I wanted to put this on the blog for quite a while but forgot to do so. Since Oracle Database 19c, Oracle Fail Safe has been deprecated. What does this mean?
Deprecation of Oracle Fail Safe
First of all, deprecated does not mean desupported. Oracle Fail Safe is still fully supported. But since Oracle 19c, you will find this note in the Windows Admin Guide:
Oracle Fail Safe is deprecated as of Oracle Database 19c. It can be desupported and unavailable in a future release.
Oracle recommends that you evaluate other single-node failover options, such as Oracle RAC One Node
If you wonder about the release notes saying, Fail Safe 4.2.1 is support with Oracle Database 12.2, then this refers to 220.127.116.11, 18c and 19c. And on MyOracle Support you will find the certification information for the different Windows releases:
Result will be:
