Mirrored Oracle Error
Hi v-kpoloju-msft,
thanks again for your reply. I've already been in contact with the fabric support team and they confirmed that the error I'm getting results from the amount of tables ~10000 that are in my database and they cannot be displayed. So this is just a UI error that can be circumvented by creating mirror items via Rest-API.
Thanks again for your help!Best regards
Hi moritzbartram
Thanks a lot for sharing that log detail that helps narrow things down.
The CommunicationObjectAbortedException message suggests that the connection between the Fabric mirroring service and your on-premises gateway was unexpectedly closed during setup.
Since your gateway, region, and Oracle client versions all look correct, this is likely a transient connectivity or service-side timeout rather than something misconfigured on your end. Please try the following next steps:
Ensure outbound HTTPS (port 443) traffic from the gateway machine is not being filtered by a proxy or firewall.
Try creating the mirror again in a different Fabric workspace or with a new gateway connection just to rule out any workspace-level issue.
If the error continues, I would recommend raising a Microsoft Fabric support ticket so the team can review backend traces and confirm if this is a Fabric-side timeout.
