Earlier, I've written about command pipes.
This is the internal variant of a PIPE.

To make this more tangible and visible for you, I prepared a small example
  The scenario is to run a monitoring process that receives
input from an unknown number of sensors.  (Could be Lab equipment or similar.) 

The monitor should not poll its sensors nor run
in a hang loop to scan a common global and work independently of any disk access.   
To try it log into a terminal 
.    DO ##class(IJC.Demo).%Start()  
The Highlander principle applies for this example: There can only be one  

Next, open a new terminal and run
.

Question Sebastian Thiele · May 17, 2019

Hi everybody,

after importing an XML schema from xsd into Ensemble I´d like to add it to my Studio-Project but can´t find the imported schema in the namespace view. For example when working with custom hl7 schema, I could easyly add it to my project under namespace view schemaname.hl7. Is this also possible with xml schema? If so where can I find it on an component level?

kind regards,

sebastian

Question Nijeesh Balan · Apr 24, 2019

Hi,

I would like to use EnsLib.HL7.Operation.HTTPOperation for sending HL7 messages via HTTP. It sends the Content-Type as "text/html"

I would like to change it to something else, say "text/plain". I cannot see a way to do it.

I have now written a custom Operation (based on EnsLib.HTTP.OutboundAdapter) and modifying the Content-Type while POSTing using SendFormDataArray(). It's bit frustrating to parse the response etc.,

I would rather prefer to use HTTPOperation of HL7. Can somebody help?

Thanks.

Question Murillo Braga · May 31, 2019

Hi guys

I have always struggled with this, tended to use workarounds but now decided to hear from more experienced people if this is something I am misunderstanding.

I need to basically add a "send" within the ruleset number 2, but without a need to associate a "when" node to it. Is this possible? What I basically need is to forward messages with status 160 to "ManageEDM" and also regardless of the status, it should get sent to "ManageRIS"

So what I need is the "send" to be present where the green arrow points, not where the red arrow points.

Question Jimmy Christian · May 31, 2019

Hello all,

I have a Recordset object  which contains data from a table "XYZ". 

Currently i use this object to extract data using  %Get(COL1,COL2...) in a loop and than pass it to a function which inserts the data into another dynamically created  Table "ABC"  for each record. This takes a lot of time when 100's of records.

Is there a way i can directly copy a RecordSet to a dynamic table without looping through..?

Something like copy Recordset (COL1,COL2..)--> "ABC"

Thanks,

Jimmy

Greetings,

Is there any default exception handling feature available in Zen report? I am working on a report that comprises of several different composites report (%ZEN.Report.Display.composite). I am incorporating several composites into the main Zen report, If any composite fails or encounters an issue such as issue with the sql statement or class method which i am using to fetch the data, the report (pdf) fails and shows a Zen error. It is very hard to find an exact composite or code that causes the error as Zen report displaying a generic Zen Error without any details.

Hi All,

I have a REST dispatcher class in which I enabled the Parameter HandleCorsRequest = 1;

I can able to access the API using Postman, but not with my web application. It throws the below error.

Access to XMLHttpRequest at 'https://ec2-10-200-XXX-X.com/REST/MRM/get/Message?MessageCode=ERR0006&L…' from origin 'https://ec2-80-106-XX-XXX..com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is this something need to be modified in the apache config file ?

Running a Background Job using the JOB command is a well-known feature.
Using ECP to distribute databases to several servers is also well-known.
But using the combination of both to run a process on a different server
seems to be a rare case.

Sure there are enough other ways to start a remote job, but the special
combination with ECP where the application server starts a process on a
data server without additional networking is worth to be remembered.

The example starts a remote process and receives back a result.
The parameters sent and received are pure demo purposes and require
adaption to the

How do I send request on production start?

Here's what I got so far in my production class:

ClassMethod OnStart(pTimeStarted As %String) As %Status
{
    job ..InitialTraining()
    quit 1
}

lassMethod InitialTraining() As %Status
{
    hang 5
    set sc = ##class(EnsLib.Testing.Service).SendTestRequest(...)
    quit sc

Is there a better way without hang, etc?

Question Robert Foster · May 27, 2019

Hi all, 

I am trying to create multiple tasks all in a single task. 

For instance MyApp has three tasks.

One to send a email if a limit is exceeded = MyApp-check-credits

One to purge files = MyApp-purge

One to auto delete files = MyApp-Del 

I would love to get all tasks MyApp-check-credits, MyApp-purge, MyApp-Del into a single parent task called MyApp-AllTasks.

Is there anyone that could give me guidance of how to complete this it would be much appreciated.

We are currently trying to implement TortoiseGIT into Cache Studio as per the following Github project

https://github.com/intersystems-ru/cache-tort-git

Our architecture is as follows:

- A server with Ensemble installed on

- Team of several members connect to the server and perform their code build

TortoiseGIT was installed on the server, however, should the REPO location be:

- on the server itself (as a shared path)? 

- locally on every developer station? If yes, how would this be set up?

This example is extracted from a long-running installation.
The purpose is to have simple monitoring of several servers at a rather primitive level.
Just slightly more intelligent than a raw PING. But still easy to integrate.
It avoids the overkill of information you are often confronted with while you are just
interested in the number of active processes or similar basic figures.
The example shows a basic skeleton that might be easily filled by your real needs.

It consists of 3 sections:

  • the data section to hold server access data
  • the server section to run unattended at the server you want to

Hi Guys, 

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

http://ser-app-w/REST/CRM/Get?ReqID=123(GET): return a 404.

I am using Apache server in Linux box.

I am not sure what I am missing in the config.

httpd.conf file (pasted required part):
