`Resource Group Dialog`:index:
******************************
Use the *Resource Group* dialog to create a resource group and set values for its resources. A resource group is a named, global group on which various resource usage limits can be defined. The resource group is accessible from all databases in the cluster. To use the *Resource Group* dialog, you must have superuser privileges. Please note that resource groups are supported when connected to EDB Postgres Advanced Server; for more information about using resource groups, please see the EDB Postgres Advanced Server Guide, available at:
http://www.enterprisedb.com/
Fields used to create a resource group are located on the *General* tab. The *SQL* tab displays the SQL code generated by your selections on the *Resource Group* dialog.

Use the fields on the *General* tab to specify resource group attributes:
* Use the *Name* field to add a descriptive name for the resource group. This name will be displayed in the tree control.
* Use the *CPU rate limit (%)* field to set the value of the CPU rate limit resource type assigned to the resource group. The valid range for a CPU rate limit is from 0 to 1.67772e+07. The default value is 0.
* Use the *Dirty rate limit (KB)* field to set the value of the dirty rate limit resource type assigned to the resource group. The valid range for a dirty rate limit is from 0 to 1.67772e+07. The default value is 0.
Click the *SQL* tab to continue.
Your entries in the *Resource Group* dialog generate a SQL command. Use the *SQL* tab for review; revisit the *General* tab to make any changes to the SQL command.
**Example**
The following is an example of the sql command generated by selections made in the *Resource Group* dialog:
.. image:: images/resource_group_sql.png
:alt: Resource Group dialog sql tab
The example creates a resource group named *acctg* that sets *cpu_rate_limit* to *2*, and *dirty_rate_limit* to *6144*.
