Caché

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.

Best Regards.

We have a data transformation where source is object collection (populated from a json file)  and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to:

Hello,

lets have two  abstract %Persistent classes A,B with NoExtent keyword (storing data in separate globals for each subclass).

Class A Extends %Persistent [Abstract, NoExtent]

{

}

Class B Extends %Persistent [Abstract, NoExtent]

{

     Property Aref As A;

}

Let B class reference the A class. Since the A class has no extent the reference wont work in subclasses. It wont be even usable in SQL.  Is it possible to solve this problem? Whats the recommended way to deal with references/relationships using NoExtent?

Hello,

I had an issue when using the method Exists, I noticed that if you provide a directory for this method it returns 1.
This is really misleading, because sometimes the input could be a directory and the only way to predict this is to also test if the file is a directory.

I didn't tested using the Attributes method, but I supposed that this means could also be a solution for that issue.
But still, I expected the Exists method to return 1 for files and 0 for directories, since there's also method called DirectoryExists already.

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.

My database service is on the cloud server, and I access it on the company intranet. When I user the %request.CgiEnvs  to get "REMOTE_ADDR", but what I have been getting is the company's external address. I can't get my IP address in the LAN. 
For example, my computer IP address is 192.168.11.11, and my company's external public network address is 214.17.17. I can only get 214.17.17 by using %request.CgiEnvs("REMOTE_ADDR"), but not 192.168.11.11.   

I only want to get 192.168.11.11.

Dear Colleagues and Friends,

is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.

I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:

Our lab system is now sending DSC segments in large Pathology results in the ORU message that is followed by a partial continuation message with only MSH and OBX segments.  the  pointer is in the MSH;14 in the subsequent message.  I believe the goal is to concatenate the first and second message but imagine this will require some custom functions which I have not done much of.  Anyone already tackled this by chance? 

Initial message:

Edit:

May have found the issue but not the solution.

"SELECT * FROM wmhISTORYdETAIL" runs as a passthrough without asking for the DNS.

but

'SELECT Count([wmhISTORYdETAIL].[HistHMNumber] AS CountOfHistHMNumber FROM [wmhISTORYdETAIL] WHERE ((([wmhISTORYdETAIL].[HistMovType])='Receipt') AND (([wmhISTORYdETAIL].[HistMovDate])>=Date()-1) AND (([wmhISTORYdETAIL].[HistMovDate])<Date()));'

asks for the DNS but both are linked to a table that has the password saved.

Any Ideas please?

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hello all,

I have an XSL question and I wanted to see if someone within a community can help me out.  

To Summarize: I am working with XSL documents, single and multi-pages.  
Inside my style sheet XML document, which is supporting my pages, everything on the page, including a headers, footers and the items are calculated 
based on the portrait measurements. 
Pages come up on the screen as portrait, but sometimes, depending on dynamic data are wide, they do not print properly in portrait.
