Hi,

Using cube CubeA and cube CubeB that contains calculated measure TotalClients.
I would like to use TotalClient calculated measure from a compound cube CubeC (CubeA,CubeB).

How would you do that?

Hi All,

I've created a sample implementation of the MQTT protocol, which is now available on GitHub. 

The project demonstrates MQTT client capabilities and it's written in Caché Object Script.

Any comments, bug reports are welcome! Some more enhancements (like SSL / TLS support) are planned for the near future.

"Related conversations" section shows only comments number.

 In fact, these topics might also have answers.

For example, on next screenshot there are three topics in Related conversations section (on the right).

All three of them have answers, but they are shown as having 0 comments, thus seem as unanswered.

Occasionally I see a production item with a little 2 flag.  When it has that, there is an "Item" dropdown.  What does this mean?

Hello!
Are there any short ways of serializing COS entity to the string? I am searching for something like .$toJSON() , but I need Caché 2013.* support.

The one way I supposed to work is to use $listbuild:

set str = $LISTTOSTRING($LB(1,2,3,",",5))
set list = $LISTFROMSTRING(str,",")
zw list
list=$lb("1","2","3","","","5")

But the problem is that $listbuild does not escape delimiters, and it is not possible to deserialize serialized string. The structure I need to serialize may contain any characters.

Are there any short ways to do this in Caché to avoid writing custom parser?

I need to pass multiple values to a FILTER to a DeepSee DASHBOARD via the URL. The documentation seems to indicate this can be done, i.e.: "Where each filterspec is filter_name.filter_values" but there are no examples I can find that indicates what is used to separate multiple values. Say I want to pass the three values 5, 6, and 1395 to a filter. To pass just the 5 I know this works:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5

but how do I include 6 and 1395. None of the following seem to work:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5.6.1395

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5,6,139

this is catching  me all the time, again and again...

Haven't worked with XML VDOC for some time, I can't figure out, what is the correct way of using Property path. Can someone please help me to refresh my memory.

Simple example: I have a class called Body, with Value and Topic properties. I created a XML Schema for this class and imported it into Ensemble. So i have a category called message, with Body as DocType structure and Name and Topic properties of Body complex type ($2:Value and $2:Topic are element names)

My rule looks this way:

However, the rule is ALWAYS evaluated as TRUE.

Hi!

Here is small "How to" again.

Suppose you need to share something with source code. How can we manage it on DC?

Sharing code snippets

1. Add normal post (not Code Package).

2. Paste your code in the post and format it with highlighting as it is described here.

3. If you see that your COS code is highlighted wrong it means that autodetect missed with language. Open the post's HTML ("disable rich-text" button below the Editor) and put class=COS parameter into the code tag.

Example:

#dim test as %Library.Integer 
SET test = 123.099 
set ^global = %request.Content 
Write "Current date """,

Hi, Community!

If you prepare your longread for DC in Microsoft Word or Google Docs there is one very easy way how to add your formatted text and images in DC post at once.

To make it do the following:

1.Click Create Post on Developer Community.

2. Copy all the text in Word o GDocs to the buffer.

3. Click the button Paste from word (see the shot):

4. Paste the text to the opened window an press OK.

5. See the formatted text with images in your post. Save it as a draft or post it.

I've been in IT since 1986.

I started with Pr1me INFORMATION and Primos on Pr1me hardware.

In the 90s and 00s, I used D3.

I'm giving Caché a try, but I'm kinda having some difficulty getting started.

I've installed Caché on a 64-bit Windows 7 workstation. It was installed under an administrator's account. From a standard users account, I'm trying to access the Management Portal at:

http://localhost:57772/csp/sys/UtilHome.csp

It is prompting me for credentials. Which ones do I use? I've tried several, but nothing is working.

In going through the MultiValue Quick Start Tutorial, but I'm not getting

Problem: Caché instance connects periodically to an Oracle database via jdbc and downloads data. Sometimes data on a remote server would change.

In DeepSee, having a customer account cube. The cube includes a time dimension AccountCreationDate.

How do you create a calculated measure to get the total number of accounts from the beginning to a certain date in abscissa ?

I tried many things including this:
AGGREGATE(%TIMERANGE([AccountCreationDate].[H1].[MonthYear].&[190001],[AccountCreationDate].[H1].[MonthYear].CURRENTMEMBER) ,[Measures].[%Count])

But I don't get the right result because the date in abscissa creates a filter on the first date.

I tried also with %MDX function, but then I loose the context for the CURRENTMEMBER.

Hi!

There is an example in Samples which shows how to implement 'running total' measure: "Pareto Chart for Category" dashboard.

