I have a couple of new namespaaces/databases that are read-only. I don't remember changing them to read-only, and although my username has %all (I installed the system), I am unable to change the "Always mount as read-only" property.
Say I have two horologs or timestamps, how can I compare them? I know that just time1 > time2 doesn't work because it will compare them as strings which is not correct.
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:
I am using a %GlobalStream to create as % stream.Object and writing that to a file but for some reason when I run that on the terminal I get <PARAMETER>zWrite^%Library.GlobalCharacterStream.1 and no file is created
I have tried the following here is my code and still get the same result any help appreciated
How we can reduce the size of cache.dat file? Even after deleting the globals of a particular database from management portal size of its cache.dat file is not reduced.
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.
Order is a necessity for everyone, but not everyone understands it in the same way

Disclaimer: This article uses Russian language and Cyrillic alphabet as examples, but is relevant for anyone who uses Caché in a non-English locale. Please note that this article refers mostly to NLS collations, which are different than SQL collations. SQL collations (such as SQLUPPER, SQLSTRING, EXACT which means no collation, TRUNCATE, etc.) are actual functions that are explicitly applied to some values, and whose results are sometimes explicitly stored in the global subscripts. When stored in subscripts, these values would naturally follow the NLS collation in effect (“SQL and NLS Collations”).
Caché prints to printers in a manner somewhat different from other Windows applications. Caché sends the data directly to the GDI Printer, without the usual interface. This is because the GUI interface can only be shown on a system desktop session and not in web browser and terminal sessions. Some printer drivers have problems with this method of printing.
Good day!
Is there an opportunity to debug the ISCAgent behaviour (in Linux)? ISCAgent uses /etc/iscagent/iscagent.conf as configuration file, but in docs I've found a description only for two parameters (port number and interface - http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...). Other parameters I can see by running /usr/local/etc/cachesys/ISCAgentCtrl status:
For many in today's interoperability landscape, REST reigns supreme. With the overabundance of tools and approaches to REST API development, what tools do you choose and what do you need to plan for before writing any code?
This article focuses on design patterns and considerations that allow you to build highly robust, adaptive, and consistent REST APIs. Viable approaches to challenges of CORS support and authentication management will be discussed, along with various tips and tricks and best tools for all stages of REST API development. Learn about the open-source REST APIs available for InterSystems IRIS Data Platform and how they tackle the challenge of ever-increasing API complexity.
The article is a write-up for a recent webinar on the same topic.
In this article, I would show how you can upload and download files from InterSystems products via http.
The questions about working with files over http arise fairly often on community and I'm usually linking to my FileServer project which demonstrates file upload/download but I'd like to talk a bit more on how we can serve and receive files from InterSystems products.
With the release of Cache 2016.1, JSON support was re-architected and made part of the core object model with the creation of %Object and %Array classes, which allow you to create dynamic JSON enabled objects and arrays.
On a recent demonstration I was working on, I had the need to create a REST web service that returned a JSON representation of a persistent object. After searching for methods that would allow me to accomplish this, ultimately I found none, until now.
The .NET Core Identity model has an IPasswordHasher<> interface for for
Hashing a password so that it can be stored in a database
Verifying a provided plain-text password matches a previously stored hash.
I am getting invalid password errors during the login process when the .NET Core Identity model computes a hash from a plain text input and compares it to a password hash value I've returned from Caché. The default hashing algorithm is PBKDF2 with HMAC-SHA256, 128-bit salt, 256-bit subkey, and 10,000 iterations (detailed article on .NET Core Identity PasswordHasher). The algorithm Caché uses is probably different which may be why I am getting errors.
A good writer is supposed to draw you in with the title and bury the answer somewhere in the article. I suppose this makes me a bad writer – don’t think less of me, my whole feeling of self-worth comes from the opinions of internet strangers!
Hi All, Can you please tell me how to get the Size of the Global Subcript.
In Cache 2016 - they are using ##Class(%GlobalEdit).GetGlobalSizeBySubscript()
For Older version how to get the GlobalSize of the Subscript.
Because the method is not exist in Older Versions and all.
The release of IBM POWER 8 processors with AIX 7.1 introduced up to 8 SMT threads per processor core (logical or physical). Which SMT level (1, 2, 4, or 8) to use can be confusing and varies based on multiple factors. This article is meant to help with a starting point for your specific application.
Firstly, if running on a version of 2014.x or older, it is advised to use SMT 4 or lower. SMT 8 with those older versions of Cache' has shown a decline in performance and scaling in benchmarking applications.
I have a process that is importing lots of data from an external file, but every now and then I come across a STORE error.
I know that the STORE error is occurring in the %Save method of the class but I know very little else and I think its something to do with a lage amounts of Related Objects.
Is there a method of finding out more information regarding this error i.e. which actual object was being saved etc etc.
In PHP, I'm able to utilize the implode and str_getcsv functions to convert a comma-delimited string to a tab-delimited string. The following is an example.
InterSystems products (IRIS, Caché, Ensemble) already include a built-in Apache web server. But the built-in server is designed for the development and administration tasks and thus has certain limitations. Though you may find some useful workarounds for these limitations, the more common approach is to deploy a full-scale web server for your production environment. This article describes how to set up Apache to work with InterSystems products and how to provide HTTPS access. We will be using Ubuntu, but the configuration process is almost the same for all Linux distributions.
Can anyone please provide me with a guide I can follow to create an entry in Cache's SSL/TLS configuration that would allow me to "speak" to an website via the Post method using SSL.
I need to simulate functionality that is provided by my browser but from with Cache.
The topics I have are:
1. From where do I source the certificate that will be used for this process?
2. What processing must I do on it to make it acceptable for Cache's SSL/TLS
3. What settings are required when filling the the form
