Hi,

I would like to know which is the best and recommended SQL query optimization/tuning tool for DB2 windows from below?

1. Optimization Service Center for DB2® for z/OS® (OSC), a convenient workstation tool for analyzing EXPLAIN output
2. OMEGAMON® DB2 Performance Expert, a tool which can help you with SQL performance
3. EXPLAIN, a DB2 monitoring tool
4. DB2 SQL Performance Analyzer, a tool that provides you with an extensive analysis of SQL queries without executing them.
5. Toad for DB2

And if any other good tool is also there, do let me know. Thanks.


Regards,
Gokul

Gokul,
Personally #3 (pure DB2 Explain) has always met my needs. I recommend trying it before paying money for another product.
