Since over one and a half year, this week I was back in an onsite training, live people, live teaching. With a motivated junior DBA class, we started with all about Oracle architecture based on our Trivadis training O-AI – Oracle Architecture and Internals. The training is a mix between slides, demos and labs. Therefore during the course we run the training environments in Oracle Cloud Infrastructure, build by Terraform (Credits to Stefan Oehrli from oradba.ch which has ramped up the whole stuff). After the course at the end of the month, the environments will be cleaned up. And what’s next? Training Environments There are a lot of possibilities to get a deeper knowledge of all this Oracle stuff like…

MV2OCI – One-Click Move of your Data into Oracle Cloud Infrastructure Database
mv2oci is a tool which helps to migrate on-premise data to the Oracle Cloud Infrastructure based on Oracle Data Pump and works as a data load tool. The local Data Pump export is transferred and imported to/on the target cloud server automatically. There is no use of Oracle Cloud Object Storage, the dump files are transferred with rsync or scp to the target database node. This is the different behavior to mv2adb – see my blogpost here – which uses the Object Storage. As an option, the data can be transferred via Database Link (mv2oci Parameter –netlink). All you need to know about mv2oci is written in the My Oracle Support Note (OCI) MV2OCI: move data to Oracle Cloud Database…

Read MoreOracle Cloud Infrastructure – Security first: Cloud Guard and Security Zones – a first View
Two new Oracle Cloud Infrastructure Cloud Security Services Good news: Oracle has provided two new services for cloud security. Cloud Guard to get an overview of existing possible security breaches and Security Zones, which allows to create a full restricted compartment. In this blog, I will give you a short overview about this brand new services. Cloud Guard The Cloud Guard service helps you to identify security issues in your tenancy. Before the first use, it has to be enabled and a base region and for a minimum one compartment has to be selected. It needs a new policy which Cloud Guard allows to gather information in your tenancy. Oracle Cloud Guard discovers available object in compartments like Compute Instances,…
Read MoreOracle Cloud Infrastructure and SSH Keys – Jump!
Jump! In our Trivadis Oracle Cloud Infrastructure training environments, we never use direct access to an application or database server by a public IP address. For this case, we use an Oracle Linux based bastion host which acts as a jump host. For security reasons, I never put any SSH keys on a bastion host to connect from there to the target instances. If your bastion host is compromitted, your SSH keys are lost! In one of the last trainings, some participants had problems with. So I decided to blog about. This blog post shows you the different methods to connect to an Oracle Cloud Infrastructure private/public network by using a bastion host. SSH Keys Oracle Cloud Infrastructure Linux based…
