• PostgreSQL 8.3 to 8.4 PostgreSQL can be downloaded from the following location: http://www.postgresql.org/ . It is highly recommended that you try to work with Postgres 8.4 or greater, however 8.3 should still work. Unicode (specifically UTF-8) support must be enabled. This is enabled by default in 8.0+. Once installed, you need to enable TCP/IP connections (DSpace uses JDBC). In postgresql.conf: uncomment the line starting: listen_addresses = 'localhost'. Then tighten up security a bit by editing pg_hba.conf and adding this line: host dspace dspace 127.0.0.1 255.255.255.255 md5. Then restart PostgreSQL.
• Oracle 10g or greater Details on acquiring Oracle can be downloaded from the following location: http://www.oracle.com/database/. You will need to create a database for DSpace. Make sure that the character set is one of the Unicode character sets. DSpace uses UTF-8 natively, and it is suggested that the Oracle database use the same character set. You will also need to create a user account for DSpace (e.g. dspace) and ensure that it has permissions to add and remove tables in the database. Refer to the Quick Installation for more details.
  1. If the database server is not on the same machine as DSpace, you must install the Oracle client to the DSpace server and point tnsnames.ora and listener.ora files to the database the Oracle server.

  2. Wiki Markup
     You need to compile DSpace with an Oracle driver (ojdbc6.jar) corresponding to your Oracle version - update the version in _\[dspace-source\]/pom.xml_ E.g.:

     Code Block
     <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.3</version> </dependency>

  3. Wiki Markup
     You need to set the following in _\[dspace\]/config/dspace.cfg_ (or its _\[dspace-src\]_ equivalent):

     Code Block
     db.driver = oracle.jdbc.OracleDriver db.url = jdbc:oracle:thin:@database.host:1521/SID

     Where SID is the SID of your database defined in tnsnames.ora or you can use a full SID definition, e.g.:

     Code Block
     db.url = jdbc:oracle:thin:@(description=(address_list=(address=(protocol=TCP)(host=localhost)(port=1521)))(connect_data=(service_name=DSPACE)))

     Also set your own username and password:

     Code Block
     db.username = your_oracle_username db.password = your_oracle_password

  • NOTE: DSpace uses sequences to generate unique object IDs — beware Oracle sequences, which are said to lose their values when doing a database export/import, say restoring from a backup. Be sure to run the script etc/update-sequences.sql.
  • For people interested in switching from Postgres to Oracle, I know of no tools that would do this automatically. You will need to recreate the community, collection, and eperson structure in the Oracle system, and then use the item export and import tools to move your content over.
