AWR Space Estimation
~~~~~~~~~~~~~~~~~~~~
| To estimate the size of the Automatic Workload Repository (AWR)
| in SYSAUX, we need the following values:
|
| – Interval Setting (minutes)
| – Retention Setting (days)
| – Number of Instances
| – Average Number of Active Sessions
| – Number of Datafiles
|
| For ‘Interval Setting’,
| Press <return> to use the current value: 60.0 minutes
| otherwise enter an alternative
|
Enter value for interval: 1
** Value for ‘Interval Setting’: 1
|
| For ‘Retention Setting’,
| Press <return> to use the current value: 8.00 days
| otherwise enter an alternative
|
Enter value for retention:
** Value for ‘Retention Setting’: 8
|
| For ‘Number of Instances’,
| Press <return> to use the current value: 1.00
| otherwise enter an alternative
|
Enter value for num_instances:
** Value for ‘Number of Instances’: 1
|
| For ‘Average Number of Active Sessions’,
| Press <return> to use the current value: 12.0
| otherwise enter an alternative
|
Enter value for active_sessions: 30
** Value for ‘Average Number of Active Sessions’: 30
| ***************************************************
| Estimated size of AWR: 6,026.5 MB
|
| The AWR estimate was computed using
| the following values:
|
| Interval – 1 minutes
| Retention – 8.00 days
| Num Instances – 1
| Active Sessions – 30.00
| Datafiles – 12

Optimizer Stat History Space Estimation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| To estimate the size of the Optimizer Statistics History
| we need the following values:
|
| – Number of Tables in the Database
| – Number of Partitions in the Database
| – Statistics Retention Period (days)
| – DML Activity in the Database (level)
|
| For ‘Number of Tables’,
| Press <return> to use the current value: 164.0
| otherwise enter an alternative <a positive integer>
|
Enter value for number_of_tables:
** Value for ‘Number of Tables’: 164
|
| For ‘Number of Partitions’,
| Press <return> to use the current value: 56.0
| otherwise enter an alternative <a positive integer>
|
Enter value for number_of_partitions:
** Value for ‘Number of Partitions’: 56
|
| For ‘Statistics Retention’,
| Press <return> to use the current value: 31.0 days
| otherwise enter an alternative <a positive integer>
|
Enter value for stats_retention:
** Value for ‘Statistics Retention’: 31
|
| For ‘DML Activity’,
| Press <return> to use the current value: 2 <medium>
| otherwise enter an alternative <1=low, 2=medium, 3=high>
|
Enter value for dml_activity:
** Value for ‘DML Activity’: 2

| Estimated size of Stats history 44.2 MB
|
| The space for Optimizer Statistics history was
| estimated using the following values:
|
| Tables – 164
| Indexes – 297
| Columns – 1,506
| Partitions – 56
| Indexes on Partitions – 196
| Columns in Partitions – 364
| Stats Retention in Days – 31
| Level of DML Activity – Medium
