Run-Time Policy Actions
CentraSite is installed with a set of actions that you use to define run-time policies for virtual services deployed on webMethods Mediator. These actions fall into the following four categories:
Security actions, which you use to identify and authenticate the consuming application that submitted a request, to enforce the use of the SSL protocol (if required), to perform encryption and decryption of specified parts of the request and response messages, and to validate signatures of messages that are digitally signed.
Logging actions, which you use to log the request and/or response messages associated with a virtual service. Logging actions can send the logged messages to Mediator's local log, CentraSite's policy or audit log, to an SNMP server and/or email the messages to specified addresses.
Performance monitoring actions, which you use to monitor specified metrics (for example, service availability, average response time, fault count, request count) and log instances when these metrics violate specified thresholds. Violations can be reported in Mediator's local log, in CentraSite's policy or audit log, in an SNMP server and/or sent as an email message to specified addresses.
Data validation actions, which you use to validate the request and/or response message against the WSDL associated with the virtual service.
Note: | CentraSite does not require you to deploy run-time policies with a virtual service. It is possible to deploy virtual services to webMethods Mediator without accompanying policies. In practice, however, this is rare. One nearly always deploys virtual services with, at the very least, some type of security-related policy to identify and authenticate the consuming application. |
