Caché

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?  I can only see a full clear() in the documentation, but nothing which can remove individual elements

 

Thanks

Chris

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

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"))

:FILE:c:\file1.txt
sim(1)=$lb(1,":FILE:c:\file2.txt", 0.4239, 0.8615, 184, 78, 563, 0.4239)
sim(2)=$lb(2,":FILE:c:\file3.txt", 0.3967, 0.7704, 184, 73, 318, 0.3967)
...
sim(49)=$lb(49,":FILE:c:\file49.txt", 0.3967, 0.7704, 184, 73, 318, 0.3967)

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

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.

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 only?

I thought I understood Web Server Side and Client Server Side until I started looking into them, both in InterSystems documentation and outside documents

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?

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

-----------------------------------------------------------------------------------

Documentation states that the same can be written in much more short and readable style (and it really works):

------------------------------------------------------------ sample #2 -------

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?

Hello everyone,

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

Thanks

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. Here's a screenshot from a public repository we created from the classes in the SAMPLES namespace starting with Caché 2010.2 and reaching to recent 2016.1 and 2016.2 Field Test versions

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

In the documenations at this location http://docs.intersystems.com/enscomm20152/csp/documatic/%25CSP.Documatic..., 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.

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.
