We are currently implementing the Data Innovations Instrument Manager product. In setting up our backup process we are wanting to use Veam snapshots. The application runs in a Caché 2016.1/Windows Server 2016 instance. We are running an HA primary/secondary/arbiter config. The statement below is from DI. I am curious to see what others that have implemented the DI Instrument Manager in the same or similar config have in place for backup.

"DI recommends is recommending that we not perform snapshots, but if you do choose to do so, here is some important information to consider.

I have a custom written date, setup as myDate in my application, which always behaved fine for years, and now it's acting a little weird.

When I run SQL in Display mode the date shows as 1/10/1841 for some but not ALL rows.

When I run the same exact query in logical Mode the date shows normal format, in my case, for example 10/1/2019. When the application is running is shows the incorrect date. When I run the terminal session and open a ref point and ask to write a date is shows 10/1/2019, but I am expecting internal format here - 65287.

Compaction of Large globals

I would like to Compact globals in a database to free up space.

I would begin the process on Saturday morning, but am concerned, due to the size, that it would not complete by Sunday evening. I understand that the process is setup so that it can run with users on the system, however, as the advice indicates, this would not be ideal.

Can the process be stopped if it does not complete by the time you want/need it to?

Do you know how to guestimate how long the process would take?

Greetings community. I would like to know how to migrate a BD in production to a local environment. When I have a system in production (BD Sql Server) what we do is mount a local copy to do the analysis with the data and not occupy resources of the system in production. My question is: How do you do it with Intersystems technology?

Hi All,

We have a licensed version of Ensemble but for now, we use only the DB capabilities of Cache. As we create a custom Namespace, for e.g "Test", a new Ensemble Namespace is automically created by the system --"TestENS".

Is there any way where we can identify the system created ENS namespaces ?

Hello!
There is a class query “MemberStatusList” in the SYS.Mirror class that I would like to call from a .NET client application.
I know that means that there is also a generated class method called MemberStatusListFunc.
What is the best way if any exist to call them from a .NET application?
Just see if anything responded I tried using something like

IRIS iris = IRIS.CreateIRIS(conn);
var returnValue = iris.ClassMethodString("%SYSTEM.Mirror", "MemberStatusList", "NAMEOFTHEMIRROR")

Common Testing Frameworks.

Hi,

I'm after feedback and comments on the sort of tools and approaches the wider InterSystems community uses for QA Testing applications written in Cache/Ensemble or IRIS. I am aware of the %UnitTest package, and understand how that works... but:

- Do you use an alternative or framework built around this native Unit Testing tool ?

- What is your experience with %UnitTest if you use it ?

- Is there a tool you would recommend for your UI (I know this is not specifically an InterSystems' related question)

I was hoping for some input on the best way to deploy code to site with the following criteria:

- No source code, only compiled code to be deployed.
- Classes and Routines are part of the application.
- Data and code reside in the same database.
- Deployments might be partial updates (i.e. cannot just send a complete CACHE.DAT).

At present the idea is just to export the .obj, any suggestions?

I am integrating with Front End using ODBC to the Caché tables.

I have a property of type %Library.Time in one of the Caché classes FrontEnd which is in C#, it is not possible in C# to represent only a Time type, it always has a date as well (DateTime type, no Time only in C#), but that is fine, should not be a problem, so for Time the date simply defaults to 1900/01/01.

Now when this is sent to Caché it does not like it and I would like to understand why because this is causing us not to be able to use a Caché property of type TIME ever.

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:
