   <p>
    Installing Metacat requires a server running an SQL92 compliant database
    (Oracle 8i recommended) with at least 128MB RAM, and a Pentium III class
    processor or higher.  The amount of disk space required depends on the
    size of your RDBMS tablespace (which should be at least 10 MB,
    however Metacat itself requires only about 1 MB of free space after
    installation.  These instructions assume a Linux environment but may
    work on other UNIX type environments, however this has not been tested.
   </p>
   <p class = "header">Additional Required Software</p>
   <p>
    The server on which you wish to install Metacat must have the following
    software installed and running correctly before attempting to install
    Metacat.
    <ul>
      <li><a href="http://www.oracle.com">Oracle 8i</a> (or another SQL92

-            jones
+  tested with any of the 1.5.x versions yet, so probably best to stay with 1.4.x.
   Make sure that JAVA_HOME environment variable is properly set and that both
   java and javac are on your PATH.
   </p>
   <p class="header">Oracle 8i or Postgres</p>
   <p><i>Oracle:</i><br>
-            berkley
+   The Oracle RDBMS must be installed and running as a daemon on the system.
    In addition the JDBC listener must be enabled.  You can enable it by
    logging in as your Oracle user and typing the following:
    <pre>lsnrctl start</pre>
    Your instance should have a table space of at least 5 MB (10 MB or higher
    recommended).  You should also have a username specific to Metacat
    created and enabled.  This user must have most normal permissions
    including CREATE SESSION, CREATE TABLE, CREATE INDEX, CREATE TRIGGER,
    EXECUTE PROCEDURE, EXECUTE TYPE, etc.  If an action is unexplainably
    rejected by Metacat it is probably because the user permissions are not
    correctly set.

+  <p><i>Postgres:</i><br>
   Postgres can be easily installed on most linux distributions and on
   Windows (using cygwin) and Mac OS X.  Using Fedora Core or RedHat Linux,
   you can install the rpms for postgres and then run
   <code>/etc/init.d/postgresql start</code> in order to start the database.
   This initializes the data files.  You need to do a bit of configuration
   to create a database and set up a user account and allow internet access
   via jdbc.  See the postgres documentation for this, but here is a quick
   start:
   <ul>
      <li>Switch to the "postgres" user account and edit "data/pg_hba.conf", adding the following line to the file:<br>
      <code>host   metacat  metacat      127.0.0.1         255.255.255.255   password</code></li>
      <li>Edit the "data/postgres.conf" file and uncomment and edit the line
      starting with "tcpip_socket" so that it reads
      <code>tcpip_socket = true</code></li>
      <li>Run <code>createdb metacat</code> to create a new database</li>
      <li>Run <code>psql metacat</code> to log in using the postgres account and create a new "metacat" user account
      <ul>
         <li>In postgres, run <code>CREATE USER metacat WITH UNENCRYPTED PASSWORD 'apasswordyoulike';</code></li>
         <li>This creates a new account called metacat on the database named metacat</li>
         <li>Note: there are many ways to do this, so others such as using
         ENCRYPTED passwords will work fine.</li>
      </ul>
      </li>
      <li>Exit the postgres account back to root and restart the postgres
      database with <code>/etc/init.d/postgresql restart</code></li>
      <li>Test logging into the postgres db using the metacat account with
      the following command:
      <code>psql -U metacat -W -h localhost metacat</code></li>
   </ul>
   </p>
-            berkley
+  <p class="header">Ant</p>
   <p>
    Ant is a Java based build application similar to Make on UNIX systems.
    It takes in installation parameters from a file in the root installation
    directory named "build.xml".  The Metacat CVS module contains a default
    build.xml file that may require some modification upon installation.  Ant
-            jones
+   should be installed on the system and the "ant" executable shell script
-            jones
+   should be available in the users path. We note that the current build is
    not working with Ant 1.6.x, so you'll need to use an earler version.  We have
    successfully used Ant 1.5.1, 1.5.2, and some earlier versions.

    Once all of the prerequisite software is installed as described above,
    the installation of Metacat can begin.  First you must have a current
    version of the source distribution of Metacat.  You can get it two ways.
    Authorized users can check it out of the NCEAS

-            jones
+   system. You'll need both the "metacat" module and the "utilities" module to
    be checked out in sibling directories. The command is as follows:
    <pre>mkdir knb-software</pre>
    <pre>cd knb-software</pre>
    <pre>cvs checkout -P metacat</pre>
    <pre>cvs checkout -P utilities</pre>
    Or you can

   Metacat has a number of additional settable properties in file
   <code>metacat/lib/metacat.properties</code>. Under most circumstances,
   you will not need to modify this file because the properties of interest
   to you can be controlled by editing <code>build.properties</code> as
   described above. To learn more about Metacat's additional properties,

   <p>To run the scripts using ant, type <code>ant installdb</code>.  This does
   not work for postgres, so you'll need to run the xmltables-postgres.sql script
   manually (see next paragraph).
-            jones

   <p>To run the scripts manually, change to the

    SQLPlus.  Login as the oracle user that was set up for use with Metacat.

-            jones
+  </p>
   <p>Either way,
    you should see a bunch of output showing the creation of the Metacat table
-            berkley
+   space. The first time you run this script you will get several errors at the
    beginning saying that you cannot drop a table/index/trigger because it
    does not exist.  This is normal.  Any other errors besides this need to be
-            tao
+   resolved before continuing. The script file name for PostgreSQL is
-            costa
+   xmltables-postgres.sql and for Microsoft SQL server is

+   xmltables-sqlserver.sql.

    If the script has run correctly you should be able to type

+  <p class="header"><h2>Upgrading SQL Scripts</h2></p>
   <p>
     If you have an existing metacat installation, you should not run the install
     script because it will replace all of the older tables with new, empty
     copies of the tables.  Thus you would lose your data!  Instead, you can
     run some upgrade scripts that will change the table structure as needed for
     the new version.  If you are skipping versions, run each upgrade script
     for the intermediate versions as well.  Currently the upgrade scripts are:
    </p>
     <ul>
       <li>upgrade-db-to-1.2.sql</li>
       <li>upgrade-db-to-1.3.sql</li>
-            jones
+      <li>upgrade-db-to-1.4.sql</li>
-            jones
+    </ul>
    <p>
     So, if you had an existing metacat 1.0 installation and you were upgrading
-            costa
+    to 1.4, you would need to run all three scripts in sequence:
     upgrade-db-to-1.2.sql, upgrade-db-to-1.3.sql, and upgrade-db-to-1.4.sql.
     However, if you were starting from a Metacat 1.3.x
     installation, you would only need to run the upgrade-db-to-1.4.sql script.
