Last time I showed how to provision Autonomous Database Serverless (ADB-S) on Google Cloud. This time I have provisioned a new ADB and want to see how I can connect from my VM running on the same VPC as the ADB. I’ll use sqlcl to connect to the database, to install it you will need…
Can you believe it? Provisioning Autonomous Database in GCP!
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. I was doing this via dbaascli (on Exadata) and the upgrade hit Bug 34455245 – db12c upgrade to 19c fails with ORA-600 [kxhfmgetextent.1] (Doc ID 34455245.8). I tried few things as with dbaascli you can…
Issues with OCI ExaCS PDB cloning
This is mostly just to document if you hit similar issues and how to get past them. I had to perform some remote cloning in ExaCS (from one CDB to another CDB) within same VM cluster, but hit few issues which I had to resolve first before getting it to work. [DBT-05514] Failed to connect…
OCI Tips and Tricks – Managed MySQL Database in OCI (and trying out Heatwave)
Here I’m looking on how to provision MySQL DB on OCI, see how read replicas work and how to add Heatwave Cluster to your DB. After that, I’m running some test queries to try out Heatwave, interesting results!
OCI Tips and Tricks: Create 19c Oracle Database (and manage it)
This time I go over on how to create 19c Oracle Database on OCI (hint: It’s super easy!). But what I feel is more important, where to find relevant log files after you’ve provisioned the database and how to use dbcli to manage your database and debug issues. Hope you enjoy the video!
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…
