This question is about calling AWS REST APIs. Based on:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck.  Here comes the question:

Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?

Thanks,

Chris

Hi all,

This might be a stupid question, but I'm going to ask it anyway. 

My goal is to write a scss file, pack it as part of a local library (Something like my_library.tgz), npm install that library into a different project and then import that scss file in one of the scss files in the new project.

Simply having the scss file exist in the library before I pack it didn't seem to work; the file wasn't under node modules after the npm install.  Am I doing something wrong, or are there extra steps I have to take?

Thanks in advance.

Update:

1. Still don't know what a foundation production does?  What does Ens.Activity.Operation.Local.cls do?

2. Why does creating additional namespaces in 2019.1 causes foundation productions to be created automatically
(with Ens.Activity.Operation.Local operation).  I can't run a foundation production and a routing production in the same namespace. (no change from 15.03)

I am integrating with Front End using ODBC to the Caché tables.

I have a property of type %Library.Time in one of the Caché classes FrontEnd which is in C#, it is not possible in C# to represent only a Time type, it always has a date as well (DateTime type, no Time only in C#), but that is fine, should not be a problem, so for Time the date simply defaults to 1900/01/01. 

Now when this is sent to Caché it does not like it and I would like to understand why because this is causing us not to be able to use a Caché property of type TIME ever.

Hi,

I am sending a request message to Business Process which has one property as Dynamic Object type. So i get the JSON in my REST service and convert that as a dynamic object and set that in the request message and calling the business process from the business service. But the request is not getting sent to the Business Process. Is it possible to send dynamic object input to the business process.

As a normal IRIS user how can I view who's made changes to a process?  There are over 10 people on my current team and it would be amazing to be able to click on a process or rule and see who created it or who made the most recent changes.  I'm not seeing anything in the documentation.  Journaling doesn't seem to capture that information either.

We have in DB two books, first is loaned because it has the Friend ID, and the other is in the shelf.

I execute a class query to get all loaned books:

    Query BooksLoaned() As %SQLQuery
    {
        SELECT *
        FROM Library.Book
        WHERE Friend IS NOT NULL
    }
 

Which I have tested throught the portal:

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

  • all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
  • all values are integers so I don't have to think about URL limits
  • all values are atomic
  • all conditions are about equivalency

Some options I know of:

1. URL parameters.

Hi all,

Over the next few months I'm going to be setting up continuous integration via Jenkins for some Angular UI's.  The goal is to, on each build:

1. build the code

2. run the unit tests and get a report

3. get a code coverage report

Just wanted to poll the community in case someone else has already worked with any of this before.  All ideas are appreciated.

Cheers,

Johnny

I have the following message when I try to import a WSDL to generate a SOAP service:

 

ERROR #5319: The type of a property of a class series cannot be recurring: SeleneHL7Service.hl71.escapeType:escape
  > ERROR #5030: Error occurred while compiling SeleneHL7Service.hl71.escapeType class

 

I have found in the documentation:

 

 

5319 The type of a property in a serial class cannot be recursive: %1

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

I used the Activate wizard to create a package for Excel (Activate.Excel). There is a class in there that seems to be what we need to open a file:

Activate.Excel.Workbooks.

 

There is a method that  has an Open() command. I tried  using it but getting an invalid pointer error.

 

The  parameters are as follows:

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?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

We are constantly running into issues where there are billions of Orphaned messages in our system that cause problems, and we have to manually run a cleanup to fix performance issues.

 In the following article about orphaned messages... https://community.intersystems.com/post/ensemble-orphaned-messages it mentions either programmatically eliminating the Orphaned messages or using a Utility like Demo.Util.CleanupSet in ENSDEMO.

I am using Ensemble FTP adapter to monitor file directory for files that require SFTP transfer to remote server using public/private keys for remote server authentication.

This works great in my engineering development space where file protections are loose.

I want to apply "principle of least privilege" regarding the public and private key files specified in  FTP Outbound adapter Business Operation. 

Can anyone recommend (Linux) permissions that allow Ensemble to execute the SFTP operation but minimizing access to the key files?
