Installing Metacat requires a server running an SQL92 compliant database
|
|
63
|
(Oracle 8i 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.

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.

<p class="header">Java</p>
|
|
97
|
<p>You'll need a recent Java SDK; j2sdk1.4.2 or later is required. We haven't
|
|
98
|
tested with any of the 1.5.x versions yet, so probably best to stay with 1.4.x.
|
|
99
|
Make sure that JAVA_HOME environment variable is properly set and that both
|
|
100
|
java and javac are on your PATH.

|
<p class="header">Oracle 8i or Postgres</p>
|
|
103
|
<p><i>Oracle:</i><br>
|
|
104
|
The Oracle RDBMS must be installed and running as a daemon on the system.
|
|
105
|
In addition the JDBC listener must be enabled. You can enable it by
|
|
106
|
logging in as your Oracle user and typing the following:
|
|
107
|
<pre>lsnrctl start</pre>
|
|
108
|
Your instance should have a table space of at least 5 MB (10 MB or higher
|
|
109
|
recommended). You should also have a username specific to Metacat
|
|
110
|
created and enabled. This user must have most normal permissions
|
|
111
|
including CREATE SESSION, CREATE TABLE, CREATE INDEX, CREATE TRIGGER,
|
|
112
|
EXECUTE PROCEDURE, EXECUTE TYPE, etc. If an action is unexplainably
|
|
113
|
rejected by Metacat it is probably because the user permissions are not
|
|
114
|
correctly set.
|
|
115
|
</p>
|
|
116
|
<p><i>Postgres:</i><br>
|
|
117
|
Postgres can be easily installed on most linux distributions and on
|
|
118
|
Windows (using cygwin) and Mac OS X. Using Fedora Core or RedHat Linux,
|
|
119
|
you can install the rpms for postgres and then run
|
|
120
|
<code>/etc/init.d/postgresql start</code> in order to start the database.
|
|
121
|
This initializes the data files. You need to do a bit of configuration
|
|
122
|
to create a database and set up a user account and allow internet access
|
|
123
|
via jdbc. See the postgres documentation for this, but here is a quick
|
|
124
|
start:
|
|
125
|
<ul>
|
|
126
|
<li>Switch to the "postgres" user account and edit "data/pg_hba.conf", adding the following line to the file:<br>
|
|
127
|
<code>host metacat metacat 127.0.0.1 255.255.255.255 password</code></li>
|
|
128
|
<li>Edit the "data/postgres.conf" file and uncomment and edit the line
|
|
129
|
starting with "tcpip_socket" so that it reads
|
|
130
|
<code>tcpip_socket = true</code></li>
|
|
131
|
<li>Run <code>createdb metacat</code> to create a new database</li>
|
|
132
|
<li>Run <code>psql metacat</code> to log in using the postgres account and create a new "metacat" user account
|
|
133
|
<ul>
|
|
134
|
<li>In postgres, run <code>CREATE USER metacat WITH UNENCRYPTED PASSWORD 'apasswordyoulike';</code></li>
|
|
135
|
<li>This creates a new account called metacat on the database named metacat</li>
|
|
136
|
<li>Note: there are many ways to do this, so others such as using
|
|
137
|
ENCRYPTED passwords will work fine.</li>
|
|
138
|
</ul>
|
|
139
|
</li>
|
|
140
|
<li>Exit the postgres account back to root and restart the postgres
|
|
141
|
database with <code>/etc/init.d/postgresql restart</code></li>
|
|
142
|
<li>Test logging into the postgres db using the metacat account with
|
|
143
|
the following command:
|
|
144
|
<code>psql -U metacat -W -h localhost metacat</code></li>
|
|
145
|
</ul>
|
|
146
|

|
|
147
|
<p class="header">Ant</p>
|
|
148
|
<p>
|
|
149
|
Ant is a Java based build application similar to Make on UNIX systems.
|
|
150
|
It takes in installation parameters from a file in the root installation
|
|
151
|
directory named "build.xml". The Metacat CVS module contains a default
|
|
152
|
build.xml file that may require some modification upon installation. Ant
|
|
153
|
should be installed on the system and the "ant" executable shell script
|
|
154
|
should be available in the users path. We note that the current build is
|
|
155
|
not working with Ant 1.6.x, so you'll need to use an earler version. We have
|
|
156
|
successfully used Ant 1.5.1, 1.5.2, and some earlier versions.

