During a major version upgrade it is advisable to recompile the classes and routines of all your namespaces (see Major Version Post-Installation Tasks).

do $system.OBJ.CompileAllNamespaces("u")
do ##Class(%Routine).CompileAllNamespaces()

To automate this administration task and keep a log of any errors, below is an example of a class to import and compile into the USER namespace that you can use after each upgrade : admin.utils.cls

Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

Question Guilherme Koerber · May 5, 2022

Hello community!

I'm creating a script to remove an item (component) from the Ensemble production, I know there is a manual way to do it but as there are several components the idea is to use a script to be faster.

I tried using %Delete() and doing a select on Ens.Config.Item, but this ends up generating several errors in production. Does anyone have any idea how I can do this simply?

From time to time, we get the previous question in support, something or someone is using more licenses than expected, and we need to find what. 

We have two scenarios. The first scenario is when we realize that the licenses are exhausted when the application does not work or when we try to connect through the terminal and get the "lovely"

Question Scott Roth · Apr 22, 2022

A question has come up that I am not finding the answer for.... Does the daily purge process re-index EnsLib.HL7.SearchTable or other SQL tables?  In looking at the purge process documentation I am not seeing anything that mentions EnsLib.HL7.SearchTable. Do we have to manually constantly re-index tables that we create? For example I created another search table based off of EnsLib.HL7.Search table, will I need to constantly watch this as it grows? How do tables get index, is there some kind of mechanism that automatically does it, or are we responsible for indexing tables ourselves? We are

IMPORTANT NOTE InterSystems no longer provides a separate InterSystems Reports Server container. To run containerized InterSystems Reports Server, use Logi Reports Server container and your InterSystems Reports Server license. Documentation.

InterSystems Reports is powered by Logi Report (formerly named JReport), a product of Logi Analytics. InterSystems Reports is supported by InterSystems IRIS and InterSystems IRIS for Health. It provides a robust modern reporting solution that includes:

  • Embedded operational reporting which can be customized by both report developers and end users.
  • Pixel-perfect formatting that lets you develop highly specific form grids or other special layout elements for invoices, documents, and forms.
  • Banded layouts that provide structure for aggregated and detailed data.
  • Exact positioning of headers, footers, aggregations, detailed data, images, and sub-reports.
  • A variety of page report types.
  • Large-scale dynamic report scheduling and distribution including export to PDF, XLS, HTML, XML, and other file formats, printing, and archiving for regulatory compliance.

InterSystems Reports consists of:

  • A report designer, which provides Design and Preview Tabs that enable report developers to create and preview reports with live data.
  • A report server which provides end users browser-based access to run, schedule, filter, and modify reports.

From InterSystems documentation.

This article focuses on the Server part of InterSystems Reports and provides a guide on running Report Server in containers while persisting all the data.

Question Scott Roth · Mar 18, 2022

We are trying to track down the source of Orphaned messages and noticed that we are unable to query EnsLib.HL7.Message with any kind of WHERE or ORDER BY clauses in our SQL statement.

I know EnsLib.HL7.Message is a system table, but is there a way we can add additional Indexes to the table to make the query run better/faster without affecting the system?

Myself and the other Technology Architects often have to explain to customers and vendors Caché IO requirements and the way that Caché applications will use storage systems. The following tables are useful when explaining typical Caché IO profile and requirements for a transactional database application with customers and vendors.  The original tables were created by Mark Bolinsky.

In future posts I will be discussing more about storage IO so am also posting these tables now as a reference for those articles.

The Documentation team in InterSystems Learning Services is happy to announce the new InterSystems IRIS Server Migration Guide!

Have you ever wanted to copy, move, or clone an instance of InterSystems IRIS to a new server? Maybe the operating system on the old server is no longer supported, or maybe you want to add a new member to an existing mirror. Migrating your application databases is easy, but what about your tasks, users, roles, resources, and other security settings? What do you need to migrate, and how best to do it?

Question John Jacobs · May 16, 2018

Is there a group in or outside of this community for discussion of DTM issues? I am working on a conversion to Caché for a client but in the meantime, he is still live with his DTM system and a system management issue has arisen. The convo:

Client: Do you know how to increase the page limit in MUMPS DTM?  One version of my database I use for one customer is telling me I have reached my page limit.  I have increased the page limit in the database you are reviewing; so I figure there is a setting I am missing.

This post provides guidelines for configuration, system sizing and capacity planning when deploying IRIS and IRIS on a VMware ESXi. This post is based on and replaces the earlier IRIS-era guidance and reflects current VMware and InterSystems recommendations.

Last update Jan 2026. These guidelines are a best effort, remember requirements and capabilities of VMware and IRIS can change.

Question Scott Roth · Oct 6, 2020

I was wondering if there was a certain procedure or documentation on securing (Https://) the Web Portal into IRIS/Ensemble?

Currently we are using LDAP Delegated Authentication to access the Web Portal using LDAP. However as more and more emphasis is put on securing applications within networks, I can see Management/Security asking us to make sure that the web portal is more secure.

Maybe I am not looking at the right place for documentation, but is there a Best Practice guide, set of instructions, or Online learning that can help guide me in trying to make our environment more secure?

(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!

Hi, everyone!


I want to share a personal project that started with a simple request at work: 

Is it's possible to know how many Caché licenses we are using? 

Reading other articles here in the community, I found this excellent article by  David Loveluck 


APM - Using the Caché History Monitor
https://community.intersystems.com/post/apm-using-cach%C3%A9-history-monitor

So, using David's article, I started using Caché History Monitor and to show all that information. 

When facing the question: Which cool tech should I use?

You might of seen or might of not seen my earlier post about Exporting a Production from 2018.1 to import it into 2021.1. I was able to get the export working, however I noticed in reviewing the data within the export, our previous Workday XML Schemas that we imported via XSD files were not in the export. When walking through the export process under Message Schema or vDoc Schema I could not find the missing XML Schema structures. Why aren't XML's part of the export process if they are used within the Production? Where are the XML Schema's kept within the Ensemble structure so I can see if

Question Scott Roth · Jan 6, 2022

We are migrating from AIX to Linux and part of our testing is trying to figure the best method to migrate the code. I am trying to export an entire Production, however I keep running into an error...

Error generating export list for production osuwmc.TestClin and all items may not be listed.
ERROR #5002: Cache error: <CLASS DOES NOT EXIST>zgetRecordandComplexMapClasses+34^Ens.Config.Production.1 *(No name)

I went through any Complex Record Maps, and recompiled them but I am still getting the same error

Does anyone know how I can track down this error and the culprit?

Thanks

Pouring The Coffee: Creating and scheduling a task

Don't you wish a fresh, hot cup of coffee could be waiting for you right when you get into the office? Let's automate that!

Cache and IRIS come with a built-in Task Manager, which should have a familiar feel to those used to using the Windows task scheduler or using cron on Linux. Your user account will need access to the %Admin_Task resource to use it, and you can access it in the management portal under System Operation -> Task Manager. When first installed, there are roughly 20 types of task that you can schedule.
