Service policy rules
Service policy rules define which service policy goal should be used to service a single piece of incoming work (request through the on demand router (ODR). This is done by associating a transaction class with a Boolean expression. Each transaction class is associated with exactly one service policy goal. The Boolean expression can be customized to match any specific piece of work (request through the ODR).
Before you begin
Define a service policy to categorize and prioritize work requests. See Defining a service policy for more information.
About this task
Optionally, you can add rules to your service policy. If the expression evaluates to true for a particular request, the policy associated with that rule is used. A work class contains a set of rules that is used by WebSphere® Virtual Enterprise and is used to classify requests, such as an HTTP request or IIOP call. Complete the following steps to define a service policy rule. This is just one example of how to create service policy rules.
Procedure
- Select Applications > Enterprise Applications > application_name > Service Policies. Click OK.
- From the Service policies tab, expand the work request type and the work class for which you want to create a rule, and click Add Rule> Rule Builder > Add
- Select the type of rule, such as Group ID This displays the rule builder panel. Continue to build a rule, specify the transaction class, or click OK
- Click the new rule to set its operators A predefined set of operators displays for the type of rule condition that is selected.
- Select the operator to use and enter the appropriate information in the provided field. For example, you can classify incoming requests for the StockTradeWork work class by a group ID to use a different transaction class.
- Select the (=) operator and type HTTP in the provided field, to provide a different transaction class for HTTP requests.
