-<P>CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
-at
-<A HREF="http://www.sourceforge.net">Sourceforge</A>. This means
-that it is possible to update your DXSpider installation to the latest
-sources by using a few simple commands.
-<P>
-<P>THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
-INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
-THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
-YOU HAVE BEEN WARNED!!!
-<P>
-<P>DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
-CONSEQUENCES!!!
-<P>
-<P>I am of course assuming that you have a machine with both DXSpider and
-Internet access running.
-<P>
-<P>BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
-ENTIRE SPIDER TREE!!
+<P>Spider allows the creation of local or remote databases. It supports
+chained databases, allowing several different databases to be scanned
+with one simple command. Importing of databases is limited at present
+to the standard AK1A databases such as OBLAST and the DB0SDX QSL
+database but will expand with time.
+<P>
+<H2><A NAME="ss10.1">10.1 Creating databases</A>
+</H2>
+
+<P>Creating a database could not be more simple. All the commands are
+sent from the cluster prompt as the <EM>sysop</EM> user.
+<P>To create a database you use the command <EM>dbcreate</EM>. It can
+be used in 3 different ways like so ..
<P>
-<P>Assuming you are connected to the Internet, you need to login to the
-CVS repository and then update your Spider source. There are several
-steps which are listed below ...
+<BLOCKQUOTE><CODE>
+<PRE>
+dbcreate <name>
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>To simply create a database locally, you just tell the command the
+name of the database. This does not create the actual database, it
+simply defines it to say that it exists.
<P>
-<P>First login as the user <EM>sysop</EM>. Next you need to connect to the CVS
-repository. You do this with the command below ...
+<BLOCKQUOTE><CODE>
+<PRE>
+dbcreate <name> chain <name> [<name>...]
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>This creates a chained database entry. The first database will be
+scanned, then the second, the third etc...
<P>
+<BLOCKQUOTE><CODE>
<PRE>
-cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
+dbcreate <name> remote <name>
</PRE>
-<P>You will get a password prompt. Simply hit return here and your machine should
-return to a normal linux prompt.
+</CODE></BLOCKQUOTE>
+<P>This creates a remote entry. the first name field is the database
+name at the remote node, then the remote switch, then the actual
+node_call of the remote node, for example...
<P>
-<P>What happens next depends on whether you have an existing installation that
-you want to update with the latest and greatest or whether you just want
-to see what is there and/or run it on a new machine for testing.
-Either way you will want to change directory to a new place, if you want to
-update an existing installation then I suggest /tmp, otherwise choose a
-suitable place according to the normal installation instructions.
+<BLOCKQUOTE><CODE>
+<PRE>
+dbcreate buckmaster remote gb7dxc
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>Remote databases cannot be chained, however, the last database in a
+chain can be a remote database.
<P>
-<P>The next step will create a brand new 'spider' directory in your current
-directory.
+<H2><A NAME="ss10.2">10.2 Importing databases</A>
+</H2>
+
+<P>The only databases that Spider can currently import are the standard
+AK1A databases such as OBLAST or the DB0SDX qsl and address database.
+This will be added to with time.
+<P>To import such a database, first put the file somewhere useful like /tmp
+and then issue the following command ...
<P>
+<BLOCKQUOTE><CODE>
<PRE>
-cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
+dbimport oblast /tmp/OBLAST.FUL
</PRE>
-<P>This command is all on one line.
+</CODE></BLOCKQUOTE>
+<P>This will update the existing local oblast database or create it if
+it does not exist.
<P>
-<P>Hopefully your screen should show you downloading files. The -z3 simply compresses
-the download to improve speed.
-When this has finished, you will have exactly the same as if you had untarred a full
-tarball PLUS some extra directories and files that CVS needs to do the magic that
-it does.
+<H2><A NAME="ss10.3">10.3 Checking available databases</A>
+</H2>
+
+<P>Once a database is created, you will want to check that it has been
+added. To do this use the <EM>dbavail</EM> command. This will
+output the available databases. For example ...
<P>
-<P>Now if you are doing a new installation, that's it. Carry on as if you have
-just downloaded and untarred the lastest tarball.
+<BLOCKQUOTE><CODE>

+</CODE></BLOCKQUOTE>
<P>
-<P>If you want to upgrade your current installation then do this ...
+<H2><A NAME="ss10.4">10.4 Looking up databases</A>
+</H2>
+
+<P>To look for information in a defined database, simply use the <EM>dbshow</EM>
+command, for example ...
<P>
<BLOCKQUOTE><CODE>
<PRE>
-tar cvfz /tmp/s.tgz spider
-cd /
-tar xvfzp /tmp/s.tgz
+dbshow buckmaster G0YLM
</PRE>
</CODE></BLOCKQUOTE>
-<P>This is assuming you downloaded to the /tmp directory of course.
-<P>
-<P>NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
-correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
-<P>Remember to recompile the C client (cd /spider/src; make)
+<P>will show the information for the callsign G0YLM from the buckmaster
+database if it exists. To make things more standard for the users
+you can add an entry in the Aliases file so that it looks like a standard
+<EM>show</EM> command like this ...
<P>
-<P>At this point the files have been upgraded. You can (usually) restrt the cluster
-in your own time. However, if you attempt to use any new commands or features
-expect it to be fatal! At least your cluster will have been restarted then so it
-will be too late to worry about it!
+<BLOCKQUOTE><CODE>
+<PRE>
+'^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>Now you can simply use show/buckmaster or an abreviation.
<P>
-<P>Now the magic part! From now on when you want to update, simply connect to the
-Internet and then, as the user <EM>sysop</EM> ...
+<H2><A NAME="ss10.5">10.5 Removing databases</A>
+</H2>
+
+<P>To delete an existing database you use the <EM>dbremove</EM> command.
+For example ...
<P>
<BLOCKQUOTE><CODE>
<PRE>
-cd /spider
-cvs -z3 update -d
+dbremove oblast
</PRE>
</CODE></BLOCKQUOTE>
-<P>and your files will be updated. As above, remember to recompile the "C" client
-if it has been updated (CVS will tell you) and restart if any of the perl scripts
-have been altered or added, again, CVS will tell you.
-<P>
-<P>You will find any changes documented in the /spider/Changes file.
+<P>would remove the oblast database and its associated datafile from the
+system. There are no warnings or recovery possible from this command.
+If you remove a database it ceases to exist and would have to be created
+from scratch if you still required it.
<P>
