InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
Now I want to return a large amount of data to the front end. The string length has reached 40000 +, and the returned data needs to be encrypted by AES + Base64. I can convert the string into a stream. AES can use the AESCBCEncryptStream method to encrypt, but Base64 has no stream method。Anyone who get the solution would you kindly share the solution please。
I have a %GlobalBinaryStream object that I'm trying to save as a local file after being received through a SOAP Web Service.
To do this, I created a %Stream.FileBinary object and wanted to set where the stream copied to this object would be saved by using either the DefaultStreamDir() ClassMethod or the NewFileName() ClassMethod. However, the documentation isn't very helpful on how to use these ClassMethods.
I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.
Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.
From looking in the class, the %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.
I am trying to replace one of our SQL Integration Service jobs with Ensemble and I am running into an issue executing a query against a MS SQL database using JDBC drivers.
I have an auditing class that defines some sqlComputed properties and can be extended by other persistent classes to enable auditing of its properties.
We have a use case whereby very large HL7 MDM messages, which contain many OBX segments, need to be processed by a custom business process. Part of the process is to iterate over each OBX segment and set a value in the same field for each segment.
We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?
Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.
OAuth server to be deployed on the IRIS learning cloud platform. Clients - one on the other instance of the learning IRIS server, the other client locally on my computer in the container docker.
Both clients get a seemingly correct link (through ##class(%SYS.OAuth2.Authorization).GetAuthorizationCodeEndpoint()) to the login request form:
I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.
Sorry, somewhat of novice here, but how is a mac or a routine created into a binary or is there a way to hide your routines so that no other user can edit them? Like remove source code and have an executable?
We are in the process of migrating from Ensemble to IRIS.
After the migration I would like to find all usages of deprecated classes and methods in all of our code. This is to align with the changes in package like %SYSTEM.SQL for example.
Is there an easy way to do this, or maybe a tool that can assist?
I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.
So, how can I do this, without losing performance, there is any way?
I need to perform some processing-heavy operations on a set of input objects and I would like to utilize more than a single processor core to do the heavy lifting.
Is there any way to call methods in parallel and wait for the results in a blocking way?
Basically, I am looking for an equivalent of the pythonese
with Pool(n) as p: results = p.map(function, data)
I was wondering if there is any way to count elements from an array. I guess not as an array could be multi-dimensional and that would be a problem to return the number of elements inside the array.
I am trying to do a basic read file of HL7 messages. Need to count how many FT1 segments are there in each file and how many messages are in each file.
Any help will be appreciated. I have the stream object.
Just need to loop through the stream and get the info in some way.
I have a class method that accepts a global parameter but when I attempt to order this global, the global name is listed as undefined. I can execute $DATA(pGlobalName) successfully.
