263
   Installing Metacat requires a server running an SQL92 compliant database
264
   (Oracle 8i or Postgresql recommended) with at least 128MB RAM, and a Pentium III class
265
   processor or higher.  The amount of disk space required depends on the
266
   size of your RDBMS tablespace (which should be at least 10 MB, 
267
   however Metacat itself requires only about 1 MB of free space after 
268
   installation).  These instructions assume a Linux environment but may
269
   work on other UNIX type environments, however this has not been tested.
270

272
  <a name="AdditionalRequiredSoftware"></a><div class="header2">Additional Required Software</div>
273
  <p>
274
   The server on which you wish to install Metacat must have the following
275
   software installed and running correctly before attempting to install
276
   Metacat.
277
   <ul>
278

       <p class="emphasis">Note: For a more robust web serving environment,

       Apache web server should
285
       be installed along with Tomcat and the two should be integrated

<a name="AdditionalSoftwareSetup"></a><div class="header1">Additional Software Setup</div>
292
  <a name="AdditionalSoftwareJava"></a><div class="header2">Java</div>
293
  <p>You'll need a recent Java SDK; J2SE 1.4.2 or later is required.  The latest metacat release
294
  has been tested most extensively with <a href="http://java.sun.com/j2se/1.5.0/">J2SE 5.0</a>
295
  and this is the recommended version.
296
  Make sure that JAVA_HOME environment variable is properly set and that both
297
  java and javac are on your PATH. 
298
  </p>
299
  <a name="AdditionalSoftwareOracle"></a><div class="header2">Oracle 8i</div>
300
  <p>The Oracle RDBMS must be installed and running as a daemon on the system.
301
   In addition the JDBC listener must be enabled.  You can enable it by
302
   logging in as your Oracle user and typing the following:</p>
303
   
304
     <div class="code">lsnrctl start</div>
305
     
306
   <p>Your instance should have a table space of at least 5 MB (10 MB or higher 
307
   recommended).  You should also have a username specific to Metacat
308
   created and enabled.  This user must have most normal permissions 
309
   including CREATE SESSION, CREATE TABLE, CREATE INDEX, CREATE TRIGGER, 
310
   EXECUTE PROCEDURE, EXECUTE TYPE, etc.  If an action is unexplainably 
311
   rejected by Metacat it is probably because the user permissions are not
312
   correctly set.</p>
313
   
314
  <a name="AdditionalSoftwarePostgreSQL"></a><div class="header2">PostgreSQL</div>
315
  <p>PostgreSQL can be easily installed on most linux distributions and on
316
  Windows (using cygwin) and Mac OS X.  Using Fedora Core or RedHat Linux,
317
  you can install the rpms for postgres and then run </p>
318
  
319
    <div class="code">/etc/init.d/postgresql start</div> 
320
    
321
  <p>in order to start the database. 
322
  On Ubuntu and other Debian-based Linux distributions, you can use the apt-get command
323
  to install postgres: 
324
    <div class="code">sudo apt-get install postgresql-8.0</div> and 
325
  then run 
326
    <div class="code">/etc/init.d/postgresql-8.0 start</div> to start.
327
  
328
  This initializes the data files.  You need to do a bit of configuration
329
  to create a database and set up a user account and allow internet access
330
  via jdbc.  See the postgres documentation for this, but here is a quick 
331
  start:
332
  <ul>
333
     <li>Switch to the "postgres" user account 
334
       <div class="code">sudo su - postgres</div></li>
335
     <li>Edit "data/pg_hba.conf", adding the following line to the file:<br>
336
       <div class="code">host   metacat  metacat      127.0.0.1         255.255.255.255   password</div>
337
     If your host uses IPv6 addresses, you may need this line instead:
338
       <div class="code">host   metacat  metacat      ::1               ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff password</div></li>
339
     <li>If you are using Postgresql pre-8.0, you must edit the "data/postgres.conf" file and uncomment and edit the line
340
     starting with "tcpip_socket" so that it reads 
341
       <div class="code">tcpip_socket = true</div></li>
342
     <li>Create metacat database by typing: 
343
       <div class="code">createdb metacat</div></li>
344
     <li>Log in using the postgres account and create a new "metacat" user account by typing:
345
       <div class="code">psql metacat</div> 
346
     <ul>
347
        <li>In postgres, run <div class="code">CREATE USER metacat WITH UNENCRYPTED PASSWORD 'apasswordyoulike';</div></li>
348
        <li>This creates a new account called metacat on the database named metacat</li>
349
        <li>Note: there are many ways to do this, so others such as using 
350
        ENCRYPTED passwords will work fine.</li>
351
     </ul>
352
     </li>
353
     <li>Exit the postgres account back to root and restart the postgres 
354
     database by typing:
355
       <div class="code">/etc/init.d/postgresql restart</div></li>
356
     <li>Test logging into the postgres db using the metacat account with 
357
     the following command: 
358
       <div class="code">psql -U metacat -W -h localhost metacat</div></li>
359
  </ul>

