and I see in the console log a message similar to follows:
"Journaling switched to: /cache/mgr/journal/20170330.002"
Now, is there a way to programmatically find out this journal file name? In fact, I am interested to find out the journal file that is switched. For example, in the above case, that would be "20170330.001".
Hello, Thanks in advance for all replies. I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks. I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues. Now I am setting it up in lockdown mode with encryption and this one is testing me. I have everything setup but my async dr member cannot connect to the primary.
We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.
In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

I am exploring a simple restore procedure for a Cache instance and would really appreciate any help.
Basically, I have a CentOS machine with a Cache instance and let us say I backed up all the mount points where Cache data is located (install dir, DAT files, journals, WIJ etc). On another identical machine (without Cache installed), I mounted all these file systems exactly using the same mount points so all the data is back with the same paths.
In the previous article, I had just started working with Arduino, and got a meteorological station to show as a result. In this article, let's go further: we will set up authentication via RFID cards and Arduino against the InterSystems Caché application.
This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)
Inspired by the article "Declarative development in Caché" that's still trending on the dev com. The OP explored a functional style of iterating over a collection. A comment today suggested "Caché would need syntax support for anonymous functions".
With Macros you can kind of get anonymous like syntax using dot notation.
This is not production code, but it does work. First the macros...
Several years ago everyone got mad about BigData – nobody knew when smallish data will become BIGDATA, but all knows that it’s trendy and the way to go.
In the prior part of this series we have provided introduction to Google MapReduce approach, but still not covered their possible ObjectScript implementation. Which we will start to explain today.
In part I of this series we have introduced MapReduce as a generic concept, and in part II we started to approach Caché ObjectScript implementation via introducing abstract interfaces. Now we will try to provide more concrete examples of applications using MapReduce.
After a five-part series on sample iKnow applications (parts 1, 2, 3, 4, 5), let's turn to a new feature coming up in 2017.1: the iKnow REST APIs, allowing you to develop rich web and mobile applications. Where iKnow's core COS APIs already had 1:1 projections in SQL and SOAP, we're now making them available through a RESTful service as well, in which we're trying to offer more functionality and richer results with fewer buttons and less method calls. This article will take you through the API in detail, explaining the basic principles we used when defining them and exploring the most important ones to get started.
This earlier article already announced the new iKnow REST APIs that are included in the 2017.1 release, but since then we've added extensive documentation for those APIs through the OpenAPI Specification (aka Swagger), which you'll find in the current 2017.1 release candidate. Without wanting to repeat much detail on how the APIs are organised, this article will show you how you can consult that elaborate documentation easily with Swagger-UI, an open source utility that reads OpenAPI specs and uses it to generate a very helpful GUI on top of your API.
Due to a new project I'm getting involved inside %Installer stuff deeper than ever I'd be happy to. Most of it was pretty easy to get, thanks to documentation, articles and SAMPLES example, while I can't dig good solution for one problem.
Can you create ad-hoc Caché relationship objects that are not part of the original Caché class definition? One of the drawbacks with relationships is that that the more relationships you have defined, the more difficult it can be manage. I was wondering rather than having all your relationships defined in the Caché class, could you programmatically create relationships between classes as and when they are required?
This article assumes that you are familiar with Zabbix and SNMP monitoring, if not, there are some very interesting posts on the Community, especially this one (https://community.intersystems.com/post/creating-custom-snmp-oids) which contains a lot of information on how to configure and request an SNMP Cache server.
I have a 100% ZEN application combined with 100% ZENReports and am also using IFind which is part of the solution.
Our application is a cloud hosted solution where we lease a server which does not have a website, only Cache configured under IIS. Connectivity to our site is premised on a URL string such as u12345.usa-server.com/csp/namespace/Cache.cls
Given location in INT code, as Cache usually reports on error (zWriteReport+25^SomeFile.1), is there any programmatic way to determine corresponding place in original source code?
English word ="Other anemias" It is converted to french as printing "Autres anemies".But correct word is " Autres anémies".I wrote a program in the cache. But did not get the correct output.So How to solve this issue
Let's say I have two classes: A and B. They share no common parent except %SystemBase. But these classes have some properties with the same name (type may be the same or not):
Class A {
Property data As C;
Property data2;
}
Class B {
Property data As D;
Property data3;
}
I need to automatically convert object of class A into object of class B. I'm planing to write a class generator that generates a separate class that converts A to B. It would work like this:
