  • 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
    Server pool name: Free
    Importance: 0, Min: 0, Max: -1
    Candidate server names:
    Server pool name: Generic
