Send JSON Via HTTP request

Hi Guys,

Basically I'm looking for a sample what I can send data in aJSON format to a a webservice using an http request pls?

I've found some documentation on %Net.HttpRequest but a sample on how to connect to a Webservice and send data to it would be really helpful?

Our clients are running Cache & Ensemble 2014

Thanks

I use zf(-2) to spawn a external a Java application in a *nix instance.

I would like to kill this process after some conditions met.

I would like to leverage $zf("kill ... ") but this requires its the pid of this child process.

So is there a way to acquire the pid for the child process when I create it ?

If not, how is the suggested way to kill this process?

Thanks.

This is probably a very naive question but :
Is it possible to create a Windows executable file from a Cache MUMPS (COS) routine, such that the routine can be run directly from Windows ?
If so, could some kind soul direct me to a source of information that describes the process.
I am using the free Intersystems Cache installation (CachePCkit V2017.1) on Windows 10 for my own use & personal development.

Thanks

I am using the free Intersystems Cache installation (CachePCkit V2017.1) on Windows 10 for my own use & personal development.
I am writing routines in Studio & running them in the Cache terminal TRM:3672 (TRYCACHE).
From a routine, how do I control print position within the terminal screen. I have tried using $X and $Y but this does not work and I cannot find what I need within the Cache terminal documentation.

Hope this question is not too simplistic for Members.
Any suggestion would be appreciated.

Hi, Community!

Someday you find yourself having a wonderful class package which can be helpful in several projects. So it is a library package.

How to make the classes available for different namespaces in Caché? There are two ways (at least two ways familiar to me):

1. Start the name of the package with %, like %FantasticLib.SuperClass. Wrong way.

If you do that the class would be placed in %SYS and would be available in other namespaces.

This is wrong because of the two reasons:

In %Net.SSH.Session there is a method settraceMask and that will create a wireshark cap file for help with troubleshooting a connection. I dont see any class in Net.FtpSession that can be used for troubleshooting. Is there a different method that I should use?

Caché audit & DeepSee

Apart from the database server itself, the standard bundle of the Caché DBMS includes DeepSee, a real-time business intelligence tool. DeepSee is the quickest and the simplest way of adding OLAP functionality to your Caché application.

Another standard component is an Audit subsystem with a web interface, which has the options for expanding with your own event types and an API for using in an application code.

Below is a small example of the joint use of these subsystems that answers the following questions: who did what and when in an information system?

Hi Everyone,

I am trying to reference a field, however, in our production environment, it can be found in the first second or third iteration. My code was only qualifying on the first iteration. I have been attempting to include all iterations, but I have come up short...below is a snippet of what I am attempting to use. My original code simply had GetValueAt("PID:13.4") but this only referenced the first iteration. Thanks for any thoughts!

Hi, all!
As I know, InterSystems recommends the use of Huge Pages. And if count of Huge Pages is enough, we'll see (in cconsole.log) something like this during Cache startup:

12/29/17-14:40:50:360 (3625) 0 Allocated 4630MB shared memory using Huge Pages: 4096MB global buffers, 256MB routine buffers

But if count of Huge Pages is not enough for location of all Globals and Routines caches, Cache won't use Huge Pages.

I'm referring to the document Using Cache with JDBC. Using this example, it sets the URL of the object ds of class CacheDataSource.

ds.setURL("jdbc:Cache://127.0.0.1:1972/SAMPLES");

My question is would you just copy and paste the URL from the login page to the string? I tried doing that and it returns an error saying "Invalid log file xyz"

Any help will be greatly appreciated! Thank you

Connected Data London Conference

TRIADB is an emerging unique and valuable technology in NoSQL database modelling and BI analytics. The following video is from a presentation and demonstration of TRIADB prototype implemented on top of Intersystems Cache database and driven with a CLI in Python (Jupyter-Pandas). In fact this is the second time in the past year that a prototype based on this technology is implemented and demonstrated. The first one was built on top of OrientDB multi-model database and driven by a Mathematica notebook.

Hi,

Can I get "Window Size" from terminal? By command line.

Terminal > Edit > Window Size

I already tried to use 'do CURRENT^%IS', but without success. It does not return the change, for example, when the column is 132.

Is there any routine or method for this?

What is difference between using a command $classmethod rather than just invoking them straight away?

For example if i need to call a class and its method i can just use like

do ##class(circle).radius()

rather than using

do $classmethod("circle",radius)

(I suppose both of them doing the same function i am not aware of it)

Please help me understand what is different and is there any specific usage.

Correct me if i have made mistake.

Hi everyone

How can I connect using the Terminal to a remote server?

I changed the server indication on the Healthshare icon on the Windows toolbar.

The management portal works but not the Terminal. When I open the terminal it displays only some information about the server ("SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.2"), but it doesn't give the possibility to log in.

Do you have any suggestions how I could fix it?

Thanks a lot and best regards

Milena

Let's say I have Macro.Parent class:

Include Parent
Class Macro.Parent
{

ClassMethod Test()
{
    write "Class: " _ $classname() _ $c(10,13) _ "Value: " _ $$$name
}

}

which references Parent.inc macro name:

#define name "Parent"

Now, I want in my subclass Macro.Child to have Test method with the same code, but to redefine value of name macro.
