HI Tim,

What will happen if node is not pinned?
what is the purpose of POOL system in 11g RAC?

Pinning a node permanently associates the node name with the node number. If you don't pin them and an instance is down for a long time (past the lease period), the not number can be reused for a different node.

A pool in RAC is a specified group (pool) of server nodes. When you create a policy managed database it is assigned to a pool. RAC instances of that database can be run on one or more nodes within that pool. ... m#BABBDDGB
