Hello luciferHK, KVSS support The RecoverPoint KVSS utility is a command-line utility that enables applying bookmarks to Windows-based applications that support Microsoft Volume Shadow Copy Service (VSS). RecoverPoint supports all Microsoft-supported Windows, SQL Server, and Exchange Server releases. I am not seeing any option for Oracle. Please let us know if you have any other questions.
In RP4VM , using KVSS we create application consistency bookmark for  SQL DB. Do we have something similar for Oracle DB?? Any lead helpful.
