Can DevTest support Oracle 18C (184.108.40.206)?
All supported DevTest releases.
Refer to section "Database Requirements" in the documentation of the DevTest release you are running.
Unless a specific release is mentioned in the documentation, then all releases within a version is supported.
NOTE: DevTest officially supports Oracle 12C Release 2 ( which is 220.127.116.11) but it should work fine with 18.104.22.168 but it is not certified.
Oracle 18C and 12C version information:
Oracle Database 18c is the first version of the product to follow a yearly release pattern. From here onwards the Oracle Database will be released every year along with quarterly updates. You can find more details on this change by visiting Oracle Support and taking a look at the support Document 2285040.1 or on Mike
Dietrich’s blog. If you’re confused as to why we’ve apparently skipped 6 releases of Oracle it may be simpler to regard “Oracle Database 18c” as “Oracle Database 12c Release 2 22.214.171.124”, where we’ve simply changed the naming to reflect the year in which the product is released.
