The Generic Server Pool

The Generic Server Pool

The Generic server pool stores pre-11g release 2 (11.2) Oracle Databases and administrator-managed databases that have fixed configurations. Additionally, the Generic server pool contains servers that match either of the following:

• Servers that you specified in the HOSTING_MEMBERS resource attribute of all resources of the application resource type

·         Servers with names you specified in the SERVER_NAMES attribute of the server pools that list the Generic server pool as a parent server pool

The Generic server pool's attributes are restricted, as follows:

·         No one can modify configuration attributes of the Generic server pool (all attributes are read-only)

·         When you specify a server name in the HOSTING_MEMBERS resource attribute, Oracle Clusterware only allows it if the server is:

o    Online and exists in the Generic server pool

o    Online and exists in the Free server pool, in which case Oracle Clusterware moves the server into the Generic server pool

o    Online and exists in any other server pool and the client is either a cluster administrator or is allowed to use the server pool's servers, in which case, the server is moved into the Generic server pool

o    Offline and the client is a cluster administrator

·         When you register a child server pool with the Generic server pool, Oracle Clusterware only allows it if the server names pass the same requirements as previously specified for the resources.

Servers are initially considered for assignment into the Generic server pool at cluster startup time or when a server is added to the cluster, and only after that to other server pools.
