@ -32,11 +32,19 @@ configuration for PostgreSQL:
Note that:
* Database schema name can be set in JDBC URL string e.g. currentSchema=myschema
* Database schema name can be set in JDBC URL string e.g. *currentSchema=my_schema*
* Database schema name must either match the ``dataSource.user`` value to end up
on the standard schema search path according to the
`PostgreSQL documentation <https://www.postgresql.org/docs/9.3/static/ddl-schemas.html#DDL-SCHEMAS-PATH>`_, or
the schema search path must be set explicitly for the user.
* If your PostgresSQL database is hosting multiple schema instances (using the JDBC URL currentSchema=my_schema)
for different Corda nodes, you will need to create a *hibernate_sequence* sequence object manually for each subsequent schema added after the first instance.
Corda doesn't provision Hibernate with a schema namespace setting and a sequence object may be not created.
Run the DDL statement and replace *my_schema* with your schema namespace:
.. sourcecode:: groovy
CREATE SEQUENCE my_schema.hibernate_sequence INCREMENT BY 1 MINVALUE 1 MAXVALUE 9223372036854775807 START 8 CACHE 1 NO CYCLE;
