>90% of upgrade related problems are performance issues after an upgrade.

Source: Oracle Corp


Oracle tools for helping you tune the database:
  • Statspack - FREE - (See note 394937.1)





  • AWR - Diagnostics Pack & Tuning Pack license required.


  • Real Application Testing (Features: SQL Performance Analyser & Database Replay) - Tuning Pack license required.



Since 11g, Oracle recommend, instead of: storing outlines, fixing stats, using SQL hints, using the Rule Based Optimiser (desupported); you should use the SQL Plan Management tool along with SQL Profiling.

See spm_white_paper_ow07.pdf for more information.
