Internal Structure of Caché Database Blocks, Part 1  407

Caché and Ensemble 2016.2.

I am looking for samples for integrating Ensemble and RabbitMQ. Any pointers appreciated.

What will it take before Cache begins to appear on (or at the very least be considered for) such lists?

hi,

1. Created a class(test) and added a classmethod(checkdata).

2. Assigned a object with xml.

3. Created a new class for response and initialized in classmethod(checkdata). 

4. Created a new class for request parsing with list of object parameter.

5. While parsing xml in request for list of object,  the  result count is "0". But the xml has value for "2" object list.

6. XML has follow:

<Request>
    <party>
        <to name=""mohan"" address1=""India""  />
        <to  name=""sujay"" address1=""USA"  />
    </party>
</Request>

Hi, Community!

We deployed the new update on DC and it brings:

• The new post subscriptions/favorites model
• Some menu changes
• Bug fixes.

The new post subscriptions/favorites model:

with every post you now see the star in the left bottom corner of the widget in the feed or of the post.

Click on it and it turns to yellow which means that you store it in your "Favorites" tab which you can find later in your member's page like it is shown in my one.

Also, that means you automatically subscribed to email notifications on all the changes in this post.

Click it again to unfavorite/unsubscribe the article.

Is there any method or routine available to export and import the user roles and the sql table and sql procedures associated with each role?

NewBie's Corner Session 22 Parameters Part III

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

In Sessions’ 20 and 21 on Parameters we saw how to call one routine from another with parameters as well as calling one Label from another with parameters. In these examples, the data was passed through the parameters from the calling routine or label to the called routine or label.

Now suppose you wanted the called routine or label to pass data back?

There are two ways** of doing this.

We are finally planning to migrate some ancient Caché applications that are run on Caché 5.0.21 to a new server with Caché 2016.2.0 or so.

I wonder if we could use Shadowing between those to keep the data on the new server up to date?

We would copy the Caché backup from the old environment to the new and do a RESTORE there and then start shadowing.

I know than 5.0.21 is no more officially supported by ISC.

Hi,

We have created a dll with .Net that generates a MS Word document with a template. The .Net method works, we have tested it with Visual Studio and it generates the document.

But once we have created the dll and embebed it in Ensemble through the Wizard, when we try to execute the method that generates the document, it doesn't work. It doesn't throw us an error, it simply doesn't open the template.

We have seen that MS Word program is opened, but that's all.

We are using Microsoft.Office.Interop to generate the Word document. It must be Word 97 version document.

What are we missing?

After reading Stephen Wilson's article "Windows 7 performs shutdown too fast for Cache to close and so it gets forced down" I've recalled another solution that was based on Local Group Policy, which allows to control extra actions that should occur on computer startup or shutdown. How to add a computer shutdown script is well documented in MS Technet article. In short:

• being logged on as a domain admin, run Local Group Policy Editor (gpedit.

I'm working with a custom code in Studio and I'd like to know where a Class is being used.

The standard ctrl+f  search only in current file.

Hi-

I was wondering whether or not the Ensemble Event Log was accessible using SQL?  If so, what schema and table would that be contained in?

Thanks

Hi-

I was wondering if there was a DeepSee overview document available for a non-technical user.  Something short and concise describing what DeepSee is and its key features.

I've looked at the documentation and although there are parts of what I am looking for there it is much too technical for my needs.

Thanks

Hi - If you want to embed Ensemble's Workflow Inbox, (that offers workflow task items to workflow users) inside of your application - you can access the URL directly without necessarily giving users access to the Management Portal - but more importantly, you can strip away the Titlebar, Worklists and Borders that make up the page by default.

You do this by using the same URL parameters you would use, if embedding a regular DeepSee dashboard into your application.

For example, adding &EMBED=1 at the end of the URL as depicted below:

Hi,

I have an Ensemble DTL which is suppose to translate the inbound XML document to an outbound XML document.

I need to test if a particular XML element exists, to perform some translation.

In the DTL I have the following,

<if condition='source.{element1.element2.element3}'>

<true>

    // do something

</true>

</if>

How do you use if statement to test the source XML document to see if a particular element exists in the source doucment.

Thanks,

This article explains how Atelier helps you to improve software development productivity. One of the Ensemble features is the VDoc infrastructure. When someone develops HL7 v2.* production, She/ He is in a luxurious situation because Ensemble comes with a HL7 Schema editor. On the other hand this is not the case with XML VDocs. But with some effort you can turn Atelier to a handy XSD editor and close the gap.

