#Caché

Is there any simple code in Cache using FHIR to understand the relationship between them? If so can anyone provide some example.

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.

Embedded SQL is a tool that allows us to execute SQL statements in Caché Object Script. For example, to select the name of a person with a particular SSN from the Sample.Person class

The colon syntax is used to identify local variables, in this case tName and tSSN. &SQL indicates to our compiler that this is SQL syntax. At compile time, this statement will be optimized to executable Object Script code. More about this syntax can be found here.

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.

Hi All,

         How to export the cache user account in cache 5.02?

         How to import the cache user account in cache 12?

Thanks,

Hello,

I have a problem when i take the adapter: EnsLib.FTP.OutboundAdapter. 

I want to write a file, but if the file already exist using the method ..Adapter.PutStream(name,file) and in my setting "overwrite" is true. FTP response me this message:

Overview

The The System Monitor Dashboard project is, most generally, an open source extension to the Cache System Monitor.

More specifically, it allows users to customize the monitoring of a Cache environment as well as how the collected data is visualized.

Goals

• Displays important system state and historical information in an accessible and useful way.
• To provide an intuitive and complete API for users to tailor the Cache System monitoring to their specific needs.

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.

Question

 What version of Caché supports TLS v1.2? 

Answer

Caché uses the openssl library for SSL/TLS support.  On Windows, Linux and Unix, a version of this library is included with the install kit.  Caché 2014.1.3 and 2015.1.0 ship with the openssl 1.0.1j library.  TLS v1.1 and v1.2 support is first available in openssl version 1.0.1, so Caché 2014.1.3 and 2015.1.0 are the first versions to allow the use of TLS v1.1 and v1.2.

On these versions, if the "TLS v1" checkbox is checked in an SSL/TLS configuration, the system will use any of TLS v1.0, v1.1 and v1.2 .

Hi all,

       In Cache 5.02 while creating user the password was encrypted.

      how to decrypt the password in cache 5.02?

       We upgrade the cache 5.02 to cache 2016 ,But the user accuonut  are not updated in cache 16.

      We have created user acconut in login global in "%SYS" namespace .But the password are encrypt.

Thanks,

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.

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:

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

NewBie's Corner Session 10, Subject: Routines and Studio

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.

InterSystems has a new IDE called Atelier but that is for later.

A Routine is the name that Caché calls computer programs. A Routine consists of a number of lines of instructions to the computer; these instructions are called code.

Hi,

I try to programmatically create a parameter for a dataCombo ZEN Component (which is in turn created on the server side at runtime).

Set tParm = ##class(%ZEN.Auxiliary.parameter).%New()
Set tParm.id = "pRegion#"_pExamContainerCount, tParm.name = "pRegion#"_pExamContainerCount

Set tExam = ##class(%ZEN.Component.dataCombo).%New()
Set tExam.id = "Exam#"_pExamContainerCount, tExam.label = "Untersuchung", tExam.queryClass = "Inventory.ServiceCatalog", tExam.queryName = "QGetExaminations", tExam.showEmpty = "false", tExam.size = "52", tExam.onchange = "zenPage.updateExamDescription(zenThis.

Hello,

I have some code that reads an %XML.DataSet object that gets returned from a web service. I'd like to unit test this code by importing an XML data set from a test file. How can I do this?

I created the test file by calling WriteXML on the data set, and copying the output into the file:

I tried to import the file using the XML reader, but the resulting data set doesn't have any rows:

In this article I will show you how to build Universal JavaScript  applications using Caché (sharing your code across front- and back-end). But before we start writing code, I'll first give you some reasons and background why you should consider building your applications using this technology.

As I described in an earlier article on my CODE development blog, applications need to run these days on all kinds of devices and operating systems with different form factors and application development requires a new strategy. One can't keep using platform specific development tools anymore.

Hi,

Thanks a million for taking the time to read this.

I'm calling the functions $ZF(-`1, <path to EXE>) and $ZF(-2, <path to EXE>) from Cache code. The exact code I'm using in Cache Studio is given below.

/// Test the functionality of ZF(-1) and $ZF(-2), 
Class %SourceControl.UnitTest Extends %Persistent
{
Parameter PATH As %String = "E:\VCS\CommandExecutor\bin\Debug\WindowsApplication.exe";
ClassMethod Test()
{
Do $ZF(-2, ##Class(%SourceControl.UnitTest).#PATH)
}

Now when I run the command in the Cache Terminal, as given below,

>do $ZF(-2, "E:\VCS\CommandExecutor\bin\Debug\WindowsApplication.

Is there any simple code in Cache using FHIR to understand the relationship between them? If so can anyone provide some example.

One of the internal changes in Cache 2016.2 is the switch from using Posix asynchronous IO on Linux platforms to native kernel asynchronous IO for improved performance. There is a kernel parameter that controls the maximum number of events that can be handled across the entire system and it is possible to hit this limit on newer versions of the Linux kernel when Cache is setting up disk IO structures in the WD or user processes. To prevent this from occurring we recommend that the kernel parameter

Hi ,

     The below code is working in cache 5.02 but it'snot working cache 16.

      while we calling this method in another csp page it's show some different character.

      ClassMethod OnHTTPHeader(ByRef OutputBody As %Library.Boolean) As %Status [ ServerOnly = 1 ]
  {
set user = $ZUTIL(67,15,$JOB)

set log = $Get(%session.Data("Log")) 
set logtype = $Get(%session.Data("logtype")) 
if (log = "")

Overview

Current Caché system monitoring functionality provides real-time information about a Caché environment. This allows for preventative measures to be taken before system failure by highlighting specific metrics when they are at unusual or dangerous values. Additionally, diagnosis of past or current erronious events is aided by informative logs that are created by the system monitoring process.

The System Monitor Dashboard project is a successor to the current system monitoring functionality.

Hi,

I've managed to get a zen Report working where it outputs the contents to a pdf file - the pdf has a background image and it works perfectly. I now want to print that PDF from Caché.

I've tried to use the GenerateReport method - mode 12 — Generate a report in PDF format, and send it directly to a printer via the Caché Print Server e.g. s sc=rep.GenerateReport("Printdoc.pdf",12)   (where "rep" is my zen report)

I've created the Caché print server in the management protal as per the documentation.

I don't understand where I need to specify the printer that I want to use.

For those who are interested, or want to do something different with the cache language, I leave here two codes of animations.

They serve to run on the terminal while executing a routine, or a method.

To escape the monotony of seeing that static code in the terminal.

The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…

This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.
