Twelve Silver Bullets For Oracle Performance Tuning

"Contrary to the pontifications of theoreticians and ivory-tower academics, there are many silver bullets for Oracle performance tuning. By silver bullet, I mean a small set of commands that quickly relieves an acute performance bottleneck. Some of these techniques of just-in-time tuning have been codified in Oracle10g with the Automatic Memory Management (AMM) facility, in which the SGA regions are changed dynamically to meet changing demands in processing." writes Don Burleson for dbazine.com. So what are they? According to Don;

• Fix missing CBO statistics
• Replace an obsolete statistics gathering method
• Initialize missing Oracle instance parameters
• Add missing indexes
• Implement cursor_sharing=force
• Implement the KEEP pool for small-table full-scanned tables
• Change the CBO optimizer parameters
• Add additional SGA RAM
• Employ materialized views
• Create bitmap indexes
• Add freelists
• Windows Oracle issues
