Hi Community, We're super excited to share with you our upcoming appearance at the 10th anniversary Big Data Minds DACH 2022 in Berlin, Germany! ⏱ Date & Time: 18 – 20 September 2022 📍 Location: Maritim proArte Hotel Berlin, Friedrichstraße 151 | 10117 Berlin This event is organized by we.CONECT and InterSystems will lead a “Challenge your peers” session titled “Looking for a silver bullet in data management - data mesh, data fabric or something else entirely?” We will be discussing questions like: Which data management technology is best suited to ensure the long-term success of a company today? In your opinion, what are the main requirements for a modern data management solution? If you could change anything about the way your company handles data today, what would it be and why? How many data silos do you estimate exist in your organization? If you and your employees were given access to all relevant data in your company tomorrow, what project would you want to implement first on that basis? Who do you think should have supremacy over data: the respective department/project team, the central IT department or the management? What would be the biggest hurdles in your company that would have to be overcome for an overarching view of all data? Don't miss this great opportunity to discuss the different approaches for modern data management to efficiently get "From Big to Smart Data" in a company of like-minded peers! >> REGISTER HERE <<

A new release of ZPM has been published 0.4.0 New in this release Added support for Deployed packages, publishing, and installation Support for multiple registry servers, e.g. public community registry, private corporate, and so on, including Python embedded code Ability to show all versions and package origin in search Fixed issue for packages with preload code The expanded limit for the length of arguments in Invoke Multiple registries It is now possible to define more than one registry in your instance, so, you may use public community, testing, or private corporate registry at the same time. Just use another name for the registry For instance, we can add the testing registry zpm:USER>repo -n test -r -url https://test.pm.community.intersystems.com/registry/ -user test -pass PassWord42 test Source: https://test.pm.community.intersystems.com/registry/ Enabled? Yes Available? Yes Use for Snapshots? Yes Use for Prereleases? Yes Is Read-Only? No Deployment Enabled? No Username: test Password: <set> zpm:USER>repo -list test Source: https://test.pm.community.intersystems.com/registry/ Enabled? Yes Available? Yes Use for Snapshots? Yes Use for Prereleases? Yes Is Read-Only? No Deployment Enabled? No Username: test Password: <set> registry Source: https://pm.community.intersystems.com Enabled? Yes Available? Yes Use for Snapshots? Yes Use for Prereleases? Yes Is Read-Only? No Deployment Enabled? No And in addition to this change, it's now possible to redefine properties for registry by only passing the name of the existing registry. For instance to update only the password zpm:USER>repo -n test -pass PassWord42 test Source: https://test.pm.community.intersystems.com/registry/ Enabled? Yes Available? Yes Use for Snapshots? Yes Use for Prereleases? Yes Is Read-Only? No Deployment Enabled? No Username: test Password: <set> Deployed packages Since version 0.4.0, ZPM now supports deployed packages. The minimal module.xml may look like below, important here is Deploy="true" flag <?xml version="1.0" encoding="UTF-8"?> <Export generator="Cache" version="25"> <Document name="demo.ZPM"> <Module> <Name>demo</Name> <Version>1.0.0</Version> <Description>DEMO.</Description> <Keywords>demo</Keywords> <SourcesRoot>src</SourcesRoot> <Resource Name="Sample.Demo.PKG" Deploy="true"/> </Module> </Document> </Export> The process of development is the same as previously, you should use the load command to load the module in development mode (by default) zpm "load /home/irisowner/myproject" In this case, zpm will load source code, and ignore Deploy flag due to DeveloperMode, so, you can modify the code. Publishing To publish deployed module, you have to use your own registry, or you may use the testing community registry for tests. zpm:USER>publish demo -DPublishTo=test [USER|demo] PrepareDeploy START [USER-PACKAGE-429287|demo] PrepareDeploy SUCCESS [USER-PACKAGE-429287|demo] Reload START (/home/irisowner/zpm/packages/demo/) [USER-PACKAGE-429287|demo] Reload SUCCESS [demo] Module object refreshed.

