Various thoughts on Oracle, Enterprise Architecture, Cloud Computing, Kubernetes and everything Storage
Background So, the time has come to migrate your Oracle database to another storage array. There are a number of different options available to us, including the Oracle online datafile move, Oracle Recover Manager (RMAN) backup/restore, Oracle DataGuard failover, Data Pump, GoldenGate, host base mirroring, storage replication to name just a few.

In this post I will share how you can get started with containerising Oracle databases and how to use a Kubernetes Container Storage Interface (CSI) driver to provision dynamic persistent storage to the container. For this post I will use Oracle 18c Express Edition (XE) the 'Free Database for Everyone' and Portworx Essentials Forever Free... Continue Reading →

Introduction If you thinking about, or already running an Oracle database within a container, you may have thought 'how I am I going to backup and secure my database and environment ?' In this post I will share how we can use Portworx PX-Backup to easily backup an Oracle database to a Pure Storage FlashBlade... Continue Reading →
I have previously shared how we can deliver a containerised Oracle 19c database using a Kubernetes Statefulset with Block devices, in this post I will show how we do the same with Kubernetes Deployments and NFS. For this post I will be using Kubernetes v1.17 [root@master-1 ~]# kubectl version --short | awk -Fv '/Server Version:... Continue Reading →

Autofs, also known as automounter mounts filesystems on-demand when they are accessed rather than maintaining the mounts all the time. The... Continue Reading →
Introduction Last year I wrote a number of posts on Big Data and shared how we can access CSV, Parquet and Avro file formats directly from an on-premises Oracle 19c database using Oracle external files on a local file system or and NFS share from an NFS server e.g. FlashBlade Unfortunately, at that time I...

Introduction In my post How to access Object Storage from your on-premises database I showed how we configure an Oracle 19c (19.9+) database to use the DBMS_CLOUD package to access objects stored within Object Stores. In this post I will share how I created the Oracle Cloud Infrastructure (OCI) Object Store bucket and objects I... Continue Reading →
Introduction Last year I wrote a number of posts on Big Data and shared how we can access CSV, Parquet and Avro file formats directly from an on-premises Oracle 19c database. In these posts I demonstrated how we can access different file types using SQL external tables on a file system, unfortunately I quickly run... Continue Reading →
