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
