There are times when we need to encapsulate certain traffic flows in an overlay network. Hopefully it's a rare need, as it adds additional header overhead, processing requirements and complexity to an environment. Drawbacks aside, the ability to create overlay networks is a valuable necessity sometimes and is a good tool to have in your tool belt! Generic Routing Encapsulation (GRE) is a common tunneling protocol, allowing for encapsulating both IP and non-IP protocols...

Overview We are currently seeing rapid adoption of Fusion Applications in the SaaS@Customer model. This and the strong Fusion Applications On-Premise installation base have been further secured by establishing strict rules for separation of Production Systems and Non-Productions Systems. Usually the mandate is to separate the network traffic on the logical level as well as the physical layer. Oracle VM technology offers a range of features to achieve different levels of...

Introduction This post will walkthrough the elements required, and purpose of each, to make a curl request to Oracle Cloud Infrastructure (OCI) REST services. While there are a variety of tools offered that make this task far easier than manually constructing a curl request, the purpose of this post is to provide an explanation of the required elements to make an OCI REST request and hopefully give a deeper understanding to those interested - especially if you ever want to...

Introduction In this article we shall discuss how to configure and run Secure Shell (SSH) Socks Proxy server needed for Oracle GoldenGate (OGG) replication between On-Premises and GoldenGate Cloud Service (GGCS) in the Oracle Public Cloud (OPC). The SSH Socks Proxy server is required in GoldenGate replication between On-Premises and OPC, only if there's no VPN connectivity between the two sites, and the only connection allowed to the replication target on the OPC is via SSH....

Introduction This document will walk you through how to configure Virtual Private Network as a Service (VPNaaS) with Oracle Data Integration Platform Cloud (DIPC) for connectivity between On-Premises Oracle database and Oracle Public Cloud (OPC). One major requirement for DIPC to be configured with VPNaaS is; DIPC must be provisioned to use IP Network instead of a Shared Network. Managing and configuration of OPC's IP Networks are not discussed in this article. It is assumed...

This blog provides steps to get Oracle API Gateway up and running on Oracle cloud- OCI Classic VM We will see following steps: 1. Create compute instance on Oracle Cloud Infrastructure Classic (OCI-classic) 2. Create Logical gateway in API management console and Assign grants to add nodes 3. Connect OCI-classic instance using SSH and copy setup files 4. Configure user, Entropy value on Linux OS 5. API Physical Gateway setup (gateway node setup) 6. Security rules changes in...

Purpose This article is meant to provide steps to test latency and throughput between servers and/or datacenters. The tests described here are not meant to test application performance from and end user perspective. Overview This post will provide an overview of some basic throughput and latency testing. Before testing, check your route. Is it static? Is it dedicated? If you using the open internet, results are going to be subject to more fluctuation. Something like...

Introduction In this article we shall discuss how to configure Oracle GoldenGate (OGG) replication between On-Premises and GoldenGate Cloud Service (GGCS) via HTTP Proxy Server. This discussion will include a sample configuration setup. This approach is very similar to configuring OGG Replication between On-Premises and GGCS via DMZ server, the only main difference is how the GoldenGate uses the mid-tier server. For details on configuring OGG Replication via DMZ server...

Introduction In Part 3 of 4 – SSSD Linux Authentication: Implementation Step-by-Step Guideline I covered all the necessary step-by-step details on deploying SSSD, but nothing ever seems to go perfect the first time does it. This is why I have included a final Part 4 that covers known problems I came across, though there could be more, and then troubleshooting tips I learned. These are all things I learned and want to share with you so that your SSSD implementation is...
