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.

Hi Developers!Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.PrerequisitesMake sure you have Git, Docker, and VSCode installedInstall Docker and ObjectScript extensions into VSCodeSign in or Create an account on GithubHere we go!To start development you do the following:Use the template repository and create your own repository on Github.Clone your repository with git on your desktop in terminalOpen repository in VSCodeUse docker-compose.yml to build the container with InterSystems IRIS and import all the ObjectScript from /src folder into USER namespace of IRIS container.Open a terminal to IRIS and call the imported ObjectScript codeMake a change to ObjectScript code and compile itCommit and push changes to your GitHub repositoryCheck the screencast below: Or check the long video with all the explanations.What's next? Start learning ObjectScript with Online Learning and Documentation.Also check Beginner posts, Best Practices and ObjectScript code guidelines.Happy coding! Noticed some good stuff in @Dmitry.Maslennikov's iris-template repo and updated mine foundation template for development with IRIS Community Edition in ObjectScript. It's much easier now to run ObjectScript instructions in Dockerfile. Check the basic Dockerfie: ARG IMAGE=intersystems/iris:2019.1.0S.111.0 ARG IMAGE=store/intersystems/irishealth:2019.3.0.308.0-community ARG IMAGE=store/intersystems/iris-community:2019.3.0.309.0 FROM $IMAGE USER root WORKDIR /opt/irisapp RUN chown ${ISC_PACKAGE_MGRUSER}:${ISC_PACKAGE_IRISGROUP} /opt/irisapp USER irisowner COPY Installer.cls .

It go me up and running pretty fast (as title says!). Couple of things: - The notes/documentation say that code will be loaded into USER namespace, however it's actually being loaded into IRISAPP (as configured in docckerfiles). - The jason.config is pointing to USER namespace so any new files and changes to existing will be actually loaded into USER instead of IRISAPP - Make sure it's all consistent - The webapp (irisweb) is missing a config for the directory where to store files. I fixed this by modifying the app in management portal. Need to address the installation file/dockerfile - Haven't been able to make CSPs flow to the container the same as classes. I'm sure I'm missing something but haven't figured out what yet. Any tips? Maybe I'm placing files in the wrong location? Right now I created a csp/irisweb folder under src folder. - The notes/documentation say that code will be loaded into USER namespace, however it's actually being loaded into IRISAPP (as configured in docckerfiles). Because I made an update to the code recently) And not to the documentation) PR is welcome, or I'll change it by myself soon. Or add an issue! - The jason.config is pointing to USER namespace so any new files and changes to existing will be actually loaded into USER instead of IRISAPP Yes, it's a bug from previous version. Need to be fixed, thanks! - The webapp (irisweb) is missing a config for the directory where to store files. I fixed this by modifying the app in management portal. Need to address the installation file/dockerfile Cool! Do you want to make a PR? - Haven't been able to make CSPs flow to the container the same as classes. I'm sure I'm missing something but haven't figured out what yet. Any tips? Maybe I'm placing files in the wrong location? Right now I created a csp/irisweb folder under src folder. You need to COPY this files from /csp in sources to /usr/irissys/mgr/csp/yourwebapp in Dockerfile OK, I'll give it a try and create a PR once I have a new config file. Thanks! Hi @warlin.Garcia ! I pushed the commit into the repo which fixes Namespace and README issue, thanks! Thank you. I'll check on it. Do you have any tips to make csp changes flow in realtime the same as classes do? I've modified the dockerfile to copy the contents of my csp directory into the container, however my edits to CSPs are not flowing realtime which forces me to rebuild the container everytime to get my updates. Sure! just add the volume mapping in docker-compose.yml file which maps folder /csp in sources into /csp directory in docker. Got it all working. Thank you! Updated the Installer.cls file - now you can set up the namespace and path in variables "Namespace" and "app" respectfully at the top of Installer.cls. <Default Name="Namespace" Value="IRISAPP"/> <Default Name="app" Value="irisapp" /> This is convenient if you need to install the app to the namespace with your name. Notice, that if you want instantly edit and compile the code of your project with VSCode don't forget to change the Namespace parameter in settings.json too.

