Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In this third part of this article series I will show how to link our React app to our three back-ends we created in part 2.
I have an http adapter that calls out to a web service and is looking for a "Completed" response. I want the adapter to wait a certain number of seconds before calling out again to get a response. I have tried setting the retry interval on the business operation but that does not do it. See my code below.
While pResponse.StringValue = "Processing" {
set tSC=..Adapter.PostURL(tURL,.tHTTPResponse,,tId)
do tHTTPResponse.Data.Rewind()
set pResponse.StringValue = tHTTPResponse.Data.Read(3000000,.tSC)
$$$TRACE("Second Response: "_pResponse.StringValue)
}
Hi Community!
I'm pleased to announce that we've just launched the new product in the family of InterSystems Data Platforms:
IRIS for Health — is the world’s first and only data platform engineered specifically for healthcare. It empowers you to rapidly create and scale the industry’s next breakthrough applications.
I would like to know if it is possible to backup a database via shellscript in Linux?
Thanks.
There are some classes in our code base that contain Methods only (no properties). I told my colleagues that converting them into the ClassMethods should improve performance as it would eliminate unnecessary OREF support at run-time. Some of them replied that it would be microseconds, so what is the reason to bother.
Is it possible to estimate the impact of OREF support of method calls at run-time? E.g., as a % of all CPU load.
Hi Community!

Hi all.
As part of my dysfunctional journey with FHIR, I'm looking at using the SDA3 within Healthshare to then convert to the HSFHIR format.
This is working surprisingly well, except I'm falling over when it comes to repeating fields within the SDA3 when creating the HS.SDA3.Patient object manually from within Cache.
If I take the Patient ID as an example - within a DTL, I can quite easily take an MRN and add that to the target PatientNumbers.(1).Number and then add an NHS number to the target PatientNumbers.(2).Number.
InterSystems is pleased to announce that InterSystems Caché and Ensemble 2018 are now released!
New in these releases are features that improve security and operations, including:

· SSH enhancements
Has anyone successfully executed s (INTSFREEZE and INSTATHAW) scripts in atelier tool?
We are having issues with FREEZE script whereas Thaw works fine.
Would appreciate any inputs!
I created a Ens.Alert process and set my services Alert on Error as well an my message router. But I would also like to be alerted for warning types. Is there an setting to be alerted for this type?
Hi!
Did anyone try to serialize objects in Caché using Google Protocol Buffers? Your experience will be very helpful for me.
Thanks!
Hi all,
I want to export a production in one file, but it has some code in macros, include and class files. I'm exporting using portal (Classes / Select All / Export) but I need the same in macro's tab and copy the content in one file.
The following class method "test" contains code that can create a new class, create new properties for classes, or create new methods for classes. "test" runs all three of these processes once, and the code that performs each action is labelled by comments in the method:
ClassMethod test() As %Status
{
set sc = $$$OK
// Create a class
set class = ##class(%ClassDefinition).%New("MyClass")
set class.Description = "This is my test class"_$c(13,10)_"testing %ClassDefinition"
set class.Super = "%Persistent"
// Create a property and add it
set property = ##class(%PropertyDefinition).%New("MyClass.MyProperty")
set property.Type = "%String"
set property.Description="This is a property"
set sc1 = class.Properties.Insert(property)
do:$$$ISERR(sc1) $system.Status.DisplayError(sc1)
set sc = $$$ADDSC(sc, sc1)
// Create a method and add it
set method = ##class(%MethodDefinition).%New("MyClass.MyMethod")
set method.ReturnType = "%Integer"
set method.FormalSpec = "x:%Integer,y:%Integer=10"
set method.Description = "Return product of x and y"
set method.CodeMode = "code"
set method.Code = " new result"_$c(13,10)_" set result=x*y"_$c(13,10)_" quit result"
set sc2 = class.Methods.Insert(method)
do:$$$ISERR(sc2) $system.Status.DisplayError(sc2)
set sc = $$$ADDSC(sc, sc2)
// Save the class definition
set sc3 = class.%Save()
do:$$$ISERR(sc3) $system.Status.DisplayError(sc3)
set sc = $$$ADDSC(sc, sc3)
return sc
}
Here's a link to the code on GitHub
Let's say I have something like this:
Query ClientList(BusinessType As %String) As %SQLQuery (CONTAINID = 1, ROWSPEC = "Name:%String(MAXLEN=100),AltName:%String(MAXLEN=100)") [ SqlProc ]
{...}
Is there a way I can specify the MAXLEN by a function or a calculated method?
Like maybe:
MAXLEN=#(..GetLengthName())#
Or is this something that has to be hardcoded in Studio?
Hi Community!
New video "Choosing a Shard Key" is available now on InterSystems Developers YouTube:
Hi I'm just trying to make sure I'm not missing a trick here.
Basically our PAS doesn't do hl7 messages but does some XML which you can create. So I'm just trying to create some xml files and then get healthshare/ensemble to parse them and to process accordingly.
I'm getting some good results doing this. But maybe I've got a small hitch. In each of my xml files I've the data for the patient/client.
Hi,
I am running terminal on Cache on a Mac High Sierria and going through the ObjectSript tutorials.
However there is no instruction on the Intersystems website as to how to open Studio.
Does anyone know how this is done?
Thanks
I"m doing a SQL insert in my BPL, one of the fields in my SQL table is an MSSQL TimeStamp. How do I get the date/time from my HL7 message and format it so that I can then insert it into my TimeStamp column in my SQL table? I've tried lots of different combinations.
I used CONVERT(DATETIME, substring(:request.GetValueAt("EVN:RecordedDateTime"),1,8)) to get just the date portion and it works, but I'd like the whole DateTime inserted into my TimeStamp field. This is an a BPL.
Thanks
Hi Community!
I'm pleased to announce that InterSystems IRIS is available on Microsoft Azure Marketplace!

