Nested set model for ObjectScript

In many projects I was faced with storing hierarchical data (tree) in classes.
By tree, I mean such data, where each node has a parent node — an object of the same class.
Many examples of such data can be given. For example, a catalog in the online store. Suppose that this online store sells books, in this case, the category tree might look like this:

CodeGolf: FizzBuzz

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”

Interface Monitoring

Hi all,

I'm looking to set up monitoring for several interfaces. I understand that I can set an Inactivity Timeout. However, obviously there are messages coming through more frequently during certain hours than other hours.

Is there a way to set an Inactivity Timeout for each hour of the day instead of one value that is used all day long?

Best,

Erin

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server. Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc. I want to do all of this from SQL Server to go with our other system monitoring solutions.

DICOM TCP IN to File Writer

Has anyone had any success receiving a DICOM TCP in, and then using a process to write to a file while responding to the sender correctly? I'm pulling my hair out, and would love to know where I'm going wrong.

Hello community,

I need to know if there is any method which can me say specified imported files or namespaces in Cache.

To better specification of my problem, I've got two installer manifests. Firts one did some resource changing and import some files and classes, second one must be started after the first one, because it's only his update, which creates some nemaspaces. So i need to check if the first manifest ran succesful and I can start the second one.

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

Distributed license use:

Current License Units Used = 1

Maximum License Units Used = 1

License Units Authorized = 200

Local license use:

Current Connections = 1 Maximum Connections = 1

Disabling an Ensemble Production

I'm not saying that this is in anyway "best practices," but I'm in a peculiar situation where I need to restrict users from starting a "retired" Ensemble Production in a namespace that's been renamed. It's still an "Ensemble-activated" namespace; we need to keep it available for Ensemble Message Viewer access ... fortunately, only for a little while.

It's a bit of a hack ...

Open the Production class in Studio and add the following classmethod:

Dynamic SQL to Dynamic Object

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.

Hello,

I've got a csp page that has successfully set up a websocket connection to a Cache class. When the websocket object's close function is triggered at the browser I was expecting one of the class' methods to fire at the server. The onclose method is triggered at the browser but nothing at the server. Is a method supposed to fire at the server?

Thanks,

Dan
