Several years ago everyone got mad about BigData – nobody knew when smallish data will become BIGDATA, but all knows that it’s trendy and the way to go. Time passed, BigData is not a buzz anymore (most of us missed the moment when Gartner has removed BigData term from their 2016 buzzword 2016 curve http://www.kdnuggets.com/2015/08/gartner-2015-hype-cycle-big-data-is-out-machine-learning-is-in.html), so it’s probably a good time to look back and realize what it is (what it was)…

When it becomes “BigData”?

Let’s start from the beginning: what is the moment when “not so big data” becomes BigData?

In the prior part of this series we have provided introduction to Google MapReduce approach, but still not covered their possible ObjectScript implementation. Which we will start to explain today.

In part I of this series we have introduced MapReduce as a generic concept, and in part II we started to approach Caché ObjectScript implementation via introducing abstract interfaces. Now we will try to provide more concrete examples of applications using MapReduce.

Let's say I need to process these urls in one REST method:

http://host:port/REST/arg1/arg2/arg3
http://host:port/REST/arg1/arg2/
http://host:port/REST/arg1/arg2
http://host:port/REST/arg
http://host:port/REST/

Currently I need to define URL Map like this (assuming /REST web app):

XData UrlMap
{
<Routes>
   <Route Url="/:arg1" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2/" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2/:arg3" Method="GET" Call="GET"/>
</Routes>
} 

Is there a way to get all these URLs in one route:

After a five-part series on sample iKnow applications (parts 1, 2, 3, 4, 5), let's turn to a new feature coming up in 2017.1: the iKnow REST APIs, allowing you to develop rich web and mobile applications. Where iKnow's core COS APIs already had 1:1 projections in SQL and SOAP, we're now making them available through a RESTful service as well, in which we're trying to offer more functionality and richer results with fewer buttons and less method calls. This article will take you through the API in detail, explaining the basic principles we used when defining them and exploring the most important ones to get started.

This earlier article already announced the new iKnow REST APIs that are included in the 2017.1 release, but since then we've added extensive documentation for those APIs through the OpenAPI Specification (aka Swagger), which you'll find in the current 2017.1 release candidate. Without wanting to repeat much detail on how the APIs are organised, this article will show you how you can consult that elaborate documentation easily with Swagger-UI, an open source utility that reads OpenAPI specs and uses it to generate a very helpful GUI on top of your API.

Can you create ad-hoc Caché relationship objects that are not part of the original Caché class definition?One of the drawbacks with relationships is that that the more relationships you have defined, the more difficult it can be manage.I was wondering rather than having all your relationships defined in the Caché class, could you programmatically create relationships between classes as and when they are required?We mostly use parent-child relationships in our classes.

Hi, Community!

Here are some news on Developer Community enhancements.

In March we fixed a lot of bugs and rearranged the notification system, so I hope you'll be happy with it now.

I'm pretty new to Ensemble and Cache, and I ran into an error today that I haven't seen before: "ErrNoResponseClass: No Response Classname is assigned for Request class <<someNumber>>". I haven't found much documentation about this beyond the Ensemble Error Codes document, which is essentially just a duplicate of the information I can see in the error message when this problem occurs. Is there any further information about this error and the conditions that cause it? Or perhaps what the <<someNumber>> value represents?

From what I can tell, the response class is set by the base class of my

Hello,

i'd like to create a directory chain with  "EnsLib.FTP.OutboundAdapter"

i'm using it like that with the class file and it's working:

s file = ##class(%File).CreateDirectoryChain(directory)

But now i'd like to create a directory chain with the FTP Outbound but i don't know how , i didn't see a method to do that.

Thanks in advance.

Hi,

I have a xml stored in a globalCharrachter Stream.

I would like to get a full node parts of the xml to store it in an other file.

Exemple of an Xml store in cache

<doc>
<header></header>
<product></header>
<market></marker>
<doc>
</aaa>

I would like to generate new xml from this one like

<product></product> to product.xml

<market></market> to market.xml

s xml = ##class(MyExemple.test).%OpenId(1) --> my object with XML <doc> store 
s doc = ##class(%XML.Document).%New()
d doc.GetDocumentFromStream(xml.TXML)

Dear InterSystems Community! Do you control your Caché or Caché controls you?

Recently, I decided to start the project about control of Caché instance. The control is based on communication with chat bot.

For example, below text message shows current statistics of the certain Cache instance.

/stat <cache-instance>

Another example (start the certain Caché instance).

/start <cache-instance>

One more example (stop the certain Caché instance).

/stop <cache-instance>

What do you think about the project? What do you think about additional functionality?

Please, feel free to share your thoughts.

