QUẢN TRỊ CƠ SỞ DỮ LIỆU ORACLE, MÔN ADMIN WORKSHOP II

(Oracle Database 11g: Administration Workshop II Release 2)

 
MỤC TIÊU KHÓA HỌC
Khóa học giúp học viên hiểu được tầm quan trọng của việc sao lưu và phục hồi cơ sở dữ liệu như thế nào. Từ đó, học viên sẽ nắm bắt thuần thục các cách thực hiện sao lưu và phụ hồi trong Oracle cũng như biết cách làm thế nào để xác định và kiểm tra nó.
 
Sau khi hoàn tất khóa học, học viên sẽ đạt được các kiến thức sau:
  • Back and recover a database (and its parts) with RMAN (command-line and Enterprise Manager)
  • Use flashback technology to view past states of data and to revert either objects or the entire database back to a past state
  • Use an appropriate and flexible memory configuration for your database
  • Identify burdensome database sessions and poorly performing SQL
  • Configure the Oracle Database for optimal recovery
  • Configure the database instance such that resources are appropriately allocated among sessions and tasks
  • Schedule jobs to run inside or outside of the database
  • Use compression to optimize database storage and duplicate a database
