At the beginning of March, Oracle released the OCI “edition” of an Application Performance Monitoring Service (APM). The service is even available free of charge for smaller applications (up to 1,000 Events per hour). In the context of an Oracle E-Business Suite upgrade project and testing associated with this upgrade, I decided to take a closer look at the service.

I recently set up a new “E-Business Suite on OCI” environment for a customer. During the initial setup, the customer was not able to set up a Site-2-Site Tunnel between their on premise Data Center and the Oracle Cloud Infrastructure Data Center in Frankfurt. To make my initial setup and testing more convenient, I decided to set up a separate VPN tunnel to my own development network. This was easily done with a Rasperry Pi, as described in a previous blog post. Since my Home Router AVM Fritz!Box (7490 in my case) is able to establish an IPSEC VPN tunnel as well. I wanted to try this device out tool, so let's see how this worked.

The following blog post shows the (surprisingly simple) basic setup.

A customer recently told me they would like to get away from having to print, envelope and post mark thousands of invoices manually every month. Even though we have changed their invoicing process to an electronic one for most of their customers years ago by sending out emails through Oracle SOA Suite, they still had a considerable amount of customers insisting on printed invoices delivered by post.

Last week, Oracle released the latest version of E-Business Suite’s Cloud Manager tool. There is a blog post (https://blogs.oracle.com/ebsandoraclecloud/get-ebs-cloud-manager-2021) outlining the new features. I took a quick look at the features and upgraded two Cloud Manager instances to the latest release.

While moving a customer from On-Premises to Oracle Cloud Infrastructure, we recently conducted some performance testing before the final cutover. For the E-Business Suite database server, a physical box with 16 CPU cores was migrated to a VMStandard E3.Flex VM with 12 OCPU. From a CPU performance perspective, the new VM was much faster than the old box. Unfortunately, this was not the case on the I/O performance side.

In the first part of this 3 episodes blog series we'll cover what to expect and how to measure performance.

Last week when reading through the latest Oracle Cloud Infrastructure Release Notes I ran into a new Feature named "Private DNS". Since DNS has always been a pain when we were setting up E-Business Suite (EBS) instances on Oracle Cloud Infrastructure using Cloud Manager I gave it a closer look. And indeed, this is a great feature making life a lot easier in some situations.

This blog will have a look at typical customer situations and how we brought them onto a new SOA integration platform on OCI from a high level perspective.
