Recovery

Recovery

After a PowerCenter Repository Service restarts or fails over, it restores the state of operation from the repository and recovers operations from the point of interruption.
The PowerCenter Repository Service maintains the state of operation in the repository. The state of operations includes information about repository locks, requests in progress, and connected clients.
The PowerCenter Repository Service performs the following tasks to recover operations:
  • Gets locks on repository objects, such as mappings and sessions
  • Reconnects to clients, such as the PowerCenter Designer and the PowerCenter Integration Service
  • Completes requests in progress, such as saving a mapping
  • Sends outstanding notifications about metadata changes, such as workflow schedule changes
