Someone posted a question on DC asking whether it was possible to determine access rights for a particular table row always at runtime, and if it was, how could one do that?
Answer: it is possible and it’s not hard at all.

Here's my issue. I've been using Sample.* globals and packages mapped to another development namespace to realize unit tests. So when I ran it, I notice that I forgot to start a transaction in order to be able rollback it to it's original data.
I assumed that I should use transactions since I was manipulating it's data but I didn't want it to be persisted.

Unless I'm mistaken, 2017.1 doesn't appear to support RFC 7523 (JSON Web Token Profile for OAuth 2.0 Client Authentication and Authorization Grants).  Is that coming in 2017.2?

In order to support it in 2017.1, I'd have to override the OAuth 2.0 token endpoint to cater for the additional grant types - what's the best way to do this?

Thanks.

I know the process ID< and I know the global name: ^||testing(index).  From the terminal (and therefore, and different process ID), how do I view the contents of ^||testing() ?  Not the list of process private globals; the contents of this single PPG.

Thanks,

Laura

Good day InterSystems Community,

Could someone share ready to use Zabbix monitoring templates for InterSystems Cache? SNMP OIDs, etc..

Hi, Community!

Suppose I have class A with properties P1 and P2.

I want to introduce class B, which would have same records as Class A, but only  one property - P2.

What is the easiest  way to manage it assuming that I would like to use Class A to add records and be available for any operations to Users with Role A.

And I would like to introduce class B for Users with role B for read-only access.  Preferably they shouldn't even be aware of Class A and P1 existence .

What is the easiest way to introduce it and manage it?

Use some proxy-classes?  Property-level security?

How to simply going to get the value of the system language from ^%z?  Because  I got a problem, U2 context isn't setup while connecting the SQL Connect.

Hi!

In the below code for cls with csp i have passed the output to a global but after i give the content in the text box it is getting stored, but when i check the global it is empty.

My oldest release is 2013 on this computer.

Does anyone know how far back $system.Version.GetMajor() goes.

I needed to use the OnGetNodeInfo callback of a Zen <dynaTree>, because this seems to be the only way to control the style separately for different levels of the tree. This post describes two discoveries I made.

How a dynaTree builds a tree via the OnGetNodeInfo callback

When you use a dynaTree with the OnGetNodeInfo callback, the dynaTree creates a series of nodes and displays them top to bottom in the order they were created. 

What is COS Expression? Is the related to SQL Expression?

Can you give a basic code or query related samples? If anyone give a sample, it's understanding easily.

Hello experts,

I’m working on an "Sort After" (]]) bug that I traced back to some weird behavior in ObjectScript.  Perhaps someone can enlighten me…

The problem is as follows:

Let’s say we have:

Set A = “1.0”
Set B = “2.2”

If you execute the command ‘Sort After’ (]]), you get the following:

W A]]B
​1

…Which is wrong, A does NOT sort after B.  The output should be 0.

If you set A and B to numeric values, it correctly outputs false (0):

set A = 1.0
set B = 2.2
​W A]]B

0

The Cogs.JsonClass library is now available in the Cogs project on GitHub.

https://github.com/SeanConnelly/Cogs

Please see the README and the /docs folder on how to use the class.

Overview

The Cogs.JsonClass class provides a one step serialisation and deserialisation to and from Caché registered and persistent classes. It is not dependent on any other code and should be compatible with older versions of Caché.

The unit tests have been included in the update, but until I release the dependent Touchstone unit test solution it won't be possible to run these tests.

Hi people,

I am migration my web application of Cache 2013 to Cache 2016, in Cache 2013 I have a integration with a Java aplication using Java Gateway mapping proxy classes and consuming a method that param is a object, and it works perfectly.

But in Cache 2016 this integration don't work, I send the param as object but Cache send as String with the ref of object...

I maked a test, importing two classes used by the Java Gateway (%Net.Remote.Proxy and %Net.Remote.Gateway) of the Cache 2013 to Cache 2016 and integration come back it to works, but I don't see significant changes to justify.

Set dynaform property  layout="horizontal" makes form controls to be shown horizontal in one row.

But how configure dynaform to show controls in several horizontal rows?

Hi,

I'm unable to locate a set of instructions that would allow me to encrypt the traffic to/from the Cache' Management Portal (that is - run it over HTTPS)

I am referring to the Management portal as hosted by the private Apache Web server instance installed with Cache. (I know how to do this for regular web sites hosted on, for example, IIS).

I would imagine the steps would involve, (a) enable SSL on that apache instance and (b) deploy certificates into the Apache web server.

Does anyone have a step-by-step guide on how this is accomplished ?

Thanks in advance - 

Steve

We have a service that sends XML message. During unit test, I tried to resend the message with following scenario:

(1) If I leave the content blank, the original message will be resent in the ContentStream;

(2) If I post a new XML message, the new XML will be sent in the Content, the original message will be resent in the ContentStream;

(3) If I post a new XML message with very big length, it will be converted to 5@%CSP.CharacterStream, and following kind of error will be thrown:

Hi all,

     Is there any way to add more systems defined widgets into the ZEN components ?

     Thanks in advance.

Thanks,

I have a tablePane that always displays with the bottom row selected. The SQL is executed when the submit/search button is clicked.  See attached.

Does anyone know how to enable row selection but prevent the bottom row being selected after the button onClick event?

In iknow they are mentioning that Japanese words cannot be used for iknow in CRC and in CC, If one needs to use iknow for Japanese character how does concepts and relation works for them?

Hello everyone,

I'm doing a REST service for integration between 2 systems. The system that invokes me expects a response object where only one of its attributes changes. It could be something like this:

Class ResponseCustomer  {
    Property Code As %String;
    Property Info As Customer;
}

Class ResponseAppointment {
    Property Code As %String;
    Property Info As Appointment;
}

Class ResponseCancellation  {
​    Property Code As %String;
    Property Info As %String;
}

In our last lesson, we implemented a linkage to our WidgetAccessory class, and debugged some errors we encountered along the way.  We now have our data being returned by REST, but what if we want to update or add new data to our application?  

or "Things are going to break"

We left our application over the weekend, secure in the knowledge that it was returning data from our primary persistent class, User.Widget.  However, Widgets Direct are the premier supplier of both Widgets AND Widget Accessories, so we should really start working on adding these Accessories to our application. 

Hi,

In SOAP Wizard, whatever WSDL I pass, I m getting the following error in the SOAP Response. Even If I create my own SOAP Web-Service and pass its WSDL, I am getting the same.

I'm breaking my head trying to figure how to solve this issue. 

I need to guarantee that a parent AND child rows has been inserted successfully before any other process is able to read ANY of the data.

What is the proper way to prevent DIRTY reads?  Per the InterSystems's documentation I should be able to use 'START TRANSACTION ISOLATION LEVEL READ COMMITTED'.  I have attempted to use these commands in embedded and dynamic SQL calls to no avail.

I have to be able to insert the data via JDBC calls, but legacy Caché (.MAC) may be reading the data, and if the data is read to quickly, I could have processing errors, as all the child rows have not been inserted.

Hi!

I have a question:

I create a Operation REST API , when I call to my client trough this REST API, my cliente returns list of object in JSON, like that:

[
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    },
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    },
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    }
]

On the other hand, I have in my Ensemble, Two class:

During a Caché system management training course today we discussed structural database integrity (a.k.a. physical integrity) and the tools InterSystems provides for checking integrity and fixing problems.
