Question

I am configuring IIS to work with the CSP Gateway but I'm running into this error:

"The Module DLL 'C:\Inetpub\CSPGateway\CSPms.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture."

Hi all,

I was wondering, what is your favourite public cloud provider?

What is your level of engagement with the cloud provider? Are you testing their infrastructure? In which case I'd expect you being progressing a parallel test with at least a second provider ;-) Or, are you already running a production environment?

OK, so, let me be the first one to share my experience with one specific cloud provider.

Hi-

I'm curious to know what InterSystems clients are using for csp based web development methodology.

Are you doing tag based development, or class based development?

If you are using tag based development, what tools are you using to create the look and feel of your web pages?  Are you using tools like Adobe Dreamweaver, or do your developers sit down and code HTML using plain editors like Notepad and Notepad++

Are you doing prototyping of web pages and then adding CSP tags, or are you just developing the finished csp page with no prototype?

Thanks
Ken

In MSSQL I think you can do something like this:

select *
from HS_IHE_ATNA_Repository.COLUMNS
where TABLE_NAME='Aggregation'

How can I do this in Cache SQL?

[%msg: < Table 'HS_IHE_ATNA_REPOSITORY.COLUMNS' not found>]

I'm planning to have a web-based management and deployment interface.  For now I have started writing some .mac scripts.  Will I be able to call these from a web page?  Or do I just need to start with Zen?

C:\data\backup.bat :

C:\InterSystems\Ensemble\bin\cache -s"C:\InterSystems\Ensemble\Mgr" -U%%SYS ##Class(Backup.General).ExternalFreeze() <C:\data\login.scr 

echo %ERRORLEVEL%

rem note that we need to check errorlevel from highest to lowest here....

if errorlevel 5 goto OK

if errorlevel 3 goto FAIL

echo errorlevel returned wrong value

goto END

:OK

echo SYSTEM IS FROZEN

xcopy c:\InterSystems\Ensemble\mgr\ z:\backup\Ensemble /s /e /y /i

echo %ERRORLEVEL%

goto END

:FAIL

echo SYSTEM FREEZE FAILED

:END

rem Now unfreeze the system

Developing an idea with RuleEngine in XData, we could even refuse from editing full class and edit only valuable xml. Sometime ago I have already written an article(in russian) about such possibility, even more, in that article I wrote about compilable JavaScript to Caché. 

Opening File

This possible with %Studio.AbstractDocument. While extending this class, developer should add a Projection.

Some days ago Alberto has written a very interesting article about the usefulness of ObjectGenerators available in Caché.

In this article, Alberto shows an example RuleEngine based on XData, and how it is possible to improve the process of filling such rules. Caché Studio has a Studio Asist for XData; you may have already seen examples of it if you use ZEN or %Installer.Manifest.

Let's say the user need to execute some heavy code (build a report, or extensive calculations etc.). So, of course it needs to be asynchronous, and we possibly need to store some data about execution status. How?

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.595.0.

It may look like a slow week, with less than fifty changes having been checked in, but this kit includes the following fixes to problems found by you, the ones running the kits in the field:

• ALE2845, which fixes the cachejdbc.jar version
• JN1637, which fixes an issue that blocked debugging Atelier when used in conjunction with Kerberos
• DLP3508, which fixes a JSON issue with $compose()

The rest of the fixes have been spread among different areas of the product, chief among them DOCUMENT Data Model, SQL and Atelier.

Does Caché support a relationship property ordered according to a specifc value? 

What shoud be the best approach? 

The attached file contains an example of code generation using ObjectGenerators which builds a very simple homemade RuleEngine. 

Code generation is an excellent way of increasing performance moving run-time calculations to compile-time.

We could generate code creating routines or implemeting methods using ObjectGenerators. In this example we are using ObjectGenerators.

Update: Rule Engine is now on GitHub https://github.com/intersystems-ib/cache-iat-ruleengine

A very simple code generated method

For starters, let's begin with a very basic code generated method:

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

The cache has error messages default, for example , " -139 SQLCODE : Competition impairment on the update: row versions are not the same. "

How i can exchange it for a more friendly to the user's message? I use the CSP.Page and form_save ( ).

