I am trying to pass an array object of type oracle.sql.ARRAY to Oracle stored procedure; most of the times I am successful at that. It was found after a customer reported an error that when the array had certain number of elements in it, the code failed. I didnt find out the exact threshold value at which the code broke. Upto around 1000 elements in the array it worked fine. At 1500 it failed. I am working with WebLogic Server 8.1 SP4, Oracle at client 22.214.171.124 and at server 126.96.36.199. I am using direct JDBC OCI connection and not the Weblogic connection pool. Below is the code which is causing the problem.
Even before the OracleCallableStatement is executed it breaks right at the setARRAY method.
The exception thrown is: Caused by: java.sql.SQLException: Invalid argument(s) in call at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269) at oracle.jdbc.dbaccess.DBItem.setArrayData(DBItem.java:262) at oracle.jdbc.dbaccess.DBDataSetImpl.setADTBindItem(DBDataSetImpl.java:2738) at oracle.jdbc.driver.OraclePreparedStatement.setARRAY(OraclePreparedStatement.java:1760) at com.pearson.report.persistence.StudentMasteryDAO.getStudentMasteryData(StudentMasteryDAO.java:116) ... 8 more
