I bet few years back folks didn’t expect that by 2024 we would be able to provision OCI resources in other clouds. Last year the announcement for Azure and this year announcements for GCP and AWS have been really exciting and I think long term they’ll have a positive impact with Oracle’s reputation also. One…
Thoughts on Oracle Database@Azure
This will NOT be a technical walkthrough on Oracle Database@Azure but rather my opinions and thoughts on how it will shape the Oracle workload destinations when migrating out from on-premises. Once I get few technical implementations under my belt, I’ll also write some more details on how I see it works and how we need…
OCI ExaCS Database Upgrade Rollback
Recently I was testing OCI database upgrade from 12c to 19c and ran into an issue I wanted to fix.

WORM compliance with custom OCI Database backups
When you move your databases to cloud, many times the (current) standard backup configuration what Oracle offers is not enough. That’s when you configure OCI Cloud Database backup module which allows more flexibility with your RMAN configuration and also allows to write backups to custom Object Storage bucket. Question came up regarding this, can we…
Basics of Autonomous Migration with ZDM and integration with CPAT
This will be my third post on using Zero Downtime Migration (ZDM) for your migration, previously I’ve written about physical offline and online migration. Since Oracle talks a lot about Autonomous Database, let’s look this time what options you have on migrating to Autonomous. For Autonomous we have two options, logical offline and logical online…
Data Guard migration with ZDM
In the previous post I showed how to setup cloning or migration using offline physical option with Zero Downtime Migration (ZDM). This time let’s take a look what happens with ONLINE PHYSICAL option. Common migration requirement is to migrate with lowest amount of downtime and with all the latest data available and Data Guard is…
Oracle Database cloning in OCI – with ZDM!
I’ve been using Oracle’s Zero Downtime Migration (ZDM) tool lately, and given there are still some limitations on cloning your database in OCI, I was thinking could we use ZDM for this? Short answer – for sure! If you want to use native OCI capabilities for cloning your database, you are limited on restoring the…
