InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

InterSystems FAQ rubric

You can programmatically retrieve routine dates and sizes using the RoutineList query of the %Library.Routine (or just %Routine) class.

The RoutineList query has an argument, and the routine name to be searched can be specified by prefix match or middle match. (For wildcards, specify * or ?)

In the example below, *.MAC is specified as an argument.

I am trying to execute a program from within cache using a $zf call

S X=$ZF(-1,"C:\""Program Files (x86)""\Car-Part\Messaging\iCPM.exe")

For the sake of this post I changed it to open notepad

S X=$ZF(-1,"C:\Windows\notepad.exe")

If I call it directly from terminal notepad opens and all is happy.

If I add it to a program we use to run certain tasks once an hour or even every 10 minutes it will fire off notepad but it will be in the background.

Hi Guys

Two of the HC servers I manage (a mirrored pair) have lost the ability to debug code, and I am unsure as to why this has happened. Clearly something has changed, as the other three are working just fine.

When I select a Class Method as debug target, add a few break points and run it, I get the following Output

Hello everyone,

I just want to know if there is a difference in performance between using Class methods versus MAC routines?

For example:

do Method^MyFunction()

versus

do ##class(MyFunction).Method()

Hi All,

I am trying to disable a button on a JQM application.

I started the button as disabled according to this code: {type:'$button',caption: Button',key:'button',disabled:true}

However, I would like to enable or disable the button via JavaScript code . I have tried the following, but it don´t have the same behavior and style as the code above.

var view = zen('mainView');
view.disableItem('button',true,0);

Caché Monitor is a database\sql tool primarily for InterSystems Caché but can also connect to MS SQL Server, MS Access and more databases. Within Caché Monitors Server Navigator you see all available Namespaces on your Caché Servers. No need to know the name of the Namespace, no need to configure many many JDBC Connections by hand. Just click on the namespace and see all objects like tables, views, classes and more...

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?

New keys for Field Tests?

The FT keys InterSystems currently make available to us in the zips from the download pages are due to expire at the end of this month (31-Aug-16). Will there be new keys soon?

Also wondering when we might expect new FT builds for 2016.2 and 2016.3. The last published ones were 24-Jun-16 and 16-Jun-16 respectively.

I haven't seen an Atelier update for a while either.

Part I – Thoughts about package manager

Have you ever thought what could be a reason why some development environment (database, language) would eventually become popular? What part of this popularity could be explain as language quality? What by new and idioms approaches introduced by early language adopters? What is due to healthy ecosystem collaboration? What is due to some marketing genius?

I have a list

set list=$lb(1,$c(0),2)

How do I replace $c(0) with an empty element?

My list should look like this:

set list=$lb(1,,2)

I tried using $list but it either replaces the element with an empty string:

set $list(list,2)=""
zw list

Resulting in:

list=$lb(1,"",2)

Or removes the element altogether:

set $list(list,2,2)=""
zw list

Resulting in:

list=$lb(1,2)

$match or "?"

Hello all...

Is there two matching patterns in Caché, is there a difference in use one or the other?
Example:

USER>set a = "(1234)"

Using $match.

USER>w $match(a,"\([0-9]{4}\)")

USER>1

Using literal match (sorry if not correctly term expression)

USER>W a?1"("4n1")"

USER>1

What is different from using one or the other?

The 'a?1"("4n1")"' does this pattern exist only Caché.
Exists performance improvement with use pattern Caché?

The data model of your solution based on InterSystems platforms constantly changes over time. But what do you do with the data that was entered before? Back then, the data was valid, but what’s happening to it now after a number of data model changes? The answer to this question can be provided by the IDP DV tool that checks the property data of persistent and serial classes according to the types of these properties. In case any discrepancies are found, the tool generates a detailed error report for the user.
