JDBC Connection from Oracle 11g Java Stored Procedure


JDBC Connection from Oracle 11g Java Stored Procedure

When using a Java Stored Procedure from within the Oracle 11g database, an attempt to open a connection to Teradata using the JDBC driver version 14 throws the following error.

Exception in thread "Root Thread" java.lang.NullPointerException

The connection code is:

create or replace and compile java source named "TDTest" as

  // Required class libraries.

  import java.sql.*;

  import oracle.jdbc.driver.*;

  import oracle.aurora.util.*;

  import com.teradata.jdbc.*;

  public class TDTest {

    public static int requestPriceDetails(String anchor, Integer rc, Integer sg, String upc, Integer req_id) throws SQLException {

      com.teradata.jdbc.TeraDriver td = new com.teradata.jdbc.TeraDriver();

      String tdConnectionString = "jdbc:teradata://tddev1cop1.ngco.com";

      Connection tdConn = DriverManager.getConnection(tdConnectionString, "user", "password");

      return 0;



The same code works run using the Oracle JVM on the same server. Is there a parameter that needs to be passed in this JVM?

Re: JDBC Connection from Oracle 11g Java Stored Procedure

First, the Oracle Database server-side JVM for Oracle Java Stored Procedures is not one of the supported environments for the Teradata JDBC Driver.

Having said that, this problem corresponds to a known issue -- JDBC DR 167176 Avoid NullPointerException at logon when System property "java.vm.info" is not set

We will be shipping a Teradata JDBC Driver change to address that issue soon. In the meantime, you can work around this Oracle JVM issue by setting the System property "java.vm.info" yourself to some value -- the actual value doesn't matter; it simply needs to be non-null.

System.setProperty("java.vm.info", "Oracle Database JVM");
