  <p>
62
   Installing Metacat requires a server running an SQL92 compliant database
63
   (Oracle 8i or Postgresql recommended) with at least 128MB RAM, and a Pentium III class
64
   processor or higher.  The amount of disk space required depends on the
65
   size of your RDBMS tablespace (which should be at least 10 MB, 
66
   however Metacat itself requires only about 1 MB of free space after 
67
   installation).  These instructions assume a Linux environment but may
68
   work on other UNIX type environments, however this has not been tested.
69
  </p>
70
  <p class = "header">Additional Required Software</p>
71
  <p>
72
   The server on which you wish to install Metacat must have the following
73
   software installed and running correctly before attempting to install
74
   Metacat.
75
   <ul>
76
     <li><a href="http://www.oracle.com">Oracle 8i</a> (or another SQL92
77
         compliant RDBMS like Postgres)</li>

<td>
96
  <p class="header">Java</p>
97
  <p>You'll need a recent Java SDK; J2SE 1.4.2 or later is required.  The latest metacat release
98
  has been tested most extensively with <a href="http://java.sun.com/j2se/1.5.0/">J2SE 5.0</a>
99
  and this is the recommended version.
100
  Make sure that JAVA_HOME environment variable is properly set and that both
101
  java and javac are on your PATH.
102
  </p>
103
  <p class="header">Oracle 8i or Postgres</p>
104
  <p><i>Oracle:</i><br>
105
   The Oracle RDBMS must be installed and running as a daemon on the system.
106
   In addition the JDBC listener must be enabled.  You can enable it by
107
   logging in as your Oracle user and typing the following:
108
   <pre>lsnrctl start</pre>
109
   Your instance should have a table space of at least 5 MB (10 MB or higher 
110
   recommended).  You should also have a username specific to Metacat
111
   created and enabled.  This user must have most normal permissions 
112
   including CREATE SESSION, CREATE TABLE, CREATE INDEX, CREATE TRIGGER, 
113
   EXECUTE PROCEDURE, EXECUTE TYPE, etc.  If an action is unexplainably 
114
   rejected by Metacat it is probably because the user permissions are not
115
   correctly set.
116
  </p>
117
  <p><i>Postgres:</i><br>
118
  Postgres can be easily installed on most linux distributions and on
119
  Windows (using cygwin) and Mac OS X.  Using Fedora Core or RedHat Linux,
120
  you can install the rpms for postgres and then run 
121
  <code>/etc/init.d/postgresql start</code> in order to start the database. 
122
  On Ubuntu and other Debian-based Linux distributions, you can use the apt-get command
123
  to install postgres: <code>sudo apt-get install postgresql-8.0</code> and 
124
  then run <code>/etc/init.d/postgresql-8.0 start</code> to start.
125
  
126
  This initializes the data files.  You need to do a bit of configuration
127
  to create a database and set up a user account and allow internet access
128
  via jdbc.  See the postgres documentation for this, but here is a quick 
129
  start:
130
  <ul>
131
     <li>Switch to the "postgres" user account and edit "data/pg_hba.conf", adding the following line to the file:<br>
132
     <code>host   metacat  metacat      127.0.0.1         255.255.255.255   password</code><br>
133
     If your host uses IPv6 addresses, you made need this line instead:
134
     <code>host   metacat  metacat      ::1               ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff password</code></li>
135
     <li>If you are using Postgresql pre-8.0, you must edit the "data/postgres.conf" file and uncomment and edit the line
136
     starting with "tcpip_socket" so that it reads 
137
     <code>tcpip_socket = true</code></li>
138
     <li>Run <code>createdb metacat</code> to create a new database</li>
139
     <li>Run <code>psql metacat</code> to log in using the postgres account and create a new "metacat" user account
140
     <ul>
141
        <li>In postgres, run <code>CREATE USER metacat WITH UNENCRYPTED PASSWORD 'apasswordyoulike';</code></li>
142
        <li>This creates a new account called metacat on the database named metacat</li>
143
        <li>Note: there are many ways to do this, so others such as using 
144
        ENCRYPTED passwords will work fine.</li>
145
     </ul>
146
     </li>
147
     <li>Exit the postgres account back to root and restart the postgres 
148
     database with <code>/etc/init.d/postgresql restart</code></li>
149
     <li>Test logging into the postgres db using the metacat account with 
150
     the following command: 
151
     <code>psql -U metacat -W -h localhost metacat</code></li>
152
  </ul>
153
  </p>
154
  <p class="header">Ant</p>
155
  <p>
156
   Ant is a Java based build application similar to Make on UNIX systems.  
157
   It takes in installation parameters from a file in the root installation
158
   directory named "build.xml".  The Metacat CVS module contains a default
159
   build.xml file that may require some modification upon installation.  Ant
160
   should be installed on the system and the "ant" executable shell script 
161
   should be available in the users path. The latest metacat release was tested with 
162
   Ant 1.6.5. <!-- We note that the current build is 
163
   not working with Ant 1.6.x, so you'll need to use an earler version.  We have 
164
   successfully used Ant 1.5.1, 1.5.2, and some earlier versions. -->
165
  </p>
166
  <p class="header">Tomcat</p>
167
  <p>
168
    Install Tomcat into the directory of your choice. The directory in which 
169
    you install Tomcat itself will be referred to as the "$CATALINA_HOME".
170
    We recommend that you install Tomcat version 5.5.  More details about 
171
    Tomcat installation are available <a href=" http://jakarta.apache.org/tomcat/index.html">here</a>.

182
   Once all of the prerequisite software is installed as described above, 
183
   the installation of Metacat can begin.  First you must have a current
184
   version of the source distribution of Metacat.  You can get it two ways.
185
   Authorized users can check it out of the NCEAS 
186
   <a href="http://www.nceas.ucsb.edu/cgi-bin/cvsweb.cgi/xmltodb/">CVS</a>
187
   system. You'll need both the "metacat" module and the "utilities" module to
188
   be checked out in sibling directories. The command is as follows: 
189
   <pre>mkdir knb-software</pre>
190
   <pre>cd knb-software</pre>
191
   <pre>cvs checkout -P metacat</pre>
192
   <pre>cvs checkout -P utilities</pre>  
193
   Or you can 
194
   <a href="@server@/software/download.html">download</a> a gzipped tar file
195
   from this site.
196
  </p>
197
  <p>
198
  
199
  <h2>Edit <code>build.properties</code> File</h2></p>
200
  <p>
201
   Once you have either checked out or unzipped and untarred the source
202
   distribution, you can begin the installation process.  Change into the 
203
   metacat directory and edit the file called "<code>build.properties</code>".  You will need 
204
   to change a number of configuration properties to match the setup on
205
   your system.
206
  </p>
207
  <p>
208
  The properties that you will likely need to change will include:
209
  <ul>
210
  <li><code>tomcat</code></li>
211
  <li><code>deploy.dir</code></li>
212
  <li><code>tomcatversion</code></li>

  <li><code>metacat.context</code></li>

  <li><code>config.hostname</code></li>

  <p><b>WARNING: Do NOT run this on an existing metacat installation as it

613

    
614
  <p>To run the scripts using ant, type <code>ant installdb</code>.  This does 
615
  not work for postgres, so you'll need to run the xmltables-postgres.sql script 
616
  manually (see next paragraph).
617
  </p>
618
  <p>To run the scripts manually, change to the
619
   metacat/build/src directory.  Then run you RDBMS's SQL utility.  In Oracle it is
620
   SQLPlus.  This tutorial assumes an Oracle database so this example is for
621
   SQLPlus.  Login as the oracle user that was set up for use with Metacat.
622
   At the SQLPlus prompt type the following: <pre><b>@xmltables.sql;</b></pre>
623
   For postgres, use a command like: 
624
   <code>psql -U metacat -W -h localhost -f build/src/xmltables-postgres.sql metacat</code>
625
  </p>
626
  <p>Either way, 
627
   you should see a bunch of output showing the creation of the Metacat table
628
   space. The first time you run this script you will get several errors at the 
629
   beginning saying that you cannot drop a table/index/trigger because it 
630
   does not exist.  This is normal.  Any other errors besides this need to be
631
   resolved before continuing. The script file name for PostgreSQL is 
632
   xmltables-postgres.sql and for Microsoft SQL server is 
633
   xmltables-sqlserver.sql.
634
  </p>
635
  <p>
636
   If the script has run correctly you should be able to type

