#Globals

Globals are multidimensional sparse arrays which are stored in InterSystems Data Platform. Everything in InterSystems Products is stored in Globals: Classes, Tables, Documents, Code.

Documentation.

I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:

import com.intersys.globals.Connection;
import com.intersys.globals.ConnectionContext;

public class Assignment {

    public static void main(String[] args) {
        Connection connection = ConnectionContext.getConnection();
        connection.connect("SAMPLES", "_SYSTEM", "SYS");
    }

}

The expection I am getting:

Hi all,

I am trying to create a method to count the number of entries in a global, including all subscripts. I am having a bit of trouble getting the code to make it to the second subscript. When I get to the position where my key is "Canada" and I add a comma and empty quotes to it, it returns USA as the new key when I do the order function. Is the $Order or the global not able to use a single string to represent multiple subscripts?

Here is my global structure:

Hi,

We have a global with 65 million entries. All we are doing is just iterating through each entry to find out the total no of entries. It is currently taking 110 minutes. Is this something normal? What can we do to speed up this process? Below is the program for just iterating each entry in the global.

s sub=" ,count=0
f{
s sub=$o(^YYY(sub)) q:sub=""
s count= count +1
}
w!, "Total Count:"_ count

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Hey InterSystems Community!

This is probably far-fetched - is there a way to get notified/get a piece of code triggered whenever the state of a global changes?

Now what could I possibly want with that? Quite simple! I would like to forward the content of a global (in this case the "FSLog" global written by the FHIR implementation) while adding timestamps to it - to create some sort of file-based logging for it.

Hello All,

I have a class method on the DocRepo server that needs to query the data value of a global variable on the Edge server.

I have looked at the documentation for 'Global Structure,' but I didn't find anything that helped.

Global Structure | Using Globals | InterSystems IRIS Data Platform 2022.1

I am able to access this global easily from the Edge server using the $Get function, but I need to access it from the DocRepo server.

We are trying to come up with huge DataStore which needs to store HIPAA transactions and Data getting partitioned with idkey - YYYYMM. Current Live data get inserted into current Month DB - HIPAA_202306. 10 years (Hipaa retention policy) old data is going to be sitting in to 120 DBs ( 201606_HIPAA, 201607... 202305) for historical audit legal compliance purposes.

Currently if we create Namespace we get 2 databases - CODEDB for routes/classes & DATADB for journals data.

We are constantly running into issues where there are billions of Orphaned messages in our system that cause problems, and we have to manually run a cleanup to fix performance issues.

In the following article about orphaned messages... https://community.intersystems.com/post/ensemble-orphaned-messages it mentions either programmatically eliminating the Orphaned messages or using a Utility like Demo.Util.CleanupSet in ENSDEMO.

Hi,

I wonder if you could help me with a problem with persistent globals and journals.

We have a few interfaces using a persistent global just to translate some codes. The use of that global is like a lookup table...an interface calls a method that search for a field (in the message) in the global. If found, the code is translated with another field from the global.

The format of the global is something like:

Class changes not executing

We are using Ensemble and I added some debug logging that writes to a global and recompiled the class in Studio. However, when we send messages, the global is not populated. I have recompiled, removing the checkmark to keep the generated code so that there is only one .INT file and I verified that the code is present in the .INT file.

My question is, do we need to stop and restart the Ensemble production in order for these changes to take effect? Do I need to stop and restart the business operation that calls this piece of code? Is there something else I may have missed?

Can someone direct me to where in the documentation we can find how consumption may be calculated for global storage?

Caché Version2010.1
Operating SystemHP OpenVMS 8.4

EDIT: After receiving some responses, it seems I was unclear in my initial inquiry. I am looking to determine our rate of consumption of storage; however, I am having some difficulty in doing that.

Hi,

I like to validate some use cases and have the following question. I am relatively new to IRIS. Perhaps someone can help:

1. I have a global m[x,y,z,f] distributed across multiple sharded instances
2. I know that i can set assign computed SQL expressions to class variables using Objectscript
3. Is there a possibility in Globals API to do the same ? Set f = x + y as a computed expression in the global m[x,y,z,f] ?

a. We would want to use the global API to change f programmatically using code

Dear experts,
Please, could you help me?

Im trying import a global:

ACB> K ^GlobalManualSend
ACB> D $System.OBJ.Load("C:\Users\BNAPC\GlobalManualSend.xml")
ACB> Set sc = ##class(%Studio.Project).InstallFromGbl("^GlobalManualSend","fv")

But is returning a error about version:

Please, could you help me about it?

Thank you.

Hi,

We are using CACHE 2017.2.1, I would like to retrieve data from Journal for killed global. Let say we have global name ^ EMP(123) with data and also have some child nodes and it has been killed by using cache kill command for some reason and we don't know who has executed this and when. My questions are below.

1) Can we get back the data of killed global from journal files,Is it possible or not ?

I am using $Query to loop through a global.

When I use $GET to get the data all we get back is the global name.

How do you get the value of the global after you have looped.

Below is my example in terminal.

Thank you in advance

Set node = $Query(^FromExtraMed(""))

w node
^FromExtraMed("A02",9220)

If i try w $GET(node) it returns

^FromExtraMed("A02",9220)

If i had this hardcoded it would have got the value
