This document outlines an upcoming hands-on workshop on upgrading to Oracle Database 19c. The agenda includes reviewing key upgrade principles and processes, performing hands-on labs upgrading databases from 12.1 and 18c to 19c, and an overview of related database technologies. The labs will guide attendees through installing Oracle 19c software and using the AutoUpgrade tool to upgrade a 12.1 container database to 19c, migrate a 12.2 non-CDB to a 19c pluggable database, and upgrade an 18c pluggable database to 19c through unplug/plug operations.

9. Choices| Our Recommendation
Production January April July October January
19.1.0 19.2.0 19.3.0 19.4.0 19.5.0 19.6.0
19.2.1 19.3.1 19.4.1 19.5.1
19.2.2 19.3.2 19.4.2
• Oracle recommends that customers stay current with Release Updates
– Minimize the chance of encountering known bugs and security vulnerabilities
– Reduce the likelihood of requiring separate interim one-off patches or merge patches
• Customers in a stable state may choose to be conservative and adopt revisions
– Security and regression fixes will be current
– Functional and performance fixes will lag behind updates by 3 or 6 months
– Higher chance of hitting known issues that are already fixed in a more recent update

22. Fallback Strategy | COMPATIBLE
• Recommendation:
• Update COMPATIBLE 7-10 days after upgrade
• Why wait?
• Allows fallback options: downgrade, flashback
• Why change?
• Enable new features (e.g. online datafile move, sharding etc)
• Minimum COMPATIBLE for 19c is 11.2.0
• COMPATIBLE is independent of OPTIMIZER_FEATURES_ENABLE
• How?
• alter system set compatible=‘19.0.0' scope=spfile;
