In my previous post, I mentioned that I have created my Oracle Cloud Free Tier account and provisioned an Autonomous Database (ADB). Now, I'm ready to move my existing Oracle Application Express (APEX) to this new environment. Next, I'll describe the steps I took to move (1) workspace, (2) application and (3) data, from the old to new database.
As mentioned in a previous post, the Free Tier for Oracle Cloud (OCI) is every Oracle Developer's dream. For a while now, I have hosted a personal Oracle Application Express (APEX) instance on Linode. It currently runs an older Oracle Database 11gR2 Express Edition (XE), and I would like to upgrade it to version 18c. The key issue I had though, was that the existing virtual machine hosted on Linode, only has one gigabyte of RAM and that does not meet the 18c XE minimum requirement of two. That left me procrastinating for a long time, but perhaps a blessing in disguise. With this new offering, the next steps are pretty obvious.
Too good to be true? No, it's true!!!
After hearing the rumours for a few years now, Mr Larry Ellison finally announced the availablility of a Free Tier for the Oracle Cloud. The gift bundle includes two small compute instances and two Autonomous Databases. These offerings are a tiny fraction of what the Oracle Cloud provides, but are sufficient for Oracle Developers to maintain their own 24x7 development environments and possibly even production applications for small businesses and non-profit organisations.
Like everyone else in the Oracle Application Express (APEX) community, I wasted no time in getting my account provisioned and am currently working towards moving workspaces and applications from my old personal APEX instance, hosted on Linode.
With only three days remaining for my 30-day trial, I will finally close these series by discussing my experiences dealing with various levels of support from Oracle. Having used the Oracle Cloud (OCI) both in my day job and as a technology evangelist, I have had the opportunity to engage Oracle support at various levels: sales, customer and technical.
Oracle Function was announced late last year (2018), with limited availability to select Oracle Cloud customers. The platform is built on Fn and is Oracle's solution for developers wanting to deploy services using a Serverless Framework.
As succinctly explained by Kaslin Fields, a Fn function is a small embodiment of code that listens and speaks to HTTP streams. Ideally, each Fn function serves one, and only one purpose. It can be implemented in wide variety of programming languages and they are listed here (see the list of runtime options available).
