Oracle Cloud Infrastructure – Configuring Network Access with Access Control Rules (ACLs)

When running Autonomous Databases (ADB) in Oracle Cloud Infrastructure (OCI), it’s crucial to prioritize security, even for development and test environments. Allowing unrestricted public access (0.0.0.0/0) is not a secure solution and should be avoided. To ensure that only trusted sources can access your databases, you can restrict access to specific IP addresses and Virtual Cloud Networks (VCNs). To enhance security, I configured my ADB to allow access only from specified IP addresses and VCNs. This approach ensures that only authorized users can connect to the database. My next step was to add the public IP address of my workstation to the ADB’s access control rules, so I can securely manage the database from my current location. While the OCI…

Never stop Learning – why I love Oracle LiveLabs

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…

The Grafana Plugins for Oracle Cloud Infrastructure Monitoring are back!

In September 2019 I wrote a blog post how to monitor an Oracle Cloud Infrastructure Autonomous database with Grafana plugin oci-datasource. But some weeks after publication, the plugin was not available on the Grafana page anymore. And only Oracle and Grafana had a clue why. Now everything will be fine now. Since the 6th of October, there are two new Grafana plugins available for download. They both don’t require a Grafana enterprise account. Oracle Cloud Infrastructure Metrics Data Source Oracle Cloud Infrastructure Logging Data Source The first one is a successor of the former oci-datasource plugin, the second allows to get logs from OCI resources like Compute or Storage. As an infrastructure guy, let’s install the Oracle Cloud Infrastructure Metrics…

Oracle Cloud Infrastructure – Network Troubleshooting with VCN Flow Logs

Do have a problem with a connection from or to your private/public subnet? There is a new functionality called VCN Flow Logs available. It collects information about network traffic (source/target) in the Oracle Cloud Infrastructure VCN subnet. At the moment (05/03/2020), this functionality is not available in all regions and I did not find any command in OCI CLI, but will be rolled out. There is no documentation available at  docs.cloud.oracle.com. Link to the OCI blog announcement and demo: https://blogs.oracle.com/cloud-infrastructure/announcing-vcn-flow-logs-for-oracle-cloud-infrastructure LA I have registered our company tenant for the Cloud Native Limited Availability Program to get this brand new feature available. Watch here: https://blogs.oracle.com/cloud-infrastructure/announcing-limited-availability-of-oracle-cloud-infrastructure-logging-service Use Case A public compute instance with private IP 10.92.10.2 is not able to connect to…

MV2ADB – One-Click Move of your Data into OCI Autonomous Databases – Auto Operation

In the previous blog post MV2ADB – One-Click Move of your Data into OCI Autonomous Databases – Step by Step I wrote about the new Oracle Cloud Infrastructure tool to transfer local data into Autonomous Databases step by step. There you see how to install and configure mv2adb and how to transfer your data to ADB step by step. The auto operation parameter is now “all in one”, one parameter and all required steps like export, transfer etc. are done fully automated. Prerequisites mv2adb rpm package installed, always get the newest version from My Oracle Support (Doc ID 2463574.1) HTTP/SQL*Net Connectivity from the on premises server to the Autonomous Database Autonomous Database Wallet (can be downloaded from the ATP main…
