I am working on an angular applications and build a web application (Rest API) on IRIS for health, the web application uses a password authentication and setup with the default csp session time out (15 minutes). If the user make an REST API call from the angular application after the session expired, it displays a login prompt...is that anyway that we can disable the login prompt and just simply return http status 401? When the angular application received the status 401, it can redirect to angular error page.

Thanks,

Hoi

Hey everyone.

I have noticed that my backup mirror is warning that the MirrorDatabaseLatencyTime is having a bad time (time in ms is 3000, and warnvalue is 3000). While I look into what may be causing this latency between the two servers, I was considering if reducing the size of the journal files would improve this value in any way.

My assumption is that reducing the file size would mean that the frequency of the journal files being created would be increased, but the reduced size would mean that the transfer and application of each file would be reduced.

Hello All,

I am just wondering if there is any inbuilt function or utility available in IRIS to clean up "null" elements from JSON e.g. I want to remove "null" elements from payload below before I do any processing with it.

recipients: [

{ "name":"Utsavi", "email":"utsavi@gmail.com"},

{ "name":"Utsavi 1", "email":"utsavi1@gmail.com"},

null, null

],

content:[null, {"title":"Test.pdf", "data":"ygwehfbnwfbhew"} ]

}

Thanks & Regards,

Quite a complex scenario we are trying to solve but should be able to understand.

We're developing a task executer that runs on a server with a certain timezone.

The tasks run every day at a defined time, but in different timezones.

We're saving in database at what time we want to execute the task, and in what timezone (don't go to the save in UTC pitfall, as with DST it will be at different times)

What I want to do if when opening a task from the database, convert 02:00 Europe/Madrid, either to UTC or to local (server) time.

We have a stored procedure with one input parameter and one input/output parameter.

declare @hl7message nvarchar(max) = 'Pass the hl7 message here',
@output nvarchar(max);

EXEC sp_InsertHl7 @hl7message, @outputresult = @output OUTPUT;
print @output;

@output value will be "Pass" or "Fail"

Below code is inserting the HL7 successfully into the target DB, but not returning the output value as expected.

Hello,

I am wondering if anyone can help me with an issue we are facing. We are trying to add a parent-child relationship between 2 tables in the database that already contain data. We are able to add the new relationship property to the required data classes, and set the desired cardinality. We have also included code that will add the relationship using the Insert() method to new data that comes in.

The problem we have is how do we add the relationship to data that already exists in the database?

I have successfully created REST service classes on my local IRIS server following this book: Using the /api/mgmnt/ Service | Creating REST Services | InterSystems IRIS Data Platform 2021.2

I am now 1) trying to edit impl.cls in VS Code and 2) export it to my local repo so I can push to the remote repo.

When I click on my project in VS Code and 'Add to project' and choose the new package, spec.cls and impl.cls, I get the following error:

Following "Adding Custom HL7 FHIR packages to the HL7 FHIR server" at https://learning.intersystems.com/course/view.php?id=1721 I'm able to create an FHIR extension of type string as well as a search parameter.

However, I need to create an extension as well as a search parameter of type Reference. And this is not working.

Did anyone successfully add an extension and search parameter of type Reference?

We have a scenario where an ObjectScript-based production calls a lookup service (SOAP in C#) to get information used in a value-set mapping process. The results can be cached in an IRISTEMP global to prevent a network call for every value, but that can hang around for quite some time on production systems.

The next logical step would seem to be to encapsulate strategies (LRU, MRU, etc.) and eviction code into an ObjectScript class that can be reused (we are not in a position yet to leverage embedded Python).

Hi folks!

Researching FHIR bundle transactions.

The idea is that you can post a bundle to a FHIR server with a set of resources. And you can send it as a transaction, so only all the resources will be published or neither.

E.g. I send a bundle of two resources: patient and its observation.

The observation resource should reference an existing patient. But it probably doesn't exist yet on the server and goes within the same bundle.

For this purpose there is a way to have a temporary id in the bundle, to let resources reference ids.

Curious if anyone has modified the HL7 TCP/IP Service and adapter class to receive an HL7 message, ACK it, and just dump it straight to a file? I don't want the messages in the engine at all - just receive and dump. Has anyone done this before and have code you're willing to share?

Thank you very much in advance!

Hi,

I'm trying to figure out why I'm unable to iterate through a dynamic array and access the nested objects.

Using the NHS PDS FHIR API in the NHS sandbox environment, I'm querying the PDS endpoint using a sample NHS Number to retrieve a patient's demographics. My Business Operation reads the response data and passes it back to my Business Process where I intend on iterating through certain nested objects. The data present in these nested objects will decide what happens next in the process.
