InterSystems Caché is a multi-model DBMS and application server. See more details here.
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.
AI can be categorized in any number of ways, but here are two examples.
The first classifies AI systems as either weak AI or strong AI. Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task. Virtual personal assistants, such as Apple's Siri, are a form of weak AI.
Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities so that when presented with an unfamiliar task, it has enough intelligence to find a solution.
As you know, Caché can be used as a relational DBMS working with JDBC/ODBC drivers and supporting the execution of arbitrary SQL queries and SQL procedure calls.
We also know that Caché stores all the data in multi-dimensional sparse arrays called globals. It allows the developer not to use the standard CachéSQL engine in case a particular SQL procedure is underperforming, but instead rewrite its execution code in the Caché ObjectScript (COS) language intended for server-side business logic. This approach may help implement the optimal SQL procedure execution algorithm by using better-optimized NoSQL data structures (globals).
However, the standard class library in Caché has one limitation: for SQL procedures where data selection is controlled by custom COS code, you need to define the set of returned fields at the compilation stage - i.e. it is impossible to dynamically define metadata for an SQL procedure working with NoSQL structures. This article is about how to get around that limitation.
Hi,
I would like to list out unchecked mapped items ( classes in management portal ) classes of a particular namespace. Is there any code or terminal command which i can use ?
I am able to list out classes of namespace . But I need to list out unchecked mapped items classes
do ##class(%SYSTEM.OBJ).GetClassList(.result)
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
&SQL(
Select Name into :tName
From Sample.Person
Where SSN = :tSSN
)
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,
Sansa.
Disclaimer: This is not a how to guide and I personally do not do any of the following unless its for penetration testing. It's important to think like a hacker in order to beat them at their own game.

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 .
Hello,

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

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,
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.
In our last lesson, we added a form to Edit our existing Widgets, and save them back to the server. However, our Form was not well strcutured and our Save button had no intelligence, and was not fully visible. So today, we will apply some Material components and Angular style to make the form more useful
Let's open EditWidget.csp, and make some changes. First, we want to change the component from an md-card to an md-dialog.
Advent of Code is a series of 25 small programming challenges, created by Eric Wastl, see https://adventofcode.com/.
There are small and bigger puzzles, which you can solve typically in half an hour to a few hours. (Looking at the leaderboard, the top aces can do them in less than 10 minutes.)
It's an ideal way for beginners to start learning a computer language, and for advanced people to sharpen their programming skills.
To help you get trained for this year's challenges which start at December 1st, I will try to solve and comment the puzzles from 2016.
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
{
Parameter PATH As %String = "E:\VCS\CommandExecutor\bin\
ClassMethod Test()
{
Do $ZF(-2, ##Class(%SourceControl.
}
Now when I run the command in the Cache Terminal, as given below,
>do $ZF(-2, "E:\VCS\CommandExecutor\bin\
Recently I have been working on a performance issue reporting about that Sets or Kills in the same global performed by multiple processes in a very focused time period can sometimes take a long time (several seconds) to complete. I feel this is an interesting case study to understand about some performance tunings of Caché.
Case background:
A testing routine creates multiple processes to do set (or kill) random nodes of a global in tight loop and records the timing how long a set (or kill ) operation takes. For a global with a large number of nodes (e.g.

I was looking at the OrefToArray^%occRun in the %CSP.ErrorLog page in version 2016. However, we're on version 2014, and that method does not seem to exist yet. I would love a good way to swizzle out the info in the %request, %session, %response objects for the error log for my own error page, in version 2014. I don't want to have to go through and get all the properties manually, but I will if I must. Any other good way already written?
Thanks,
Laura
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.
{
set user = $ZUTIL(67,15,$JOB)
set status = %session.Login(username, "Test" ,1)
set log = $Get(%session.Data("Log"))
set logtype = $Get(%session.Data("logtype"))
if (log = "")
{
W !, "<div style='color:#000000; background:white; ; font-size=10pt;'><B>Your session has expired.
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.
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.
In Oracle sql Developer, you can still listing the records in a desk the use of the statistics tab when viewing a desk. there where can add, delete, edit or just viewing facts of desk currently viewd
