Oracle HA 之 Server Pool 实战

--创建server pool的两种方式：
    图形界面：console和dbca       演示-略
    命令行工具：srvctl和crsctl

--srvctl和crsctl创建serverpool

[grid@node2 ~]$ srvctl add serverpool -g s_pool -l 1 -u 2 -i 1 -n node1,node2
[grid@node2 ~]$ crsctl add serverpool c_pool -attr "MIN_SIZE=1,MAX_SIZE=2,IMPORTANCE=1"

--查看server pool

[grid@node2 ~]$ srvctl config srvpool
