Hi,

I have a large XML zen report file that I want to convert to a CSV, what is the most efficient way to do it.

XML file:

<Details>
<Col1> aa1 </Col1>
<Col2> bb1</Col2>
<Col3> cc1 </Col3>
</Details>
<Details>
<Col1> aa2 </Col1>
<Col2> bb2</Col2>
<Col3> cc3 </Col3>
</Details>

Expected Output:

Col1,Col2,col3
aa1,bb1,bb1
aa2,bb2,bb2

Thank you.

Hi all,

Over the next few months I'm going to be setting up continuous integration via Jenkins for some Angular UI's.  The goal is to, on each build:

1. build the code

2. run the unit tests and get a report

3. get a code coverage report

Just wanted to poll the community in case someone else has already worked with any of this before.  All ideas are appreciated.

Cheers,

Johnny

Hello, everyone,

I'm trying to find solutions to a problem that's becoming quite boring.
On only one namespace, the sudio is very slow.
The studio freezes completely for 5-10 seconds when I save or compile a class. Sometimes it also freezes for no apparent reason at a random time...
It stops when I change namespace...

Do you have any idea what that could be?

Thank you in advance

Hello friends,

I am trying to create REST API in Cache. I am getting a response from postman but when I tried to launch the same URL on the browser, I am getting service unavailable error.

This is my URL

Any help is greatly appreciated.

Thanks and Regards,

Hi All,

I have a class method, this can be any cache expression to execute (usually a class / method and args) and and args stored in a variable, for example;

set aa = "##Class(Utils.Test).Run(1,2,3)"

do aa

I tried using $classmethod(class,method,args..), by extracting the values but sometimes there can be no arguments, or arguments such as ;

("2019-01-01","1,2,3,4")

which causes issues while running the $classmethod, (i am using $P to extract the Class, Method and args).

 

Is there any simpler way of doing this?

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.

I am having trouble sending URL encoded payload to eFax in FormData. Does anyone have experience working with the eFax? Their support is not the greatest.

This is what I am trying to send

s rObj.ContentType="application/x-www-form-urlencoded"

d rObj.InsertFormData("id", "123456789")

Hello, I created a Zen Report and I want to export to Excel. I read I can use $MODE=xlsx but my output in Excel is not correct. All 3 elements are condensed into one cell. Class AETMON.Report Extends %ZEN.Report.reportPage { /// Class name of application this report belongs to. Parameter APPLICATION; /// Specifies the default display mode used for this report if /// the URL parameter, $MODE, is not present.

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.

Currently one of our applications, coded in Cache, performs web service API calls out to one of our vendors.   We now need to be able to send a Client ID in the portion of the Soap envelope.  

I  think I have a clue of what I need to do but not 100% sure.  We were thinking we could use the method %SOAP.WebClient.SetHttpHeader(field name, value) but when I have tired using this method and looked at the Soap log to see what is sent, the field is never showing.  I realized I could be setting the wrong object using the method.

We often have troubles with performance when joining  tables  with about 10 million rows together.

Sometimes we can't say what the cache engine is doing, it's just sucks and never finishes.

Then we have to rebuild the query and loop first on Orders and then on OrderPositions.

this is what we want:

EDITED: the join was only forgotten

ENSTEMP was addressed already some time ago; 
Article: Preventing Globals From Getting Journaled (Continued from How do I Minimize My Journals)

and is also in public documentation
Where InterSystems IRIS Stores Temporary Production Data

Though I'd like to understand if this is just naming a non-journaled DB
or are there also typical features of CACHETEMP / IRISTEMP related to it:

  • automatic clean-up at system startup 
  • keeping Global Buffers in memory as long as possible
  • late writing to the storage file 

In other words is it a 2nd, 3rd, .. fully feature blown IRISTEMP  ?

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

Now, in where condition I want to do like search in DisplayName column but it not working.

I have tried both fn CONCAT and  || in like query but both are not working for me.

IRIS offers Durable %SYS Directory as a highly useful feature for working with containers.

Before inventing the wheel once more I'd like to know if a similar feature also exists for Caché / Ensemble.
Official documentation is quite silent about.
Though I have some names in mind that might know more about   ( @Luca Ravazzolo @Dmitriy Maslennikov  ?     @Eduard Lebedyuk ?  )
