InterSystems Caché is a multi-model DBMS and application server. See more details here.
The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.
Is there a possibility to map a CSP page residing in namespace ABC to a namespace XYZ so you could access it as if executing from XYZ: http://localhost:57772/csp/xyz/MyPage.csp ? Some odd cocktail of web application and package mappings that could make this happen?
The idea is to keep the CSP page in sort of a read-only namespace that only contains code, with the data residing in another namespace. This works for zen pages, but not for CSP.
Oracle plans to deprecate the much-maligned Java browser plugin in JDK 9. For years, the bundled plugin put users at risk with its numerous security flaws. The web is clearly moving to a plugin-free state, which is a good direction.
If you are relying on the Java browser plugin, you should take a look at Java Web Start.
Here is the official blog post by Oracle:

Hi,
I'm trying to create a Zen Report that, when rendered to PDF has a header on every page that includes some items from the group that I'm iterating over in the <body>. I can't use <header> as that only displays once for each iteration, even if that spans more than one page, but <pageheader> seems to be independent of <body> so again doesn't work.
Cheers,
Steve.
Hi
I'm starting to play around with dynamically creating tabs and panes from query data, and was trying to do the following, with nested tabs.
Tab Group
High level tabs
Sub Tab Group
Sub tabs from the High level tabs.
So I have built up my page with a placeholder top level tab group, then creating and added child tabs to this, then from this level, I have created a new Tab Group programatically, and programmatically added tabs to this new group. However, all I am getting is the top level of tabs, with all of the leaf data concatenated under it.
I'd like to have an array as a parameter for a SQL 'WHERE... IN' statement. The array would be modified in javascript on the browser. Here's a simplified example:
<tablePane width="25%" id="testTable" sql="SELECT Id from Tracking_Data.Person WHERE Id IN (?)" showQuery="true">
<parameter/>
</tablePane>
<button caption="Test" onclick="zenThis.composite.testTestTable();"/>
ClientMethod testTestTable() [ Language = javascript ]
{
var table = zenThis.composite.getChildById("testTable");
tabl
Is it possible to override JQuery Mobile elements´styles (buttons, lists, font size, color, etc) or an existing theme with a separate custom css file?
I am really interested in an official or elegant way to do it.
Thanks.
New to CSP and Zen. I've been going through tutorials and have made some progress. Using the "Contacts" tutorial as an example, I'm trying to create a "ViewContact" page. I want this to be linkable so I'm using URI Parameters, which I understand. However, what I'm not sure about is how to retrieve a specific record. Should I use a SQL statement? If so, how?
Let's say I just wanted to display the property "Name" for the contact with ID 12. What would be the best way to do so?
I created a Zen page with a header. All is good. I then created a new Zen page and during the wizard specified that it was a "subclass of a template page". So now I have Class Custom.App.HomePage Extends Custom.App.TemplateMaster. If I visit HomePage.cls I see the header from the template. However, the HomePage class has no XData Contents section so I have no idea how to actually add content. I tried adding the section but once I do then I don't see the template content anymore.
So, how do I put content in a page that extends another page as a template?
Is there someone that has developped a program in order to create a "decisiontree"? Depending The answer to a question leads to another question, and so on, and so on, and there is an option to return to another point in the decisiontree.
Best regards,
Simon.
p.s. I've already got something, but it's not workable. But to get an idea:

Often times support and sales engineers are asked about recent benchmark results on various platforms and large scale configurations. These will be made available here in the Developer Community in the "Documentation" section, and as an example here's a link to a recent Intel E7 v2 series processor benchmark.
There are several reports available and more will be made available on an on-going basis.