Please follow the step-by-step guide to complete the job.

Explain Class(set) Operators and the `(Grave) Operator in Normal and Pattern Expressions? With Example.

It has been noticed that some customers running JAVA programs (for example, FOP) on AIX would see the server eventually running low then out of memory. Customer would notice the system pages heavily and user experience becomes bad. And the server would crash when out of memory.

When the problem happens, we can see in ipcs a lot of shared memory segment marked for deletion (Capital D at the beginning of MODE section). This means they will not disappear until the last process attached to the segment detaches it.

Hi All,

            I have a general query in regards to developers experience on extracting data from cache databases and the most efficient way to do so. I work with a number of clients who have applications with cache databases and require the data off the host system and onto data warehouse platforms for research and analysis. Often they require the data in source state which means the extracts are often simply a table scan of the entire database table without any aggregation or manipulation.

Hi All

When using a select :

  {type:'$input',id:'Table-Alert-Alert', key:'Table-Alert-Alert', inputType:'select', children: [
              { type: '$loop', value: '=[AlertTList]',children: [
              {type:'$option', value:'=[id]', selected: '=[selected]', $content: '=[AlertText]'}
              ]}
         ]},
I can get only value & text of the selected object :

      $("#Table-Alert-ID").val($("#Table-Alert-Alert option:selected").val())
      $("#Table-Alert-Text").val($("#Table-Alert-Alert option:selected").

We at George James Software recently released a new version of Deltanji, the native source code management tool for Caché, Ensemble and HealthShare.

Version 6.1 includes several enhancements, including easy creation of labels. Bulk transfer of large codesets is also now available from the browser UI.

A perpetually free "install and go" Solo Edition of Deltanji is available. Licenses can be purchased for other editions that provide more advanced code management and deployment features.

Deltanji is compatible with Atelier. It can also manage external files.

Please visit http://georgejames.

Hello,

I'm a beginner in HealthShare, and I start to develop with caché some dataflow.

Some of my business process exist in java code.

Is-it possible to call these packages from caché classes ?

If it is, how can I do it in Caché classe ?

Thanx

I had default csp application: /csp/<namespace>  for a namespace.

Later I created another application: /csp2/<namespace>  and  made it default.

Yet all namespace-specific (Ensemble, DeepSee, SQL, etc.) links in management portal still point to/csp/<namespace>.

Is there any way to make the links in management portal point to /csp2/<namespace>?

NewBie's Corner Session 21 Parameters  Part II

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

In the previous session we saw how to call RtnB from RtnA with Parameters.

We also defined Parameters as another name for Variables when used in passing data from one Routine to another, or, from one Label to another.

Calling a routine from a Label, or to a Label, from within a routine is very similar to calling a routine itself.

Hi All,

We are Upgrading the Application from Ensemble 2009 to 2016.1. We have imported the user, Roles and Resources. But the Sql Tables and Sql Procedures are not being visible in Management portal -> Security Management -> User. Please give me a solution or basics steps for importing those.

Thanks, Manoj J

A beginner’s guide to position Ensemble in regards to MicroServices Architecture (MSA). MSA is getting more visibility in the Enterprise Java world therefore it is vital to understand what is behind the buzz. I make a (humble) attempt to write my view and share with you.

Background

First of all I must confess. Early this summer our Czech colleague Daniel Kutac was asking me to collect some information about a health care product developed in Hungary. When I got the feedback from the related company, it turned out, that the product is a modular system, based on MicroServices Architecture (MSA).

I am happy to share the news that Zen Mojo 1.1.2 has been released. This release includes a critical fix for Firefox that we had to get out as fast as possible. No other changes are included to allow easy upgrades. We recommend upgrading to this release if you are running on Zen Mojo 1.1.1.

All upcoming Caché and Ensemble releases will ship with Zen Mojo 1.1.2.

You can download Zen Mojo kits from the WRC distribution page: https://wrc.intersystems.com/wrc/Distribution.csp

Any fix or enhancement that was previously planned for Zen Mojo 1.1.2 will be included in the next upcoming release 1.1.3.

Hello,

does anybody know how to differentiate ZSOAP failures when using %SOAP.WebClient? I would need to know what error condition occurred, e.g. authorization failed, endpoint timeout etc.

All I get on failure is an ZSOAP exception which does not seem to explain anything specific.

Thanks

Jiri

Context: 

mirrored configuration with one primary member and one async member (without failover/backup member)

Purpose:

replace the CACHE.DAT of a mirrored database on the primary member.
