  • Using the alter system command from within a PDB
  • Instance parameter change impact

Managing Data with ILM:

  • What is automatic data optimization, heat map, and ADO?
  • DBA Heat map Segment view, monitoring statistics

  • The balanced search tree index structure for placing and locating files
  • Learn about data concurrency and data consistency in multi-user databases
  • The concepts of Locking and Deadlocks

Oracle Network Environment:

  • Study the client/server Network Environment, configuring the network
  • Connecting to the database
  • The Oracle Network Environment and database link
  • Starting up an instance, SHOUT DOWN, NOMOUNT, MOUNT, OPEN, PDB, OPEN, clone PDBS

Oracle Backup and Recovery
