Migrating Oracle Database to Oracle Memory Speed
Starting with Oracle Database 19c Release Update (19.12) you can migrate your database files to Oracle Memory Speed (OMS) storage using SQL and RMAN commands.
Before you start the migration of the database files, create an OMS file system, mount it, and enable OMS on the database instance.

To achieve best redo performance, Oracle recommends that you add all members of a redo group to storage with similar characteristics. For Oracle Memory Speed (OMS) file system, adding all the members of the redo group to OMS provides efficient redo log write times. - Moving Data Files to OMS