Hi Community,

This article assumes that you are familiar with Zabbix and SNMP monitoring, if not, there are some very interesting posts on the Community, especially this one (https://community.intersystems.com/post/creating-custom-snmp-oids) which contains a lot of information on how to configure and request an SNMP Cache server.  

With Cache, all MIB data objects are organized into tables, so you need to know the index of an object to be able to get its value.

I have a 100% ZEN application combined with 100% ZENReports and am also using IFind which is part of the solution.

 Our application is a cloud hosted solution where we lease a server which does not have a website, only  Cache configured under IIS.  Connectivity to our site is premised on a URL string such as  u12345.usa-server.com/csp/namespace/Cache.cls

With the release of Firefox V52 this connection string is now seen as security threat as we have an application login page using  two <password> controls.

GT1|1|1|Test^Test||123 Building^123 Building^Brooklyn^NY^11220^United States^^^Kings|^PRN^PH^^^^^^^^^(111) 111-1111~^PRN^CP^^^^^^^^^(222) 222-2222|||""|IN|DGH^Daughter

I'm trying to clear the phone number completely.

Remove target.{GT1(1):GuarantorPhNumHome()} still gives me _~_

Given location in INT code, as Cache usually reports on error (zWriteReport+25^SomeFile.1), is there any programmatic way to determine corresponding place in original source code?

I discovered a possible error in one of the courses but unlike other learning platforms, it isn't obvious how to report it.

Hi All,

    We using cache 5.02.We have some problem regarding license usage.

I just clicked on the link "Contribute feedback about this site" and was brought to the feedback group

https://community.intersystems.com/group/developer-community-feedback

However all the issues that have been logged are now  gone.   Were they all fixed?

All that is there  is some year old posts about winning a pass to global summit 2016.  They should not be in this feedback group.

Also the button to "create a new post" is gone from this page.

I wonder if this post will appear in the feedback group?

Goal:

• Take an HL7 message, parse some data from it
• Call a web service to get an authorization key, comes back as a simple string
• Create a request object with data from the HL7 message and send it to the Web Service

The main web method call requires that key I received as a Soap Header element. All I can pass to the SOAP Operation business class is the request object with the data I plucked from the HL7 payload. Nothing in that particular request message has anything in it that tells anything to send the header, too.

So what are my options to pass a message to the SOAP Operation that contains both

I have a number of Business Process and due to the complexity these were created as "custom code" instead of BPL.

These processes currently invoke other components using SendRequestSync. For a couple of reasons I would like to be able to change these to use SendRequestAsync:

• a long running BusinessOperation (often over 45s) calling an external system has caused pool sizes to be increased to compensate. This operation is a real time request for the entire health record held for a patient.
• with the above operation, a different webservice method can be called that allows partial health record to be

Hi,

      English word ="Other anemias" It is converted to french as printing "Autres anemies".But correct word is " Autres anémies".I wrote a program in the cache. But did not get the correct output.So How to solve this issue

Let's say I have two classes: A and B. They share no common parent except %SystemBase. But these classes have some properties with the same name (type may be the same or not):

Class A {

Property data As C;

Property data2;

}

Class B {

Property data As D;

Property data3;

}

I need to automatically convert  object of class A into object of class B. I'm planing to write a class generator that generates a separate class that converts A to B.  It would work like this:

1. Query %Dictionary to get list of properties:

• With the same names
• With both properties being of datatype or object type

2

Currently, we have an application running in one namespace ("Database B") that has globals and routines mapped to another database ("Database A"). After enforcing clean up on Database A, we found that 90% of the disk is free. We would like to compact Database A and release the unused space. However, we are running OpenVMS, which seems to be the issue.

For databases consisting of only globals, we are able to use ^GBLOCKCOPY; however, we need to ensure that the routines and mappings are also copied.

What would be the best recommended way to do this?

Hy.

Is there a way to migrate MySql db to Cache (like export from MySql and import to Cache - not just the data, but the properties of the table too)?

Thank you.

Hi,

I was wondering if we have some documentation and sample code how to create APNS and GCM using Caché ObjectScript.

Thanks

Has anyone done an ebXML implementation using the out of the box classes?

I would like to hear about your experience and any issues you encountered using the classes provided.

I have been asked to assist in the planning of the a new server for our database, which we will be changing operating systems from OpenVMS to Linux (RedHat distribution). However, its difficult to find material regarding what would be recommended, which is likely due to the database being proprietary.

In looking at the information provided below and hoping to decrease processing time, would anyone be able to recommend type of configuration we should have for the new Linux server? Please feel free to ask any clarifying questions.

The current server is running with the following hardware
