Node database

Configuring the node database
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
H2
|
|
--
|
|
By default, nodes store their data in an H2 database. See :doc:`node-database-access-h2`.
|
|
|
|
Nodes can also be configured to use PostgreSQL and SQL Server. However, these are experimental community contributions.
|
|
The Corda continuous integration pipeline does not run unit tests or integration tests of these databases.
|
|
|
|
PostgreSQL
|
|
----------
|
|
Nodes can also be configured to use PostgreSQL 9.6, using PostgreSQL JDBC Driver 42.1.4. Here is an example node
|
|
configuration for PostgreSQL:
|
|
|
|
.. sourcecode:: groovy
|
|
|
|
dataSourceProperties = {
|
|
dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
|
|
dataSource.url = "jdbc:postgresql://[HOST]:[PORT]/postgres"
|
|
dataSource.user = [USER]
|
|
dataSource.password = [PASSWORD]
|
|
}
|
|
database = {
|
|
transactionIsolationLevel = READ_COMMITTED
|
|
schema = [SCHEMA]
|
|
}
|
|
|
|
Note that:
|
|
|
|
* The ``database.schema`` property is optional
|
|
* The value of ``database.schema`` is not wrapped in double quotes and Postgres always treats it as a lower-case value
|
|
(e.g. ``AliceCorp`` becomes ``alicecorp``)
|
|
* If you provide a custom ``database.schema``, its value 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.
|
|
|
|
SQLServer
|
|
---------
|
|
Nodes also have untested support for Microsoft SQL Server 2017, using Microsoft JDBC Driver 6.2 for SQL Server. Here is
|
|
an example node configuration for SQLServer:
|
|
|
|
.. sourcecode:: groovy
|
|
|
|
dataSourceProperties = {
|
|
dataSourceClassName = "com.microsoft.sqlserver.jdbc.SQLServerDataSource"
|
|
dataSource.url = "jdbc:sqlserver://[HOST]:[PORT];databaseName=[DATABASE_NAME]"
|
|
dataSource.user = [USER]
|
|
dataSource.password = [PASSWORD]
|
|
}
|
|
database = {
|
|
transactionIsolationLevel = READ_COMMITTED
|
|
schema = [SCHEMA]
|
|
}
|
|
jarDirs = ["[FULL_PATH]/sqljdbc_6.2/enu/"]
|
|
|
|
Note that:
|
|
|
|
* The ``database.schema`` property is optional and is ignored as of release 3.1.
|
|
* Ensure the directory referenced by jarDirs contains only one JDBC driver JAR file; by the default,
|
|
sqljdbc_6.2/enu/contains two JDBC JAR file for different Java versions.
|
|

Node database tables
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
By default, the node database has the following tables:
