I’ve been using Oracle’s Zero Downtime Migration (ZDM) tool lately, and given there are still some limitations on cloning your database in OCI, I was thinking could we use ZDM for this? Short answer – for sure! If you want to use native OCI capabilities for cloning your database, you are limited on restoring the…
Remote Cloning OCI DBCS PDB with OCI CLI
In previous post I showed how to perform remote clone with Resource Manager/Terraform/Ansible. What if you just want a quick remote clone to be done manually? Remember OCI Console doesn’t support Remote Cloning at the moment (February 2022) but you can do the remote clone through API’s as well. So let’s do it with OCI…
Remote Cloning OCI Database PDB with OCI Resource Manager, Terraform and Ansible
Code referenced in this post can be found from my Github page. There’s a new feature in OCI, which enables you to remote clone PDB from one database to another if certain conditions match. Right now, the databases need to be in same Availability Domain, need to be in same version and use the same…
Autonomous JSON Database with Database API for MongoDB
Oracle had announced Database API for MongoDB which can be used together with Autonomous JSON Database. This post will be with some learnings what I went through when I tested it out. Official announcement post goes through the setup rather well. When provisioning the database, remember to select Autonomous JSON database as DB type and…
OCI Private DNS Design for multiple Regions
I’ll start by saying that typically I still see private DNS setup in the customer domain rather than in OCI, but recently I had a case where customer wanted OCI to manage specific internal sub-domain which we then used in the OCI Load Balancers. For that, there was conditional forwarders setup on-premises with a rule…
Exadata Cloud Service scaling (adding nodes) hangs
This will be a short post, mainly just to guide where to look if you ever encounter this issue. Recently I was tasked on adding a database node on Exadata Cloud Service X8M. The new X8M has dynamic deployment options so if you need more storage or compute power for your database nodes, you can…
Go Bastion(less!) on OCI
Update May 31st, 2021 – Seems like there was documentation bug so I’ve updated part about Agents. They are disabled by default so you need to enable them always if you want to use Bastion Service Managed session. I’ve always had slight dislike on requiring Bastion (Jump) server on any cloud which is self-managed. Sure,…
OCI Dynamic Routing Gateway Attachments Part 3 – Remote Peering Connections
Continuing use cases for new Dynamic Routing Gateway v2. This time I’ll look on Remote Peering Connections (RPC) and how that works together with DRG’s. Earlier posts on DRGv2 are here: Part1 & Part2 In short hardly anything changes, you obviously need VCN on some other Region which you want to connect to another VCN…
OCI Dynamic Routing Gateway Attachments Part 2 – Dynamic Route Import Distributions
On part 1 of the DRG version 2 we looked on basics and how you can control which VCN can be accessed and how, regardless if the source is through FastConnect, VPN Connect, VCN or Remote Peering Connection (another DRG). This time we’re gonna look on dynamic route import distributions. Since each VCN attachment can…
OCI Block Volume Replication Part 1 – Basics
Let’s talk about new OCI Cross-Region Block Volume Replication! I wanted to test this feature out as it can provide much needed help when you need to build your Disaster Recovery environment on different Region. In earlier cases we’ve used rsync for this, one great advantage with this new feature is that it uses Oracle’s…