<p class="header">Tomcat</p>

<p>

160
|
Install Tomcat into the directory of your choice. The directory in which
|
|
161
|
you install Tomcat itself will be referred to as the "$CATALINA_HOME".
|
|
162
|
We recommend that you install Tomcat version 4.0. More details about
|
|
163
|
Tomcat installation is available <a href=" http://jakarta.apache.org/tomcat/index.html">here</a>.

Once all of the prerequisite software is installed as described above,
|
|
175
|
the installation of Metacat can begin. First you must have a current
|
|
176
|
version of the source distribution of Metacat. You can get it two ways.
|
|
177
|
Authorized users can check it out of the NCEAS
|
|
178
|
<a href="http://www.nceas.ucsb.edu/cgi-bin/cvsweb.cgi/xmltodb/">CVS</a>
|
|
179
|
system. You'll need both the "metacat" module and the "utilities" module to
|
|
180
|
be checked out in sibling directories. The command is as follows:
|
|
181
|
<pre>mkdir knb-software</pre>
|
|
182
|
<pre>cd knb-software</pre>
|
|
183
|
<pre>cvs checkout -P metacat</pre>
|
|
184
|
<pre>cvs checkout -P utilities</pre>
|
|
185
|
Or you can
|
|
186
|
<a href="@server@/software/download.html">download</a> a gzipped tar file
|
|
187
|
from this site.
|

|
189
|
<p><h2>Edit <code>build.properties</code> File</h2></p>
|
|
190
|
<p>
|
|
191
|
Once you have either checked out or unzipped and untarred the source
|
|
192
|
distribution, you can begin the installation process. Change into the
|
|
193
|
metacat directory and edit the file called "<code>build.properties</code>". You will need
|
|
194
|
to change a number of configuration properties to match the setup on
|
|
195
|
your system.
|
|
196
|
</p>
|
|
197
|
<p>
|
|
198
|
The properties that you will likely need to change will include
|
|
199
|
<code>tomcat</code>, <code>tomcatversion</code>, <code>webapps</code>,
|
|
200
|
<code>context</code>, <code>server</code>, <code>httpserver</code>,

<code>cvsroot-alternate</code>, <code>default-style</code>, and
|
|
205
|
<code>administrators</code>.

Each is described in detail in the table below.

You now need to set up the table structure in your database. You can do
|
|
512
|
either do this using the ant build system, or by manually running the
|
|
513
|
scripts using a sql utility.
|
|
514
|
</p>
|
|
515
|
<p><b>WARNING: Do NOT run this on an existing metacat installation as it
|
|
516
|
will delete all of your data. If you have an existing metacat installation,
|
|
517
|
see the instructions for "Upgrading" below.</b></p>
|
|
518
|
|
|
519
|
<p>To run the scripts using ant, type <code>ant installdb</code>. This does
|
|
520
|
not work for postgres, so you'll need to run the xmltables-postgres.sql script
|
|
521
|
manually (see next paragraph).
|
|
522
|
</p>
|
|
523
|
<p>To run the scripts manually, change to the
|
|
524
|
metacat/build/src directory. Then run you RDBMS's SQL utility. In Oracle it is
|
|
525
|
SQLPlus. This tutorial assumes an Oracle database so this example is for
|
|
526
|
SQLPlus. Login as the oracle user that was set up for use with Metacat.
|
|
527
|
At the SQLPlus prompt type the following: <pre><b>@xmltables.sql;</b></pre>
|
|
528
|
For postgres, use a command like:
|
|
529
|
<code>psql -U metacat -W -h localhost -f build/src/xmltables-postgres.sql metacat</code>
|
|
530
|
</p>
|
|
531
|
<p>Either way,
|
|
532
|
you should see a bunch of output showing the creation of the Metacat table
|
|
533
|
space. The first time you run this script you will get several errors at the
|
|
534
|
beginning saying that you cannot drop a table/index/trigger because it
|
|
535
|
does not exist. This is normal. Any other errors besides this need to be
|
|
536
|
resolved before continuing. The script file name for PostgreSQL is
|
|
537
|
xmltables-postgres.sql and for Microsoft SQL server is
|
|
538
|
xmltables-sqlserver.sql.
|
|
539
|
</p>
|
|
540
|
<p>
|

