如下设置可以保证在网络中断后tso仍然可以继续active，并等到下一次reconnect
sys1.tcpparms(tnprof7d) -- Dataset name and PDS name based on your system setting, do srchfor ALLOWAPPL in your tcp parm PDSE
ALLOWAPPL TSO* DISCONNECTABLE; <-- This will allow all TSO session keep active even network broken happen.
<—TSO* 很依赖于系统设置，有些session的acb 就不是tso开头，而是系统设定的名字，这时候要用d net,id=tso,e 来看具体的名字
SYS1.PARMLIB(TSOKEY00) -- Dataset name based on your system setting, change to TSOKEYxx per your system.
RECONLIM=180 <-- keep the session for 3 hour.
