If the VGRAPPL parameter is specified in an EMAS complex, this parameter specifies a common VTAM generic resource name for the entire EMAS complex.
Specifying the common VTAM generic resource name in the session request can initiate VTAM cross memory sessions to any of the EMAS members.
When you are using the VTAM generic resource name, by default VTAM tries to request a session with an EMAS member in the same MVS image.
If it is not possible to get the session that was requested, VTAM uses normal load balancing when passing the session request to one of the active EMAS members.
The CA Roscoe/cross-memory online retrieval option runs as a command processor under ETSO/Roscoe.
Important! This interface requires cross-memory services to be installed. For more information about cross-memory services, see the Install Cross‑Memory Services section in this chapter. Be sure to set the parameter XMSSUB to YES in the JCL for the cross‑memory services task.
