Question Virat Sharma · Apr 29, 2024

Hi Everyone,

We are using SQL based KPI's to display reports in IRIS dashboards. We have applied the filter functionality in these SQL based KPI reports.

I need your help for below scenario.

Below is my full report. Filter is applied on Name and Subject Name in this report.

Now I have used filter on Name and selected values 'Virat' and 'Big Show'

2 entries were displayed from 5 records.

Now when I look in Subject Name Filter, it still display all the distinct values of Subject Name.

I want this to display only Chemistry and Social (as Name filter got applied).

Dear experts,

I'm using a test enviroment to test freeze & thaw scripts on windows. I executed command:

Hi,

Is there anyway available to get the current status of Write Daemon through code?

Generally, this information is present in Management Portal->System Operation->System Dashboard->System Usage->Write Daemon.

Thanks & Regards,

Question Michael Davidovich · Apr 24, 2024

Hello, I'm curious to see how other people deal with this: we have a text file that was created on someone's Windows machine and it was copied and pasted into a text file on someone's Mac machine.  After some examination we realized that the line feeds were originally CRLF (for Windows) and when copied and pasted they were changed to LF (Mac).  The diff program we used didn't pick up on this and the program we wrote to read the file was getting each line of the CRLF file and treating the whole file as one line for the LF file.

Question omer · Apr 11, 2024

So as asked, I am not talking about KILL - KILL as stated in the docs:


This command removes the variable. If there are no further references to the object, this command also removes the object from memory,

 I want to remove the object from memory even if it is still referenced in memory - I understand that cache is not a low-level programming language, But i was hoping there is a way. 
Notice that have a RegisteredObject and it is a single reference, It is different than the UnSwizzles suggested in other posts.

Question David Marinkovic · Apr 23, 2024

Hello everyone,

I have an issue related to Visual Studio Code and its InterSystems extension when exporting routines from the database to the file system.

The code entered via the terminal editor is encoded in DOS code page 437, but when I export it to my file system, even if I set the file opening to DOS CP 437, the accented characters which are two bytes long cause problems.

Regardless of the test settings I've tried, the only one that retains meaning is CP 437, but I get an unnecessary character preceding my accented characters.

Hello everyone, I need some help. 

I have to send some events for a government WebService that I already imported the WSDL and XSD's and It worked fine and I'm able to build the message and connect into the service, but It has been rejected with the message that the XML is wrong and the only diference between the Caché SOAP message to all the examples that the government gave us is the header:
   

This is how the Government is expecting the message:

Question Maarten Van den Vreken · Apr 17, 2024

Hi all,

I was wondering if there is a way to modify the results you get in the code assist in Visual Studio Code. Ideally even per class or package.

For example: the code below is for a custom component of a framework. From all the options listed I'm only interested in my own property "Title" and I don't want to see any %-methods or auto-generated methods like "TitleSet" and "TitleGet".

I have been looking at the %Api.Atelier classes, but it seems that it's only calling a list of deprecated methods when opening this list.

Hi! I am planning to move my Arbiter from a Unix server to a container(again on linux). To do this, I need the ISCAgent tar.gz file to configure Arbiter for our mirrored servers. I have tried searching for it on the Intersystems help forums but couldn't find it. Is it possible for someone to redirect me to the correct website to download it?

Thank you in advance!!

InterSystems FAQ rubric

When you run a routine in the terminal and an error occurs in the program, if you have not set the error trap properly, the program will enter debug mode as shown below.

USER>do^error1
 write A
^
a+2^error1 *A
USER 2d0>

From this state, enter the Quit command to return to the state before the routine was started.

USER 2d0>Quit

If a transaction is being processed within the routine where the error occurred, a prompt similar to the one below will appear.

Question Paul Coviello · Mar 14, 2024

we are looking at replacing our VMS system with Linux :-( yes a sad day!

now the question has become should we go with Intel or AMD.  personally I think Intel is the way to go for several reasons.

has anyone seen or heard of an AMD being slower or there is a definite performance of one over the other.

thanks for your feedback.