First webinar on InterSystems API Management! We are pleased to invite you to the upcoming webinar in Russian: Introduction to InterSystems API Management on November 21 at 10:00 Moscow time (GMT+3)! As you might have heard, we recently introduced the InterSystems API Manager (IAM) - a new feature of the InterSystems IRIS Data Platform,enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In this webinar I will highlight some of the many capabilities IAM allows you to leverage. InterSystems API Manager brings everything you need: to monitor your HTTP-based API traffic and understand who is using your APIs; what are your most popular APIs and which could require a rework. to control who is using your APIs and restrict usage in various ways. From simple access restrictions to throttling API traffic and fine-tuning request payloads, you have fine-grained control and can react quickly. to protect your APIs with central security mechanisms like OAuth2.0 or Key Token Authentication. to onboard third-party developers and provide them with a superb developer experience right from the start by providing a dedicated Developer Portal for their needs. to scale your API demands and deliver low-latency responses There would be a live demo. This webinar is for System Architects, Developers and DevOps Engineers.Time: November 21 at 10:00 Moscow time (GMT+3)! The language of the webinar is Russian. Register! Any chance of repeating this webinar in English? Hi Fred! Have you seen this introduction? Hi Fred, I just published the API Management session from Global Summit 2019 on DC YouTube channel. Hope it will be useful for you! 😉 Is there any interest in English Webinar? Please reply in comments if you would like a rerun of this or similar webinar but in English! Yes

Hello InterSystems Community, We're excited to announce that we've completed our first Open Exchange submission for InterSystems platforms. BridgeWorks VDM is an ad hoc reporting and graphical SQL query builder application that was designed for any user who needs access to their SQL projections in InterSystems Caché, InterSystems IRIS, InterSystems IRIS for Health databases as well as access to InterSystems DeepSee and InterSystems IRIS BI Cubes with minimal SQL scripting experience. VDM features: Drag and a drop query builder Interactive Data and Pivot grids Charting and Gauges Data Visualizations Banded Report Writer Report Scheduling and Batching Web reporting capabilities Data export to PDF, Excel, HTML, Word, CSV, Text Files, Image and more VDM leverages the Managed Provider for .Net to communicate with InterSystems databases, and no ODBC drivers are needed to access the SQL projections for InterSystems Caché, InterSystems IRIS and InterSystems IRIS for Health. VDM accesses DeepSee.RESTClient.cls for building MDX queries and communication with InterSystems DeepSee and InterSystems IRIS BI. Video walk through: jQuery(document).ready(function ($){$("#youtubexM5LKB0G25E").css("height",$("#youtubexM5LKB0G25E").css("width").replace(/[^0-9]/gim,"")/(560/315));$(window).resize(function(){ $("#youtubexM5LKB0G25E").css("height",$("#youtubexM5LKB0G25E").css("width").replace(/[^0-9]/gim,"")/(560/315));});}); Notes: While VDM is not a SQL syntax editor, the graphical query builder can be bypassed and SQL scripts can be pasted directly into the Advanced Query form for execution against your InterSystems database. The InterSystems DeepSee and InterSystems IRIS BI features are currently EAP. Community feedback on our project is appreciated.