And log shows each step and the namespace where that step was performed. An additional parameter -DPublishTo=test, defines the name of the registry where to publish the package. And if you wish you may change the release number with parameter as well -DNewVersion=1.0.0 Installation deployed packages Installation is as usual, but you will not be able to install deployed package, or any package in production mode if you already have the package installed in development mode. zpm:USER>install demo ERROR! Cannot install 'demo' over previously installed in developer mode You would need to uninstall the package installed in development mode, or use a clean namespace or instance for it. It's important to remember, that deployed package does not have source code, so, the packaging should be completed on a specific version of IRIS that which developer support. The registry supports multiple platform versions for one specific version of the package, so, during installation zpm will request a version for the platform. To compare versions it uses only major and minor parts of the IRIS version, e.g. 2022.2, 2021.1. When you will try to install the package on an unsupported version of IRIS, will get the error zpm:USER>install test/demo ERROR! Deployed package 'demo' 1.0.0 not supported on this platform 2022.1. Successful install zpm:USER>install test/demo [USER|demo] Reload START (/usr/irissys/mgr/.modules/USER/demo/1.0.0/) [USER|demo] Reload SUCCESS [demo] Module object refreshed.

Great release! @Dmitry.Maslennikov For deployed code, does this prevent source (src or module.xml) from being stored on the disk as well? At least for the developer. Yes, the final package has no source code at all, it only delivers compiled code, so, that's why it requires the exact version of platform to build on and install Great release! If classes with Embedded python methods can be deployed in a deployed (with no source) mode? I did some tests with Embedded Python as well, and it keeps working even without source code. Great! Does deployed code work with BPL BPs? Only if defined as classes in module.xml. But, probably can be improved to support any way. This is great, thank you! Should the "Deploy=true" be provided for every resource? If the module contains two resources, and one is in Deploy mode and the second without, will the second be deployed with source code and the first without? Right, only resources marked as Deployed=true will appear without source code in the final package Nice work!! What is another way? They are classes, right?

Hi guys, I thought I test the InterSystems IRIS for Health 2020.1, the Docker image. but for some reason, the container only lives for about 10 seconds and I can see from the message.log file that as soon as IRIS starts it then performs shutdown thus ending also container.

Different options of docker prune could help. E.g. docker system prune -f Read more in @Dmitry.Maslennikov article. Unfortunately, that did not help. I'll investigate further. it turned out to be access privileges issue with license file, what a silly mistake of mine. Anyway, thank you Evgeny for pointing me to some useful info, anyway!

Preview Mode was added to InterSystems IRIS Business Intelligence to give designers a quick view of what their resulting Pivot Table will look like without needing to wait for the results to fully execute. This can be beneficial when designing pivot tables because if you are dragging and dropping elements to see how they look/work in your pivot table and seeing if they have the desired data. Since you are exploring and designing, you don't necessarily care about the results at the moment, but you would still like to see how your table looks with the changes you have made. I previously wrote "DeepSee Tips & Tricks: Auto-execute" which can also be beneficial while designing Pivot Tables. However, with Auto-execute, you see no preview after dragging and dropping elements. It is more geared towards someone who knows exactly what their end result will be, someone who wants to prevent the intermediate executions while dragging and dropping elements. Preview Mode is more for exploring what the data looks like and how it can work in the Pivot Table. At any point, you can simply turn Preview Mode off by using the checkbox at the top of Analyzer. You can also click the "Show All" button towards the bottom of Analyzer to see the full results of the current pivot. Adding new elements will continue to execute in Preview Mode. The Documentation also has a brief explanation about Preview Mode.

Hi Community, New video, recorded by @Benjamin.DeBoe, is available on InterSystems Developers YouTube: ⏯ What Developers Love About InterSystems IRIS InterSystems Product Manager @Benjamin.DeBoe talks about what developers love about InterSystems IRIS Data Platform - the data and code are "next to one another" making your code very efficient.

