If you’ve worked with Autonomous Database previously, you know that every now and then you need to get files from the Autonomous Database or put files to Autonomous Database so they can be processed. For example, when you migrate data using Oracle Data Pump, the log files will be placed on the Autonomous Database. Typically,…
ZDM migration to Autonomous Database on GCP using Network Link for direct migration – part 2
Well this took a while! With recent work and travel it’s been couple busy months. Excited to write on this after being at Google Next 25 last week! I really feel the Oracle partnership with Google, Azure and AWS is going to be awesome for folks who still leverage Oracle technology heavily but want to…
ZDM migration to Autonomous Database on GCP using Network Link for direct migration – part 1
This will be a weird and fun post. I have recently been working with Autonomous Database migrations and wanted to highlight the option of using Oracle datapump (ZDM Logical Offline) and network link option. Using network link removes the need to export the data first to cloud storage and allows you to import “directly” your…
IP Address Insights with CLI
My previous post on IP Address Insights I mentioned it wasn’t yet available with CLI but I was wrong! It was there, just my Cloud Shell CLI version wasn’t the latest so didn’t have the command yet available. If you have 3.40.2 and above, the following commands are now available: oci network ipam list-ip-inventory oci…
OCI IP Address Insights
Recently OCI announced small but VERY useful service, IP Address Insights. Why this matters? I’ve run into multiple issues where we have VCNs and subnets deployed and don’t have any visibility on how many IP addresses are currently allocated on given VCN/subnet and who’s also reserving those. Not too long ago, someone reached out to…
OCI Network Firewall – Real World problems
I recently hit an issue with OCI Network Firewall that we had configured with NAT GW (see previous posts on it). We expected only to use it for egress traffic from OCI to public internet from our private compute VMs but a new requirement came which required to access some privately exposed services on OCI,…
Installing OCI Network Firewall – Allowing traffic via policies
Now that we have designed and installed our OCI Network Firewall we’re ready to allow some traffic through the firewall. What you’ll end up doing is to modifying policies which are applied to the firewall. How it works is that there’s always a single policy attached to the firewall, if you need to update the…
Installing OCI Network Firewall – Provisioning and Configuration
Now we’re going to follow the initial design I laid out here. We already have networking provisioned, so next step will be to use OCI Console and provision our OCI Network Firewall. Once we’ve provisioned it, I’ll see what happens with traffic when it hits the firewall. Final post of this series will be then…
Installing OCI Network Firewall – Design
One of the cool things Oracle has brought to OCI is managed network firewall service which is based on Palo Alto. Before OCI Network Firewall I saw constant requirement to provision self-managed firewall such as Palo Alto, Fortinet, Check Point etc. This is still a requirement as OCI Network Firewall might not provide all the…
Helping to troubleshoot with OCI VCN Flow Logs
I’m a huge fan of using tools available to help troubleshoot any issues there are. Luckily OCI has many free tools available such as Network Path Analyzer, which I’ve touched in the past. This time we’re going to look on VCN Flow Logs, I think as a starting point we should be looking on enabling…