Paul

 first our current environment which will be copied over to the new platform

Cache 2015.2 yes we are stuck here due to Vendor and no further support. with the upgrade we will be updating to a newer version of Cache and eventually IRIS when the vendor has certified it.

Question Julian Matthews · Apr 18, 2024

Hi everyone.

I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.

To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.

Are table hints supported with embedded sql?

I have an odd binary result exporting a specific routine via Studio, Export. Below is the beginning. The seemingly same routine in a different directory is exported fine, regular human readable code. Inspecting ^ROUTINE and ^rIndex did not give me any clues. Any insights?

Discussion ALEX VY. · Apr 13, 2024

Dear All ,  As per the title, 

I was tasked to upgrade an old legacy system to run on Windows 11. 

I am having a problem with Cache mostly.

I have the version: VERSION 5.0.14 , BUILD 5702 , OBJECTS 5.0.5702.0 I would like to know if there is a way to run it on windows 11 somehow.

I know I am asking for a LOT.  Unfortunately, the provider of the suit is long gone, and I can't keep it on windows XP.  Let me know if there is an alternative way to get it up to date even with the lowest / more recent version. 
Thank you in advance for your time.

[Background]

InterSystems IRIS family has a nice utility ^SystemPerformance (as known as ^pButtons in Caché and Ensemble) which outputs the database performance information into a readable HTML file. When you run ^SystemPerformance on IRIS for Windows, a HTML file is created where both our own performance log mgstat and Windows performance log are included.

If the journal file is too large to be searched or filtered using the Management Portal, you can refer to it using the following two methods.

① How to use the ^JRNDUMP utility
② How to reference it in a program

================================================== ========== 

① Using the ^JRNDUMP utility. For example, if you want to select all records in the journal file that include the global reference ^ABC, do the following:

*Please execute all commands below in the %SYS namespace.

DO SELECT^JRNDUMP("C:\MyCache\mgr\journal\YYYYMMDD.

If you have system tables implementing the "VERSIONPROPERTY" functionality, you may encounter error 5800. This article explains how this error occurs and provides solutions to resolve the issue.

When version checking is implemented, the property specified by VERSIONPROPERTY is automatically incremented each time an instance of the class is updated (either by objects or SQL).

For example:

ClassMethod RunVersionChange() As %Status
{
    Set sample = ##class(dado.TblSample).%OpenId("42")
    Write !,"VERSIONPROPERTY value: "_ sample.VersionCheck
    
    Do sample.

Question Colin Brough · Apr 8, 2024

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

  • The Operation uses class TNHS.SOAPclassExtra
  • TNHS.SOAPclassExtra  Extends TNHS.SOAPclass
  • TNHS.SOAPclass  Extends Ens.BusinessOperation
  • Ens.

Question Julian Matthews · Apr 8, 2024

Hi everyone.

Is there a sensible approach to having a lookup table in Namespace A, and then accessing this from Namespaces B, C, D (etc)?

I'm trying to avoid creating a Global mapping of the lookup table global (^Ens.LookupTable) as I fear that it would then link all other lookups in that global and lead to some unexpected behaviour, but would be open to trying something in this realm if it's the best option.

Another approach I have considered is creating a custom lookup function that is run from the secondary namespaces that does some namespace hopping, but it feels messy.

Question Stefan Cronje · Apr 5, 2024

Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.

Question Amiram Kasos · Feb 8, 2024

Hi,

I am trying to connect to another server using  %Net.HttpRequest.

I keep getting this error  : SSL23_GET_SERVER_HELLO:unsupported protocol.

My guess is that the site I am reaching for uses TLS1.3 which is not supported in 2016, But I cant right now ask my client to upgrade.

Is it possible to override this ? install some kind of a patch or a more recent version of openssl on the server ?

Thanks

Amiram
