Purpose

Scope

Some users report intermittent errors like the following, occurring under heavy load in the Production environment:

oracle.jbo.SQLStmtException:
JBO-27120: SQL error during query execution. Statement: <SQL Statement>
(...)
java.sql.SQLException: Missing IN or OUT parameter at index:: <index number>

or

JBO-30003: The application pool (AppModuleLocal) failed to checkout an application module

due to the following exception:

oracle.jbo.JboException: JBO-29000: Unexpected exception caught:
oracle.jbo.common.UnknownSQLTypeException, msg=JBO-25000: Unknown SQL type: null


These errors are difficult to diagnose as developers cannot reproduce in the Development or Test environments.