Hi Community!You're very welcome to watch a new video on InterSystems Developers YouTube, recorded in a new format called "Coding Talks":Developing with Docker and InterSystems IRIS Community Edition In this video, presented by @Evgeny.Shvarov, you will know how to develop InterSystems IRIS solution on ObjectScript using Docker with example of dockerised InterSystems IRIS repository.Read how to dockerize your repo here.And...A little bit about our new video format: Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.So! Enjoy watching the video and you're very welcome to share your own ideas/themes for our new video format in the comments to this post!Stay tuned! This article needs to link to pre-requisite articles to be of much use. For a developer who is used to writing ObjectScript in Studio on a local Ensemble installation, the starting point for this video is so far removed from what is familiar as to make it pretty useless. Similarly, for a newcomer to InterSystems development there is little here to latch onto to get things started. As part of a series this might well make a lot of sense, but as a standalone video its like demonstrating how to build a space rocket by showing an astronaut strapping themselves in for takeoff - it felt like all of the hard work had already been done. Hi Duncan!As mentioned above the video is a sort of "work through" for this article. Could you be more specific what doesn't work?BTW, just Yesterday I recorded another one which shows how to start a totally new app with Github, IRIS on docker and VSCode. Hope it will answer some of your questions.

One of my colleagues at InterSystems encountered an unexpected issue when running InterSystems IRIS on a Macintosh in a container using Docker for Mac. I’d like to share what we found, so you might avoid running into similar issues.The ProblemThe task at hand was running a Java application with XEP to do a large data load into IRIS. When running the data load, the write daemon hung soon after starting the job, with messages like these in messages.log: 05/21/19-14:57:50:625 (757) 2 Process terminated abnormally (pid 973, jobid 0x00050016) (was a global updater)05/21/19-14:58:52:990 (743) 2 CP: Pausing users because the Write Daemon has not shown signs of activity for 301 seconds. Users will resume if Write Daemon completes a pass or writes to disk (wdpass=98). This problem was completely reproducible and was very mysterious, so Support got involved. What we foundWe were able to start the SystemPerformance utility while reproducing the problem and discovered the issue readily.In the iris.cpf file, the cache for 8KB databases was set to 4GB:globals=0,0,4096,0,0,0 That looked reasonable for an instance running on a machine with 8GB of memory. Since this was a test, the Mac was otherwise not heavily loaded. However, not all of that system memory was actually available to IRIS, as we saw in the output of the Linux free command inside the container: Memtotal, used, free, shared,buf/cache,available,swaptotal, swapused, swapfree, 1998, 331, 322, 513, 1344, 1003, 1023, 11, 1012, 1998, 340, 312, 513, 1345, 994, 1023, 11, 1012,. . . 1998, 272, 72, 1563, 1653, 44, 1023, 105, 918,. . . 1998, 123, 67, 1770, 1807, 12, 1023, 870, 153,. . . 1998, 135, 54, 1777, 1809, 14, 1023, 1023, 0, Only about 2GB was actually available. During the heavy data load, IRIS rapidly consumed the database cache until all memory and swap space available was exhausted; at which point the instance hung.The CauseDocker relies heavily on some key Linux technologies, particularly cgroups and namespaces, that aren’t available natively on platforms like Macintosh and Windows. On these platforms, Docker uses a Linux virtual machine internally: in the case of the Macintosh, this is provided by HyperKit. And as we found, it is possible to overallocate memory on this platform and configure IRIS with more memory than is actually available. If you are using Docker for Mac as your development platform, keep this internal VM in mind and size memory appropriately. I think it would be good to add screenshot like this, to show how to configure memory limits in macOS. In Windows should be quite similar I think. Thanks Dmitry! It looks like you did it.

Preview releases are now available for the 2019.3 version of InterSystems IRIS and IRIS for Health! Container images are available via the WRC's preview download site.The version number for these releases is 2019.3.0.302.0 Public announcements will be made shortly, with separate announcements for each product.

Preview releases allow our customers to get an early start working with new features and functionality. They are supported for development and test purposes, but not for production. How about community edition in docker hub, when to expect it there?

Hi Everyone! Please watch the new video on InterSystems Developers YouTube, recorded by @Sourabh.Sethi6829 in a new format called "Coding Talks": A SOLID Design in InterSystems ObjectScript In this session, we will discuss a SOLID Principle of Programming and will implement it in the example.We have used Caché Object Programming Language for examples. We will go step by step to understand the requirement, then what common mistakes we use to do while designing, understanding each principle and then complete design with its implementation via Caché Objects. Additional resources: CodeSet Presentation Also, check out the first part of "Locking in InterSystems ObjectScript" Coding Talk. If you have any questions or suggestions, please write to @Sourabh.Sethi6829 at sethisourabh.hit@gmail.com. Enjoy watching this video!
