Datacenter move and system check

I was working on a datacenter move project recently,

We had to create tons of servers needed to be created and infrastructure was to be moved from old outdated hardware to newer hardware at the new datacenter. I had the following procedure advised to the sysadmin team for preparing the servers.

• RDA was run with the HCVE option for middleware, database and EBS specifications.
• Corrections were accordingly implemented to nominated servers
• Templates were to be created from the corrected servers.
• All new servers were to be created from the templates that were created thus.

The images created hence were noticed to be a little different from the other one. These were SA configurable parameters. Thereby, I had to come up with a script that would check and identify miss-configurations that would come after the sysadmins. The sysadmins were then advised to run the script and hand over the server to the DBA team only after all errors were corrected.

Please find the script attached from my repository attached here -->
