Access namespace files

Hello, guys!

I want to get access to the folder where all files of the namespace are stored using COS. I found a way to get access to class files and found a folder where all csp, html, css etc files are stored.

However, is there any folder which contains all files(even .mac and .int)?

Or, probably, there is a method which gives all files content?

Hello,

One of our AP would like us to provide the file upload/download sample code by using ZEN Mojo.

I already provided them the attached "upload-sample".

I tried to create the "download-sample" in a similar way, but I couldn't do it yet.

Does anyone have a good idea/sample about this?

I'd like to download the server side file(e.g. c:\temp\nene.jpg) into client machine with a OpenFileDialog(image.png).

Thank you in advance.

NewBie's Corner Session 12 Do and Goto

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.

Controlling Process Flow

Controlling Process Flow means controlling the execution path of code. The execution of code flows from the top to the bottom in a routine, except for the following:

I am writing a static SOAP response to simply test connectivity. The end users is getting an error "Message: The processing instruction target matching [xX][mM][lL] is not allowed.", which I believe is related to white space. if I observe the response, it looks like there are two blank lines between the header and the body, which I'm guessing is the white space problem. But I can't seem to get rid of it.

Any ideas?

Introduction to the iKnow REST APIs

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 article provides a reference architecture as a sample for providing robust performing and highly available applications based on InterSystems Technologies that are applicable to Caché, Ensemble, HealthShare, TrakCare, and associated embedded technologies such as DeepSee, iKnow, Zen and Zen Mojo.

Azure has two different deployment models for creating and working with resources: Azure Classic and Azure Resource Manager. The information detailed in this article is based on the Azure Resource Manager model (ARM).

The Caché System Management Portal includes a robust web-based SQL query tool, but for some applications it’s more convenient to use a dedicated SQL client installed on a user’s PC.

SQuirreL SQL is a well known open source SQL client built in Java, which uses JDBC to connect to a DBMS. As such, we can configure SQuirreL to connect to Caché using the Caché JDBC driver.

2016.2 Field Test Kit 2016.2.0.677.0

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.677.0.

I haven’t sent an update to this thread in a while and it should come as no surprise that there has been quite a lot of development going on since I wrote about build 632. In fact, there have been almost 300 changes covering most areas of the product.

The accumulated list of fixes to problems found in the field since build 632 includes the following changes:

I have a MySQL server with "posts" table.

I also have a Caché server with "downloadedposts" table.

They are connected from Caché to MySQL via SQL Gateway

I want to keep Caché table synced with MySQL one (MySQL "posts" table is a master copy), so periodically Caché queries MySQL server and downloads data. So far so good, and if a record appears or changes in MySQL table, Caché downloads the changes.

The problem I'm encountering is that sometimes rows would be deleted from MySQL "posts" table.

How do I synchronize deletions?
