Hi there,

I want to use regex in my code, and I saw that the %Regex.Matcher class contains a property "OperationLimit" that you can also set to a number of steps that the regex engine should take maximum in analysing a given string. So far so good.

I tried to set the property with the function OperationLimitSet() to a silly value like 3. In 3 steps only very few regex should be executed, right? But what I found is that my regex always comes up with a solution. Here is what I did:

First I initialised my %Regex.Matcher.

Hi Guys,

I'm getting a lot of hs_err_pid.mdmp & hs_err_pis.txt error files in the path where Cache.DAT in located and as I googled these seems to be Java error files and I'm wondering what this has to do with Ensemble, and is it alright to just delete them?

Thanks

Hello Everyone,

In October 2021 we asked for input from the IRIS community regarding exam topics for our InterSystems IRIS System Administration exam. We will close the window for providing feedback on the exam topics on Wednesday, January 12, 2022. Thus, if you would like to have your say in what topics are covered on the exam, this is your last chance!

Is there a way to add/substract from a pivot variable?

I have this MDX:

SELECT
  NON EMPTY [DateOfSale].[Actual].[YearSold].&[$variable.Year] ON 0,
  NON EMPTY [Product].[P1].[Product Name].Members ON 1
FROM [HOLEFOODS]

And with pivot variable Year equal to, say, 2016 it works:

Now I want to add previous year first with one pivot variable and one explicit reference. It also works:

Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?

I am updating a large JSON Dynamic Object. Inserting three streams using Do obj.%Set("data",pStream,"stream>base64").

Maybe I am calling Iterate() too often?

Hi,

To integrate InterSystems IRIS for Health with Open Source Drools(as rules engine), any advice? Thank you!

I made a custom application metric, imported it to the USER namespace and used:

set status = ##class(SYS.Monitor.SAM.Config).Add.ApplicationClass("historymonitor.errorSensor", "USER")

to add it. When I do 'w status' it returns 1 so it is added but I still can't see the custom metric in the api/monitor/metrics endpoint. Even though I added %DB_USER in the application roles for api/monitor.

Does anyone know where the problem might be that the metrics endpoint still doesn't show my metric?

Hi All,

I am trying to fetch resultset using the below code -

set rs = ##class(%ResultSet).%New("Simple.Person:ValidateAge")

do rs.Execute()

it is giving me error while the same code I run it through iris terminal worked fine.
I want to understand that problem behind this. Also how can I check the possible methods that I can use on 'rs' somewhat dir() does in python.

Hi,

in a Business Operation

I have a Gateway ResultSet obtained by ..Adapter.ExecuteQuery() from table A (MS SQL) which i would like to copy to table B (MS SQL).

what would be the best way to do this ?

Thanks

Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?
