In computing, a Pool Registrar (PR) is a component of the reliable server pooling (RSerPool) framework which manages a handlespace. PRs are also denoted as ENRP server or Name Server (NS).
The responsibilities of a PR are the following:
- Register Pool Elements into a handlespace,
- Deregister Pool Elements from a handlespace,
- Monitor Pool Elements by keep-alive messages,
- Provide handle resolution (i.e. server selection) to Pool Users,
- Audit the consistency of a handlespace between multiple PRs,
- Synchronize a handlespace with another PR.
