Creating and listing XData definitions

Hi InterSystems Community!

The ObjectScript language of InterSystems IRIS has the ability to extend classes using a very interesting feature called XData.

It is a section in your class that can be used to create custom definitions to be used within the class itself and also externally.

To create one or more XData definitions for your class is very easy, see the example:

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are:

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

Hello everybody.

My question originated when trying to help a coworker...

There is a system module, specifically a ClassMethod that inserts records into a table as per the pseudocode below:

set Obj = ##class(FooSchema.FooTable).%New()
set Obj.fooProp = fooValue
// Other Foo properties //
set status = Obj.%Save()

From time to time, when trying to save the object, an error , informing that it was not possible to obtain the exclusive lock on the table instance

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

Here you have an easy way to write and execute COS code from your unix scripts. This way one does not need to write routines or even open Studio or Atelier. It can be an option for simple and small actions for instance things like installation tasks or compiling.

See sample bash script (compile.sh) to compile classes:

Get STACK of another process

Hi,

How can I read the stack of another process?

I know about ^JOBEXAM, but I only know how to use through terminal, and I need to get a string, or at least do a method that returns me a string

For example:

I have process A and B

B monitors process A at each second.

B logs information about process A in a table

Informations about lock I get through %SYS.LockQuery and the process through %SYS.Process

I am reading the following code in ObjectScript:

GitHub repository

And there is a sentence which I am facing difficulties to understand:

kill ^OPNLib.Game.CWLF(..World)

I know that kill removes variables, OPNLib.Game are the package and subpackage, and ..World is a property. However what does CWLF mean?

You could think that it is the class' name, but it is:

Hi everyone.

I have a use case where I'm using embedded SQL within a Business Process to interact with a SQL table. However, when it comes to deployment into our production, the table wont form part of the deployment package created from the production.

Beyond manually creating the table on the production system, is there a standard way of ensuring that a table needed for a class is created during deployment?

I have the following problem:

  • There are several classes with method generators, which needs to be compiled during every compilation
  • I have "ckub" qualifiers enabled in studio
  • I don't want to remove "u" qualifier because I need it very much in another namespaces

So how do I force classes with method generators to recompile when "u" qualifier is present?

Awhile back the Developer community helped me with a situation I was having... How to loop through a Repeating Segment and Single Filed, example OBX().5, within a Business Process Rule and compare it against a Data Lookup table.

Well now I need to take it a step further. I need a way to loop through OBR() segment, and loop through OBR().4() and the subfield 4.1 and compare it to a Data Lookup table.

So I thought I could copy my existing function code and add another level to it, but its not returning what I would expect.
