Hi [subscriber:firstname | default:subscriber],
|
Happy Friday! Now the previously mentioned Exa Flex shapes are here! You are not tied anymore for aspecific shape when you deploy your Exadata but can expand it afterwards by adding compute or storage nodes.
|
And it seems you can do it online as well, super interesting!
|
Check the Load Balancer post in the blogs section, much needed functionality!
|
|
Video will be available for watching later on as well.

New Features
|
Read details on Exadata Flexible infrastructure! At the same time it's also the only way you can provision new Exadata X8M shapes. If you're already using older X7 or X8 shapes switching to new resourcing model should be fairly simple.
|
|
Don't stop on the first page but read also the scaling part of documentation! Obviously I haven't ever done this but would be great to see live example how storage & compute nodes get added online.
|

|
|
Speaking of rolling updates, if you scale your DBCS RAC VM up or down the re-shaping is now done ONLINE. Each node will be rebooted in order so you don't need downtime for this activity anymore.
|
|
|
|
|
Another one, perhaps even bigger new feature is the Operations Insights. It gives you a good view on capacity and resource utilization of your Autonomous Databases.
|
|
|
|
|
As per documentation it simplifies application migration, workload rebalancing, and business continuity across data centers and clouds.
|
|
|
|
|
If you are creating compute instance, you can now create stacks for Resource Manager. In short it creates you Terraform config which can be used in Resource Manager. Don't know how to use Resource Manager, this gives you good way to start looking onto it!

Do you remember Autonomous Database on shared infrastructure (ADB-S) got Data Guard some time ago? Well now also Autonomous Database Dedicated (ADB-D) supports it!

This is pretty cool, it's about Load Balancer chaining in OCI - it doesn't seem to be mentioned much yet but you can actually give IP address as a LB target. I think earlier you could only use compute instance OCID / name as a target. Opens up lot of possibilities!

Question of the week
|
When does Load Balancer Health check give you Critical, Warning or OK status?
|
- It's good to remember Load Balancer and backend set health statuses are different! for LB:
- OK: All backend sets associated with the load balancer return a status of OK.
-
WARNING: All the following conditions are true:
|
- At least one backend set associated with the load balancer returns a status of WARNING or UNKNOWN.
- No backend sets return a status of CRITICAL.
- The load balancer life-cycle state is ACTIVE.
- CRITICAL: At least one backend set associated with the load balancer returns a status of CRITICAL.
What different methods of SSL handling do you have with OCI Load Balancers?
