I have recently blogged about how to install and configure Dynamic Scaling as an Oracle Linux Service daemon. See my blog, https://www.dbi-services.com/blog/how-to-automatically-manage-ocpu-on-exacc-using-dynamic-scaling/ In this blog I would like to show how to configure it as an Oracle Grid HA resource. This is the way we decided to go with at customer site. This will be an installation on a 2…

In this blog I…

Quick recap : in the previous episode, we have seen how to move from a Kubernetes cluster powered by Docker into a future-proof Kubernetes cluster, using containerd. Now let’s move on and fully enjoy the power of having this CRI intermediate layer sitting below the kubelet. containerd and OCI runtimes containerd is a high level container runtime. It is CRI compliant,…
