  9. VARDECIMAL storage option • Only in Enterprise Edition (Developer/Evaluation) • Implemented at table level • Physical structural change in table and indexes. • Will lock the table exclusively for the duration of the change. • Run sp_db_vardecimal_storage_format to enable the database, and then sp_tableoption, to enable for the appropriate tables. • Cannot be used for system databases • http://msdn2.microsoft.com/en-us/library/bb326755.aspx

  10. Logon Triggers USE master; CREATE LOGIN login_test WITH PASSWORD = '3KHJ6dhx(0xVYsdf' GRANT VIEW SERVER STATE TO login_test; CREATE TRIGGER connection_limit_trigger ON ALL SERVER WITH EXECUTE AS 'login_test' FOR LOGON AS BEGIN IF ORIGINAL_LOGIN()= 'login_test' AND (SELECT COUNT(*) FROM sys.dm_exec_sessions WHERE is_user_process = 1 AND original_login_name = 'login_test') > 3 ROLLBACK; END; • http://msdn2.microsoft.com/en-us/library/bb326598.aspx

  12. Compatibility issues • Windows Vista • Office 2007 • SharePoint Services 3.0 • Oracle data sources that run on version 9.2.0.3 or later for reporting services • Hyperion System 9.3 BI+ Enterprise Analytics data source
