keep your work after network broken

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.
