23 Free won't start listener

[khooz]

Since the rebranding from 23c to 23ai, the older image has been removed and a new one made available. I had initialized a single-instance DB using the old image. Unfortunately I used the latest tag. When I started k8s on docker desktop after the rebrand, I noticed the new image has been pulled but it won't. I used kubectl describe and log commands and found out the following statements:

PS C:\Users\Admin> kubectl logs -f pod/oracle-db-5b1bm -n database
Defaulted container "oracle-db" out of: oracle-db, init-permissions (init), init-prebuiltdb (init)
Starting Oracle Net Listener.

I have deleted the contents of the PV and restarted the pod. It created a new instance and is now running. How ever I have lost my data. It was OK with this test environment but I think an autonomous upgrade path should be incorporated into images. Also digging through the alert logs I have noticed that domain name is predefined. Is there a way to join or initialize a DB to a domain so it could be monitored through cloud control?

[yunus-qureshi]

@khooz which domain name are you referring to here? and what is it pre-defined as?

If the database wasn't configured to use a persistent volume for its data, dropping/recreating the pod deletes the data. This is true of any database, not just Oracle. :)

Thanks @oraclesean

I have manually setup the PV to be retained. as you can see here:

It was working fine with image using 23c as brand (which is not available in the repository now). I have deleted and re-applied multiple times using the same image and PV before. I can do it now with 23ai too, but it seems there were no interoperability or upgrade path available.

[yunus-qureshi]

This is expected. There is no upgrade path for Free DB releases. Upgrade and patching are only supported with Enterprise edition.
