New Oracle10g ASH Query Examples
May 20, 2004

Author Robin Schumacher has just published great examples of the use of the Oracle10g Active Session History ASH views and how they are use in Oracle tuning:
Schumacher is the author of the bestselling Oracle Performance Troubleshooting by Rampant TechPress.

"Oracle has provided broad wait "classes" in Oracle 10g at the system and session level that help you identify wait activity in less-cryptic terms than has been the case in the past. These new categories (or classes) are:

  • Administrative
  • Application
  • Cluster
  • Commit
  • Concurrency
  • Configuration
  • Idle
  • Network
  • Other
  • Scheduler
  • System I/O
  • User I/O"
