HP Integrity NonStop J-Series - Manual (Page 187)

NOTE: To view the complete configuration snippet of the hibernate.cfg.xml file, see “JDBC
Configuration” (page 227) .
Closing the Session
Once the database operation is complete, close the session to deallocate the memory.
Add the following line of code when you complete the database operation.
session.close();
Configuring JDBC Type 4 Driver for SQL/MX Database using hibernate.properties
To complete the database operation in a Hibernate application using the JDBC Type 4 driver for
the SQL/MX database, complete the following steps:
1. Specifying the JDBC Type 4 Driver for SQL/MX Database
2. “Defining the Connection URL” (page 187)
3. “Establishing the Connection” (page 187)
4. “Defining the Hibernate Dialect for SQL/MX Database” (page 187)
5. “Opening a Session for Database Operation” (page 187)
6. “Specifying the Mapping Resources” (page 188)
7. “Closing the Session” (page 188)
Specifying the JDBC Type 4 Driver for SQL/MX Database
To specify the JDBC Type 4 driver for SQL/MX database, enter
com.tandem.t4jdbc.SQLMXDriver
as the JDBC Type 4 driver class for the SQL/MX database
in the hibernate.properties file as shown:
hibernate.connection.driver_class com.tandem.t4jdbc.SQLMXDriver
Defining the Connection URL
After you have specified the JDBC Type 4 driver, enter the location of the SQL/MX server. URLs
referring to SQL/MX use the jdbc: protocol and have the server host, port number embedded
within the URL.
To define the connection URL, enter jdbc:t4sqlmx://Address>:
as the connection URL for the SQL/MX database in the
hibernate.properties file as shown:
hibernate.connection.url jdbc:t4sqlmx://:
Establishing the Connection
To establish the connection, specify the username and password of your NonStop system in the
hibernate.properties
as shown.
hibernate.connection.username
hibernate.connection.password
Defining the Hibernate Dialect for SQL/MX Database
Enter org.hibernate.dialect.SqlmxDialect as the class name of a Hibernate dialect file
in the hibernate.properties file as shown below.
hibernate.dialect org.hibernate.dialect.SqlmxDialect
This property allows Hibernate to generate SQL optimized for SQL/MX database.
Opening a Session for Database Operation
To open a new session for database transaction, complete the following steps:
1. “Configuring SessionFactory in your Java Program” (page 188)
2. “Creating a New Session from the SessionFactory in Java” (page 188)
