#Caché

What are the differences between a process private global and a percent variable?  Basically I have some code running in an Ensemble operation that processes requests, and it needs access to pieces of data that are scattered throughout XData blocks in various classes.

I was wondering if anyone has combined ZEN Web Development with frameworks such as W3Schools W3.CSS Framework or the popular Bootstrap Framework? 

We are currently using Caché 2013.1.6 so we do not have ZEN Mojo installed which ships in Caché 2014.2 or later.

What would be the recommended approach if looking to integrate one of these frameworks?

I look forward to hearing your suggestions!

Hi, Community!

Is there an option to get an archived file of globals in one command. Say for:

Do $System.OBJ.Export("Class1*D.GBL,Class2*D.GBL","data_gbl.xml")

get something like:

Do $System.OBJ.Export("Data*D.GBL","data_gbl.gz","gzip")

And also to have the convenient one click way to  import it to the namespace via terminal or Control Panel?

If anyone already has this module, share please?

It would be very convenient for import/export/continuous integration purposes cause globals can be really heavy.

Due to a new project I'm getting involved inside %Installer stuff deeper than ever I'd be happy to. Most of it was pretty easy to get, thanks to documentation, articles and SAMPLES example, while I can't dig good solution for one problem. I'm trying to import and compile some classes, willing to ignore two types of errors: 5202 (NothingToCompile) and 5373 (PredecessorClassDoesNotExist - a normal case when SNMP sampling class is compiled for the 1st time, before it was registered). 

I've tried the following: 

<If Condition='#{##class(%File).Exists("${AddonDir}/AddClasses.

would like to know how to execute deployments through cache terminal..Are are there any function or scripts available for deploying ? Is there any direct cache command similar to GUI-deploy that will deploy ?

Please let knoe

I have multiple namespaces in a Cache environment say NS1 & NS2. I want to add some restriction so that  a routine running in the NS1 should not access any resource(global/routine) belongs to namespace NS2.

The above restriction need for few of the clients only, so we do not want to write any custom logic in code. 

We are looking for some solution provided by Cache where we can restrict the namespace access.

Can somebody please help me on this.

Hi,

I am placing Cache instance in backup mode by using the command:

    csession <INST> -U%SYS "##Class(Backup.General).ExternalFreeze()"

and I see in the console log a message similar to follows:

"Journaling switched to: /cache/mgr/journal/20170330.002"

Now, is there a way to programmatically find out this journal file name? In fact, I am interested to find out the journal file that is switched. For example, in the above case, that would be "20170330.001".

Thanks,

Raghu

Hello,  Thanks in advance for all replies.  I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks.  I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues.  Now I am setting it up in lockdown mode with encryption and this one is testing me.  I have everything setup but my async dr member cannot connect to the primary.

Hello,

I'd like to know if there is an easy way to get result from a $ZF(-1) into a varaible to use it in HS code.

Thanks

Kindle Edition of Caché and MUMPS – Part II is released

All data is present and readable, albeit with some minor formatting issues.

Thank you for your patience in waiting for the kindle edition.

Hello,

We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS.  One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.

In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

NB. Please be advised that PKI is not intended to produce certificates for secure production systems. You should make alternate arrangements to create certificates for your productions.
NB. PKI is deprecated as of IRIS 2024.1: documentation and announcement.

In this post, I am going to detail how to set up a mirror using SSL, including generating the certificates and keys via the Public Key Infrastructure built in to Caché. The goal of this is to take you from new installations to a working mirror with SSL, including a primary, backup, and DR async member, along with a mirrored database.

Hi,

I am exploring a simple restore procedure for a Cache instance and would really appreciate any help.

Basically, I have a CentOS machine with a Cache instance and let us say I backed up all the mount points where Cache data is located (install dir, DAT files, journals, WIJ etc). On another identical machine (without Cache installed), I mounted all these file systems exactly using the same mount points so all the data is back with the same paths.

Now, if I do "ccontrol start <INST>" (ccontrol binary is from the mounted install dir), it complains that the instance cannot be found.

    In the previous article, I had just started working with Arduino, and got a meteorological station to show as a result. In this article, let's go further: we will set  up authentication via RFID cards and Arduino against the InterSystems Caché  application.

Does there exist a User Defined Language pack for Caché ObjectScript for use in Notepad++? I'm hoping some friendly developer somewhere may have created one . http://docs.notepad-plus-plus.org/index.php/User_Defined_Language_Files

Hi everyone,

I've created an Identicon Generator inspired on Fabio Gonçalves Captcha Validator.

This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)

Examples:

First one:

Will generate this:

And this:

Will generate this:

Hello us !

I want to use webservice CLS in Netbeans and use PHP development tool.

I create this

try {
    $wsdl_url = '[URL].ClassPatientServices.cls?WSDL=1&CacheUserName=[USER]&CachePassword=[PWD];
    $client = new SOAPClient($wsdl_url);
    $params = array(
        'ClsINOUTContext' => array('AccesCode'=>'CWP','username'=>''),
        'strINPatientIPP' => "91005573",
        'ClsOUTInfosPatient' => "patient",
    );
    $return = $client->GetPatientInfo($params);
    print_r($return);
} catch (Exception $e) {
    echo "Exception occured: " . $e;
}

Can you help me to use this webservice ?

Inspired by the article "Declarative development in Caché" that's still trending  on the dev com. The OP explored a functional style of iterating over a collection. A comment today suggested "Caché would need syntax support for anonymous functions".

With Macros you can kind of get anonymous like syntax using dot notation.

This is not production code, but it does work. First the macros...

#Define foreach(%c,%l) for i=1:1:%c.Size set %l=%c.GetAt(i) do
#Define map(%oc,%nc,%l) set %nc=##class(%ListOfDataTypes).%New() for i=1:1:%oc.Size set %l=%oc.

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,

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.
