Database In-Memory Base Level Feature Now Available in Oracle 19c (19.8.0.0.0) Release Update (RU)
Database In-Memory Base Level Feature Now Available in Oracle 19c (19.8.0.0.0) RU
The Database In-Memory Base Level feature is now available for Oracle Database 19c! Support
for the Base Level feature was added to 19c in the just released 19.8 RU.
As a brief review, with the Base Level feature you can use up to a 16GB column store
without having to license the Database In-Memory option.
This now gives anyone running Oracle Database 19c Enterprise Edition the ability to try
out Database In-Memory for in-production workloads, without having to license the
full Database In-Memory option first.
Simply apply the 19.8 RU and set the INMEMORY_FORCE initialization parameter to BASE_LEVEL and
set the INMEMORY_SIZE parameter to a value up to 16GB. When you restart your database,
the Base Level feature will then be enabled.
That's really all there is to it.
Oracle Database In-Memory will now have a "Base Level" feature.
This will allow the use of Database In-Memory with up to a 16GB column store for no extra cost.
That's not a typo. Database In-Memory will be free to use with up to a 16GB column store!
Note: Apply July 2020 RU to get Oracle 19c (19.8.0.0.0)

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.2.130:6443 --token a8a9vc.dk8krmn838is5gy6 \
