires a particular directory structure or complicated boilerplate code before getting started.

It is my understanding that when a routine accesses a global it is temporarily stored in global memory. While the global is within global memory, any other routine would be able to readily access the global from memory and not from disk so long as the same node is being utilized.

Hi Guys,

I would like to know, how to setup a global structure in Cache classes storage type.

I want to set a global like below in Cache classes using Storage methods.

^A("ID1")="Name\Abb\Map"

^A("ID2")="Name\Abb\Map"

^A("ID3")="Name\Abb\Map"

...

If any lead it would be appreciated.

Thanks,

Arun Kumar Durairaj.

Hello,

I would like to get a list of all globals that have been read or written during a given context. In Portal, there are counters in dashboard that give the number of read/write to globals in general.

What I am looking for :

- some handler (eg: like $ZTRAP) that will be called everytime something is read/written to a global.

- to activate a "global log mode" in Portal that will dump some information to a file (like ^ISCSOAP for SOAP requests).

Making a blog using Python + IRIS Globals

Since I started to use internet (late 90's), I always had a CMS (content management system) present to make easier post
any information in a blog, social media or even an enterprise page. And later years putting all my code into github I
used to document it on a markdown file. Observing how easy could be persisting data into Intersystems IRIS with the
Native API I decided to make this application and force myself to forget a little of SQL and stay open to key-value database
model.

Process-private Globals can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage. For example lets define a pool, which can:

• add elements to a pool (ignoring duplicates)
• check if an element exists in the pool

Here's the class:

This is the related article to the package in Java Contest.

I decided to present a CRUD++ Global Editor based on IRIS Native API for Java.
++ because it’s a little bit more than just Create, Read, Update, Delete
Visualization of a global is always important to review results immediately.

I need to copy a bunch of globals from some crufty old databases to spanking clean brand new ones. GBLOCKCOPY has this cool feature that lets you create a batch of global names to copy and save the list in a batch. You can then execute the batch and go take a nap.

I like naps.

I need to do this for a number of old-new database pairs, but it's the same global names every time. Is there a way to export the batch configuration created the first time and import it to another environment/namespace? These databases will be spread across multiple hosts.

Thanks!

Hello community!

I'm facing a base growth issue, which is being generated by a process and an Ensemble feature.

When executing the process of cleaning up the message queues, the Ensemble “preserves” the Streams that were part of these messages, deleting only the Header and Body. In this way the database (of one of the namespaces) has grown around 60GB per day, which has been maxing out the disk capacity.

InterSystems informed that this is a characteristic and that it is explained in the documents mentioned below.

I have number of hosts on an Ensemble production that are not updating the %LastActivity property in the

^CacheTemp.EnsHostMonitor global. This in return create an issue with our dashboard software which is showing wrong results even as the host is processing messages without issues.

The Art of Mapping Globals to Classes (2 of 3)

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

This example is going to cram in 4 or 5 different things beyond what was covered in Part 1

Those of you that worked already with ECP might know that it operates not only across
operating systems, processor technologies (big-little-endian), but also -with limits- across versions in C/E.
This cross-version feature also includes IRIS (verified for 2020.1) and C/E (2018.3)

During a migration from a rather old Caché Version (2016.1) to IRIS
I met the problem to migrate Streams.
The difference in the storage Global is minimal
It's not a big effort to do it manually for a few streams.
But for some thousand streams I hope there is a tool already available.
But where?