  NOT do this if you are upgrading an existing installation -- the upgrade

662
  <pre><b>ant register-schemas</b></pre> 
663
  <p>This command registers the EML DTDs' and schemas' location in the 
664
  metacat server.  Your database username and password have to be set correctly
665
  for this to work.  Also, if for some reason running this script from ant
666
  does not work, you could instead try running "build/src/loaddtdschema.sql"
667
  from your sql utility (but be sure to use the version in the 'build' directory
668
  that has been customized for your installation).
669
  </p>
670
  <p class="header"><h2>Upgrading SQL Scripts</h2></p>
671
  <p>
672
    If you have an existing metacat installation, you should not run the install
673
    script because it will replace all of the older tables with new, empty 
674
    copies of the tables.  Thus you would lose your data!  Instead, you can 
675
    run some upgrade scripts that will change the table structure as needed for
676
    the new version.  If you are skipping versions, run each upgrade script
677
    for the intermediate versions as well.  Currently the upgrade scripts are:
678
   </p>
679
    <ul>
680
      <li>build/src/upgrade-db-to-1.2.sql</li>
681
      <li>build/src/upgrade-db-to-1.3.sql</li>
682
      <li>build/src/upgrade-db-to-1.4.sql</li>
683
      <li>build/src/upgrade-db-to-1.5.sql</li>
684
      <li>build/src/upgrade-db-to-1.6.sql</li>
685
      <li>build/src/upgrade-db-to-1.7.sql</li>
686
      <li>build/src/upgrade-db-to-1.7.1.sql</li>
687
    </ul>
688
   <p>
689
    For example, if you had an existing metacat 1.4 installation and you were upgrading 
690
    to metacat 1.7, you would need to run three scripts in sequence:
691
    upgrade-db-to-1.5.sql, upgrade-db-to-1.6.sql, and upgrade-db-to-1.7.sql. 
692
    However, if you were starting from a Metacat 1.6
693
    installation, you would only need to run the upgrade-db-to-1.7.sql script.
694
    <em>Be sure to use the version of the scripts from the 'build/src' directory: they
695
    are customized for your installation in that directory.</em>
696
   </p>
697
  </p>
698
  <h2>Restart Tomcat</h2>
699
  <p>
700
   Once you have successfully installed Metacat, there is one more step.  Tomcat
701
   (and Apache if you have Tomcat integrated with it) must be restarted.  To do
702
   this, login as the user that runs your tomcat server (often "tomcat"),
703
   go to $CATALINA_HOME/bin and type:
704
   <pre>
705
   ./shutdown.sh 
706
   ./startup.sh 
707
   </pre>
708
   In the Tomcat startup messages you should see something in the log file like:
709
   <pre>
710
	Metacat: [WARN]: Metacat (1.7.0) initialized. [edu.ucsb.nceas.metacat.MetaCatServlet]
711
   </pre>
712
   If you see that message Tomcat is successfully loading the Metacat servlet.
713
   Next, try to run your new servlet.  Go to a web browser and type:
714
   <pre>http://yourserver.yourdomain.com/yourcontext/</pre>
715
   You should substitute your context name for "yourcontext" in the url above.
716
   If everything is working correctly, you should see a query page followed
717
   by an empty result set.  Note that if you do not have Tomcat integrated with
718
   Apache you will probably have to type
719
   <pre>http://yourserver.yourdomain.com:8080/yourcontext/</pre>
720
  </p>
721
  <p><b>Troubleshooting</b>: If you see something like java.lang.InternalError: 
722
  Can't connect to X11 window server using 'yourservanme:0.0' as the value of the DISPLAY variable.
723
  <p>You should add this line: 
724
  <b>JAVA_OPTS="-Djava.awt.headless=true $JAVA_OPTS"</b> at the first line of
725
  catalina.sh file in tomcat bin directory. The reason is that GeoServer uses X11 windows to draw graphics.
726
  </p>
727
  
728
  <h2>Deploy wsdl file (Only for EarthGrid-enabled Metacat installation) </h2>
729
  <p>
730
   Once Tomcat is running successfully, there is another step for EarthGrid-enabled Metacat installation. 
731
   In metacat directory, type:
732
   <pre><b>ant deploy-ecogrid</b></pre> 
733
   It will generate wsdl files for EarthGrid services.
734
