InterSystems Developer Community is a community of 22,570 amazing developers
We're a place where InterSystems IRIS programmers learn and share, stay up-to-date, grow together and have fun!

A few months ago, I read this interesting article from MIT Technology Review, explaing how COVID-19 pandemic are issuing challenges to IT teams worldwide regarding their machine learning (ML) systems.

Such article inspire me to think about how to deal with performance issues after a ML model was deployed.

Let's say we have two serial classes, one as a property of another:

Class test.Serial Extends %SerialObject
{
Property Serial2 As test.Serial2;
}

Class test.Serial2 Extends %SerialObject
{
Property Property As %String;
}

And a persistent class, that has a property of test.Serial type:

Class test.Persistent Extends %Persistent
{

Property Datatype As %String;

Property Serial As test.Serial;

}

So it's a serial, inside a serial, inside a persistent object.

hi all,

I am looking to make a JDBC connection to my Intersystems Cache using the JDBC driver 2.0.0.

I see the connection format is as "

   jdbc:Cache://<host>:<port>/<namespace>

"

What I really want to do is filter additionally by a certain database, i.e. connect my consuming application to a database under the namespace.

how can I do that? what will be the format

Ensemble as a Data lake

We have been storing raw messages in a MySQL database for DR and ad hoc purposes. We are thinking of using an Ensemble instance as our data lake instead. We could segregate the source data by namespace or by global. But either way we'll want a custom global to index the data for data retrieval performance purposes.

Anyone else taking this approach? Any feedback?

I'd like to share with you some storage features that also exist in Caché but are almost
unknown and mostly not used. They are of course available in IRIS and gain importance
with large and distributed storage architectures.

Hi:

I have an sql outbound adapter. Sometimes we have trouble connecting to the database.

The timeout in develpment is set to 15 seconds in live it is 150 seconds as it is an always connected Buisness operation.

I thought adding E=S or/and X=S would suspend the message. Why does it not?

Is the only way around then adding something to the buisness operation itself/ creating a customised SQL buisness operation rather than EnsLib.SQL.OutboundAdapter?

Thanks

Mark

When is a number not a number?

Noticed some unexpected behavior when using $ZTH

Resultant values less than 1 are treated as strings and values >=1 are numbers. Causing heartburn in $Query / $Next / $Order loops. Is there a setting somewhere that can change this?

Example:

// Parse the time out of a text string whose format is YYYYMMDDHHMMSSsssssssss (lower case s = fractional parts)

Set MsgDT = "20180405000000001005933"
Set MsgDTH = $ZTH(($E(MsgDT,9,10)_":"_$E(MsgDT,11,12)_":"_$E(MsgDT,13,14)_"."_$E(MsgDT,15,23)),1)

//Do it again, but add a sec to the time string

I am new to Intersystems Cache, so please bear with me. We are using HealthShare 2013.1.

I have a routine to compare databases from separate instances where I want to ignore values that begin with %sqlcq. I thought this would be easy with pattern matching operator '?' but it is proving difficult and it seems to be because of the percent character.

For example:

Hi -

I'm wondering if anyone has coded up a means to create an extension for a %Persistent class from a base class to a sub-class without making a ton of assumptions about the Global structure. I'm trying to create a new "extension" record that would have the same ID as the Base Class

Class BaseRecord Extends %Persistent

and

Class SubRecord Extends BaseRecord

where I would have an instance of a "BaseRecord" and I want to turn it into a "SubRecord" instance and have all of the existing references to the BaseRecord survive.

Cache 2015.2

I need to get a sort order stored in my database with mutiple decimal places, but I want the string stored and retrieved EXACTLY as I enter it. so if someone enters 700.3000 I don't want cache to treat it as a decimal and strip the trailing zeros storing it as 700.3

once it comes back, I want the sorting to sort AS STRINGS, again, none of that stripping training/leading zeros.

this ay, I can create local arrays in exactly the order they think? they created them

Hello WRC.

Is possible to obtain a node-cache modul for the nodeJS ver.4.4.4. and actual Caché 2015... ?

And what is the expected outlook of this.

A note about this new portal: If I put into "search box" some text with dot like .js or .css ( for example: test.js ) , I obtaint error page. Try it.

Of course, this "Developer Community" is nice, the right way.

Nice day for all, Jan Krestyn

Overview

After having some discussions at Global Summit and using a lot of package managers in my day to day development (npm,nuget,Chocolatey, etc) in addition to recently using the InterSystems Package Manager for some CICD process I'm building using Intersystems IRIS and IRIS 4 Health, I wanted an easy and integrated way to search/view/install packages related to the Intersystems tech stack.

Showing dates in missing periods

When we collect temporary data (the number of purchases in the store, the number of comments on the post), it may happen that there is no data for a certain period of time. In this case, this time period (hour, day, month) is not represented in the database, that is, there is not a single row for this period. In other words, there are no rows in the database for this period.
