Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Hello,

I have a quick question regarding TSTART, however not certain if there is an answer.

If I am inside the transaction and I loose connection - I always assumed that transaction would TROLLBACK, however it does not.

Is there anything special I need to set up with my TSTART, in order for this transaction to safely rollback?

*********

As example: Let's say I am inside the TSTART and setting up / altering some data and my VPN connection got disconnected. I kind of expect all the data to be rolled back.

Thank you,

Alex

Team,

I am trying to use Visual studio code(1.57) for class development and for compiling classes (intersystems tools extension) . It works.

Now, i would like to use TFVC (Team Foundation Version Control) for source control.

I can see download option where i can manually download the Namespace as folder and classes as files.

Since whenever i save the file, it directly pushes the change to remote system. I am not sure where the local workspace is.

How to configure VS Code to track my changes and Check In / Check out the code.

Hello Everyone

I am new to cache. I know there are 2 types of methods in cache. One is Instance method (Which can be call through object creation of particular class) and other is Class methods (which can be call through ##Class(MyPackage.Car).CarModels()).

I want to know the difference when to create a instance method vs when to create a class methods.

Thanks in advance!!.

embedded sql select locks

i noticed -by reading .INT files of one class- that some of embedded sql select statements code blocks translates into code that uses lock command.

even if i use %nolock in the select, still cursors and arrow referencing notations "->" have the same results.

Hi everyone!

I am trying to localize text in an XData block using the $$$Text macro. A snippet of code is included below. Is there an easy way to localize the text included in an XData block? So far, using the $$$Text macro is not working; when I export the %MessageDictionary, the text to be localized isn't included in the export.

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are:

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

I am not sure if this is the correct place for this question, but I am struggling to setup TLS security for our IRIS Management Portal and etc. through Apache and the Web Gateway. I have a couple of questions when it comes to the setup.

  • if I build a private key and certificate within Red Hat, does that certificate have to be on everyone's pc to connect to the Management Portal?
  • Can I use a self signed Certificate?
  • Can I use the existing CA on the server, or do I need to work with my Data Security team to get a Certificate?

using SSH to connect to IRIS

Has anyone here successfully connected to a community edition version of IRIS through port 22 to localhost? I have been trying for hours and hours to connect a Mobaxterm terminal session to IRIS and am at a total loss. Im not sure if port 22 isnt opening at this point or if its a configuration issue on my part. I am seeing either "Remote side unexpectedly closed network connection" or "connection refused" when i try to run the SSH session. I have tried 22/51773/1972 etc port settings under add/edit server to no avail. Any help is appreciated. Thanks.

From IRIS log, I found lots of following content

05/05/22-01:05:11:375 (16166) 0 [Generic.Event] ECP: Mirror Connection request from 'SM25SDLMIIRROR:LOCALHOST.LOCALDOMAIN:IRIS' (10.xxx.xxx.27:33040)

05/05/22-01:05:11:376 (16166) 1 [Generic.Event] ECP: Active server not defined, cannot redirect mirror connection

Could any one explain a little bit for me?

I want to embed the DTL editor in a third party web application.

If I open up the DTL editor then the full management portal banner is displayed.

http://localhost:52773/csp/healthshare/user/EnsPortal.DTLEditor.zen?DT=Foo.NewDTL1.dtl

If I open the same DTL in studio then I get just the editor, the banner is not displayed.

The DTLEditor page has the property studioMode that controls the banner display, but its not obvious how this is set.

Hi team,

I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?
