Hello Community,

Thank you all for your continued feedback and support of our ad hoc reporting platform, VDM.  There's been some questions around setting up a non-ODBC connection for InterSystems platforms.  We published a new YouTube video showing the steps necessary to connect to InterSystems Caché and InterSystems IRIS with BridgeWorks VDM. 

Happy new year! I’m Raj Singh, InterSystems’ product manager for Developer Experience and  I’d love your feedback on how you use IDEs today and your thoughts for the future.

We understand you depend on a solid, intuitive and flexible IDE from InterSystems - whether you are an ObjectScript expert or new to it; whether ObjectScript is at the core of your applications, or you develop more in Java, Python, C# or Node.js.

Did some quick testing replacing Intersystems.Data.CacheClient.dll with Intersystems.Data.IRISClient.dll and ran against Cache 2018.1 and IRIS 2019.1. Seems to work in both cases. Is it a safe assumption that the IRIS dlls are backward compatible with Cache 2018.1?

Some readers of my previous article, Caché eXTreme for .NET - direct access to globals from C#, wondered if you could access information not just from the same instance in which you’re working, but also from another instance on the same computer, or from an instance located on another computer in the same local network. Some theorized, correctly, that this would be possible using the Enterprise Cache Protocol (ECP). In this article I’m going to show how it can be done.

BridgeWorks is pleased to announce a VDM, v9.1.0.1.  This release includes the following updates:

Updates

• Historical Linking is now based off connection profile name
• Saved Formatting is now based off connection profile name
• Tables and Fields column headers no longer hide based on connection type

Bug Fixes

• Cross tab would not load data correctly in Finished Reports Viewer if it was in a report footer
• Fixed an issue where refreshing logs would not work correctly after viewing a SQL statement
• Views were not visible for available schemas on the connection wizard

I have SQLCompute with SQLComputeCode on a couple of Properties in my class.

These work fin when I insert/update via ObjectScript or SQL from the ManagementPortal.

However, if I insert (create new record) via my C# app using the Caché ODBC DLL the SQLCompute is ignored, it does not run.

Is this expected InterSystems Caché behaviour? We are on latest IRIS platform.

When calling the below stored procedure using the management portal (Run Query) no data is being retrieve, but if it is directly executed management portal data will show.

"IN" does not work changing it to "=", "like" the stored procedure will work. Does any one know how to fix this ?

Pass values to code is  'AB','TS','SK','GM'

}

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")
---
That executes the method and returns the reference as a string to a %SQL.ClassQueryResultSet.
Obviously I would

In .NET Core you have an option to extend a session using a "sliding expiration". This means that if over half the time has passed and the user actively uses their session then the expiry timer gets reset and the user remains logged in. This can lead to the curious situation where you have an active authenticated user with an expired access token being used in data-access requests.

Hello Everyone,

I Have an executable on my server and want to open it locally by a Caché Command.

Ps. Caché database is also on the server side.

The .NET Core Identity model has an IPasswordHasher<> interface for  for 

• Hashing a password so that it can be stored in a database
• Verifying a provided plain-text password matches a previously stored hash. 

I am getting invalid password errors during the login process when the .NET Core Identity model computes a hash from a plain text input and compares it to a password hash value I've returned from Caché. The default hashing algorithm is PBKDF2 with HMAC-SHA256, 128-bit salt, 256-bit subkey, and 10,000 iterations (detailed article on .NET Core Identity PasswordHasher). The algorithm Caché uses is probably different which may be why I am getting errors.

Has anyone used Cache \ DeepSee for graphical curve fitting and data reduction using Cubic Spline and/or 5 PL for complex curve fitting

What would a sample DbContext look like and how would you register the DbContext in the Startup.cs  ConfigureServices method?

