#Caché

Hi All, How to get the only folders (with sub-folder)from the particular drive using cache. We need to create the only folders from some drive using Cache.

Good morning, I have a ZEN application being served up through a CSPGateWay. That ZEN application is made up of two ZEN pages. One ZEN page uses a zenLink to call the other ZEN page(see below #1). The ZEN page that is called contains a tab group with one tab. That tab contains a tif image. I have components on the called ZEN page that execute JavaScript to perform simple image manipulations - zoom and rotate(see below #2). Those simple image manipulations have stopped working. If I load the called ZEN page directly AND use a fully qualified domain name, the simple image manipulations work!

Hi - Trapping onselect and onchange events that occur on layout objects seems to work fine, however, according to the documentation, I should also be able to use onevent, which is defined as follows:

onevent: Defines how the page behaves when another type of event occurs within a documentView (an event other than select or change).

I've noticed that Management portal somehow manages to allow a single user to be in different namespaces in different tabs in the same application (i.e. Management Portal).  I've looked at my Processes, however, and see that all of my processes using MgmtPortal think I'm in %SYS, even though 2 of them are looking at globals in two different namespaces; NamespaceA and NamespaceB.  

I can even fool MgmtPortal because the first time I try to look at a global in NamespaceA it thinks I'm in %SYS!  After a refresh, however, I can see the global in NamespaceA.  

How does MgmtPortal do this?

I fire a call of COS method through Java gateway and get the return value whose type is %Status in COS. What is the corresponding class for %Status in Java side? Any existing utility to help me parse this object so I could know this COS call finish with errors or not.

NewBie's Corner Session 20 Parameters and Status Part I

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

Parameters are another name for Variables when used in passing data from one Routine to another.

Let us say we have 2 routines (RtnA and RtnB), and we want to pass 3 parameters (Parm1, Parm2, Parm3) from RtnA to RtnB.

Hi All,

We are doing capacity planning. I want to track the number of rows and size of each table (or at least the top ~10). Any ideas?

Thanks

MUMPS verses Caché, what's the difference?

MUMPS was developed at Massachusetts General Hospital during the 1960s. Through a series of experiences and companies over the years eventually MUMPS evolved into Caché. Some deny this but the facts are there. You can read through the various websites with Wikipedia and make up your own mind. The closest way to explain this is that Caché is a superset of MUMPS.

MUMPS is both a programming language and a hierarchical database, that is important to remember.

Hi!

I am about to configure a server with continuous integration for a client. I found that our Russian friends have again come up to the rescue and developed not one, but two continuous integration tools for Git and Caché:

• https://github.com/intersystems-ru/CacheGitHubCI
• https://github.com/intersystems-ru/CacheUpdater

My question is simple: What are the most important differences between the two and which one is going forward so I can choose the right one?

Kind regards,

Amir Samary

Hi, I have a question about web applications.

First, I know that my ZEN application is using a web application called /OurAppName, but I honestly don't know why it's choosing that web application over the default of /csp/default-namespace, so if you can give me a hint as to how else the web application is set, please do let me know.  I'd also love to see the web application's properties programmatically, if possible (such as the physical files path).

Our other web applications are called /OurAppName/NAMESPACE rather than /csp/namespace.

Hello Fellow Cache Developers:  

Has anyone ever created an index on values of a list property?   If so, would you be willing to share an example?

Also, feel free to offer input and suggestions regarding use of indexes on List values.

I know that Cache files can be stored as XML and UDL based files. Is there any way to determine in which format the file(class, routine, dfi and so on) is stored? Because you can easily name your XML based file as class.cls and it will be perfectly valid. 

I know that one way to check whether this file is in XML format is just try to parse it like 

Set st = ##class(%XML.TextReader).ParseStream(contentStream)

if $$$ISERR(st) return $$$NO

else return $$$YES

However, is there a better way? 

Following my previous post, some urged me to get to the point – ok, so I found my "star" journaling globals, the ones that take up the most space – but how do I avoid this? How do I minimize the journal's size?

[DISCLAIMER: Some might still be disappointed after this post as well  but wait till the next one... ]

Hi all,

We have one doubt regarding cache 5.02 installation.

What is the difference b/w custom and standard installation in cache 5.02?

Thanks,

Sansa.

I want to use the Regex Matcher to strip HTML tags, but I get a REGEX error. Can anyone explain what I'm doing wrong?

set htmlSnippet = "<h1>Hello</h1>"
set regex = ##class(%Regex.Matcher).%New()
set regex.Text = htmlSnippet
set regex.Pattern = "<[^>]*>"
set plainText = regex.ReplaceAll(" ")
write !,plainText

Hello,

Has anyone encountered or done this: inherit a zen page from another custom zen page?

e.g. EditPage extends %ZEN.Component.page

///base code, some abstract methods

Property id;

UserEditPage extends EditPage

//user edit code

Property id As %String [ZENURL = "ID];

I'd like to take advantage of the inheritance and put all the common methods in the parent page EditPage, but there's no %OnNew concept for the zen page, so I can't set properties for each child page when first creating it.  

Perhaps %OnBeforeCreatePage?  %OnAfterCreatePage?

I am going to start playing with Zen Mojo (again) and as I understand it there are two ways to manage moving data to/from your Zen Mojo page:

• interacting with REST services
• using Mojo's built-in transport

I would like to understand the pros and cons of each approach.  Which is recommended in different situations and why?  I would like to create a sample application that will hopefully be reusable and helpful to others and I would like to  understand which approach to pick for my app.

Hello everyone,

I'm trying to authenticate a user(Health Share clinician) from a Java Application. 

I 'm already connected to Caché and able to run SQL commands.

My question is: How can I authenticate a user using only SQL? In fact, what I want is verify if the users exists in the base and if the given password is the same used in Health Share.

There is a column 'password' in Security.users table but I'm not able to see its content, even so, I don't know which hash function to use to compare with.

Hi, everybody
I am newbie at OSX and I am trying to install Cache on my mac

At first time I just executed in Shell Terminal next line
$ sudo /Users/Alex/Downloads/cache-2016.2.0.627.0-macx64/cinstall 
And there was no problems with instalation.
But few day after first try I've decided to update it to 2016.2.0.719.0 and I deleted previously installed version by "sudo rm -r <directory>" and only then I've tried to google "how to uninstall cache" and learned that I have had to stop instances and delete them by ccontrol first. My fault. Just in case it helps I did it
Then I.

NewBie's Corner Session 18 Caché or Cache

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Caché and Cache

Caché and Cache are not the same. Caché is a product offered by InterSystems. Whereas Cache refers to memory storage.
In computing, a cache /ˈkæʃ/ KASH, is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere.

Caché 
Spelled properly, Caché should have the acute accent (´ ) above the "e".

The FT keys InterSystems currently make available to us in the zips from the download pages are due to expire at the end of this month (31-Aug-16). Will there be new keys soon?

Also wondering when we might expect new FT builds for 2016.2 and 2016.3. The last published ones were 24-Jun-16 and 16-Jun-16 respectively.

I haven't seen an Atelier update for a while either.

InterSystems is pleased to announce that Caché and Ensemble 2016.1.2 are now available as maintenance releases.

For a complete list of the corrections in 2016.1.2, please review the release notes.

Caché and Ensemble 2016.1.2 are available for the same platforms as 2016.1.1.  The complete set of supported platforms, including specific point releases and patches, is detailed in the Supported Platforms document.

The HealthShare team will announce availability of its products separately.

The build corresponding to this release is 2016.1.2.206.0

Hi, all. I have CSP application and it needs to get and process data from ajax request with json-content. JSON can be very big. In this case: TRY { Set RequestObj = ##class(%Object).$fromJSON(%request.Content.Read()) } CATCH(Exception) { Set Status=Exception.AsStatus() } I get just part of getting JSON and validate error in $fromJSON. If I try to read it all in cycle: TRY { While (%request.Content.AtEnd = 0) { Set Data=Data_%request.Content.Read()
} Set RequestObj = ##class(%Object).$fromJSON(Data) } CATCH(Exception) { Set Status=Exception.AsStatus() } I get <MAXSTRING> error.

Let's imagine I have a global like this:

^Users(12, "SETTINGS", "IsAllowed") = 1

^Users(41, "SETTINGS", "IsAllowed") = 0

^Users(52, "SETTINGS", "IsAllowed") = 1

Now I would like to check for each user whether they are allowed, therefore I'd need to iterate through the Global. How to do that? It seems that I can't use $Order here like such:

S FF = ""
For {
 S FF=$O(^Users(FF,"SETTINGS","isAllowed"))
 Q:$L(FF)
 W "User ",FF," is allowed",!
}

Is there any other way of doing this? 

Dear Sir ,

Hi All,Now I installed the Cache 5.0 that terminal is not open can any one know the default username and password for Cache 5.0

Hello, guys.

I need to find all web files, get their content in UDL format and to be able to export them. And, vice versa, to be able to import them in udl format.

I know that they are located in CSP folder. However, is there any way to do this using COS functions?

Hello community!

Is there any method/property/way in Caché to obtain something like unique identifier for installed Caché system? The idea is to get the identifier that will differ on any other installation/machine/etc, but will forever remain the same for the current installation, even if $zv changes (in case of update) or any data is removed from the database.

Hi -

I have 3 classes: "Class A" has a property X, "Class B" has a property which is a Class A, and I have a "Class C" which has a property of a Class B.

Class A definition

Class USER.ClassA Extends %Persistent

{

Property Propx as %String;

}

Class B definition

Class USER.ClassB Extends %Persistent

{

Property Record as USER.ClassA;

}

Class C defintion (which is where I'm having my problem)

Class USER.ClassC Extends %Persistent

{

Property BRecord As USER.ClassB;

Property ARecord As USER.ClassA [ Calculated, SqlComputeCode = { ????? }, SqlComputed ];

Method ARecordGet() as USER.ClassA

{

 quit .
