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 that you want 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.
