Subject [jira] [Updated] (DBCP-461) Prepared statements are not cached with XA
Date Wed, 18 May 2016 06:54:12 GMT

     [ https://issues.apache.org/jira/browse/DBCP-461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sailaja updated DBCP-461:
-------------------------
    Description: 
Prepared statements are not getting cached when I use XA datasource. 
Please find the below program :

public static void main(String[] args) throws Exception 
	{
		final TransactionManager transactionManager = TransactionManagerFactory
				.getTransactionManager();
		final PoolProperties poolProperties = new PoolProperties();
		
		SQLServerDataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
		dataSource.setUser("sa");
		dataSource.setPassword("$9Lserver");
		dataSource.setURL("jdbc:sqlserver://sdwivedi63ks022:1433;sendStringParametersAsUnicode=false");
		dataSource.setDatabaseName("himalaya");
		poolProperties.setDataSource(dataSource);
		
		final String jdbcInterceptors = "org.apache.tomcat.jdbc.pool.interceptor.StatementCache(prepared=true,callable=true)";
		poolProperties.setJdbcInterceptors(jdbcInterceptors);
		final org.apache.tomcat.jdbc.pool.DataSource pooledOracleDatasource = new org.apache.tomcat.jdbc.pool.XADataSource(
				poolProperties);
		final javax.sql.DataSource oracleDataSource = new org.apache.openejb.resource.jdbc.managed.xa.ManagedXADataSource(
				pooledOracleDatasource, transactionManager,
				TransactionProvider.getTransactionSynchronizationRegistry());
		Connection connection = oracleDataSource.getConnection();
		for(int i=0; i<50; i++)
		{
			PreparedStatement preparedStatement = connection.prepareStatement("insert into MyTableNew
values (" + i + ")");
			System.out.println(preparedStatement.getClass().getName());
			preparedStatement.execute();
			preparedStatement.close();
		}
		connection.close();
	}

If I run the above program, the output I see is:
	com.sun.proxy.$Proxy11

If I just change the above program to use XA datasource, i.e.
Change the following line
		SQLServerDataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
				To
		SQLServerXADataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerXADataSource();
The output is :
	com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement



  was:
public static void main(String[] args) throws Exception 
	{
		final TransactionManager transactionManager = TransactionManagerFactory
				.getTransactionManager();
		final PoolProperties poolProperties = new PoolProperties();
		
		SQLServerDataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
		dataSource.setUser("sa");
		dataSource.setPassword("$9Lserver");
		dataSource.setURL("jdbc:sqlserver://sdwivedi63ks022:1433;sendStringParametersAsUnicode=false");
		dataSource.setDatabaseName("himalaya");
		poolProperties.setDataSource(dataSource);
		
		final String jdbcInterceptors = "org.apache.tomcat.jdbc.pool.interceptor.StatementCache(prepared=true,callable=true)";
		poolProperties.setJdbcInterceptors(jdbcInterceptors);
		final org.apache.tomcat.jdbc.pool.DataSource pooledOracleDatasource = new org.apache.tomcat.jdbc.pool.XADataSource(
				poolProperties);
		final javax.sql.DataSource oracleDataSource = new org.apache.openejb.resource.jdbc.managed.xa.ManagedXADataSource(
				pooledOracleDatasource, transactionManager,
				TransactionProvider.getTransactionSynchronizationRegistry());
		Connection connection = oracleDataSource.getConnection();
		for(int i=0; i<50; i++)
		{
			PreparedStatement preparedStatement = connection.prepareStatement("insert into MyTableNew
values (" + i + ")");
			System.out.println(preparedStatement.getClass().getName());
			preparedStatement.execute();
			preparedStatement.close();
		}
		connection.close();
	}

If I run the above program, the output I see is:
	com.sun.proxy.$Proxy11

If I just change the above program to use XA datasource, i.e.
Change the following line
		SQLServerDataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
				To
		SQLServerXADataSource dataSource = new com.microsoft.sqlserver.jdbc.SQLServerXADataSource();
The output is :
	com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement
