ZCOM Message Logging and Error/Status Codes
Introduction
Chapter 116
Introduction
The ZCOM subsystem provides a centralized message logging
mechanism to allow the ACC software components to log runtime
messages to text files. The different subsystems log messages to indicate
their normal operations and the errors they encountered. Sometimes the
messages may contain vital information for trouble-shooting runtime
problems. The messages are first queued up in the kernel memory and
are extracted by the zmlog utility, which will then log the messages in a
readable text format (typically in /var/opt/acc/log/<day>.tlog), and
optionally save them in binary files in case further processing is
required. These messages may also be displayed on the system console.
Refer to the ACC Utilities Reference Guide for complete details on zmlog
and the message log files.
In addition to the logged messages, the ZCOM APIs (providing
programmatic access to the ZCOM features) may also return ZCOM
error codes and status codes to indicate the exception condition the
system encountered while processing the API request. When
appropriate, some log messages also include the ZCOM error/status
codes for troubleshooting purposes.