To calculate running total this pivot uses calculated measure with %Cell expression:

Hello, is there a way to reset all of the Sample Classes back to their "Installed State."? In other words, delete all the other classes I have put into the samples namespace and leave only those classes that were there when I installed the instance.?

-thank you

Hello,

We are sometimes asked for examples of how to do 3rd party SQL database selects/updates/inserts/stored procedures from an Ensemble SQL Business Operation.

In the attached file there are 4 sample Ensemble Operations that demonstrate four different types of transactions with an external SQL DB:

1:  The "CheckExists" shows how to use an Operation to do a select statement to see if a given patient MRN exists in a DB
2:  The ExecSP Operation shows how to execute a stored procedure from a BO
3:  the Update Operation does an Update
4:  the Insert Operation does an Insert

Given the samples, one can

Please add possibility to sort posts on 'updated' field.

As I understand by default posts are shown not in order of last update.

Since we have a way to see 'Unanswered' questions now, there are a couple of things that jumped out at me.  Not sure if I am missing how to do these or if they need to be added to the future enhancements list:

1) It looks like a lot of people 'Comment' on a Question rather than providing an Answer.  This means that there are many questions listed as unanswered where the answer actually lies in a Comment (but noone has submitted a formal Answer).  Is there some way to tag a Comment as the Answer?

2) In many online forums a question isn't marked as Answered until the author of the question marks

Mirroring provides an admin capability to Stop Mirroring on this member, which causes a non-primary member to temporarily disconnect from the primary, stop dejournaling, etc.  While most system administrators may never need or use this function, some employ it for certain kinds of maintenance or other special cases.

The intent is that the administrator uses the Start Mirroring function when they wish the member to reconnect.However, today mirroring also implicitly restarts (reconnects) if the Caché instance restarts.

Hello!

I have a WebSocket application which spawns new process using JOB command.

Sometimes WebSocket connection can be terminated, and in the meantime I need to hold spawned process alive until it can be associated with the new WebSocket connection. (Do not suggest serializing process state here instead please)

Technically, in Caché WebSocket connection is represented by the class, which executes in its own process. This process is terminated when the connection is lost. In this case the JOBbed process does not terminates (thanks Edward), but it rely on $ZPARENT variable.

Is it possible to hold

On June 7th we'll be releasing two new views of content that will allow you to rapidly see what's new on the site as well as identify content that has gone unanswered. The next step for this (after this release) will be to add in personalization so that you can filter content based on your tag and member "following" preferences.

Hello,

Why I don't see the full content of a XML file inside a Ens.StreamContainer Message?

When  I look into the content I only see:

<?xml version="1.0" ?><!-- type: Ens.StreamContainer  id: 5 -->
<StreamContainer><OriginalFilename>C:\Temp\In\aa.xml</OriginalFilename><Stream></Stream><Type>FC</Type></StreamContainer>

How I can see all the content? There is any setting to modify this behavior?

I am using a EnsLib.File.PassthroughService,

Hi, Community!

Last weekend we held the Final of InterSystems Contest on Caché, DeepSee and iKnow under the aegis of IT Planet Student Championship in Ekaterinburg. BTW, this year we had more than 1,400 participants in InterSystems Contest.

One of the tasks for the final was to solve T9 Spelling problem  with Caché ObjectScript and use the minimum code. 

Problem description:
The Latin alphabet contains 26 characters and telephones only have ten digits on the keypad.We would like to make it easier to write a message to your friend using a sequence of keypresses to indicate the desired characters.

When I open a Business Process in Studio I am shown a BPL diagram.

 I want to see a class definition directly.

Is there any way to achieve that behaviour in Studio?

I am pleased to announce the field test of Caché and Ensemble 2016.3 -  with many new improvements.

The product team at InterSystems looks forward to your participation in the field test and feedback over the coming months.

Some of the more signification changes in 2016.3 are new RESTful APIs for iKnow and broader APIs for programmatic control of multiple servers (enterprise manager).  As always, there are a host of scalability and performance improvements, including improvements to the core database and SQL.  And hundreds of smaller improvements and corrections.

Hi!

Sometimes, especially when I work with Combined Cubes, I need to have all the dates in Date Dimension, not only members with rows in Fact table.

Is there any way to switch it on?

Hello

During some consultant activity I did at a client's I have discovered something very interesting. It seems like the current processing cycle as written in ObjectScript has trouble utilizing an SSD-based storage machine with five-digit IOPS.

We have put a new modern and responsive UI design on top of our existing product documentation. It is available in a public beta here: http://docs.intersystems.com/beta/csp/docbook/DocBook.UI.FramePage.cls

Please review the new design and give us your feedback.
