7 Message Handling
This section describes how to manage error messages that the TDP generates. It also
describes how to use the RscErrorInfo function to return API errors and describes
types and severities of API errors.
Log Events
The TDP sends RSC/MP error messages to one of these locations:
•
System error and critical error messages are sent, by default, to the Distributed
Systems Management (DSM) event collector ($0) or to a log file that you create.
•
Log event messages are sent to one of these files:
°
The DSM event collector ($0, the default).
°
A spooler collector (for example, $S).
°
An unstructured disk file that you create (for example, $DATA.RSC.ERRLOG,
see Error Return Codes From the Workstation API on page 7-3). There is no
default log file.
•
A terminal that is available for output.
RSC/MP applications have the following classes of log events:
•
Workstation API event messages that are sent to a log file that you create.
•
Communications subsystem messages returned by RSC/MP on the workstations.
Error Messages Reported From the NonStop
Host
The TDP sends critical RSC/MP error messages, by default, to a log file only if the log
file has been established by the RSCCOM LOGOPEN command. This process does
not require configuration.
For more information about setting up optional log files and for descriptions of event
types for each object in the TDP, see the Remote Server Call (RSC/MP) Installation
and Configuration Guide.
