Presenter: Paul Dayan
Task: Upgrade with minimal downtime
Approach: Provide examples of planning minimal-downtime upgrades from a variety of starting scenarios

When upgrading Caché, Ensemble or your application on your business-critical system, you want zero or minimum downtime. This session explores the problems and options when upgrading, and how mirroring can reduce or eliminate business disruption, with practical steps and a demonstration.

Presenter: Mark Bolinsky
Task: Decide whether a converged infrastructure is ideal for your enterprise applications
Approach: Discuss best practices and provide guidance on the right questions to ask
 

The traditional use of “SAN storage” is no longer the only choice for deploying enterprise application. Software defined data centers are making inroads into enterprise data centers, and there is good reason for it. There is the potential for significant infrastructure cost savings, architecture simplification, reduced administration costs, and depending on the configuration - even better performance. This session will discuss some best practices and outline decision guidance to help you ask the right questions when considering hyper-converged architectures.

Presenter: Murray Oldfield
Task: Avoid bottlenecks caused by scaling up, before they become a problem
Approach: Discuss what operating system and InterSystems metrics you should look at and how to interpret them
 

Systems behave differently when database activity scales up. In the worst case, bottlenecks appear and users are impacted. This session shows you which operating system and InterSystems metrics you should be looking at and how to interpret them so you can head off bottlenecks before they impact users. This sessions also shows strategies for planning infrastructure taking into consideration InterSystems' data platforms requirements.

Presenter: Stefan Wittmann
Task: Take advantage of the NoSQL paradigm without adding another tool
Approach: Provide sample use cases that are an excellent fit for InterSystems’ new document data model
 

Description: Designing applications always requires you to make assumptions about your data model. Come to this session to learn how you can effectively handle the cases where you have to rapidly evolve your model. We will also discuss other use cases that are an awesome fit for the flexible document data model.

Problem: I’ve observed the NoSQL landscape and like the direction, but I have no use-case that fits and I do not want to add yet another tool.

Solution: InterSystems now has support for a well integrated document data model that brings the NoSQL paradigm to the enterprise within your current stack.

Hello all,

I know it is perhaps too vague question, but anyway:

Do you have experience from running a thick (preferably .NET) application in any of these modes - client installed locally, Terminal Server, Citrix ? Say, there are around 300-400 concurrent users using application.

Can you share your observations / opinions?

Thank you!

The build corresponding to this release is 2015.2.3.855.0

I have existing projects in my Atelier environment.  Where can I go to see which namespace they were created in?

Hi all,

I've been looking for a way to extract the sorting  from the  ^CacheTemp.zenData global that contain the tablePane snapshot data in order to use it on a report following the current UI sorting criteria.

I could see that if the column is sorted by one column, new entries with this structure are created:

^CacheTemp.zenData(<sessionId>,<snapShotId>,<tablePaneId>,"index",<columnId>,<value>,<dataId>)=""

These are created the first time that the sort criteria is applied (asc) and has the same amount of entries as the data being displayed.

How to display or save stack information? – 12 comments

Using Class Queries - %SQL.Statement versus %Library.

This will be a stretch to be useful, but it was sorta fun.  If you just so happen to have a use case to make your HealthShare productions talk to a Slack channel, this is the Business Operation for you.

In Slack, it is a dead simple process to enable an incoming web hook:

• Name It
• Give it an Icon or Emoji
• Declare a Channel to Interact With

One you supplies those, it spits out a URL that you can go to town posting to your channel using that endpoint.

Hi!

Does anyone have an example of subj?

I know there is google service for it. Anyone uses it in production? What is the feedback?

In case of positive feedback would you please post the code example?

TIA!

Hi

I have been experimenting with the creation of a set of REST services for an app.  The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return.  However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)

How do I remove these values from the ZENproxyObject?

Is there a way to return to where you were after using the Open Declaration F3?  In studio you could use ctrl-shift-G to open the declaration and ctrl-alt-G to return.

Hello.

For debugging purposes I  sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !