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

|

562

<p>Once the tables have been created, you should also register the Ecological
|
|
563
|
Metadata Language (EML) DTDs and schemas. <b>However, note that you should
|
|
564
|
NOT do this if you are upgrading an existing installation -- the upgrade
|
|
565
|
scripts take care of it for you (see the next section).</b> If you are
|
|
566
|
installing new, you can register the schema documents by running:</p>
|
|
567
|
<pre><b>ant register-schemas</b></pre>
|
|
568
|
<p>This command registers the EML DTDs' and schemas' location in the
|
|
569
|
metacat server. Your database username and password have to be set correctly
|
|
570
|
for this to work.
|
|
571
|
</p>
|
|
572
|
<p class="header"><h2>Upgrading SQL Scripts</h2></p>
|
|
573
|
<p>
|
|
574
|
If you have an existing metacat installation, you should not run the install
|
|
575
|
script because it will replace all of the older tables with new, empty
|
|
576
|
copies of the tables. Thus you would lose your data! Instead, you can
|
|
577
|
run some upgrade scripts that will change the table structure as needed for
|
|
578
|
the new version. If you are skipping versions, run each upgrade script
|
|
579
|
for the intermediate versions as well. Currently the upgrade scripts are:
|
|
580
|
</p>
|
|
581
|
<ul>
|
|
582
|
<li>upgrade-db-to-1.2.sql</li>
|
|
583
|
<li>upgrade-db-to-1.3.sql</li>
|
|
584
|
<li>upgrade-db-to-1.4.sql</li>
|
|
585
|
</ul>
|
|
586
|
<p>
|
|
587
|
So, if you had an existing metacat 1.0 installation and you were upgrading
|
|
588
|
to 1.4, you would need to run all three scripts in sequence:
|
|
589
|
upgrade-db-to-1.2.sql, upgrade-db-to-1.3.sql, and upgrade-db-to-1.4.sql.
|
|
590
|
However, if you were starting from a Metacat 1.3.x
|
|
591
|
installation, you would only need to run the upgrade-db-to-1.4.sql script.
|
|
592
|
</p>
|
|
593
|
</p>
|
|
594
|
<h2>Restart Tomcat</h2>
|
|
595
|
<p>
|
|
596
|
Once you have successfully installed Metacat, there is one more step. Tomcat
|
|
597
|
(and Apache if you have Tomcat integrated with it) must be restarted. To do
|
|
598
|
this, login as the user that runs your tomcat server (often "tomcat"),
|
|
599
|
go to $CATALINA_HOME/bin and type:
|
|
600
|
<pre>
|
|
601
|
./shutdown.sh
|
|
602
|
./startup.sh
|
|
603
|
</pre>
|
|
604
|
In the Tomcat startup messages you should see something in log file like:
|
|
605
|
<pre>
|
|
606
|
MetacatServlet Initialize
|
|
607
|
Context log path="/metadata" :Metacat: init
|
|
608
|
MetacatServlet Initialize
|
|
609
|
</pre>
|
|
610
|
If you see that message Tomcat is successfully loading the Metacat servlet.
|
|
611
|
Next, try to run your new servlet. Go to a web browser and type:
|
|
612
|
<pre>http://yourserver.yourdomain.com/yourcontext/</pre>
|
|
613
|
You should substitute your context name for "yourcontext" in the url above.
|
|
614
|
If everything is working correctly, you should see a query page followed
|
|
615
|
by an empty result set. Note that if you do not have Tomcat integrated with
|
|
616
|
Apache you will probably have to type
|
|
617
|
<pre>http://yourserver.yourdomain.com:8080/yourcontext/</pre>
