I’m using hibernate which is 5.1.17 and having Oracle 12C DB with “org.hibernate.dialect.Oracle12cDialect”. Now am thinking to upgrade Oracle DB to Oracle 19C.

For Upgrading to 19c, whether “org.hibernate.dialect.Oracle12cDialect” will be supported along with hibernate-5.1.17 ?

Unless Oracle removed functionality in 19c that Hibernate relies on, which I doubt, then there should be no problem. You should consider upgrading Hibernate ORM as well though as 5.x versions are being “phased out”, so if you run into a problem with that version, you’re on your own.
