\section{SICS Invocation}

\label{f0}

SICS is a client server system. This means there are two programs. The first
is a
SICServer which does the actual instrument control work. A user rarely needs
to bother about this server program as it is meant to run all the time.
See instructions below if things go wrong. The user has only to deal with
the SICS client programs. These implement the user interface to SICS.
SICS Clients and the SICServer communicate with each other through TCP/IP
sockets.   

Currently four SICS clients are available:
\begin{itemize}
\item  A command line control client which allows to control the measurement.
\item  A status display for DMC.
\item  A status display for TOPSI.
\item  A status display for SANS.
\end{itemize}
These programs can be started on a DigitalUnix system by issuing the
following commands at the command prompt:
\begin{description}
\item[sics \&]  for the control client.
\item[powderstatus \&]  for the DMC status display client.
\item[topsistatus \&] for the TOPSI status display.
\item[sansstatus \&]  for the SANS status display.
\end{description}
On a PC you may find icons for starting the different prograsm on the
desktop.
Each of these clients has usage instructions online which can be displayed
through the help/about menu entry. 

\subsection{Connecting and Logging in}



After startup any SICS client is not connected to a SICS server and thus not
active. A connection is established through the connect menu of the client.

SICS is a multi user instrument control system. In order to  prevent
malicious manipulations of the instrument SICS supports a hierarchy of user
rights. In order to run an experiment you need at least user level privilege.
In order to achieve this privilege you have to invoke the User Parameter/Set
Rights dialog. There you have to enter the apropriate username and password
kindly provided by your instrument scientist.

\subsection{Restarting the Server}



The SICS server should be running all the time. It is only down if something
went wrong. You can check for the presence of the SICS  server by loging in
to the instrument computer and typing {\bf CheckSICS} at the command
prompt. The output will tell you what is happening. If you need to restart
the SICS server log in as the instrument user at the instrument computer and
invoke the apropriate command to start the server. These are:
\begin{description}
\item[DMC] Computer = lnsa05,User = DMC, Command = DMCServer
\item[TOPSI] Computer = lnsa03,User = TOPSI, Command = TOPSIServer
\item[SANS] Computer = lnsa07,User = SANS, Command = SANSServer
\end{description}
If all this does not help look under trouble shooting
SICS.

\section{SICS News Ticker}

\label{f2}

This page contains information about the latest bug fixes, releases and other
miscellaneous information about SICS. 


\subsection{Juli 1998}


\begin{description}
\item[Status OutOfMemory] Bug in status display clients fixed which caused OutOfMemory after 
some time of automatic update.
\item[topsistatus ] TOPSI has got a java status client now as well. Can be invoked with
 {\bf topsistatus}. On the WWW also.
\item[commandlog] On popular demand the SICS server can now write a log file which logs all
communication between clients with user or manager privilege and the SICserver. 
This log is off by default. There is a new SICS command 
commandlog which serves to configure this log. 
\item[8-fold counterboxes.] SICS now reads all eight monitors.
\item[sicsinstall] There is now a shell script which automatizes updating and installing SICS. For more
information see the setup section of the SICS managers guide.

\section{User Names and Passwords}
\begin{itemize}
\item All instruments have know an account {\bf lnsuser 98lns2} with user 
privilege.
\item Manager passwords are:
\begin{itemize}
\item TOPSI: Mugger Daniel
\item DMC: Manager Lucas
\item SANS: Manager Joachim
\end{itemize}
User names and passwords can be changed by editing the instrument
configuration file.
\end{itemize}

\section{SICS on the WWW}
\subsection{Client access}
Following decisions made  at a recent SICS user meeting, SICS clients are
made avaialable on the WWW. Access is restricted to the PSI domain. A
username and a password is needed in order to access the clients. This is
currently set to: sinquser 98sinq2. 
The URL's for the clients are:
\begin{description}
\item[Command Line Client]http://lns00.psi.ch/sics/client/sicsclient.html
\item[DMC Status]http://lns00.psi.ch/sics/client/powderstatus.html
\item[TOPSI Status]http://lns00.psi.ch/sics/client/topsistatus.html
\item[SANS Status]http://lns00.psi.ch/sics/client/sansstatus.html
\end{description}

\subsection{Documentation}

All SICS User documentation is accessible at:\\
http://lns00.psi.ch/sics/index.html \\
Postscript versions of the SICS user
documentation inhabit the doc directory of your instrument account.

The SICS manager documentation is also available on WWW. URL:\\
http://lns00.psi.ch/sics/manager/manager.htm \\Access
 to this directory is
restricted to the psi.ch domain. A username and password must be given in
order to be given access to these pages. These values are currently set to:
bigboss DJLmanager (can be remembered as: Daniel, Joachim, Lukas manager).

There is now a WWW document which informs about new SICS features, bug fixes
etc. This is available at:\\
 http://lns00.psi.ch/sics/manager/sicsnews.htm  \\
The same access restrictions as given for the manager documentation above
apply. 

Installation instructions for SICS clients on PC's can be found at:\\
http://lns00.psi.ch/sics/cliinst.htm\\
 Currently only real PC's are covered,
but instructions for Mac's will follow some day or another. Any volunteers?
