Now is the time to move forward with an upgrade to your Grid Infrastructure to Oracle 19c!
Recently, I was working with a customer running an old, clunky Grid Infrastructure. They were faced with the always looming end of support, the painful mysterious issues that pop in and out. The ones that cause application failures and trouble with end users/applications. In addition, they weren’t positive they had built out the clusters correctly.
It’s a good thing they called us! Datavail is an expert at evaluating your current environment. We have a series of health checks, scripts, evaluation tools and years of experience to get you where you need to be.
By using our tools and test-driving Oracle’s new AHF (Autonomous Health Framework) I was able to use snoop in, clean up OS issues, apply missing packages, correct settings, install cleanup and maintenance scripts…and upgrade them to the latest version of Grid…19c!
Here’s a quick overview of my process:
1) Evaluate current environment
2) Correct issues and problems
3) Validate upgrade readiness
4) Install and patch latest Grid software to hosts
5) Rerun checks and balances
6) Coordinate maintenance window
7) Run upgrade
8) Smile with the customer 🙂
I completed the upgrade in a rolling fashion and two of three nodes were always online. Each node completed in approximately 20 minutes with the final node running a tad bit longer. We completed all upgrade activities and Application checkouts well before our allocated three-hour window expired.
The customer was so happy with Datavail’s performance that we’re starting the process of moving their databases to the latest and greatest! Contact us to learn more about how we can help get your databases upgraded to Oracle 19c.
