Greetings,

If given a global, how can I discover information on that global? More specifically, how can I discover how many indices it contains? ie: ^G(1,2,3,4,5) How can I discover that there are 5 subscripts within the Global ^G if I did not already know.

Please advise, and thanks in advance for everyone's time.

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.

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

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

GlobalToJSON-Compact

I have created a package that offers a utility to load a Global into JSON object and reverse
to create a Global from this type of JSON object. Compact refers to the structure created.
Globals nodes are included with data for a fast data load.
But also the related code is quite compact.

Hi! I have a local project written on Cache and Atelier on my PC. I need to move it to notebook. Tried to export globals, classes, MAC-programms and csp with frontend stuff, but after I created my apps on notebook and imported my set, it just didn't work. I think it's because I have some settings on Management Portal, so how can I export portal settings and what I should export to have my working apps on another computer?

I'm working for an organisation that is running a very old version of InterSystems Cache (5.016) which runs on AIX . The last two times we have re-booted Cache, we have encountered rollbacks. I've been asked two questions. During the rollback it was "How long is it going to take?" and after the system returned, it was "So what caused it?". My answer to both was "I don't know".

I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global.

I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.

A confusing experience

During my last migration to IRIS I met this Compatibility parameter

  • NullSubscripts true
0 - Throw error when referencing a null subscript.
1 - Null subscript references do not throw an error.

The consequences are shocking. This was allowed:

I am inspecting our DB globals in order to reduce sizes of the worst offenders if possible. When I come to a large global, I am interested which of its nodes are the largest. Hence code below with unexpected different results. Any explanations why are results different?

I need to copy a bunch of globals from some crufty old databases to spanking clean brand new ones. GBLOCKCOPY has this cool feature that lets you create a batch of global names to copy and save the list in a batch. You can then execute the batch and go take a nap.

I like naps.

I need to do this for a number of old-new database pairs, but it's the same global names every time. Is there a way to export the batch configuration created the first time and import it to another environment/namespace? These databases will be spread across multiple hosts.

Thanks!

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?

Message data global

Hello,

We noticed from the integrity logs that some of the namespaces in our integration engine are using large amount of space ( ~380GB ) for the global ^EnsHL7.Segment.

We have culling implemented for large globals like MessageHeader and MessageBody.

Is it a standard process to implement culling for ^EnsHL7.Segment global and any idea about what will be the impact of adding culling to this global?

I found the thread that discusses object mapping, in particular mapping a common global among more than one namespace. The example that is given is a simple one when it's ^global(sub1, ^global(sub2, etc. However I'm having trouble getting this to compile/work when the global has a fixed subscript amongst variable ones.

I have this global in namespaces LAB and ARK in the following format:

^CB(1,sub1)=....

^CB(1,sub2)=...

^CB(1,sub3)=...

Here is what I have for this. In it's current state it throws tons of errors:

GlobalToJSON-Academic

I have created a package that offers a utility to load a Global into JSON object and reverse
to create a Global from this type of JSON object. Academic refers to the structure created.
Each logical node of the Global is presented separately with all its descendants.
Even if they don't contain any stored data.
