Use this dialog to specify the ASM performance required against the amount of tablespace available for ASM. For example, to maximize ASM performance using the minimum of tablespace. You can also analyze the performance gain achieved by increasing the amount of tablespace.
For more information, see:
Use this graph to evaluate the performance gain achieved by using the specified amount of allocated tablespace. As you change the amount of tablespace, you can see the performance impact displayed as a factor value.
Use this drop down list to specify which tablespace you want to use to store the summary tables.
Use this field when you know how much tablespace is available and you want to evaluate the performance for the value.
This figure is a factor value that represents the number of times faster that queries will run if ASM creates the recommended summaries.
Use this button to display the "Summary Wizard (ASM): Recommended Summaries dialog", where you specify which summaries will be created/removed for optimum performance gain given the space currently allocated.
Use this button to display the "Summary Wizard (ASM): Change default settings: List of dialog tabs", where you define the ASM policy.
When choosing a tablespace, it is recommended that you place summaries in a separate tablespace specifically intended for summary data. If such a tablespace does not exist, we strongly recommend you do not use the SYSTEM or TEMP tablespaces.