363
  <p>
364
   Ant is a Java based build application similar to Make on UNIX systems.  
365
   It takes in installation parameters from a file in the root installation
366
   directory named "build.xml".  The Metacat CVS module contains a default
367
   build.xml file that may require some modification upon installation.  Ant
368
   should be installed on the system and the "ant" executable shell script 
369
   should be available in the users path. The latest metacat release was tested with 
370
   Ant 1.6.5. <!-- We note that the current build is 
371
   not working with Ant 1.6.x, so you'll need to use an earler version.  We have 
372
   successfully used Ant 1.5.1, 1.5.2, and some earlier versions. -->

    Install Tomcat into the directory of your choice. The directory in which 
378
    you install Tomcat itself will be referred to as the &lt;tomcat_home&gt;.
379
    We recommend that you install Tomcat version 5.5.  More details about

<a name="DownloadingMetacat"></a><div class="header1">Download Metacat and Get War File</div>
384
 <p>There are several ways to wind up with a Metacat war file, which is needed for 
385
 installation.  These are: </p>
386
    <ul>
387
      <li>Download Metacat binary distribution - which will have a pre-built war file.</li>
388
      <li>Download Metacat source distribution - which will then need to be built in order to create a war file.</li>
389
      <li>Download Metacat source from SVN - which will then need to be built in order to create a war file.</li>
390
    </ul>
391
  <p>Since downloading the binary distribution is the easiest and most common install, it
392
  will be discussed here in detail.  Links to source download/build instructions are also
393
  included in case you would like to go that route.</p>

      In the Metacat section, for Linux based systems, select the link that looks like:</p>
399
	  <div class="code">metacat-bin-X.X.X.tar.gz</div>
400
	  <p>for Windows systems, select the link that looks like:</p>
401
	  <div class="code">metacat-bin-X.X.X.zip</div>
402
    <p>where X.X.X is the latest version of Metacat.  Choose to save the file locally.</p>
403
    <p>Extract the Metacat package files on Linux systems by typing:
404
      <div class="code">tar -xvzf metacat-bin-X.X.X.tar.gz</div>
405
    <p>or, on Windows, use your system unzip utility to extract the zip file.</p>
406
    <p>You should see a war file and several supporting files.  The location where these files
407
    were extracted will be refered to as the the &lt;metacat_package_dir&gt; for the remainder

  <p>Tomcat will look for it's application files (war files) in a configured directory.  
421
  This is typically the &lt;tomcat_home&gt;/webapps directory, but your instance of Tomcat may 
422
  be configured to look in a different directory.  We will refer to your Tomcat application directory 
423
  as &lt;tomcat_app_dir&gt;.</p>
424
     
425
  <a name="CreateMetacatDirs"></a><div class="header2">Create Metacat Directories</div>
426
    <p>Metacat uses a base directory to store such things as store data and metadata,
427
    temporary files and configuration backups.  This directory should be outside of the 
428
    Tomcat application directory since the application directory gets wiped out during an
429
    upgrade. Create the metacat utility base directory 
430
    by typing:</p>
431
      <div class="code">sudo mkdir <metacat_base_dir></div>
432
    <p>(Typically <metacat_base_dir> is '/var/metacat'.)  Remeber the directory you 
433
    choose, since you will be asked to configure Metacat to point to it after startup.</p>
434
    
435
    <p>Change the ownership of the directory by typing:</p>   
436
	  <div class="code">sudo chown -R &lt;tomcat_user&gt; /var/metacat</div>
437
    <p>where &lt;tomcat_user&gt; is the user that will start Tomcat.  If you are

497
    <p>Once you have successfully installed Metacat, there is one more step.  Tomcat
498
    (and Apache if you have Tomcat integrated with it) must be restarted.  To do
499
    this, login as the user that runs your tomcat server (often "tomcat"),
500
    go to &lt;tomcat_home&gt;/bin and type: </p>
501
   
502
      <div class="code">./startup.sh</div>
503
   
504
    <p>In the Tomcat startup messages you should see something in the log file like:</p>
505
   
506
      <div class="code">Metacat: [WARN]: Metacat (1.8.0) initialized. [edu.ucsb.nceas.metacat.MetaCatServlet]</div>
507
     
508
    If you see that message Tomcat has successfully loaded the Metacat servlet.
509
    Next, try to run your new servlet.  Go to a web browser and type:</p>
510
   
511
      <div class="code">http://yourserver.yourdomain.com/yourcontext/</div>
512
     
513
    <p>You should substitute your context name for "yourcontext" in the url above.
514
    If everything is working correctly, you should see a query page followed
515
    by an empty result set.  Note that if you do not have Tomcat integrated with
516
    Apache you will probably have to type</p>
517
