Diagnosis
The new SAPDBA option '-statistics' executes, in one run, alloperations required to update the cost-based optimizer statistics.Previously, this was executed in two steps.
1. Needs Analysis: SAPDBA option '-checkopt' , DB13 action 'CheckOpt'
2. Generate Statistics: SAPDBA option '-analyze' , DB13 action'AnalyzeTab'
In addition, the new option allows you to generate statistics inparallel, which considerably reduces runtimes. For this reason, you canno longer use the old actions in DB13 but instead must use the newaction 'UpdateStats'.

System Response
DB13 displays the old actions as 'Unknown'.

Procedure
Delete the 'Unknown' actions from the DBA Planning Calendar andschedule instead the new action 'UpdateStats'. This action is normallyscheduled to run once a week, such as each Sunday.
Caution: The old actions scheduled in the past are displayed as'Unknown' in the DBA Planning Calendar until you delete them from theCalendar.
