Question Stella Ticker · Jul 7, 2017

There is a need to send a SAML token from a local cache web application to an external web application in order to grant these cache web app users access to the external web app. Is it possible to use SOAP SAML token functionality to do IDP initiated authentication with Cache acting as the IDP server? The example in this online course shows a code snippet of the service web method that adds  the token to the outbound SOAP message. So I am assuming , this would be returned to the client in response to a client request of some sort.

Configuring Java with InterSystems Technology

Regardless of what InterSystems technology you use to design your applications, it is likely that some of our product functionality will require that Java be installed on the operating system, and subsequently be configured properly with your InterSystems based application. There are many ways that this can be accomplished depending on your operating system, as well as the specific InterSystems technology you are integrating with.

Introduction

If you manage multiple Caché instances across several servers, you may want to be able to execute arbitrary code from one Caché instance on another. System administrators and technical support specialists may also want to run arbitrary code on remote Caché servers. To address these needs, I have developed a special tool called RCE.
In this article, we will discuss what are the typical ways of solving similar tasks and how RCE (Remote Code Execution) can help.

NewBie's Corner Session 14 Inline Do & Nested Do with Implied Quit and For Loop

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.

The following concepts of Inline Do, Nested Do, Implied Quit and For Loop is difficult to explain in a manner that everyone understands. However, these concepts work well with each other.

Let's create a class in Caché that will represent a teacher registry of a
University:

The name of our class will be Professor. Let's create it on
university package. To do so, make sure that your Caché
is in the Air (the small cube in your System Tray should be blue) and
right-click it, then click the
Studio, as shown in Figure 4.
When Caché Studio opens, make sure that you
is in the USER namespace. Just go to the File menu, and select the
Change Namespace option. Choose the USER namespace and press
OK.

Question Peter Kopp · Oct 11, 2016

Good morning, I am using a <Image/> tag, in a <Tab/> tag, of a <TabGroup/> to render a tif image. I would like the tif file to be rendered full size. However, I have not been able to achieve this using the height="100%"  and width="100%" parameters available. All I get is an envelope with scroll bars, with perhaps a quarter of the image visible at any one time. Thank you in advance for any and all feedback.

I need some help on navigating through the DC.

I never know where I am, what comes next, what was previous.

Do I just mindlessly go from post to post? 

A least when I use to receive email on the posts, I had some control.

Good morning, I would like to visualize the data summarized in a tablepane in a pieChart widget. Since my tablepane has already executed the query, I would like to use the tablepane snapshot as the data source for the pieChart widget. Is this possible? What would the syntax be for linking the widget to the snapshot look like? Thank you for all input.

Question Alexey Maslov · May 11, 2017

Since most of our customers moved to Cache 2015.1, I found some admins abused with CPUPct warnings (sometimes alerts) in console log without other signs of lacking CPU power.
Documentation states that:

          CPUPct               job_type              CPU usage (percent) by all processes of the listed job type in aggregate       

What does it really mean?
E.g., if total system CPU usage is 25%, and all running processes are of the same type (e.g, CSPSRV), would CPUPct be equal to 100%? If so, why this case should be a reason for alert?

Hi All 

In this article I will showcase one of my clients applications built in ZEN.  It is what I need to replace with a new UI as ZEN is no longer being developed

This application has been created for a single client who has unique business requirements - hence the bespoke development based on Caché ZEN
It is:-

  • Large(ish)
  • Supports and Implements Complex Business Processes
  • Secure
  • Multi Lingual
  • Reasonable size of development stack