This article introduces InterSystems iKnow Entity Browser, a web application which allows to visualize extracted and organized text data mined from a large number of texts, powered by InterSystems iKnow technology, which is also known as InterSystems Text Analytics in InterSystems IRIS. Feel free to play with the demo of this tool or learn more about it on InterSystems Open Exchange. I started the development of this project in late 2016. From now on, my iKnow Entity Browser is used around the world by those who use InterSystems technology in their stack and those who do text mining. This article should have appeared earlier, however, it's never late to tell something about the useful stuff! What InterSystems Text Analytics is About InterSystems iKnow (or InterSystems Text Analytics) is an embeddable NLP technology which allows to extract meaningful data from texts. Well, not only just to extract this data, but also to gather it, link, filter and prioritize. As a result, InterSystems iKnow provides a solid ground for building data applications for data mining. From the programming perspective, iKnow provides a rich API which allows to embed this technology to any application, regardless of its programming language. iKnow Entity Browser uses this API to visualize the processed data in a form of a tree of concepts and relations. Before InterSystems iKnow Entity Browser was released, the only out-of-the-box solution available for data exploration was the embedded iKnow viewer, which is shipped together with InterSystems' Cache-based and IRIS products. This viewer features many useful tools primarily for searching something in the processed text (in iKnow it is called domain), while iKnow Entity Browser is created also to visualize and organize concepts in a text. iKnow Knowledge Portal Look iKnow Entity Browser iKnow Entity Browser is an open-source project, meaning that anyone can contribute to its core. Here's the list of features that have been developed: visualization of similar and related concepts as a tree (snowflake diagram), zoom in and out support; graph editing tools: selection, deletion, undo & redo operations; data source customization, which also enables exploring the graph on remote servers; customizable tabular view of all entities presented on a graph, which can also be exported as a *.csv spreadsheet; mobile-friendly, touch-compatible, responsive user interface. iKnow Entity Browser Graph Demo Installation iKnow Entity Browser installation is pretty straightforward. Download the latest release (XML file) of the application and import it into iKnow-enabled namespace (for example, SAMPLES). This works with all latest InterSystems product releases, including InterSystems IRIS data platform. To import XML file, you can drag & drop the file onto the Studio (Atelier) window. Alternatively, you can import the file using the system management portal, in system explorer — classes. Then, open your browser at http://localhost:57772/EntityBrowser/ web page (change the host/port respectively to your server's setup and mind to append the trailing slash / at the end of the URL). To delete the application, simply delete the EntityBrowser package from Studio/Atelier. The installed web application will be deleted automatically if it wasn't modified since installation, the same way as it gets created during the installation. Currently, to use iKnow Entity Browser in different namespaces, you need to import it to each iKnow-enabled namespace, and manually set up web application (for example, you can clone /EntityBrowser application and rename it). Change the settings inside the web application to corresponding ones in this case (read the customization guide below). If you installed iKnow Entity Browser on the server and made the web application public, you can connect to this server from any front end, for example, even from this demo application. Customization Application's setting menu, located in the top right corner of the user interface allows to customize the appearance and data source. In the settings menu, you can specify the following (see the image below): Data source URL, which identifies the server with installed iKnow entity browser (/EntityBrowser web application). Domain name. When you create a new domain in InterSystems iKnow, you specify the name of the domain. This name goes into domain name input. A seed concept name which builds the graph. By default, iKnow Entity Browser builds the graph starting from related concepts to the seed concept you specify, however, you can change it to be similar concepts, using the drop-down menu on the left side from the seed concept input or the drop-down menu in the main view if enabled. Whether or not to place the seed concept input in the main view. Whether or not to place the query type drop-down menu in the main view. Whether or not to show hidden nodes in the tabular view. Hidden nodes are those which are not expanded in a view but present in a query result. Columns that are displayed in a tabular view. Here you can customize the column name and select a value it displays (ID, inbound edge type, label, score, spread, frequency, parent concept's label, parent concept's id). Reset all settings to defaults. iKnow Entity Browser Settings The Graph Once the seed concept is specified in settings, iKnow Entity Browser builds a graph of similar or related concepts to the seed concept. You can play with this graph by dragging its nodes, however, the physical force will always try to organize it in a form of the snowflake diagram. The graph can be edited using the controls in the bottom of the screen. This includes undo/redo buttons, zoom in/out and reset zoom buttons, reset selection button, unlink and delete selection buttons. Hovering over any of these buttons displays a tooltip. Menu with controls In case you need a list of selected concepts, you can toggle a tabular view by pressing on the corresponding button in the top right corner. Everything you do on the graph stays in sync with the tabular view and vice versa. In the tabular view, once you hover over one of the rows, the corresponding node is highlighted on the graph. If you click the row, the graph view automatically focuses on the corresponding node. As well as on the graph, you can click buttons in table rows to select/deselect nodes. Tabular View Once you have a selection of nodes, you can export them as a table in *.csv format. Press the tabular view button in the top right corner for the table to appear and then you'll find the "Export" button. This will export all selected nodes in a form of a table, the same table as you have in a tabular view. There's More iKnow Entity Browser is just one of the numerous projects I did for InterSystems corporation. Here are some if you haven't seen these projects yet: WebTerminal, Visual Editor, Class Explorer, Light Pivot Table, GlobalsDB Admin. Find these and other InterSystems-related projects on InterSystems Marketplace. All of my projects are open sourced, allowing others to contribute. The code of these projects is available on GitHub. You can also use their code as an example to build your own application on top of InterSystems' products. If you take a closer look, you'll find out that most of them are installable packages, shipped in a single XML file. If you are curious about using the same strategy for your packages, check this article. Hope you'll find iKnow Entity Browser and other projects useful! Enjoy! Thanks for posting Nikita. Your visualization has indeed been extremely helpful in showing what iKnow entities are all about to new audiences and is easily embeddable in applications where large numbers of entities need to be explored or navigated! Thank you Benjamin! Glad to hear this Thanks for posting. I followed the install directions and customized the domain and seed word and the web browser seemed to indicate that it was processing and never stopped. CPU usage was overloaded and I'm having to reboot the server. Has anyone else encountered this? In EntityBrowser.API class set PAGESIZE parameter to 100 and compile the class. Thanks, that fed me results quickly. What is this doing? I'm familiar with PAGESIZE as it relates to number of rows returned. I've noticed nodes now that say to display x more. So is this returning first 100, top 100, or something different? TOP 100.