→ InterSystems IRIS on Azure Marketplace
This is the second public cloud offering of InterSystems IRIS after recently announced Google Cloud Platform support.
I followed the First Look instructions and tried to run a Docker container with the below command:
> docker run --name iris --detach --publish 52773:52773 --volume /Users/docker:/external --env ICM_SENTINEL_DIR=/external iris:latest --key /external/iris.key --before "/usr/irissys/dev/Cloud/ICM/changePassword.sh /external/password.txt"
It returned with a container ID and an error message:
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/iris-main\": permission denied": unknown.
Does anyone know how to loop through a segment that is part of an ordered set in a Business Rule and if one of about 10 possible values exist in any of the iterations of the segemnt:field I then allow the message to be skipped?
It seems like it should be fairly simple, but i am having a difficult time figuring this out. The Contains function only allow for one value to be identified. I have tried the intersectsList and while I think I have it formatted correctly i believe it only allows for 4 values to be verified.
How can I change Ensemble's time from UTC to local? For example, I want that time in the message browser and event log to be local, but now it is UTC. I tried to find some setting around management portal but couldn't find it.
Hi Everybody!

Where can I find CSP file in TRAKCARE. Seems i can find js file only but not CSP file in TRAKCARE T2017, may i know the path where store the CSP files? Many thanks.
Good afternoon everyone,
I hope you are well,
I am currently working on the below opportunity and if anyone here would like to hear more details please feel free to contact me on 01908 886 030 or teo.rusu@identifiglobal.com
or "Bonus Breakage"
In our last lesson, we added a relationship between 2 persistent classes. We are clearly going to need to start creating REST Services to expose CRUD operations for each of these classes, but before we do that, we should really finish defining our linkages. We added code to our Widget toJSON to spool off related Accessory data, so we should really do the reciprocal and allow Accessories to return all Widgets that are compatible.
Hello Guys,
Can you please guide me to create a RESTful API service in our cache (using intersystems cache kit) with CSP (Cache Server Pages ) object script.
