Oracle PSUs include worm fixes and different vital safety updates. Starting with Oracle Database model 12.2.0.1, Amazon RDS for Oracle helps Liberate Updates (RU) rather than the PSU. To be told extra concerning the Oracle PSUs supported on Amazon RDS for each and every engine variations, see the Amazon RDS for Oracle Liberate notes. If the car minor model improve (AmVU) possibility is enabled, the DB example is upgraded to the most recent quarterly PSU or RU six to 8 weeks after it’s made to be had via Amazon RDS for Oracle for your AWS area. Those upgrades will occur all the way through the upkeep window. To be told extra, see the Amazon RDS upkeep window documentation.
