In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions. The majority of solutions I see today are deployed on Linux on VMware so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

During migration from Caché to IRIS I can preview a situation where some instance
have migrated to IRIS while others are still on Caché.
For various reasons this may be in place for some weeks or even months as the big bang isn't feasable.

So far I found a lot of statements related to mixed endinans,
but nothing related to cross operation beween IRIS and Caché.

?? any hints ??
?? any experience ??

Behind the scenes at docs.intersystems.com, there is plenty of challenging, interesting, and (did I mention) challenging technical work to get our content published and to continue to modernize our tool set and improve our customer experience. We are looking to hire someone to help.

The job includes digging into and expanding our automation tools, identifying & setting up useful testing, and lots of creative thinking. Most of the automation tools are written in ObjectScript, and knowledge of SQL would be helpful as well.

For IRIS 2019.1 and later, the documentation has a new look and feel. Check it out:

https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls
 

The underlying changes include a new style sheet and a complete rewrite of the code we use to generate HTML.  (There is now an underlying API for retrieving content as JSON, as well as a large set of unit tests -- for those of you who like that kind of thing!)

We have in DB two books, first is loaned because it has the Friend ID, and the other is in the shelf.

        FROM Library.Book
        WHERE Friend IS NOT NULL
    }
 

Which I have tested throught the portal:

I  am reading the following code in ObjectScript:

GitHub repository
 

And there is a sentence which I am facing difficulties to understand:

    kill ^OPNLib.Game.CWLF(..World)

I know that kill removes variables, OPNLib.Game are the package and subpackage, and ..World is a property. However what does CWLF mean?

You could think that it is the class' name, but it is:

I am trying to work through our upgrading steps from 2015.2.2 to Health Connect 2019.1. Is there a place online I can access previous versions of Health Connect documentation? I am specifically looking for Health Connect 2018.1.2 documentation so I can understand the upgrade process on AIX.

 

Thanks

Good Afternoon,

I'm working on a API documentation that wil be interactive, it's based on a BS class on Ensemble.

The objective on making the documentation is simplify the undestanding of the operation for those who are not acquainted with the Ensemble environment.

My problem is, when using Postman to test a operation the indentation appears as such:

Hello,

as you can see in title my problem is with file ccontrol. I want to install whole Ensemble with Manifest if on machine wouldn't be any, or if I somehow find out instance of Ensemble I want to only use settings from included Manifest. I read that I can use file ccontrol to solve this task.

So can someone said me, how to work with ccontrol, is there some variable or function which returns me somethig? I have read some parts of documentation about ccontrol, but nothing help me so much, so you can give me link to part in documentation, where is this desribed.

The problem is that I want to set some variables here in .cmd file and use them in Installation Manifest for installation Ensemble. It is about variable with path to some packages which should be imported during instalation.

If you know the path of a file that exists in the instance's install directory, how can that file be opened and edited in Studio? This file is not saved under the visible directories in Studio ex csp or mgr. For example if you have no access to the server operating system command line, how would you be able to modify a file using Studio?

PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.

Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:

Hi,
I am facing issue during LDAP lookup like whenever I used product group parameter in AD explorer to search data from application I am getting empty result. If I set product group parameter as null then based on distinguished name result is generated in application. So if anyone knows about how LDAP works and how parameters are set in AD explorer then please let me know.

Thanks in advance.

I use Documatic a lot to generate class documentation from comments embedded in the code. Is there a good way to create documentation for SQL views as well? Ideally I want to document each column in the view with HTML markup similar to how I document each method of a class with Documatic.

The InterSystems DBMS has a built-in technology for working with non-structured data called iKnow and a full-text search technology called iFind. We decided to take a dive into both and make something useful. As the result, we have DocSearch — a web application for searching in InterSystems documentation using iKnow and iFind.
