We are looking to replace our current SAP systems with a new one. We were thinking of pointing using a friendly URL to point to the database such as prodcutionSQLDB.ACME.com and productionOracleDB.ACME.com instead of using DB Server name.
This way our application servers just get this FQDN to point to the database. THis would simplify our DR planning and future migrations.
The question is, does SAP require certificates or something similar where the application servers would not be able to communicate with the DB (SQL or Oracle). My understanding is SQL and Oracle use username\pass to authenticate, or does SAP rely on certificates to communicate with the DB servers?