The attached file contains two $system.Event examples that processes work asynchronously using persistent queues:

• Events_Simple.prj.xml
• Events_PubSub.prj.xml - updated this example has been published on https://github.com/intersystems-ib/cache-iat-pubsub

Events_Simple

This is a very basic example that creates some worker processes and then enqueue messages to them using $system.Event.

; create shared resource, create worker jobs.
USER>do ##class(IAT.S04.Event.Test).Setup()
 
; enqueue some messages to workers and see what happens
USER>do ##class(IAT.S04.Event.Test).Run()
Show log?

I am pleased to announce the field test of Caché and Ensemble 2016.2 -  an exciting new release with improvements on many different fronts.

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

Some of the more profound changes in 2016.2 include:

• Atelier - the new multi-platform IDE for Caché, Ensemble and HealthShare.

Hi -

I was looking at the “Purge Data Management” page, and one of the “Record Types” is the “I/O Log” which sometimes doesn’t clear when you purge all of the message.

But I’m not sure what it’s actually reporting as “I/O Log” messages (and I can’t find anyplace to view what is being considered I/O Logged Messages - so I can understand what’s happening)

Can anyone shed some light on these messages?

Hello,

I am experimenting with the iKnow Domain Architect in the 2016.2 field test.

I would like to know if it is possible to load metadata from text files. This was possible in previous versions, using the Loading Wizard.

I have checked the documentation and I do not see any explanation for loading metadata held in text files. Thank you!

Hello! 

We use iKnow's GetSimilar for decision making. Right now we have a domain with both good and bad documents and using GetSimilar we want to see if a document is more similar to the good ones or the bad ones. To do this we simply compare the weighted average of the score from the good ones and the bad ones that GetSimilar returns.  

The problem is that GetSimilar doesn't always return the score to all other documents. Assuming we have 50 documents I would expect the following result:

DO ##class(%iKnow.Queries.SourceAPI).GetSimilar(.

If you are waiting for the Kindle Edition of Caché and MUMPS – Part II, I must apologize. I believed what others told me that once I have a book manuscript, the Kindle manuscript will be easy. Being a programmer I should have remembered: "never assume anything." The conversion to Kindle is proving a much bigger task than I thought. But don't lose heart, I am working full time on it. I have as my goal before May 1^st. But, then again, you know what they say about goals. ;) - - Paul Mike Kadow

Hi Community: I have a legacy Caché based app that has Zlogin or %Zlogin routine. I understand that such routine will be invoked as soon as the user logs in. Can someone tell me where to find such routine? The namespace where the user connects to? Or in CACHESYS? Thanks, HT

In Atelier when resolving conflicts with the server the screen shows the Local copy and Server copy and the differences, but depending on where the difference is you cannot tell what what the document is, you need to scroll to the top to see what it is before deciding what to do.  It should indicate the class or routine name beside "Conflicting Server documents"

I believe the I have followed the instructions to attach a document to the body of a post request but nothing is being sent out in the files{} port of the request.  I can either get the stream in "data", not visible at all, or visible but no form data. Any help would be appreciated, below is what I have:

ClassMethod SendFax(phone As %String, coverpath As %String, docpath As %String) As %String
{
     Set req = ##class(%Net.HttpRequest).%New()
    //test server
    Set req.Server = "httpbin.org"
    Set req.SSLConfiguration = "CardChoice"
    
    Do req.InsertFormData("Username",##class(HData.

At the end of this year support for OpenSSL 1.0.1 will end. InterSystems has started the process to move to OpenSSL 1.0.2 and use the 1/28/2016 release (1.0.2f) for verification and product inclusion. I will update this post once InterSystems  decided which versions will receive  support for OpenSSL 1.0.2.

Stream datatypes are not displayed when you execute SQL (in SMP for example).

Learn the basics about Caché objects.

Please consider these two concepts:

Concept 1 - Web Service or Web Application or Server Side

Concept 2 - Client Service or Client Application or Client Side

Maybe I am just a Web/Zen newbie, if I am and you all understand this, I apologize. (no nasty remarks please)

The questions are numbered, if you wish to respond to an individual question please precede it by the question number.

1. Is there consistency in naming these concepts?

2. Are CSP, Caché Server Pages used for the Web Server Side only? Or both sides?
