The blog was supposed to be a small how-to but it has grown to a bigger one and hopefully might help to avoid some minor problems while exporting data from an Autonomous Database (ADB) in Oracle Cloud (OCI). It is about exporting data to the Oracle DataPump format to move data to another database or as a logical “backup”.
Oracle documentation provides sufficient information but I find it more and more difficult to navigate considering the number of options and flavours for Oracle databases. There are some new ways and tools around Oracle OCI ATP which can help in some cases. If you want you can jump directly to the end to read the summary.
This blog was primarily driven by questions from my peers and colleagues who wondered where my blog was hosted and how it was created. It might help to move from a hosting platform to your own website and where to start.
Like most bloggers I started my blog using one of the hosting platforms but soon after found some limitations in choosing appearance, plugins and was a bit annoyed by some commercial banners on my page. After a while I decided to move to my own site. I bought a domain name for myself and created my own environment using the WordPress software on a cloud VM. It didn’t cost me too much but it was not entirely for free. When Oracle introduced some additions to the always free set of resources. I decided to give it a try and move my blog entirely to the OCI free tier.
For those who would like to skip the reading and try, I have a set of Terraform scripts on GitHub. They haven’t been updated lately and use not the latest versions but can be a good place to start.
I see more and more Oracle databases are moving to the public cloud or to a hybrid cloud solution. Depending on the platform, size and used options it could be a different path but the general approach boils down to three main options – Oracle RMAN backup and restore, Oracle Data Guard or Oracle Data Pump with or without transportable tablespaces. Here I want to share our approach for migration from 12.2 standalone database to 19c RAC container as PDB in the Oracle Cloud Infrastructure (OCI).
Oracle Database as a service (DBCS) on Oracle Cloud Infrastructure (OCI) had been traditionally built based on Oracle Grid Infrastructure with ASM as the main storage layer for the database, however Oracle recently has started to offer a Linux LVM as the storage alternative. Which option is the better alternative? Let’s review some of the differences between the two options.
This blog post is bit longer than usual but I wanted to cover at least three options to upload files to the Oracle OCI object storage. If you need to just upload one file you can stop reading after the first option since it covers probably most of needs to upload a single file. But if you want a bit more it makes sense to check other options too. Continue reading “Copy files to Oracle OCI cloud object storage from command line.”
For some time we didn’t have a multi-factor authentication in the Oracle cloud and those short-lived numeric codes were one of the best way to reinforce your protection and prevent a bad actor to break your credentials. It is not 100% protection but it is well better than a username and a password. Just recently I read in the Oracle Infrastructure cloud blog about new native multi-factor authentication for Identity and Access Management (IAM) system on Oracle Cloud Infrastructure (OCI). Of course, I went directly to my account and started to test it. Continue reading “Oracle Cloud Infrastructure multi-factor authentication”
