HyperSwap
HyperSwap对跨Sysplex的共享数据的影响
1.测试场景
1.1测试环境
硬件:
1台z990主机/2台DS8000/FICON连接
软件:
NetViewv5.1/SAv2.2/GDPSPPRCv3.2
1.2系统结构
PLEXP1
-包含BP0M/BP0D/BP0J系统,其中BP0M是GDPS/PPRC的K系统
-使用两台DS8000作为存储设备
-系统看到的地址在主盘是8800-8F20
-系统看到的地址在从盘是9800-9F1F,主盘到从盘形成PPRCDuplex关系
CSCPLEXT
-包含T101/T102系统
-使用的存储设备包括ESS800和PLEXP1共用主盘的DS8000
-系统看到ESS800上的盘地址范围是B000-B15F
-系统看到DS8000上的盘地址范围是8800-8F20,即PLEXP1系统的主盘
PLEXP1和CSCPLEXT这两个不同的Sysplex,具备跨Sysplex的数据共享能力.

1.4测试程序
1.4.1生成测试数据
PLEXP1系统运行如下Rexx产生用于测试数据的跨Sysplex共享数据:
BJSP02.REXX.EXEC（@2RWRTDS）
/************REXX***********/
TraceError

"execio1diskwindd2"
END
"execio1diskwindd1（finis"
"execio1diskwindd2（finis"
"freef（indd1）"
"freef（indd2）"
通过以下JCL提交Rexx来生成测试数据:

2.测试流程和结果分析
（1）在BP0D系统上提交作业BJSP02.REXX.EXEC（@2JWRTDS）产生测试数据
（2）在T101系统提交作业,读取共享数据:
TSCLJ.REXX.EXEC（@3JRDDS5）
TSCLJ.REXX.EXEC（@3JRDDS6）
（3）执行GDPS脚本DASD1_MAINT,进行HyperSwap操作.
