Status of Control Room Logbook (CRL)
		------------------------------------

Background
----------
The CRL was originally developed by the HEPNRC group (based at FNAL)
as part of a DOE-wide electronic documentation project. At some point
the documentation project was dropped and FNAL CD picked up the CRL
part. It is currently in production use by D0 and is also being used
by MiniBooNE and BTeV. The web page is

http://www-cpd.fnal.gov/CRL/index.html 

The current version of the Logbook is 1.6. This has new
features such as full text search of entries. The release notes are
available http://www-cpd.fnal.gov/CRL/release_1_6/ReleaseNotes.html.

The documentation is currently being updated

Using the Logbook at Soudan
---------------------------
The Logbook was not really designed to be used remotely with the program
running on one machine and displaying on another. It is written in Java
and Java displays are known to be very slow over X-connections. The
developers are aware of this problem. The nature of MINOS means that
we very much want to be able to run the CRL in the mode where the
server is on one machine and the display is somewhere else. I have
discussed our needs with the developers and we have agreed that they
will work on a client-server implementation that would meet our
needs. They have agreed to have a version we can use by June 2002. 

I believe the product currently meets our needs as far a features
go. One should note that the product works over the network it is
just that the speed to draw the display is unacceptable.

I have purchased one regular mini-tower PC with flat panel monitor (to
minimize the amount of space it occupies on the desk in the control
room). It will be running RedHat 7.1 and will be on the Server LAN.

Question: We are currently using the notebook provided by Dave Demuth
to make entries at Soudan. We can continue using this until the client
server version of CRL is ready or we can switch to the CRL on the
machine above which can probably be at the mine and operational by the
end of March if I get my act together. The longer we use the notebook
the more entries we have to upload into CRL. The drawback would be
the CRL display performance if you were trying to run over the network.


Configuring the Logbook for MINOS
---------------------------------
I have been configuring pages that match the existing notebook pages.
I have duplicated some of what is currently there. It is possible to
put automatic entries into the logbook from other processes which I
have tested by have not implemented yet. I will use this to make
automatic run start/end entries from the information in the database
for example.

Web access
----------
A web server will be running on the logbook machine which will allow
collaborators to view what is happening at the detector. Annotations of
web page is supported providing you have a username/password for
CRL. For some examples of what web pages would look like take a look
at http://www-cpd.fnal.gov/CRL/users.htm for D0 and CMS. This page
also has some screen shots of what the logbook looks like. Other
screen shots can be found in the documentation.
