#Caché

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 happensUSER>do ##class(IAT.S04.Event.Test).Run()Show log? no/[yes]:^

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.
• Introduction of a DOCUMENT data model (extending the reach of our multi-model capabilities)
• Concurrent management and configuration of many servers

As always, there are a host of scalability and performance

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(.sim,domId,id,1,200,"",$$$SIMSRCSIMPLE, $LB("ent"))

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

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

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).

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?

3. The InterSystems documentation, Securing Caché Web Services, used for the Web Server side

Whichever way you want to look at it, their numbers are impressive... growing revenue year-on-year of 69% is amazing... and now they are opening DCs in Canada and India...

Do you use any public cloud? Any private one?

An XML-enabled class has an XMLExport() method that knows how to serialize an instance to XML. To export all instances of a class to a file, I need to instantiate a writer and loop through the extent. Is there no class method like XMLExportToFile() that does this in one go?

I am happy to announce the immediate availability of  Caché and Ensemble 2016.1.

The highlights of 2016.1 are

• Significant improvements in JSON support
• Continued advances in SQL performance
• Database scalability improvements
• New REST services for DeepSee

These and other new features are summarized in this video introduction to 2016.1

For complete technical details of what’s changed in 2016.1, review the Caché release notes and the Ensemble release notes.  

Straight-forward way to do it is well known and looks like this: 
------------------------------------------------------------ sample #1 --------

echo "Try to freeze Cache instance $instance"
rm -f $mydir/db_temp
csession $instance -U%SYS << EOF >/dev/null
zn "%SYS"
set rc=##Class(Backup.General).ExternalFreeze()
set fn="$mydir/db_temp"
o fn:("WNS"):1 if \$t u fn w rc c fn
h
EOF
read rc < db_temp
if [ "$rc" = "1" ]
then
 echo "...OK, system is frozen."
else
 echo "** Copy ABORTED: freeze rc = $rc"
 exit
fi

Introduction - Analyzing Textual Big Data

Big Data for Enriching Analytical Capabilities - Big data is revolutionizing the world of business intelligence and analytics. Gartner predicts that big data will drive $232 billion in spending through 2016, Wikibon claims that by 2017 big data revenue will have grown to $47.8 billion, and McKinsey Global Institute indicates that big data has the potential to increase the value of the US health care industry by $300 billion and to increase the industry value of Europe's public sector administration by Ä250 billion.

The big data breakthrough comes from

I have a %Net.Request object and I want to get a full URL of the request sent (preferably after all redirects, but even full initial one would be good). For example, I have the following method:

I want to determine what service (eg. %Service_Console) is used for current process.

I can probably use some workarounds, i.e.

• Is %request object present
• Does $Device  contain |TRM|
• etc

But is there any centralised way to get current service?

Here are a few tips that might be useful to people who are running applications in an environment that's configured to use InterSystems mirroring.

• If you configure an ECP connection to a Caché instance that is a mirror member databases then the ECP connection should also have mirroring enabled (tick the mirroring box when defining the connection). More details here. You may also need to increase the number of ECP connections each end accepts, to cater for the way both members of a mirror pair get involved in ECP negotiation.

• If your app server needs to update an unmirrored database on the

Hello everyone,

Is there a required bandwith between client and server for using Studio on a normal basis ?

Thanks

Hi,

posted some weeks ago in the "old" ZEN Google Group, maybe someone here can help to understand how to properly setting up a csp applications and contributing from the build-in caché security mechanism.

I´ve created a webapplication and wan´t to add further security to it using the smp. But... first things first.

I have two Databases let´s say DB1-LOGIN and DB2-Application. Each of this DBs has a resource assigned. DB1-LOGIN has a resource %DB1-LOGIN which has a public permission of 'read'. DB2 has a resource as well %DB2-Application with no public access.

I have defined two roles webapp-admin

Among the outputs of our Yuzinji tool are two code metrics that it can be interesting to track over time as a development project proceeds. These are Size and XS. The first is fairly straightforward. As you write more code the size of your codebase increases. The XS metric (pronounced "excess") aims to quantify excessive structural complexity. XS is explained in some detail in this 2006 whitepaper from Headway Software, whose Structure101 toolset Yuzinji leverages.

