Small changes to indexing and SQL can dramatically cut CPU and improve response times on DB2 for z/OS.
DB2 performance often comes down to a handful of high-impact fixes.
- Review and rebuild fragmented indexes
- Eliminate unnecessary sorts
- Use EXPLAIN to catch table scans
- Tune bufferpools for your workload
- Keep RUNSTATS current
Our DB2 DBA program covers each of these hands-on.
