Configuration Parameters › Destination Parameters for Single LUs, Groups of LUs, and Single IPNAMEs › GROUP

GROUP

This parameter can specify either of the following:

• One or more groups of LUs
• An alias for a single IP address

xxxxxxxx

Specifies one of the following:

• The name of a group of LUs. The name can contain up to eight alphanumeric characters.
• An IP address or IP name

Default: None

Notes:

• The GROUP parameter allows the multi‑threading of file transfers to nodes that support multiple logical units but not parallel sessions.
• When a transfer to a group is requested, CA XCOM Data Transport attempts to initiate a session with each LU in the group until it succeeds in establishing a session with one of them. CA XCOM Data Transport will then use that LU as the partner node to send the file to the remote system.
• You can specify GROUP instead of an LU parameter in the SYSIN01 or TSO/ISPF panel when scheduling a transfer to a group of one or more LUs.
• If you specify GROUP, the GROUP name must match the name of a CA XCOM Data Transport control library member.

Example 1

The following is an example of how to use the GROUP parameter to set up an alias for an IP name or IP address.

• In the DEST member:

  IPNAME=ipaddress (or ipname)
  GROUP=HOST1
  

• In the JCL:

  GROUP=HOST1
  

Example 2

The following is an example of how to use the GROUP parameter with a group of LUs.

• In the DEST member:

  LU=LU1,LU2,LU3 
  GROUP=NJLUS
  

• In the JCL:

  GROUP=NJLUS
