DSpace Oracle to PostgreSQL migration

The following procedure is only one example of migration done from Version 6.3 to Version 7.2.

It has been made using Ora2pg: https://ora2pg.darold.net/documentation.html

1. Install PERL: http://strawberryperl.com/
2. Download Ora2Pg: https://sourceforge.net/projects/ora2pg/
   • Unzip and access the file from the command line
3. Install Ora2Pg :
   perl Makefile.PL
   gmake && gmake install
   
   
4. ora2pg files will be installed in Strawberry directory
   • C:\Strawberry\perl\site\bin
   • C:\ora2pg
     Note : Do not use another path for Ora2Pg, otherwise configuration will not be made correctly in Strawberry Perl.
5. Rename file « C:\ora2pg\ora2pg_conf.dist » en « ora2pg.conf »
   1. Modify variable ORACLE_HOME to point to Oracle client
   2. Modify string connexion to Oracle DB :
      1. User/Password
      2. ORACLE_DSN, ORACLE_USER, ORACLE_PWD
   3. TYPE = TABLE,SEQUENCE,INSERT
   4. UUID_FUNCTION = gen_random_uuid
   5. STOP_ON_ERROR = 0
   6. FKEY_DEFERRABLE = 1
   7. DEFER_FKEY = 1
   8. MODIFY_TYPE 
      bitstream:size_bytes:bigint,checksum_history:check_id:bigint,checksum_history:checksum_expected:varchar,checksum_history:checksum_calculated:varchar,checksum_history:result:varchar,checksum_results:result_code:varchar,checksum_results:result_description:varchar,harvested_collection:oai_source:varchar,harvested_collection:oai_set_id:varchar,harvested_collection:harvest_message:varchar,harvested_collection:metadata_config_id:varchar,harvested_collection:harvest_start_time:timestamp with time zone,harvested_collection:last_harvested:timestamp with time zone,harvested_item:last_harvested:timestamp with time zone,harvested_item:oai_id:varchar,item:last_modified:timestamp with time zone,metadatavalue:text_lang:varchar(24),most_recent_checksum:expected_checksum:varchar,most_recent_checksum:current_checksum:varchar,most_recent_checksum:checksum_algorithm:varchar,most_recent_checksum:result:varchar,resourcepolicy:start_date:date,resourcepolicy:end_date:date,webapp:url:varchar,webapp:isui:integer
   9. REPLACE_AS_BOOLEAN NUMBER:1 CHAR:1
   10. DATA_TYPE NUMBER(*\,0):integer,VARCHAR2(2000):text
   11. SCHEMA DSPACE

Data migration procedure :

1. Open command line and move to following directory:
   C:\Strawberry\perl\site\bin.
2. Execute command line ora2pg to launch migration script from Oracle to SQL files for PostgresSQL objects creation.
3. Create a database on PostgreSQL server
   1. Use extension « pgcrypto »
