Node database
Default in-memory database
By default nodes store their data in an H2 database.
You can connect directly to a running node's database to see its stored states, transactions and attachments as follows:
Download the h2 platform-independent zip, unzip the zip, and navigate in a terminal window to the unzipped folder
Change directories to the bin folder:
cd h2/binRun the following command to open the h2 web console in a web browser tab:
- Unix:
sh h2.sh - Windows:
h2.bat
- Unix:
Find the node's JDBC connection string. Each node outputs its connection string in the terminal window as it starts up. In a terminal window where a node is running, look for the following string:
Database connection URL is : jdbc:h2:tcp://10.18.0.150:56736/nodePaste this string into the JDBC URL field and click
Connect, using the default username and password.
You will be presented with a web interface that shows the contents of your node's storage and vault, and provides an interface for you to query them using SQL.
Standalone database
To run a node against a remote database modify node JDBC connection properties in dataSourceProperties entry and Hibernate properties in database entry - see :ref:`dataSourceProperties.
SQL Azure and SQL Server
Corda supports SQL Server 2017 (14.0.3006.16) and Azure SQL (12.0.2000.8). The minimum transaction isolation level database.transactionIsolationLevel is 'readCommitted'. The property database.schema is optional. Corda ships with Microsoft JDBC Driver 6.2 for SQLServer out-of-the-box.
Example node configuration for SQL Azure:
- dataSourceProperties {
dataSourceClassName = "com.microsoft.sqlserver.jdbc.SQLServerDataSource" dataSourceProperties.dataSource.url = "jdbc:sqlserver://[DATABASE_SERVER].database.windows.net:1433;databaseName=[DATABASE]; encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30" dataSourceProperties.dataSource.user = [USER] dataSourceProperties.dataSource.password = [PASSWORD]
} database { transactionIsolationLevel = "readCommitted" schema = [SCHEMA] }
