5.70 SHOWDVOL1 (Enable showing of DASD
volsers in device list)

5.70.1 Function

SHOWDVOL1 indicates whether to show the DASD VOL1 labels (volser) in the device list display. 'YES'
shows the volser in addition to the usual filename, whereas 'NO' shows the device list in a traditional file-
name only format. The 'ONLY' option shows only the volser; the filename is not shown at all. The default
is 'NO', which results in a traditional device list display. Note: This system parameter is only available if
Hercules is built with “OPTION_SHOWDVOL1”.

5.71 SHRDPORT (Shared device server port)

5.71.1 Function

SHRDPORT defines the port number (in decimal) on which the shared device server will listen. The
shared device server will allow other Hercules instances to access devices on this instance. Currently
only DASD devices may be shared. The default port is 3990. If you decide to use a different port number
then you must specify this port number on the device statements for the other Hercules instances. If no
SHRDPORT statement is present then the shared device server thread will not be activated.
