DB2 error (DSRA0010E: SQL State = 07006, Error Code = -301) when using DB2 Universal JDBC Driver (db2jcc.jar) with Entity Bean

Technote (troubleshooting)


In EJB development, when using the IBM DB2 Universal JDBC Driver (db2jcc.jar), a call stack error occurs that does not happen when using the DB2 Legacy CLI-based Type 2 JDBC Driver (



[9/6/05 10:27:10:598 EDT] 00000038 DataAccessReq E   PMGR0000E: Call stack: PMGR6022E: Error using adapter to create or execute an Interaction.
at Source)
Caused by: java.sql.SQLException: The value of input host variable or parameter number "1" cannot be used because of its data type.DSRA0010E: SQL State = 07006, Error Code = -301


This error might result if an EJB attribute of type byte array([]) is mapped to a CHARACTER FOR BIT DATA or VARCHAR FOR BIT DATA field.

By default, the deferPrepares Custom Property of the DB2 data source is set to true which, in this case, causes the error.

Resolving the problem

Use the explicit data type conversion for input parameters, as the generated code is using it. This can be accomplished by setting the Custom Property deferPrepares on the data source to false.

To change this property on the data source, use the administrative console for the version 6 WebSphere Test Environment or a stand-alone WebSphere Application Server.

For the version 5.x WebSphere Test Environment use the Server Configuration Editor provided by Rational Application Developer to set this value on the data source.