I am trying to define the charset for a JQM Application and it is not working. I have tried the following options without success:

Write "<meta http-equiv=Content-Type content=text/html; charset=utf-8 />"

Is there any API equivalent (within Config.Databases class, or elsewhere) that has the same functionality as the 'Recreate a database' option in the ^DATABASE routine?
This option was added to ^DATABASE (according to internal Devlog CFL1263):
to recreate a database which is equivalent to deleting the .DAT file and recreating it.
I tested this, and the recreate option also appears to also preserve the original database parameters (e.g. max size, resource name).
Is there a way to select distinct keys from an field that has a collection index? I have a field defined as follows: Property data As %Library.String(COLLATION = "EXACT", MAXLEN = "", TRUNCATE = 0); Index data On data(KEYS) [ Type = bitmap ]; And I define a build value array method that parses my data outputs an array in the format array(KEYS)=VALUES. This is very useful because I can query my data using criteria such as WHERE FOR SOME %ELEMENT(data) (%KEY='param') My question is whether there is some way to select distinct key values, e.g. SELECT DISTINCT KEYS____ FROM ____ .
Hi All,
I am trying to disable a button on a JQM application.
I started the button as disabled according to this code: {type:'$button',caption: Button',key:'button',disabled:true}
However, I would like to enable or disable the button via JavaScript code . I have tried the following, but it don´t have the same behavior and style as the code above.
var view = zen('mainView');

There seems to be little point to journal audit db updates; why rollback an audit entry for an attempted update?
I’m working on some auditing code and I have a few questions (feel free to respond regarding 2016.1 or later).
I am using &html<> to output some CSS to my page (which is a class-based and not a tag-based page), and the selectors contain the '>' character which the compiler chokes on. How can I escape the '>' so it still displays as such in the web page source but doesn't trip up the compiler?
This is for 2012.2 btw.
Hi -
If you have Cache installed on a Cent OS machine, and you want to switch the OS to Red Hat 7, and your Caché is installed on a non-OS drive, do you need to reinstall Caché?
I don't think so, but I wanted to check
The attached zip file contains a bunch of examples of Cache SQL Storage mappings that I have done over the years.
If you have existing globals and want to expose them via Objects or SQL you need to setup Cache SQL Storage mapping. If you do not see an example that helps with your case send me an example and I can help you out.

Introduction
With the maturation and wide acceptance of Java, object-oriented programming has moved to the foreground of the application development landscape. Because of their rich data models and support for productivity-enhancing concepts such as encapsulation, inheritance, and polymorphism, object technologies like Java, C++, and COM, are favored by today's application developers.
However, much of the world's data still resides in relational databases.
Introduction
Experts estimate that 85% of all data exists in unstructured formats – held in e-mails, documents (contracts, memos, clinical notes, legal briefs), social media feeds, etc. Where structured data typically accounts for quantitative facts, the more interesting and potentially more valuable expert opinions and conclusions are often hidden in these unstructured formats. And with massive volumes of text being generated at unprecedented speed, there’s very little chance this information can be made useful without some process of synthesis or automation.
Introduction
To overcome the performance limitations of traditional relational databases, applications - ranging from those running on a single machine to large, interconnected grids - often use in-memory databases to accelerate data access. While in-memory databases and caching products increase throughput, they suffer from a number of limitations including lack of support for large data sets, excessive hardware requirements, and limits on scalability.
Executive Overview
One way financial services firms can improve their operational efficiency is to revamp their data management infrastructure. Creating a central repository for data that is used by multiple applications can ensure data consistency and quality across the enterprise, ease integration bottlenecks, and lower the number of failed trades.However, different applications have different database usage patterns.
Customers who switch to Caché from relational databases report that their average performance is up to 20 time faster, running on the same hardware, with no changes to the application. What is it about Caché that lets applications run so fast?
Introduction
By now, anybody working in the technology sector will have heard of Cloud computing. But the concept is increasingly being paid attention to outside of IT departments, with growing recognition among boardlevel executives of the potential of this range of innovations. Frequently, senior personnel are hearing stories about how the Cloud helps organizations reduce costs, boost efficiency and expand their operations, so they’ll be excited about what the Cloud can do for them.
As a result, Cloud is one of the fastest-growing parts of the IT industry.
Abstract
In a recent benchmark test of an application based on InterSystems Caché, a sustainable rate of 8.9million database accesses/second, with peaks of 16.9 million database accesses/second, was achieved. These results were from a test performed on a connected system of eight applications servers, using Intel Xeon 5570 processors, and running Linux as the operating system. This benchmark shows that:
