If you've worked with iKnow domain definitions, you know they allow you to easily define multiple data locations iKnow needs to fetch its data from when building a domain. If you've worked with DeepSee cube definitions, you'll know how they tie your cube to a source table and allow you to not just build your cube, but also synchronize it, only updating the facts that actually changed since the last time you built or synced the cube. As iKnow also supports loading from non-table data sources like files, globals and RSS feeds, the same tight synchronization link doesn't come out of the box. In this article, we'll explore two approaches for modelling DeepSee-like synchronization from table data locations using callbacks and other features of the iKnow domain definition infrastructure.

Is there a way to do this? I found the way to store .gz files, but .zip files are different.

Hello,

I work with trigger and I need afeter update make INSERT into LogTable value of prorerty of saved class. This is what i have in this monent.

S className = ..%ClassName(1)
S cls=##class(%Dictionary.CompiledClass).%OpenId(className)
F i = 1:1:cls.Properties.Count() {
S prop = cls.Properties.GetAt(i)
S propName = prop.Name
S value={propName*N}
}

How Can I get value given "prop".

On the back of my recent post on writing bug-less code I wanted to raise a few suggestions (to ISC) that would help prevent certain types of bugs at compile time. I've probably missed a few, but these are the main ones in my mind. Please contribute more suggestions.

Btw, these also serve as potential gotchas for new COS developers.

I only recently noticed the presence of a local database named CACHE alongside the more familiar CACHESYS, CACHELIB, CACHETEMP and CACHEAUDIT.

A bit of digging through the documentation archive led me to conclude that the CACHE database arrived in 2010.2, where the release notes say:

Hi all,

I was wondering if InterSystems offers any message profiling capabilities. What I mean by "message profiling" is essentially stats or metrics gathered from a collection of data submissions of a particular type. For instance, average number of segments <XYZ> in a specific HL7 V2 message type. Or the number of sections found in a HL7 V3 CDA documents.

Curious if there is anything like this provided "out-of-box".

Thanks!

In this recent post I highlighted the importance of a CSP session's Key property in enforcing the level of security your web application may be relying on, and in particular the need to keep the property value secret.

Is it possible to export PRJ file without section BreakPoints and Target attribute? /diffexport does't help.

They just make noise when pushing into GIT

I have classes A and B, B derived from A, A has method Abc.

From INT of class B I see that compiler copies implementation of Abc to class B, so that Abc exists both in A and B.

As result, when B invokes Abs, B.Abs() is executed instead of A.Abs(). In result debuger is not able to step into Abs and breakpoints in A.Abs never hit.

Why this happens and how can I avoid this?

Update:

OK, now I know the reason: compiler makes the copy if Abc has this line:

Hi, Community!

There is a large file that needs to be processed, with over 500 000 rows. Each row needs to be verified for various data and then all the results collated and reported into a single report. What is the most efficient way to do this? I tried calling the processing function with Job , where each function jobbed off would report results to a different node of a common global. But the jobbed functions are not updating their respective rows even though I am passing the global name and root node. What is the most efficient way to process this large file?
