Resilience

Resilience

The PowerCenter Repository Service is resilient to temporary unavailability of PowerCenter Repository Service clients and the PowerCenter Repository database.
An application service can be unavailable because of network failure or because a service process fails. You can configure the resilience timeout for the connection between the PowerCenter Repository Service and the following components:
PowerCenter Repository Service Clients
A PowerCenter Repository Service client can be a PowerCenter Client or a PowerCenter service that depends on the PowerCenter Repository Service. For example, the PowerCenter Integration Service is a PowerCenter Repository Service client because it depends on the PowerCenter Repository Service for a connection to the repository.
The PowerCenter Repository Service resilience timeout period is based on the resilience properties that you configure for the PowerCenter Repository Service, PowerCenter Repository Service clients, and the domain.
The Web Services Hub is not resilient to the PowerCenter Repository Service.
PowerCenter Repository Database
The PowerCenter repository database might become unavailable because of network failure or because the repository database system becomes unavailable. If the repository database becomes unavailable, the PowerCenter Repository Service tries to reconnect to the repository database within the period specified by the database connection timeout configured in the PowerCenter Repository Service properties.
If the repository database system has high availability features, set the database connection timeout to allow the repository database system enough time to become available before the PowerCenter Repository Service tries to reconnect to it. Test the database system features that you plan to use to determine the optimum database connection timeout.
