SNODE in jcl means node from which you are sending a file
Node --- mainframe region name |

It is not listed in the manuals as a JCL parameter, so it seems to me that it could mean just about anything without knowing the context where it's being used.
Could you provide an example of it usage? Is it used in the JOB statement, on an EXEC statement, or in a DD statement? |

I have seen a SNODE in the NDM tool ( Connect:Direct) , which specifies the Secondary Node. Suppose if a file is transfered from NODEA to NODEB then NODEA is PNODE (Primary Node) and NODEB is SNODE (Secondary Node). |

Sarath,
Am damn sure about my concept.
Superk,
It is not used in JOB or EXEC stmt.SNODEs and PNODEs are used as control cards for NDM.
//step95 EXEC PROC=NDMWAIT,
// COND=(0,NE),
//*
//NDM01.SYSUT1 DD DSN=dsn1 for signing on, (SEND SIGNON)
// DISP=SHR
// DD DSN=dsn2, (PROC=COPYWAIT)
// DISP=SHR
// DD DSN=ds3 for receving info, (RECEIVE SNODEID)
// DISP=SHR
// DD DSN=dataset4, (CONSTANT DATA)
// DISP=SHR
//*
// DD * *** NDM CONTROL CARDS ***
SNODE=region name from where we are sending the file
&FROMNODE=PNODE
&TONODE=SNODE
&DSN1=
&DSN2=
&DISP1=NEW
&DISP2=CATLG,CATLG
&UNIT=DISK
SIGNOFF
/*
SNODE can be either in &FROMNODE or in &TONODE based on the need
(file transferring region from and to).
The above step is for SNODE denoting receiving region name.There are some other NDM procs such as NDMRNJOB are present.syntax slightly differs but concept and NODE details are same.
hope this helps. |

Hi R,
Your reply implied that SNODE was a part of JCL (a JCL concept, if you will). It is really a part of NDM.
Don't be upset because we were confused. |

Its not a JCL concept.Its a part of NDM proc and a must in it.
sorry to keep u messing up.
My reply implies that SNODE is a must in NDM used in JCL.
Anyhow thanks for asking me again.I didn't get upset,really |

radhakrishnan82,
There is much more to NDM than the movement of data from one node to other node, it can also be used as a scheduler of Jobs. Every process in NDM has a PNODE and SNODE.
That is why

cant be true always. PNODE is the Node where u submit the process and SNODE interacts with the PNODE. In certain cases PNODE and SNODE is the same. One more thing both PNODE and SNODE are optional. I am also attaching the USER GUIDE to verify. |
