Options for improving stability of our OpenREM installation

[Xanthe Hoad]

Hi all,

We (UHS NHS FT) are currently running OpenREM v0.10.0 on a Windows 10 desktop PC using the built in DICOM store (not ideal but this is what we have at the moment). Our install is functional occasionally experiences downtime during which transfers to OpenREM from the units fail (usually one of the services stops running - often celery).

Do any of you have any advice/ideas on the best actions we could take to improve the stability of our install? Options we have thought of are:

- Move to a different DICOM store

- Upgrade to OpenREM v1.0.0b2

- Move our install from a desktop PC to a server (we hope to be able to do this but slow progress getting IT on board)

- Upgrade desktop PC to Windows 11 (we might have to do this if we don't move to a server - does anyone have any experience of this? any issues to be aware of?)

Which of these do you think would be most impactful? Any advice would be helpful.

best wishes

Xanthe

Dear Xanthe,

Upgrading to OpenREM v1.0.0b2 removes the need for Celery and the RabbitMQ messaging. It also completely removes the built-in DICOM store. I think your best action to improve stability is to move to v1.0.0b2 and switch to using Orthanc for your DICOM store. 

You should install the above on a test system first to make sure it works as expected before moving your live system to the new configuration.

Kind regards, 

David
