Hi -

I've been trying to create a "sub packaged class" (i.e. TopPackage.SubPackage.Classname) but the current version of the "New Class Wizard" doesn't seem to allow me to do this.

If I try to specify a \project\subdirectory in the "Project" or I try to specify a Package.Subpackage form in the "Package", or I try to specify "Subpackage.

Good day, Cache developers and users!

At first, sorry for my bad English -)  I have a little question.

As I know, we can add database to mirror only on Primary Failover Node, using SMP or ^MIRROR. And the usual procedure after that is to copy mirrored database to Backup Failover Node and restore it there (by Backup restore or by Activate-Synchronize procedure). This all works fine. But what if I first have copied the database from Primary to Backup and only than added the database to mirror on Primary Failover Node? (human forgetfulness).

I'm trying to figure out what is the best (or at least pros & cons) on how to manage login accounts in a multi-tenant SaaS web based application context.

Assume that a company is designing a collections of web based applications that they will be selling as "services" to their clients, and that these clients will each have their own "users" and "customers" that will be logging into these services.

In setting up these login accounts for the "users/customers" of the "clients" of the "company", does setting up a unique domain/user-pool context for each "client" make the most sense?

I installed Atelier on Windows in order to take a look at how the BPL and DTL graphical editors accessible via the "Open diagram editor" action work. The diagram editor is opened but I get the following error:

Message from webpage
---------------------------
Unable to load SVG diagram. Please ensure your browser is supported for portal access.
It looks like Atelier uses IE in order to display the editor even though my Windows default browser is Chrome.

I tried to change the General -> Web Browser setting to "Use external web browser" and choosing Firefox or Default system web browser.

Often when debugging COS code you get an error message such as '<UNDEFINED>test^routine *test' so the first thing you want to do is to take a look at this code and see what it is doing. From the command line you can:

ZLOAD routine ZPRINT test

Which means splitting the $zerror information into the routine name and the line and adding the zload/zprint commands. Also you often want to view the lines above the one where the error happened as this gives you some context of how you got to this line, using ZPRINT you could 'ZPRINT +1:test' but that may display hundreds of lines.

Since 2013.

I have some logging code that outputs task status information to a log file. I would like to make the log available for reading while it is open for writing. The file is opened using the "L" option (Lock):

Open tLogFile:"WASL" Set tLogOpen=1

My intent was to prevent multiple processes from accidentally writing to the file and having messy output. Unfortunately, if the process is taking longer than expected, one can not simply open the log file to figure out what is going on because the "L" lock prevents the file from being opened for reading as well as writing.

I'm using Atelier 1.0.145 on Windows (x64). When I open the Help menu from the menubar the final entry (About Atelier) has a huge version of the Atelier icon alongside it. This distorts the menu. I can't post a screenshot here because my simplistic screen capture tool causes the faulty menu to close. But the large icon I see is also (correctly) displayed on the About box itself:

This isn't a new problem in build 145. I also had it in earlier ones and had been holding off from reporting it, assuming that it had already been noticed by someone at ISC.

Hi -

I would like to change the initial text that is generated by the New Class wizard in Atelier, but I'm not sure if I can or where to go to make the modification. I have a specific format for initial classes, and the wizard generated code isn't cutting it for me. I know it's trivial to take the generated text and just modify it, but if I could only have to do that in the wizard, that would be better.

The more generalized question is, which wizard output can be safely changed without fear of losing the change on upgrade, and where are these?

Thanks

Configuration

Cache 2016.2 running on fully patched minimal CentOS 7 install. No Firewall.

Atelier running on Centos 7 Desktop. No Firewall.

I was able to build and compile classes from Atelier.

When I try to run a routine or some class code from Atelier I get an error.  It tells me to look at the Network Activities view.

When I do that I see the following:

 Time:1462820585806 Server: debugger WEBSOCKET:csp/sys/atelier/%2525Atelier.v1.XDebugAgent.cls Message:null
 Time:1462820585944 Server:  WEBSOCKET:debugger.

This question came on the Ensemble in Healthcare email list. It's a great question. I'm working on an answer, but am posting it here to get any other input. I'll also address the option of using %CSP.REST.

Hello everyone,

Using Intersystems Healthshare/Ensemble, I am trying to make a RESTful Interface between Android/iOS app and Cache database. I have some queries and I am unable to find where exactly I can get any resources on them.

1. By extending the EnsLib.REST.

Greetings! This article describes yet another simple way of creating installers for the solutions based on InterSystems Caché. The topic covers applications, which can be installed or completely removed from Caché with one action only. If you are still documenting installation instructions that have more than one step to do to install your application — it’s high time you automated this process. 

I am trying to execute a system query. - %SYS.Journal.File_Search()

The Query is looking for a Journal File Name and a String.

However, the Query line accepts no parameters. - Query Search() As %Query(ROWSPEC = "Offset:%Integer")

But in the SearchExecute method if checks for File and String.

ClassMethod SearchExecute(ByRef qHandle As %Binary, String As %String, FileName As %String . . .

Our company is looking for someone with expert object script skills and experience developing with REST using Caché. We have an existing application that currently supports a mobile application and a web application. The API is up and running but we need another developer to add new features and keep up with demand.

Experience with Amazon AWS is highly desired as the api is running on Windows in EC2. Familiarity with GitHub is also required.

Pay can be negotiated on a per hour basis after you provide an estimate for the time required to complete a given feature.

I was writing a routine that called some class methods and when I typed in ##class( and the package, there was a drop down list of all the classes that match that package but when I selected one of the dropdown entries it added the package name again.

For example if I enter ##class(dim.

I am presented with a list of classes in the dim package but when I selected one of them,(dim.OccupationList), what ended up in the editor was

##class(dim.dim.OccupationList

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 

{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

In case of sc contains error execution will be routed to try catch block. You can wrap any Status methods calls in your code if you need to catch the errors coming from them.

I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.

I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.

How can I load a dll at run time using COS?

I have a class which, in the previous instance, was able to extract metadata field names and data from a text file, and load this information into a domain. I am trying to run this in the field test instance, but it is not loading the metadata - only the field names. I am not getting an error, but the data is not loaded.

The few changes I made to the original class:

Previously, this class also ran iTables. I commented all that code out.

To create the domain, I replaced the line:

  set tSC = ##class(HSTA.DomainExpert.utils.DomainUtils).%CreateDomain(dname,.

I have a scenario where I am calling a business operation which populates  and returns an EnsLib.SQL.Snapshot via dynamic SQL to a Business Process. I then want to iterate over this snapshot and call a RecordMap Operation to write those records to a delimited file.

Is this the correct way to do something like this? If so, does anyone have a sample which illustrates its correct usage?

When the snapshot is returned I save it into a context variable with:

set context.Snapshot=callresponse where the pOutput variable of the operation is set to EnsLib.SQL.Snapshot.

We are in the process of putting a new UI on the existing product documentation, including a mobile-optimized view. We also plan on releasing additional "solution based" documentation that is targeted at common usage scenarios or important configuration tasks.

We are interested in your feedback on our current product documentation - what you like and dislike and especially what changes you would expect to see to make it as useful as possible.

You may experience errors executing Java programs that rely on the JAVA_HOME environment.

For example when Create PDF from this pivot in DeepSee or in this case, outputting a Zen Report as PDF.

You can verify the PDF generation configuration by clicking on the Verify Now button on the Management Portal System > Configuration > Zen Report Settings page:

Outputting a Zen Report as PDF causes an error, for example ZENApp.MyReport.

2015.2.3 Maintenance Release

Zen Mojo 1.1.

I'm used to using Class/Refactor/Override in Studio to override methods, properties, xData blocks, etc regularly.

I can't see how to replicate that in Atelier at the m moment. Is this possible ? 

During the Unconfernce and Sessions during the Global Summit several folks had questions and wanted to see how Ohio State setup our Managed Alerts.  Attached is an export I did along with Documentation I had given to our group here at OSU for Managed Alerts.

Good afternoon, I have working prototypes of each of these approaches. I do not have an expansive cache background.

I have a couple of projects where I am ingesting files from disk.

The name of the file contains a lot of the information I will need to reference the file in the future.

What are the advantages and dis-advantages of these two approaches:

Store the whole filename and use SqlComputeCode to populate properties in a class?

Parse the data out of the filename on ingestion into properties in a class?

For each approach what are the implications to indexing?

Thank you.

Hi,

I sometimes get asked if Weblink will still be available (as a downloadable ad-on these days) for some versions to come. 

I realize that this is old technology now, and that there are better and faster ways to do the same things today.

Thanks

On the class reference %Library.GlobalCharacterStream is marked as deprecated in favor of  %Stream.GlobalCharacter.

How I can migrate the data from class properties defined as %Library.GlobalCharacterStream to the new one %Stream.GlobalCharacter? 

Does the %Stream.GlobalCharacter have the same SQL support from %Library.GlobalCharacterStream?

Thanks.

Hi all,

Do you have a sample to set EnsLib.Workflow.TaskRequest.%FormTemplate point to a Zen page?

I got "ERROR creating application object" when doing so. A simple sample would be appreciated.

Hello,

I am trying to router a custom message using the content of one of its property, but this property is a List. ¿How I can do it?

The rule could be something like this

<rule name="">
  <constraint name="msgClass" value="Test.TestMessage"></constraint>
    <when condition="Document.myList.GetAt(1).property1=&quot;AA&quot;">
      <send transform="" target="DummyOperation"></send>
      <return></return>
    </when>
</rule>

But this rule doesn't compile.

TestClass is a simple Request Class like this:

Class Test.TestMessage Extends Ens.

I have a need to query and retrieve DICOM images using the 'pull' method of C-FIND and C-GET.  I have seen examples in Ensdemo where Ensemble is a target of pushed messages.  Has anyone used Ensemble this way?  If so,  can you share and example?
