Local
area network (LAN) communications between OpenVMS Galaxy instances
are supported by the Ethernet LAN shared memory driver. This LAN
driver communicates to other instances in the same OpenVMS Galaxy
system through shared memory. Communicating with other instances
through shared memory provides performance benefits over traditional
LANs.
To load the LAN shared memory driver SYS$EBDRIVER, enter the
following command:
For OpenVMS Version 7.3-1 and later, in order for
LAN protocols to automatically start over this LAN device (EBAn,
where n is the unit number), the procedure
for loading this driver should be added to the configuration procedure:
SYS$MANAGER:SYCONFIG.COM.
The LAN driver emulates an Ethernet LAN with frame formats
the same as Ethernet/IEEE 802.3 but with maximum frame size increased
from 1518 to 7360 bytes. The LAN driver presents a standard OpenVMS
QIO and VCI interface to applications. All existing QIO and VCI
LAN applications should work unchanged.
In a future release, the SYS$EBDRIVER device driver will be
loaded automatically.
