    • structure dump optionally (database.yml environment has db_stored_code: yes) extracts packages, procedures, functions, views, triggers and synonyms
    • automatically generated too long index names are shortened down to 30 characters
    • create tables with primary key triggers
    • use 'set_sequence_name :autogenerated' for inserting into legacy tables with trigger populated primary keys
    • access to tables over database link (need to define local synonym to remote table and use local synonym in set_table_name)
    • [JRuby] support JDBC connection using TNS_ADMIN environment variable and TNS database alias
    • changed cursor_sharing option default from 'similar' to 'force'
    • optional dbms_output logging to ActiveRecord log file (requires ruby-plsql gem)
    • use add_foreign_key and remove_foreign_key to define foreign key constraints (the same syntax as in http://github.com/matthuhiggins/foreigner and similar to http://github.com/eyestreet/active_record_oracle_extensions)
    • raise RecordNotUnique and InvalidForeignKey exceptions if caused by corresponding ORA errors (these new exceptions are supported just by current ActiveRecord master branch)
    • implemented disable_referential_integrity (enables safe loading of fixtures in schema with foreign key constraints)
    • use add_synonym and remove_synonym to define database synonyms
    • add_foreign_key and add_synonym are also exported to schema.rb
  • Bug fixes:
    • [JRuby] do not raise LoadError if ojdbc14.jar cannot be required (rely on application server to add it to class path)
    • [JRuby] 'execute' can be used to create triggers with :NEW reference
    • support create_table without a block
    • support create_table with Symbol table name
    • use ActiveRecord functionality to do time zone conversion
    • rake tasks such as db:test:clone are redefined only if oracle_enhanced is current adapter in use
    • VARCHAR2 and CHAR column sizes are defined in characters and not in bytes (expected behavior from ActiveRecord)
    • set_date_columns, set_datetime_columns, ignore_table_columns will work after reestablishing connection
    • ignore :limit option for :text and :binary columns in migrations
    • patches for ActiveRecord schema dumper to remove table prefixes and suffixes from schema.rb

  • Bug fixes:
    • Fixed after_save callback addition for session store in ActiveRecord version 2.0.2
