#Caché

41

  

InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

I'm using Caché as an OAuth authorization server and I want to accept the password credentials grant type. I've found that if I make an authorize request, the Caché authorization server requires some URL parameters that shouldn't be required in password grant (redirect_uri, state, scope, and response_type). If I include these parameters, it calls my DirectLogin() method instead of just calling ValidateUser() as I would expect from the docs. I have two questions:

Client Websockets based CSP

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

Client Websockets based on Node.js

It will demonstrate the wide range that is openend by making use
of the power embedded in Node.js and its adapter to Caché, Ensemble, Health,..*
Node / JavaScript have wide reputation to work as a WebSocket client.
By using the Caché adapter it becomes easy to control it and to consume the results as a
Client for WebSocket Servers and to collect the replies in Caché, Ensemble, ..

I used node-v6.16.0-x64.msi and cache610.node as cache.node

You provide a Global for input:

Our development server is set up to automatically keep the .INT code of compiled classes and routines, but the live servers are set to not keep the .INT code.

I know how to set the system to keep this code ($SYSTEM.OBJ.SetQualifiers() ?) but what are the ramifications of keeping this code on the live servers? Is it just a space issue? I always thought it was to keep the code more private.

Hi all!
I need to call an API that has the following characteristics:

  • Content-Type: application / x-www-form-urlencoded
  • Authorization: (with a "Bearer" token)

In the body the information is given through the form data.

I can not find documentation on how to make this call and how to get the answer (JSON).

Could you help with an example?

Thank you

Hello,

I am new to InsterSystems Cache - having a SQL Server background. However I am dealing with a Third Party who use InterSystems Cache to hold some of our data. To do some analysis I need to view a backup of the database. They are prepared to send me a backup.

My question is - how can I view this backup ( would this be the CACHE.dat file?).

Do I effectively need to have an installation of CACHE on my machine to be able to view this? Is it possible to view it from SQL Server?

Any help would be appreciated.

Thanks

Colin

Hello all,

I have an XSL question and I wanted to see if someone within a community can help me out.

To Summarize: I am working with XSL documents, single and multi-pages.
Inside my style sheet XML document, which is supporting my pages, everything on the page, including a headers, footers and the items are calculated
based on the portrait measurements.
Pages come up on the screen as portrait, but sometimes, depending on dynamic data are wide, they do not print properly in portrait.

Hi All,

Can someone help me getting the security features & standards which InterSystmes Cache adheres to ISO 27001 & other security & privacy standards.

Also if you can tell me the algorithm used for database encryption & key strength by default.

This is required for a security audit.

Thanks in advance.

Problem

I'm working on exporting data from an Intersystems Cache database through the Cache ODBC Driver. There is a particular table that is giving me an error message. The ODBC Driver crashes and reports an error from the Cache system. I think I was able to trace down where the error is coming from, but I do not know how to debug or fix the error.

The table I am trying to extract is called SEDMIHP.

Here's the Error:

Hello Cache Developers: I was curious if anyone has ever created a TWAIN interface to their Cache Application? I am new to TWAIN and hence the reason for this question. From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application. I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table. Any input, sample code, or suggestions is apprec

Hello,

I am trying to copy an xml file generated on an Apache server into the Jenkins workspace post-build. I was thinking to use a 'send files over ssh' post-build script, but have not done this before and do not know how to refer to the file location on Apache server vs on Jenkins.

For example, if I want to copy from Apache's location of: "classes/UnitTest/Results.xml" into Jenkin's workspace: "/ReportFiles/Results.xml",

How does the script differentiate between whether the location address refers to the Apache server or Jenkins workspace?

Intro

Please note, this article is considered deprecated, check out the new revision over here: https://community.intersystems.com/post/tutorial-websockets

The goal of this post is to discuss working with Websockets in a Caché environment. We are going to have a quick discussion of what websockets are and then talk through an example chat application implemented on top of Websockets.

Today in docs I found this example using NULL:

 WRITE $LISTVALID($LB(NULL)),!

simplified

zzdump $LB(NULL)

and NULL can be case-insensitive:

zzdump $LB(null)

seems the same as just:

zzdump $LB()

But if null variable is defined then list would contain value from variable. Case sensitive in that situation.

Does anyone have any Idea what is this? Is NULL used anywhere besides as a list element?

Let Say I have
Class Carrier Extends %Persistent

Property Employee As Array of Class Employees

Class Employees Extends %SerialObject

Property Name As %String

Property Address As Array of Class AddressDetail

Class AddressDetail Extends %SerialObject

Property Street1 As %String

Property Street2 As %String


I can get value for Employee Name as Employee_Name.

But I want to Get Value of Address Street1 and Street2 of Class AddressDetail using SQL Query
How can I get that?

I'm finding that in a mobile app setting, that Cache is causing the worst User Experience that I have ever seen in a mobile app - I'm just saying this hoping that someone will be able to help me out, my intent is not to criticise Intersystems.

We have a Xamarin Forms mobile app that consumes web pages that are created by Cache. The app compiles into iPhone, iPad, Android Phone, Android Tablet, UWP (Windows 10, all of phone, tablet, and desktop), as well as MacOS.
