Hey everyone,

I'm diving deeper into Caché ObjectScript and would love to open a discussion around the most useful tips, tricks, and best practices you’ve learned or discovered while working with it.

Whether you're an experienced developer or just getting started, ObjectScript has its own set of quirks and powerful features—some well-documented, others hidden gems. I’m looking to compile a helpful set of ideas from the community.

Some areas I’m especially interested in:

Hi There,

I'm fairly new to ObjectScript/Ensemble and I'm sure I may be fundamentally misunderstanding how the %JSONImport/%JSONExport and XDATA mapping work and I was hoping you good folks could help me out. I'm essentially trying to create an object that I can use to translate from one JSON schema to another.

First my class:

Is anyone using the IPM client (e.g., running commands like zpm "install somepackagename") on an IRIS version earlier than 2022.1?

We're thinking about raising the minimum supported version so we can use Embedded Python in IPM. I'm curious if this would impact anyone. Of course, you'd be able to continue to use an earlier version of IPM.

To transfer data between production components I actively use messages of type Ens.StreamContainer class and its descendants. In many cases the content of the message content is not visualised (the 'Body' tab contains a table with a list of selected message properties but the 'Contents' tab is empty). Response messages are never visualised, and request messages are visualised with a fifty-fifty probability. What do I need to do to ensure that messages are always visualised?

We just upgrade from cache 2016.2 to IRIS 2020.1.1.

After this upgrade we cannot access to the portal web management, and dont give errors about that just this:

09/28/21-15:59:16:654 (20192) 1 [Utility.Event] Private web server has not started after 5 seconds.

Is this normal?

I followed the guide but dont talk nothing about that.

This is a normal problem when upgrading?

Thanks!!

FTPS TLS session resumption

We are attempting to update some old FTP interfaces to use FTPS and having an issue with an outbound operation to a FileZilla server.

The connection to the the server works, however it fails to transfer files with the error "TLS session of data connection not resumed."

It appears that "TLS session resumption" is no longer optional in FileZilla Server, and I cannot find any details in the IRIS documentation about it.

Does IRIS support TLS session resumption, or know how to set up FTPS to a recent install of FileZilla Server?

Good morning. Perhaps someone can tell me if this IRIS health communit version (IRISHealth_Community-2022.1.0.209.0-lnxubuntu2004x64) is supposed

to work in an Ubuntu 20.04 LTS installation in an Oracle Virtual Box .

I am trying to install different versions on Ubuntu . I tried with the 18 version. No luck. Than I've tried with the 20.04 version. No luck either.

The error I am having now is below

///////////////////////// error message from the install ////////////////////////////////

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!

Is anyone using Veeam as their external backup product?

I'm trying to backup a Linux VMs (VMWare; SUSE).

These VMs have a mirrored pair IRIS DB.

I'm using the InterSystems's provides pre-freeze - Backup.General(ExternalFreeze)
I'm using the InterSystems's provides post-thaw - Backup.General(ExternalThaw)

I've been running the backups with Veeam 'application aware processing' so I can add the pre-freeze and post-thaw scripts.

I'm backing up the PRIMARY node of the mirror pair.
