The video tutorial covers creating a database link to access the SOE schema in a remote database. It involves setting up virtual machines, creating a user in the Windows database, and establishing a database link. The tutorial also demonstrates accessing remote database objects and creating synonyms for easier reference. The session concludes with cleanup steps and a summary of the practice.

What is the first step in setting up a database link according to the practice?

• Creating a new user in the database

• Ensuring virtual machines are running

• Installing additional software

• Configuring the firewall settings

Which parameter value allows creating database links with any name?

• global_names = false

• db_link_names = true
