Informational messages on UNIX systems

As the TimesTen daemon operates, it generates error, warning, informational and debug messages for TimesTen system administration and for debugging applications. At installation time, you determine whether these messages go into a file or to the syslog facility.

For root installs, TimesTen logs daemon messages using the LOG_USER facility defined by syslog, by default.

To specify the syslog facility used to log TimesTen Daemon and subdaemon messages, on a separate line of the ttendaemon.options file add:

-facility name

Possible name values are: auth, cron, daemon, local0-local7,lpr, mail, news, user, or uucp.

The syslog facility allows messages to be routed in a variety of ways, including recording them to a file. The disposition of messages is under the control of the configuration file, /etc/syslog.conf

Entries in the syslog.conf file contain two columns. The first column contains a list of the types of messages to log to a particular file. The second column contains the name of the log file. A tab appears between the message type and file name. Each entry in the syslog.conf file has the format:

message_type file_name. Message types are specified in two parts:

subsystem-facility.severity-level

Depending on the configuration specified in that file, messages can be logged into various files. For the TimesTen daemon, specify the message types: user.debug, user.info, user.warn and user.err. You can also use the wildcard character * to represent the subsystem- facility. Since debug messages are ranked highest, specifying *.debug or user.debug is sufficient in preparing a file for the daemon log. In a message type list, delimit items by semi-colons. For example:
