MDSplus Dispatcher and Servers

Installing a Dispatcher and Servers


This information is from running MDSplus on VMS, so no longer applies to NSTX.

One copy of MDSSERVER.EXE runs as the Dispatcher. Additional copies run as Servers, including at least one CAMAC server. In the original VMS-based system these tasks are installed as DECNET known network objects. Installing these tasks would normally be done at system boot.


$ NODENAME = f$getsyi("nodename")
$ if NODENAME.nes."MANGO" then exit
$
$ ncp := $ncp
$ oldpriv = f$setprv("SYSPRV,OPER")
$
$ ncp
  clear obj MANGO_CAMAC all
  set object MANGO_CAMAC number 129 file BE1:[NSTX.CAMAC]MC.COM
  define object MANGO_CAMAC number 129 file BE1:[NSTX.CAMAC]MC.COM


where MC.COM is

$ @mds$top:mdsplus
$
$ mdsserver :== $mdsserver
$
$ mdsserver mango_camac


MDS$TOP:MDSPLUS.COM supplies the MDSplus definitions and logical names; in particular, it adds MDS$ROOT to the definition of SYS$ROOT.

Determining what servers are installed


To verify that the server task is installed, use NCP:
MANGO$ mcr ncp
NCP>show known objects
