Connection Errors
Connection errors can occur for a variety of reasons. For example, a failure in any of the internal connections described in
How Connection Between the Application and DBMS Server Is Established results in a connection error.
How connection errors are reported depends on where the failure occurs. If failure occurs:
• At the local instance, errors are reported directly to the user interface program or the application.
• Between the local and remote instances, for example, when attempting to connect from the local Communications Server to the remote Communications Server, errors go to the local errlog.log file as well as to the application.
• At the server installation, errors are reported to both the local and remote errlog.log file and to the application.