What is best practice for this situation?

Caché Monitor is a database\sql tool primarily for InterSystems Caché but can also connect to MS SQL Server, MS Access and more databases. Within Caché Monitors Server Navigator you see all available Namespaces on your Caché Servers. No need to know the name of the Namespace, no need to configure many many JDBC Connections by hand. Just click on the namespace and see all objects like tables, views, classes and more...

In preparation for a presentation I need a  real-world LDAP schema that has been customized a bit beyond the basics.   Perferably this would be based on an OpenLDAP system which would make it easier to merge into this presentation. 

If you have such a schema you would be willing to share please respond or contact my directly at Rich.Taylor@InterSystems.com

Thanks in advance.

Here is my original query:

SELECT EventType, InitiatedAt, COUNT(*) as cnt
FROM HS_IHE_ATNA_Repository.Aggregation
WHERE EventType = 'LOGIN'
AND LocalDateTime > '2016-02-16 11:00:00'
GROUP BY EventType, InitiatedAt

This gives me data like this:

However, I need to get the data back as two columns with all but the last concatenated and delimited, more like this:

I tried this:

I'm interested in different approaches on how to store user data in Caché. I'm assuming that application uses Caché security/Caché users and not a self-made authentication system.

Several approaches, I'm familiar with:

Looking at a property defined as follows:

Property SystemTime As %Library.TimeStamp [ SqlComputeCode = {Set {*}=$ZDATETIME($NOW(),3,1,0)}, SqlComputed ];

The documentation talks about using SqlComputed and SqlComputeCode with SqlComputeOnChange (specifying which events will trigger computation), and about using them with the Calculated keyword (so it's always computed). I don't see any specific explanation of the case above, though, when neither SqlComputeOnChange nor Calculated is specified.

From a bit of testing, it seems that the behavior is:

Given the following code:

I get <UNDEFINED>start+4^DeploymentTool *tstVar
 

I also tried setting the variable outside the start method but that doesn't work either.  I realize I could pass tstVar to the TestIt() routine but I'm trying to create a couple variables that will be reused repeatedly so that doesn't really work.

Hello,

I am trying to log the output of csession in Linux. I try this command:

csession cache | tee myoutput.log

Although it works each new lines at screen output doesn't appear at row 1...

Any tip?

I am pleased to announce the third 2016.2 field test kit, 2016.2.0.590.0.

In the week since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.  Unlike the previous field test kit, though, in which the changes were distributed evenly over multiple areas and products, in this kit over half of the changes are associated just with Atelier.

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.

I've searched the ObjectScript reference for any instances of Upper, Lower or Case and the only thing is a case/switch statement.  In all the documentation I can only find SQL and Cache Basic references for things like UCASE.

So how do I do this in ObjectScript?

For instance, if (ucase(dtype)="G") { }

Has anyone come up with a way to create a separate thread of processing that can achieve shared access to a set of objects created from the initials process?  The situation is this.  There is a large complex set of objects representing a business process.  Some of these objects are in-memory only.  The desire is to spin off a separate thread that could do some ancillary processing on this data set without slowing down the main process.   Any thoughts?

Hi!

Are there any plans to support Kerberos authentication in Atelier to Caché connection?

Thank you.

Do to unforseen circumstances the Atelier build that was distributed with the Cache 2016.2 field test had certain incompatibilites which prevented it's effective use with the server that it was bundled with.

We are working on remediating this regretable situation and will provide a compatible Atelier in the 2016.2 field test refresh which is scheduled for today Monday, 1st of Februrary.

We sincerely apologize for any inconvenience so caused.

Hi,

Do you know how to export SQL errors to a text file from a terminal session in Caché?

Thanks

I am pleased to announce the next in the series of 2016.2 field test kits, 2016.2.0.585.0.

In the two weeks since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.

In Atelier alone there were over a dozen changes including a fix for the incompatibility issue that Jamie Newton described in his posting of February 1.

In Caché major areas of focus include:

• SQL (ten changes),
• ECP and mirroring (11 changes),
• Objects and JSON (13 changes),
• DeepSee (nine changes), and
• Documentation (23 changes)
