I have a simple callout library:

#define ZF_DLL
#include 
#include 
#undef ERROR

int GetRandom(double* random) {
   // Py_Initialize();
   // Py_Finalize();
   *random = 1.0;
   return ZF_SUCCESS;
}

int main(int argc, char **argv)
{
   printf("Random: ");
   double random=0;
   GetRandom(&random);
   printf("%lf", random);
   return 0;
}

ZFBEGIN
    ZFENTRY("GetRandom","D",GetRandom)
ZFEND

I compile this code as a shared library and it works fine with:

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.

QEWD.js is, of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript.

what is mirroring??

Dear all,

In our application made in Caché object script, when we deploy some classes modified we have the option of calling "Purge queries" feature of Caché.

We only were doing this call when a %Persistent class definition (table) was modified, as we assume that no other changes affect the cached queries and we don't want to purge them by default, as the first run of a query becomes slow.

We had a case where no table definition was changed but a purge queries was the solution.

Hello,

I'm trying to use Websockets and understand how it works. To do so, I tried to follow the sample in here :

https://github.com/intersystems-ru/WebSocketsSample

I opened studio, connected to my server into the USER namespace and use the Tools -> Import Local in order to add the 3 files (app.js.xml, index.html.xml and WebSockets.Main.cls )

I compile without error and use the View -> Web Page and it doesn't work as expected

Hello experts,

I am new to IRIS and I was told I could get a great hands-on experince with the commuity edition that is currently availabe on mutliple cloud providers.

Unfortunately connecting Atelier to the given IRIS instance has been unsuccessful:

Hi. I have the following tables

User.Order [Parent][Primary Key : Year , Month, OrderNo]

> User.OrderDetails [Child] [Primary Key : {%%PARENT}("ITM")(Running Number)]

> User.OrderDetails2[Child] [Primary Key : {%%PARENT}("ITM2")(Running Number)]

I have a persistent class that represents cities across the United States. It is below, but basically has a City Id, Name, Lat, Lon and a few other unimportant fields for this issue. Anytime I attempt to query on the Latitude or Longitude it immediately returns no results. My first thought was that it was a casting issue so I tried casting both sides to floats, ints, even strings and in all cases it immediately comes back with no results. I then decided to cast it to a string and attempt a like statement thinking it might be something about how floats are handled, but still no joy. Any

Hi guys,

I'm running a method on an instance of Cache 2010, which, when compiled, has $$$OK in it's .int code. This line throws an error, telling me that "the OK macro isn't recognized".

Some things I've tried;

- I looked it %occStatus, and the macro definition of OK is there.

- I changed $$$OK to 1 by hand in the .int code. It compiled successfully, but each time I recompile the original class, it's going to put that $$$OK back

Hi guys,

Mostly the title. Let's say my commands are stored in a text file "inFile". Here was my best guess:

<dir to iris> console IRIS2018 <inFile

For reference, here's an example of the analogous structure that works on Cache:

C:\InterSystems\Cache2018\bin\cache -s C:\InterSystems\Cache2018\mgr -U <namespace to start as> <inFile

Hi All,

I want to connect with Python pages from cache database by using Restful API's. I'm not sure which one is best method. I have mentioned below the methods. Please post your thoughts.

1) CSP Session

2) OAuth 2.0(Delegated access)

3) EWD(Enterprise web development)

Thanks in advance.

Thanks,

Arun Kumar Durairaj.

Hi,

My [Ensemble] > [Queues] page shows message queues for Operations that were deleted months ago.

When I deleted the Operations I thought Ens.Util.Tasks.Purge would cause the (empty) queues to disappear from the Queues page.

Is there a way to remove queues that no longer refer to an operation?

Kind regards,

Stephen

This is the class which I want to test.

Class GSK.MyTestUnit Extends %RegisteredObject
{

ClassMethod Add(num1 As %Integer, num2 As %Integer)
{
s res=num1+num2
q res
}
}

This is my testing class.

Class GSK.TestingClass Extends %UnitTest.TestCase
{

Method test()
{
Do $$$AssertEquals(##class(GSK.MyTestUnit).Add(3,8),41, "Test Add(2,2)=4 passed ")
do $$$AssertNotEquals(##class(GSK.MyTestUnit).Add(3,8),11,"pass/fail")
}

}
