Hi.. I have an issue where we are using OAuth2.0 with the ZAUTHENTICATE routine. Once our token is validated we are using a users lan id (passed on the ID token) to find a software defined username in a Cache Global.

That is all working fine in ZAUTHENTICATE.. I am setting the software defined username in the Properties("Comment") array and wanting to reference it in the Rest Service Dispatch class.

Hi everyone

I see that a new Apache bug has been discovered, and since various InterSystems products use an Apache webserver, have Intersystems released any news or updates on this? I'm not seeing any updates, press releases from them. Anyone know anything?

How To Create "Write-Only" Code

One of the leading benefits of ObjectScript is the speed and efficiency it allows for an experienced developer. Let's look at an example of how you can benefit from ObjectScript today.

Suppose you have a class that stores the names of your users. We'll call the class Data.User, and give it a string property Name. Next, we will need a method to create a new user or update an existing one. A naive, simplistic approach might look like this example:

Hello,

One of our AP would like us to provide the file upload/download sample code by using ZEN Mojo.

I already provided them the attached "upload-sample".

I tried to create the "download-sample" in a similar way, but I couldn't do it yet.

Does anyone have a good idea/sample about this?

I'd like to download the server side file(e.g. c:\temp\nene.jpg) into client machine with a OpenFileDialog(image.png).

Thank you in advance.

The first installment of this article series discussed how to read a big chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. The second installment discussed how to send files and their names wrapped in a JSON format.

Now let’s look closer at the idea of sending large files in parts to the server. There are several approaches we can use to do this. This article discusses using the Transfer-Encoding header to indicate chunked transfer. The HTTP/1.1 specification introduced the Transfer-Encoding header, and the RFC 7230 section 4.1 described it, but it’s absent from the HTTP/2 specification.

Thanks for all replies in advance. In monitoring our audit log we are getting the error below. We have 4 different servers running CACHE 2014.1.1 and this is happening on all 4 of them. I have not been able to find what process is trying to logon but it is happening every 30 minutes. We have no user processes that are running so this has to be a CACHE process. Does anyone have an Ideal what could be running to cause this? What kind of trace can I run to determine what process is running it?

Hi Team,

A month ago, we purchased the cache license for a 10user limitation. We are a 6developers and using 3different development (internal)servers for this same license. All Developers aren't login at the same time. We have a limitation for login 2developers at a time in a server. But sometimes, we are facing a <LICENSE LIMIT EXCEEDED> issue. We don't know why we are facing this one. So anyone please guide me, why we are getting this type of issue. I have attached the errored screenshot.

10000 clients simultaneously

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

Hi community,

I need to write an SQL query to fetch a random record from a table, that table has millions of data.

In postgresql, for example, there is a RANDOM() function to do something like that:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Is it possible to do something like that in Caché?

Thanks in advance

Hi,

In an Ensemble message bus that has a Business Service which extends EnsLib.SOAP.Service, I have the option to support SOAP Sessions by setting the parameter SOAPSESSION=1.

The comments says this also effects license consumption.

In what way is license consumption effected ?

note this is version 2015.1, Ensemble Elite (without Web-AddOn).

thanks -

Steve

Hi folks!

I have an example where I want to write a string into a file.

I have a message with string and I want to write the string down into a file.

I took EnsLib.FilePathThrough.Operation which expects Ens.StreamContainer message.

So I perform a data transformation where I need to transfer string to a stream. Here is the DataTransformation:

There has been some confusion about how to edit Business Process Language (BPL) and Data Transformation Language (DTL) files in Atelier using the graphical editor. The following steps describe how to do this with Atelier version 1.0:

Copy the file you want to edit from the server to an Ensemble-enabled project in your Atelier workspace. To do this, find the file in the Server Explorer, right click and select Copy to project.

Open the file in the Atelier class editor just as you would any other class file.

BPL - Foreach IF statement

As part of a BPL I am building I need to foreach over a some repeating elements and look for a certain value, if said value is present I need to forward the message to another operation.

I can't seem to get the if statement inside the foreach loop to work and I think I am doing something wrong?

The error message I am getting:

ERROR <Ens>ErrException: <UNDEFINED>zS2+2^GWH.Messages.Eobs.AKISegmentCheck.Thread1.1 *k1 -- logged as '-' number - @' Set k1=request.GetNextIndex("PIDgrpgrp("_(1)_").ORCgrp()",k1,.tSCTrans)'

Can anyone explain that error to me?

I have a project where I will need to take an HL7 messages and transforms it into a multi-line flat file. I tried creating a complex record map but those require leading data to identify the record type I'm dealing with but based on the destination vendors spec they do not want any leading data prior to the actual data being sent. Also the lines in the output file require different pieces of data pull from different HL7 fields in the messages and in the third field in the flat file I need to generate a unique line number.

Any assistance would be greatly appreciated.

Hello,

I'm trying to set up an Apache server using CSP Gateway on Windows 10 (64-bit), but am getting the error "Cannot load c:/InterSystems/IRIS_2019/CSP/bin/CSPa24.dll into server: %1 is not a valid Win32 application" when attempting to start up httpd.exe after adding the CSP-specific section to httpd.conf.

The CSP gateway is 64-bit (CSPGateway-2018.1.1.643.0-win_x64) and so is the Apache install (httpd-2.4.38-o102q-x64-vc14).

The CSPa24.dll file does exist in the specified location.

Any suggestions appreciated.

Thank you,

Olga

You may experience errors executing Java programs that rely on the JAVA_HOME environment.

For example when Create PDF from this pivot in DeepSee or in this case, outputting a Zen Report as PDF.

You can verify the PDF generation configuration by clicking on the Verify Now button on the Management Portal System > Configuration > Zen Report Settings page:

When we are at the starting stage of BI project development, we must remember that it is crucial to select the right tool for its implementation. Today we want to show you how one of the principal functionality of dashboards is implemented in different BI systems. Let's talk about drill down from both points of view: the dashboard development, and the convenience and clarity for the end user. We will touch on the applications of this technology in IRIS BI, Power BI and Tableau.
