Error Messages
A.l GENERAL
This appendix describes the error messages written to the system
log during activation and operation of the network. Error
messages may be encountered at each software level in the
communications package. Error messages may also be encountered
when the communications warm start program is executed. Each of
the error messages are described separately in the following
paragraphs.
Error messages that occur when executing the applications
utilities are described in Section 5. Status codes and error
messages returned to applications programs are described in
Section 4.
All error messages written to the system log begin with the
common COMM ERROR (CC) format, where (CC) is a two-character level
or function identifier. The two-character code that is printed
with each message identifies the following:
