InterSystems Caché is a multi-model DBMS and application server. See more details here.

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.

Code metrics over time

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.

[SOLVED]

added

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

to redirect the output to the stdout. Somehow the javac has wierd behavior with the output on errors and verbose information.

Hi,

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

My addition to createProjection in our Projectionclass is following:

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 ?

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.

iFind Search Portal

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.

See also https://github.com/bdeboe/isc-iknow-ifindportal for more details and the latest version.

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.

Thanks.

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 ?

2016.2 Field Test Kit 2016.2.0.609.0

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.609.0.

This is a relatively light update with only a few dozen changes from the previous field test, spread out across all areas of the product. Also, in a break from the recent past, this update doesn’t contain any new fixes to problems found in the field.

Please download the kit and give it a try; the latest field test of 2016.2 is available HERE. And, as always, we welcome your feedback.

There have been a few use cases recently within InterSystems where we've needed to connect to Caché-based web services from PHP. The first of these was actually the Developer Community itself, which uses web services as part of Single Sign-On with other InterSystems sites/applications. The following example demonstrates how to connect to a Caché-based web service (particularly, the web service in the SAMPLES namespace) from PHP, using password authentication.

Alert: Incorrect SQL Results

February 25, 2016 – Alert: Incorrect SQL Results
InterSystems has corrected a defect that can cause incorrect results for certain SQL INSERT, UPDATE, and DELETE statements.

This defect is present only in Caché and Ensemble 2015.2 and HealthShare distributions based on them. The problem affects all platforms.

Incorrect results occur only when two or more of these statements are nested within each other.

The example below demonstrates one possible way for this problem to happen:

Who does Windows think I am?

When my COS code is executing in a Caché process it might want to interact with the host operating system. For the purpose of this post I'm focusing on a Windows host, but much of it applies to other host OS platforms as well.

A common example of host OS interaction is when my process wants to read from or write to a file. What credentials will apply when Windows is checking whether or not to allow me access to the file?

To answer that we need to consider another question. How did our process start?

If you've got more than one developer on a project, do you each work in your own namespace? Or do you all use a common namespace?

Through my work at George James Software I have encountered many different Caché and Ensemble development setups. At risk of over-generalizing, the older and more established users of InterSystems technologies seem more likely to have all their developers working in a common namespace, whereas the newer 'converts' tend to favour giving each developer their own namespace.

Hello,

This package may be of interest...

Link: https://github.com/litesolutions/cachedb-import

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

The cdirectmgr utility will no longer be included with product distributions beginning with the Caché 2016.2 release . This was an older VB application (predating the Caché cube) which allowed users to define server connections for Visual M/Caché Direct applications. As VB 6 is no longer supported by Microsoft, we will no longer ship this component. The same functionality is already available from the cube utility.

It is also posted in Compatibility blog.
