                                       ORACLE CLUSTER 的 node pin

     在cluster的打patch之前,要先unpin结点,以下是对于pin的解析;


In order to change the node pin behavior the appropriate command is the /crsctl pin/unpin css/
command, to pin or unpin any specific node. Pinning a node means that the association of a node
name with a node number is fixed. If a node is not pinned, its node number may change if the
lease expires while it is down. The lease of a pinned node never expires. Deleting a node with the
/crsctl delete node/ command implicitly unpins the node.

比如在一个正常的运行节点上

[root@rac2 ~]# olsnodes -s -l -a -t
rac2    Active  Hub     Unpinned
