Can you keep a secret?

If you are developing applications that use CSP or Zen, or potentially any of the other InterSystems web-related stuff that's built on top of CSP, then it's important to know how to keep one particular secret.

A central part of the CSP security architecture is a server-side session key. "Server-side" because its value should never be revealed to the client that is issuing the web requests. If it is revealed, a malicious client might be able to use it to bypass your security and make your server do things you don't want it to.

Hi, guys,

One of my clients was required by the hospital to name their webservice operation as Action_Subject, ie. Get_PatientInfo

When I define the web method as "Get_PatientInfo" as below,

/// MyApp.MyService
Class MyApp.MyService Extends %SOAP.WebService [ ProcedureBlock ]
{

/// Name of the WebService.
Parameter SERVICENAME = "MyService";

/// TODO: change this to actual SOAP namespace.
/// SOAP Namespace for the WebService
Parameter NAMESPACE = "http://tempuri.org";

This is a translation of the following article. Thanks [@Evgeny Shvarov] for the help in translation.

This post is also available on Habrahabrru.

The post was inspired by this Habrahabr article: Interval-associative arrayru→en.

Since the original implementation relies on Python slices, the Caché public may find the following article useful: Everything you wanted to know about slicesru→en.

Note: Please note that the exact functional equivalent of Python slices has never been implemented in Caché, since this functionality has never been required.

And, of course, some theory: Interval treeru→en.

All right, let’s cut to the chase and take a look at some examples.

NewBie's Corner Session 17 New command

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

New command

The New command limits a variable's scope or range of use. In theory the New command is simple, in reality the New command is powerful and needs to be respected and understood. In Caché ObjectScript and MUMPS an entire chapter is devoted to it.

There are three variations of the New command:

When used without variables

Introduction

A REST API (Representational State Transfer) is an interface that allows different applications to communicate with each other through the HTTP protocol, using standard operations such as GET, POST, PUT, and DELETE. REST APIs are widely used in software development to expose services accessible by other applications, enabling integration between different systems.

Have you ever thought about leveraging IIS (Internet Information Services for Windows) to improve performance and security for your Caché web applications?
Are you worried about the complexity of properly setting up IIS?

See the webinar Configuring a Web Server presented by @Kyle.Baxter, InterSystems Senior Support Specialist. Learn how to install IIS, set up it up to work with the CSP Gateway, and configure the CSP Gateway to talk to Caché.

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

While I love using VSCode for IRIS development work, one of the persistent frustrations with it has been the inability to display an object hierarch in the variables window while debugging. Only the object's reference identifier is displayed. Cache Studio's handling of the same issue is a little clunky, but it does at least have the option to display something as an object.

For now, I make do with a combination of the watch window and the command line in the debugging console -- but this feels just a step away from log.debug()/console.log() level debugging sometimes.

Hi Community,

I have a need to access the Lock Table to find the Process ID of the process that has a particular global node Locked. The process holding the lock could be on any one of four application servers.

Having identified the Process ID, I then need to interrogate the local variables for that process, to find an application User ID.

I can then inform the current user which of their colleagues has a particular record locked, preventing them from continuing with their work...

Are these things I can do under Caché? If so, how would I do so?

With the advent of Embedded Python, a myriad of use cases are now possible from within IRIS directly using Python libraries for more complex operations. One such operation is the use of natural language processing tools such as textual similarity comparison.
