1.  Use $$DIR^TRACE(dir)  you haven't set a suitable directory
2.  Use $$ON^TRACE(5352)  ; the job you want to trace ==> open file
3:  USE $$OFF ^TRACE(5352) to stop trace ==> close file
4.Now ^TRACE should show the file

I traced my own studio session:

START:1810291850,0,%SYS.BINDSRV,2,1

Not sure for Caché 2017 
BUT
Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2018.1.5 (Build 659U) Mon Mar 22 2021 07:12:43 EDT
Has ^TRACE in %SYS
with enough $v(..) and $ZU(..) to look promising 

 W $ZU(5)
%SYS
%SYS>D ^TRACE
 
TRACE utility for Cache. You can signal a process to write a record of all
procedure, function, or subroutine calls to a file. Then use this utility to 
interpret and display the trace. The trace file is named: CacheTrace_'pid'.txt 

Use $$DIR^TRACE(dir) to set the directory where the file(s) should be written
(process must have create/write access to the directory). $$DIR^TRACE() returns
the current directory for trace files. 

Use $$ON^TRACE(pid) to start the trace and $$OFF^TRACE(pid) to end the 
recording. Then just run ^TRACE to see the results. 

Process ID for trace file:

So  %SYS>d ^TRACE might be a useful start

This utility traces the execution of a process.  Traced processes write events
to a trace file with details about the routine line where the event occurred
and, if applicable, the global reference.  The events available for tracing
correspond to the metrics availabe in performance monitoring tools (PERFMON,
%SYS.MONLBL etc).  Raw data is written to iristrace_<pid>.txt in the
configured directory, and is then parsed and displayed by this utility.
 
 
Trace file directory:   not set
Trace file size limit: unlimited
Trace events selected:  RtnLoad, GloRef, BlockWait, NCacheMiss, DirBlkRd
   UpntBlkRd, BpntBlkRd, DataBlkRd, BdataBlkRd, MapBlkRd, OthBlkRd
 
1) Configure Trace
2) Trace Process (Foreground)
3) Start Background Trace
4) Stop Background Trace
5) Display Trace Files
6) Delete All Trace Files
 
Option?

If I understand it right, you do not just expect a tracking down to some point, 
but also a history of all up and down you did from a certain starting point.
Similar to a TCP traceroute

AH,  That was meant by feedback
Which is easy now, as it wasn't a bug but an explicit feature

like this:
Calls a function (label^routine), passing zero or more arguments and returning the function's return value. Trailing arguments may be omitted, causing default values to be used for those arguments.

This method throws an exception when an error condition is encountered.

routineName

input

The name of the routine that implements the function to be called.

functionName

input

The name of the function to be invoked.

args

input...

The arguments to be passed to the method.
 

return

The value returned by the functionName function.


  • Such a misleading documentation roughly 1.5 years behind reality is not so impressive
  • It took days to find this out.  😖

quite an interesting hidden feature.

Though testing with _SYSTEM/SYS and %All, this had no visible impact
It is exactly 1 method that breaks in all 4 Nativ packages 
And with %All the rest is available anyhow and working fine.
 

BUT eventually %All is not All enough

Robert Cemper · Aug 1, 2025 go to post

Thanks for the input.
A good idea to put the demo in a separate repo
It is just not directly obvious from OEX
works fine, and module.xml looks good. Review placed

>> Naming in ObjectScript has a historic background 
In the beginning, the grand-grandfather of IRIS was a full-stack operating system
And it was running on machines with only 64 KBytes of memory
So saving space in memory was the highest virtue of a developer then.
Consequently, all names were as short as short could be.
Typically using single-character named variables.
And A was different from a to widen the available scope
Over the years, this was kept for backward compatibility and to decrease the fear of upgrades
And I have seen customers running 40+ year old code also in IRIS without any bit changed.

In your screenshot, I see 

$('<div>') simpledialog2(

But W3Schools says:
https://www.w3schools.com/Jquery/jquery_syntax.asp

Basic syntax is: $(selector).action()
  • A $ sign to define/access jQuery
  • A (selector) to "query (or find)" HTML elements
  • A jQuery action() to be performed on the element(s)

I didn't write JavaScript for decades, and I'm not an expert.
BUT: I fail to detect the point after the closing bracket
It was just my Studio that marked it as an error.

I wonder how you expect to know that your input is complete without any terminator.
And according to your example, you also don't have a fixed length:
Withoit an clear signal timeout seems to be the only way to know you are complete.
You may read input character by character without guarantee  
how do decide for 1 or 10 or 100 or 1000  ?
Some ending character (eg. not numeric) or a fixed length is required

Confirmed. I just checked:

The correct syntax is &html <   your  content  >

I didn't detect the closing > in your screenshot

It generates:
Write "  your content  "
in the resulting .int code
Just the same as it did in Caché or Ensemble

My personal preference would be

  • verify Websockets with a js client (even in CSP)
  • then move it to IRIS with all hidden and default features if required at all.

You may check all the old WS examples in OEX

Hi 

your code
Set WebSoc=##class(%Net.WebSocket.Client).%New(WebSocURL,cre,evl)   
Just uses the Default %Net.HTTPrequest that contains url port, ....
But %New offers more
• Methode %OnNew(pURL As %String, pCredentials As %Net.WebSocket.ICredentials = $$$NULLOREF, pEventListener As %Net.WebSocket.IEventListener = $$$NULLOREF, pAcceptedProtocols As %String = "", pRequest As %Net.HttpRequest = $$$NULLOREF) als %Status
and in %Net.HTTPrequest you have a property port
https://docs.intersystems.com/iris20251/csp/documatic/%25CSP.Documatic.cls?LIBRARY=%25SYS&PRIVATE=1&CLASSNAME=%25Net.HttpRequest
I never needed it as protocol ws and wss was sufficient.
But there is no other place for a port to be assigned
 

Robert Cemper · Jul 16, 2025 go to post

You mentioned:

WebSockets are enabled on ports 80 & 443, but the code fails

Websockets work bi-directional
SO: Did you assign / map  those ports also in your docker-compose ?

Possible workaround:

Your source seems to contain the <br/>
Try a different separator e.g. @ to verfiy it.
If it is in and you can see it, HTML tags < > might be escaped for some reason and not be
