Sylinsic opened a new pull request, #137:
URL: https://github.com/apache/openjpa/pull/137
OracleDictionary utilises the getUnqualifiedName method for retrieving
tables, but not for indexes or foreign keys.
As a result, openjpa is unable to locate indexes and foreign keys that were
created on a previous initialisation, causing openjpa to attempt to create them
again. Oracle throws an error when you attempt to do this, which causes
exceptions to be thrown in openjpa.
Adding getUnqualifiedName to the get index and foreign keys method
remediates this issue, as openjpa can now retrieve the previously created
indexes and foreign keys from the database.
Demonstration:
This can be demonstrated by starting up an apache syncope installation
(which utilises openjpa) with an oracle database.
The first start will fully initialise the database using OpenJPA as expected.
Upon restart of the syncope instance, OpenJPA attempts (and fails) to 'add'
the foreign keys and indexes, as it does not recognise that they are already
present.
Demo docker-compose.yml:
`
networks:
openjpa:
services:
db:
container_name: db
image: gvenzl/oracle-free:23-slim
restart: always
environment:
ORACLE_PASSWORD: syncope
APP_USER: syncope
APP_USER_PASSWORD: syncope
networks:
- openjpa
syncope:
container_name: syncope
depends_on:
- db
image: apache/syncope:4.0.0
ports:
- "18080:8080"
restart: always
environment:
SPRING_PROFILES_ACTIVE: docker,oracle
DB_URL: jdbc:oracle:thin:@//db:1521/FREEPDB1
DB_SCHEMA: syncope
DB_USER: syncope

Commands for demo:
1. docker compose up -d
2. docker logs -f syncope
- Wait for 'Started SyncopeCoreApplication in XX.XXX seconds' to appear
in syncope logs. At this point, the database will have been fully initialised
by OpenJPA
4. docker stop syncope
5. docker start syncope
6. docker logs -f syncope
- Observe logs of syncope, which will indicate the failure to create
foreign keys (and subsequently a container restart due to syncope failing to
fully start
N.b. JIRA issue will be opened once my apache JIRA account is created.
