5 Error Messages, Diagnosis, and Reporting

These topics provide information about error messages and error codes specific to the Oracle Database Gateway for DRDA.

• Interpreting Gateway Error Messages
  The gateway architecture consists of different components and any component may detect and report an error condition while processing SQL statements that refer to one or more DRDA database tables.
• Mapped Errors
  Some SQL errors are returned from the DRDA server and are translated to an Oracle error code. This is needed when the Oracle instance or gateway provides special handling of an error condition.
• SQL Tracing and the Gateway
  When developing applications, it is often useful to be able to see the exact SQL statements that are being passed through the gateway.
