A store and forward transfer can be used to transfer a file indirectly when a destination system is not available. You can send a file to the mainframe where it is stored temporarily. When the destination system becomes available, the file is automatically forwarded from the mainframe to the destination system.
This method is also used when you have two devices that cannot communicate directly, such as an SNA‑only platform and a TCP/IP‑only platform. They must use the mainframe as an intermediate device. (UNIX and Windows systems are not intermediate devices.)
Example 1:
In the following example, the XCOM62 command is used. The file MYTEST.TST is sent to the intermediate z/OS node XCOMMVS2, which forwards the transfer to the remote PC system ENDEST and into the file named MYTEST.TST.
XCOM62 -c1 -f XIDEST=XCOMMVS2 REMOTE_SYSTEM=ENDEST LOCAL_FILE=MYTEST.TST REMOTE_FILE=MYTEST.TST
There must be a destination member created and enabled for the remote system in the z/OS Dynamic Control Library in order for CA XCOM Data Transport to forward the transfer successfully.
Note: The example above appears on more than one line here but is to be typed at the command prompt as a continuous command. Press Enter only after you have typed in all of your command information.
Example 2:
In the following example, the XCOMTCP command is used. The file MYTEST.TST is sent to the intermediate z/OS node XCOMMVS2, which forwards the transfer to the remote PC system ENDEST and into the file named MYTEST.TST.
XCOMTCP -c1 -f XIDEST=XCOMMVS2 REMOTE_SYSTEM=ENDEST LOCAL_FILE=MYTEST.TST REMOTE_FILE=MYTEST.TST
There must be a destination member created and enabled for the remote system in the z/OS Dynamic Control Library in order for CA XCOM Data Transport to forward the transfer successfully.
Note: The example above appears on more than one line here but is to be typed at the command prompt as a continuous command. Press Enter only after you have typed in all of your command information.
Use the following parameter with the REMOTE_SYSTEM parameter for store and forward transfers through an IBM mainframe system.
