Hello to all,

I'm trying to post some form data from a form I made in React to the backend of cache fetching a REST-service.
Receiving and processing a JSON-object is no problem but how can I handle Form Data?

The frontend is sending the form as form data and also includes one or more files.

What is the easiest way to process this data in my REST.Broker- class?

Best regards,

 We are using Native .NET API from IRISProviderCore21 package, inside .NET Core app, and having issue when trying to call function that takes instance of the class as parameter. The server is IRIS 2020.

 In a nutshell, the code looks like this:

            // Create instance of the parameter class, proxy object

            var paramObject = iris.ClassMethodObject("MyParameterClass", "%New") as IRISObject;

           paramObject.Set("property", "value");

We have a custom FTP Service , and custom FTP adapter . Customization is just to find a duplicate file and for giving specific dynamic file spec pattern.
While running and polling for files, we are getting this error. Could you please help ? What's the issue and how to resolve it ?

ERROR <Ens>ErrFTPListFailed: FTP: Failed List for <FileName> (msg='Cache error in 'readResponse': <READ>zreadResponse+4^%Net.FtpSession.1',code=426)

I searched to see if there was a previous question on this, but I didn't quite find anything.  Please link if you think this has been answered before (I have a feeling it has): what are the barriers to source control using Cache 2018 and Studio?

Hi All,

In earlier cache version, I can see full data values in SQL management portal.

But IRIS restricted the view only to 100 chars.

"If the data in a field is longer than 100 characters, the first 100 characters of the data are displayed followed by an ellipsis (...) indicating additional data." - From Documentation.

Is there a way to change this behavior ? I would like to see all the values in the particular SQL field.


Thanks in advance,

Archunan K

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

I am trying to use %ZEN.proxyObject to send out in JSON format so I do:

    set tProxyRequest = ##class(%ZEN.proxyObject).%New()
    set tProxyRequest.notanumber = "28001"
    set tProxyRequest.aboolean = "true"
    set tBody = ##class(%GlobalCharacterStream).%New()
    do ##class(Ens.Util.JSON).ObjectToJSONStream(tProxyRequest,.tBody,"aelotwu")
    w tBody.Read()

and I get:

We are working with a vendor who only accepts JSON as payload. We are currently still on Cache/HealthShare, not IRIS. Since we have to send Continuity of Care Documents, this raises issues with Long Strings (some CCDs can be quite large and in addition to that, they have to be b64-encoded which increases their size even more).

My question is: if we were to go on IRIS and use %JSON.Adapter, storing the encoded Stream in an object's Stream property, would calling %JSONExport() on this object produce the desired JSON? Or would we have to call %JSONExportToStream()?

Anyone know if it's possible using cache objectscript (or something else maybe) to reference an object property using a variable? For example:

s obj={}

s obj.prop1="hello"

s var="prop1"

w obj.var    <== which would result in a reference to obj.prop1 and write out "hello"

When using Studio, ODBC or a terminal connection to Caché or Ensemble, you may have wondered how to secure the connection. One option is to add TLS (aka SSL) to your connection. The Caché client applications - TELNET, ODBC and Studio - all understand how to add TLS to the connection. They just need to be configured to do it.

Configuring these clients is easier in 2015.1 and later. I'm going to be discussing this new method. If you're already using the old, legacy method, it will continue to work, but I would recommend you consider switching to the new one.

A permanent job opportunity has arisen for a Caché/Ensemble /Iris developer with at least 3 years experience. My client is a specialist resource provisioner of developers for high profile clients in the finance,  healthcare, retail, distribution and credit business that are mainly based in central London. My client is looking for a highly-motivated individual who thrives in an environment where problems are open-ended.

Code migration using VSCode

I am fairly new to using VSCode. I have used VSCode to create some files on our Test Server, now I need to move them to Production.

Looking through the VSCode extension documentation, maybe I missed it but how to I migrate code from one workspace to another. In Studio I was use to exporting the code into an XML and just being able to import it on the Production server version of Studio.

I am trying to connect to an external SFTP. They have our public key and I have the private key which is password protected. I have the credentials set to the sftp username and the password to the private key.

If I set the private key only, I get a username/password error connecting. If I set both the public and private key files, I get the error below:

ERROR #7510: SSH Error '-19': SSH Error [80101013]: Callback returned error [80101013] at Session.cpp:418,0

Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?


This is giving error.

I like to be able to call an "autohotkey" executable message box from within a running Cache routine executing as a jobbed routine. The autohotkey executable displays a small pop-up window with a message and an "OK" button .. and will time out in 10 seconds if the user does not press the OK button.

Although $ZF(-1,cmd) executes (where "cmd" contains a simple batch command e.g. @c:\autohotkey\warning.exe), no interactive window appears and, once the autohotkey routine times out, the calling cache routine simply continues.

SQL Query returns x00

Hey Intersystems Community-Member,

Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.

What is the best option to disable that? I need here  a empty String and not /x00.

Any ideas?

Best regards,


Florian Hansmann

I need to create a util function that loops thru every character in the data, execute a $ASCII() against it. If it falls outside the realm of extended ASCII we toss it.

the function should receive a string, execute a for...loop across it's length and use $ASCII to evaluate the character. Also the function should return an output argument that indicates if the string is UTF8 valid or not.

could anyone help me with this?