By analyzing a codebase using Yuzinji at key milestones we can investigate how these metrics change.

>/tmp/compilew.log &>/tmp/compilew.log ; tail /tmp/compilew.log

Hi,

i want the JAVA-Projections and wrappers to compile after Caché created the files. The creation of the files works 100%.

If I have defined a class query in one of my classes and I want to use that query from a method of another class, what are the pros and cons of using the %SQL.Statement interface versus the %Library.ResultSet interface?

I believe %SQL.Statement is the newer interface.

So if the old way is:

USER>s rs=##class(%Library.ResultSet).%New("%Library.File:FileSet")
 
USER>s sc=rs.Execute("c:\s\","*.txt")
 
USER>w sc
1
USER>while rs.%Next() {w !,rs.Data("Name")}

...

then the new way is:

USER>s oStmt=##class(%SQL.Statement).%New()
 
USER>s sc=oStmt.%PrepareClassQuery("%Library.File","FileSet")

Hello! 

I'm trying to run a simple SQL query in atelier but it complains about the manager.  I'm not sure if this is the best way to do it but here is what I got so far:

	ZNSPACE "User"
	
	SET domId = 1
	SET flister=##class(%iKnow.Source.SQL.Lister).%New(domId)
	SET myloader=##class(%iKnow.Source.Loader).%New(domId)
 
 
	SET myquery="select top(10) EntityValue, CorpusFrequencyAsRelation, CorpusSpreadAsRelation from %iKnow_Objects.EntityUnique  WHERE DomainId = 1 ORDER BY  CorpusFrequencyAsRelation desc"
	SET idfld="EntityValue"
	SET grpfld="CorpusSpreadAsRelation"
	SET

In the documenations at this location http://docs.intersystems.com/enscomm20152/csp/documatic/%25CSP.Documati…, the normalize method applies normalizaion for text using the defined manguage and dictionary.

I want to normalize my iFind queries. How can I use the normalize method ? any code sample ? 

I want also to delete properly the iFind index. Deleting all the rows in the table is sufficient ? 

When quering iFind is it possible to get also TFIDF scores ? any code sample for this ?

Thank you for the help.

I have a tablepane in my Zen page that is tied to a class query.  When the page first loads, the table is empty.  A button onclick event causes the tablepane query to execute and load query results into the table.  I want an onchange event from a datalistbox to clear the tablepane so that it looks empty as it was when the page first loaded.  I have had no luck fiddling with javascript in the datalistbox's onchange.

A simple and rather automated search portal leveraging iFind capabilities for rich text search in 2016.1. It has simple faceting, result ranking, highlighting of search results etc and just works off any table you point it to that has an iFind index by appending ?t=MyPackage.TableName to the URL.

I need to perform additional checks before Cache user logins (let's say in a terminal for simplicity) and allow access only to those, who passed them. How do I do it?

After reading about delegated authentication in docs I created this ZAUTHENTICATE routine:

ZAUTHENTICATE(ServiceName,Namespace,Username,Password,Credentials,Properties) PUBLIC { #include %occErrors #include %occStatus quit $$$ERROR($$$GeneralError,"No access") }

and set Password and Delegated as Allowed Authentication Methods   in %Service_Console (it's a windows install)

Expected result: no one can login via the terminal

I would like to know how to get the key value from a dropdownmenuitem placed on a navbar.

I have tried to get from onselect and onchange events of the template class, but it didn´t  work.

According to the snapshot attached I am trying to retrieve the values from 'action-1' and 'action-2'. 

I have attached a ZIP file with a snapshot which value I am trying to retrieve and example classes.

Hi,

Can a Cache Mirror be  used in the cloud ? (ie stand up a Primary and Backup member instances in a High Availability Cache Mirroring configuration) 

I'm investigating the validity of this configuration, because I was of the understanding that this may not possible due to these cloud servers not (typically) having fixed ip addresses, which interferes with the Virtual IP settings for the mirror set.

Is this correct, and if there are workarounds (like Load Balancing ?) can I have details on how this should be configured ?

I'm assuming other options like traditional Windows Clustering, or a
