Locking - Lock Statistics

Purpose

Use this view to find sessions (connections) that have been involved in locking problems:

  • Sessions that have recently experienced excessive lock waits, time outs, escalations or deadlocks
  • Sessions that have consumed excessive log space over their lifetime
  • Sessions that are currently holding many locks
  • Idle sessions

For context, this view also shows some basic information to help you identify the session without needing to jump to another view:

  • Application Name
  • User ID
  • Workload Name
