The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…
This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.
I have been using evaluation version of Cache 2017.2, it was working fine and I was using Cache studio, SMP & Cache Terminal/console till yesterday.
Today, cache was in shutdown status, then I restarted. But, Cache terminal is not working and showing as Access Denied while otherthings like studio and SMP is working as expected. I checked all security level services on SMP, all are fine and enabled.
Can anyone help me to diagnose the problem and make it working.
Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.

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 hope this is the right forum to ask this type of question, but I'm running out of ideas.
For reasons beyond my control, we run a version of Intersystems Caché (2013.1) that is not supported by Atelier. As such, I use Caché Studio to do my development. The issue I have is, I don't run Windows or MAC, but Linux (Ubuntu 18.04 in my case). I've successfully managed to get Studio working using Wine and pretty much everything is usable.
A few months ago I touched on a brief note on "Python JDBC connection into IRIS", and since then I referred to it more frequently than my own scratchpad hidden deep in my PC. Hence, here comes up another 5-minute note on how to make "Python ODBC connection into IRIS".
Sometimes, it comes in very handy (especially for the EAV model) to use array properties in a class and be able to qickly search by their elements: both the key and the value.
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.
In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.
I was wondering if there is any way to count elements from an array. I guess not as an array could be multi-dimensional and that would be a problem to return the number of elements inside the array.
At the global summit in Phoenix, we (Lite Solutions) will be presenting a tool performing static code analysis on ObjectScript source files. You can see it in action at this URL:
Let's pretend you are working on a project where you may be retrieving a URL for some purpose and you have the need to be easily able to parse apart that URL to get the various components that make up the URL.
I am trying to create a list of id's which are of type integer. I have created a class like below and then I am trying to call the class from a BPL to first initialize the list. In the BPL, I have an assign action that is using set and a context variable setup to hold the list data. The property is using the class I have created, ##class(MSI.IN835.EOBList).%New(). I keep getting an error back saying the method does not exist. Why does it not like the %new method? I am new to cache object script, so if their is a better way to do this, I am open to that as well.
I have a Cache classes with %TimeStamp (e.g. 2016-04-18 12:29:11) and %Date (eg. 64027) properties. And I have a javascript client app, which needs full CRUD over this properties.
But in javascript date/time are defined by ISO8601 (e.g. timestamp 2016-04-18T12:29:11Z, date 2016-04-18).
As you see, timezone is lost. Docs for $zdth in timeopt (5) state: Specify time in the form "hh:mm:ss+/-hh:mm" (24-hour clock). The time is specified as local time. The following optional suffix may be supplied, but is ignored: a plus (+) or minus (–) suffix followed by the offset of local time from Coordinated Universal Time (UTC)
All time
