Hi Ludovico,
Thank you for this information.
>but at every new version DBCA was introducing a new surprise
The arbitrary behavior across different releases is a no-go. This information is invaluable, because I couldn’t have discovered it by testing dbca on a single release.
> What I would do if I have to start again is to have a first script that automates the creation of new templates from scratch (CREATE DATABASE {{tpl_name}} ...) and a second one that clones the template: copy of datafiles + create controlfile + dbid + add tempfiles, nothing complex at all. In this way you can also integrate the database creation with the management of your ACFS filesystem, if you want to leverage snapshots.
Interestingly, our current implementation with the create templates is identical to your idea, because we’ve been leveraging ZFS snapshots. The implementation has proven very robust and low-maintenance. We’ve been using it since 10 years without any significant modifications. We’ll reuse the same concept for ACFS.
> Ansible, python or shell (if done properly) are good solutions for that.
Python seems the best fit for our team. We’ll also check if Ansible would add value for some functionalities. Shell misses lots of features for complex processing (variable scoping, data structures, built-in libraries etc.). It would be expensive and less agile in the long run.
I’d be grateful if you could share your preferences with regard to the following points concerning ACFS:
Best regards,
Nenad