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:

ClassMethod ObjectFromObject(o As %RegisteredObject, class As %String = "", package As %String = "") As %DynamicObject
{
i class = "" s class = o.%ClassName()
i pack

Hi, 

what is reason of this error (Not all parameters bound/registered ). this is not happening consistently.

those are class method parameters

Query GetWorkItemsByEncounterID(encounterID As %Integer, userId As %Integer, IsSuperOrDev As %Integer = -1, facilityAccessListCSV As %String(MAXLEN=32000), locationAccessListCSV As %Library.String(MAXLEN=32000), skipReferralFilter = 0) As %SQLQuery [ SqlName = spGetWorkItemsByEncounterID, SqlProc ]
 

Hi, I have a CSV file with a list of 5000 records in the following format

Name, Acc, division

Eric, 1234, 567

John, 1235, 987

Peter, 3214, 879

I just want to copy the Acc, division to a global so eventually the global would be like the following:

^People("Customers", "Acc.division")

Can you advice on how I can perform this from the terminal? This is a one time task. I want to read all the values from the csv file and insert them into the global

Hi All,

I want to implement SAML in Cache without SOAP webservice  Please suggest any ideas?

Thanks,

Hi All,

Is it possible to call a Cache Routine using the .NET Cache Client instead of just SQL statements?

If so, can someone provide an example?
using InterSystems.Data.CacheClient;
using InterSystems.Data.CacheTypes;

Thanks,
-Matt

Does developing a RESTful API in Caché remove the requirement to use the InterSystems.Data.CacheClient.dll and generate proxy classes using the Caché Object Binding Wizard for .NET web development? If anyone has links to sample applications using .NET with Caché and REST Services, I would be grateful if you could share them.

We have an application made in asp.net and want to make a integration for our client who is using cache database. So can any one suggest how to communicate with the database as we are new to this system.

Has anyone managed to port ASP.NET Identity Caché Provider  to ASP.NET Core?

Edit: this one https://github.com/intersystems-ru/identity_cache I mean

WRF to below example my idea is to check whether red is present in the list mylist.  You can very well use LINQ on enumerable in C#

mylist.Where(x => (x.Property2 == "red")).ToList().Count;

set mylist=##class(%ListOfObjects).%New()For i=1:1:2 {S object = ##class(User.NewClass).%New()
  Sobject.Property1=iS object.Property2="red"do mylist.Insert(object)}

It can be done with iterating over mylist

for j=1:1:mylist.Count(){Set item = mylist.GetAt(j)
   If (item.Property1 = "red") { // get the count }
   //set exist = item.Find("viv",1)}

I am trying to achieve this in cache objects I am using  2014.1 here is the original code in C# and would like to convert this to cache

here is my code first c# and cache follows

        /// This function loads a XML document from the specified string.

I ran the below query in three different modes.  Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection). 

I don't know  why query 2 and query 3 outputs different from query 1.

Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)

'Hour ' returned are same for both the columns

Query 2. Ran in ODBC mode, DATEPART() took in memory stored timestamp

I have a main page in .NET where I call a Dashboard created in DeepSee like this:

<iframe src="../..zen?DASHBOARD=NameofDashboardKpi1.dashboard&EMBED=1&CacheUserName=&CachePassword=" 

to display the Dashboard in the .NEt page.

My problem is that connection to every Dashboard takes a while, so performance is low.

Any suggestion?

My scenario is:

I have a Cache method that

call a REST -> JSON -response  > INSERT/UPDATE the source table of a DeepSee Cube -> Update the Cube only for this change -

I want to view in .NET Application the changes. For that I want that this method should be executed at a defined interval.

Or maybe the solution is a Refresh button in .NET page. is there any way to access a Cache method from .NET?

Any idea how to do it?

We have some productions in Ensemble that uses DotNetGateway to use dll created with .Net. The DotNetGateway is configured with a port number, and then the operation uses that port.

But sometimes, suddenly Ensemble answers that the port is already in use, but it is only used by the DotNetGateway. And the only way to resolve this and make the port available again, is to restart the full server. We have tried to restart Ensemble, to kill the process that may be using the port and nothing. Is there any way to make a DotNetGateway port "stay connected" or 
something to search who is occupying the

More calls in parallel to a single .Net Gateway can yield better performance, but too many could cause problems. What is the "Right" number? What do you do/recommend?

Hello,

I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.

Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?

Any guidance in this area would be appreciated.
