Caché Localization Manager

CLM is a tool for localization/internationalization/adding multi-language support to a project based on InterSystems Caché.

Imagine that you have a ready project where all the content is in Russian, and you need to add an English localization to it. You wrap all your strings into resources, translate them into English and call the necessary resource for Russian or English when necessary. Nothing tricky, if you think about it. But what if there are lots of strings and there are mistakes in Russian (or English)? What if you need to localize in more than one language – say, ten? This is exactly the kind of project where you should use CLM. It will help you localize the entire content of your project into the necessary language and retain the possibility to correct entries.

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.

Question:

Where can I find the openssl command line tool for Windows?

Answer:

The openssl command line utility comes with Unix, but not with Windows. It is used for working with security certificates.

The main site is

https://www.openssl.org/

There are no binaries on this site but in the Community section there is a link for binaries which leads to:

Recently I wrote about automatic removal of system methods from the codebase.

Today, I'm ready to present you a working solution (codename: SMR) for this task.

This article explains the basics of OpenVMS file structures, from a Caché prospective, and what you need to know to read and write any OpenVMS file with Caché, even the files with difficult file structures.

I tried to make atelier look more like XCODE with this simple trick or tip: change the default font to SF Mono and size 14.

To do it I did:

1) Install SF Mono font in the system which is the default font for XCODE and needs to be installed in order to use it.

You can find it in: /Applications/Utilities/Terminal.app/Contents/Resources/Fonts

Double Click SFMono-Regular.otf file and install it. You will get a warning of "serious problems" but it will work all right.

In this post I would like to talk about the syslog table. I will cover what it is, how you look at it, what the entries really are, and why it may be important to you. The syslog table can contain important diagnostic information. If your system is having any problems, it is important to understand how to look at this table and what information is contained there.

Beginning in Caché 2013.1, InterSystems introduced Outlier Selectivity to improve query plan selection involving fields with one atypical value.

In this article, I hope to use an example 'Projects' table to demonstrate what Outlier Selectivity is, how it helps SQL performance and a few considerations for writing queries.

After upgrading an Information Exchange/HealthShare instance that has a registry namespace, you may notice that the Caché audit log gets filled with frequent login failures by the HS_Services user (check this by going to Management Portal > System Administration > Security > Auditing > View Audit Database). Clicking the “details” shows event data like:

Error message: Access Denied
CSP Application: /csp/healthshare/hsregistry

Hello

I have noticed that Cache (2016.1 at the time of writing) doesn't come with a systemd startup script for RHEL7.

Here is a small example script I have built.

[Unit]
Description=Intersystems Cache

[Service]
Type=forking
ExecStart=/bin/bash -c '/usr/cachesys/cstart 2>&1 | logger -t cache_start'
ExecStop=/bin/bash -c '/usr/cachesys/cstop quietly 2>&1 | logger -t cache_stop'
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

The file should be placed as /usr/lib/systemd/system/cache.service

A short post for now to answer a question that came up. In post two of this series I included graphs of performance data extracted from pButtons. I was asked off-line if there is a quicker way than cut/paste to extract metrics for mgstat etc from a pButtons .html file for easy charting in Excel.

See: - Part 2 - Looking at the metrics we collected

This article contains the tutorial document for a Global Summit academy session on Text Categorization and provides a helpful starting point to learn about Text Categorization and how iKnow can help you to implement Text Categorization models. This document was originally prepared by Kerry Kirkham and Max Vershinin and should work based on the sample data provided in the SAMPLES namespace.

When running the built in Ensemble Purge task (Ens.Util.Tasks.Purge) there are three parameters DaysToKeep, BodiesToo, and KeepIntegrity. This article focuses on the KeepIntegrity boolean parameter, but more information about running this task can be found here:

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...

KeepIntegrity determines which Ensemble Messages are marked for deletion within the time specified by DaysToKeep.
