Logging Errors
All errors return both in your programs and in the log files. When any of
the OSI layers have an error, the error propagates up the stack, creating
an error at each layer. The number that identifies the error is called a log
instance. For example, if an error occurs at the Presentation layer, a
related error also occurs at the Application layer. The same log instance
occurs at least twice, identifying the related errors at both layers.
If you are unable to resolve errors returned in the user program, refer to
the log file for additional error information, such as program status. This
information may help you resolve the error or you may use it when
calling an HP support representative or referencing the OSI Planning
and Troubleshooting Guide.
Log classes include DISASTER, ERROR, WARNING, and
INFORMATIVE cases.
