Overview/Description
Ensuring that a database is performing at its optimum capacity is crucial for any database administrator. Resolving performance problems using views and diagnostic and tuning tools when a database is not meeting its performance requirements is just as important. This course provides key RAC monitoring and tuning techniques using Enterprise Manager Cloud Control and built-in database tools like AWR, ASH, and ADDM. This course is one of a series in the SkillSoft learning path that cover a portion of the objectives for exam 1Z0-068 Oracle Database 12c: RAC and Grid Infrastructure.
Target Audience
Oracle Database Administrators, Systems Administrators, Technical Consultants.
