Logging JDBC Calls in Payara Micro

Payara Micro supports SQL Tracing which brings powerful operational diagnostics to your micro-services platform.

Enabling Logging JDBC Calls

To enable SQL Tracing of JDBC on applications deployed on Payara Micro, use can use the annotation or deployment descriptor methods described below.

Application Deployment

In Java EE 7+ applications, a JDBC data source can be deployed by adding the @DataSourceDefinition annotation to a managed component (like and @Stateless EJB bean for example). The Log JDBC Calls setting can be configured using this annotation as well:

@DataSourceDefinition(
    name = "java:app/MyApp/MyDS",
    className = "org.h2.jdbcx.JdbcDataSource",
    url = "jdbc:h2:mem:test",
    properties = {"fish.payara.log-jdbc-calls=true"})

The Data source definition can also be added to a deployment descriptor of an application, for example in the web.xml standard deployment descriptor:

<data-source>
   <name>java:global/ExampleDataSource</name>
   <class-name>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</class-name>
   <server-name>localhost</server-name>
   <port-number>3306</port-number>
   <database-name>mysql</database-name>
   <user>test</user>
   <password>test</password>
   <!-- Example of how to use a Payara specific custom connection pool setting -->
   <property>
       <name>fish.payara.log-jdbc-calls</name>
       <value>true</value>
   </property>
</data-source>

or in the definition of a jdbc-connection-pool in a payara-resources.xml file:

<jdbc-connection-pool name="examplePool"
        res-type="javax.sql.DataSource"
        datasource-classname="org.h2.jdbcx.JdbcDataSource" log-jdbc-calls="true">
    <property name="user" value="test"/>
    <property name="password" value="test"/>
    <property name="url" value="java:global/ExampleDataSource"/>
</jdbc-connection-pool>

This can also be done in the creation of a JDBC Connection Pool with the --logjdbccalls option.

asadmin create jdbc-connection-pool --datasourceclassname org.h2.jdbcx.JdbcDataSource --restype javax.sql.XADataSource --logjdbccalls=true examplePool
