Changes to default functionality in 11g database

Many default functionalities of Oracle RDBMS have changed in 11g.  Here's a list:

• Conventional export is no longer supported
  
• Alert / trace file locations are different 
  
• New passwords are case sensitive by default
  
• The exact value of internal SGA overhead, or Startup overhead in Shared Pool, is listed in the new v$sgainfo view
  
• job_queue_processes parameter is non-basic in 11g
• Transparent Data Encryption at Tablespace Level (Metalink note 432776.1)
  
• Case sensitive passwords and strong user authentication (Metalink Note 429465.1)

Will update this list, as and when I come to know about the changes.
