log_full shell script (Informix UNIX
specific term)
A script provided by ON-Bar that you
can use to start backing up logical-log
files when OnLine Server issues a log-
full event alarm. The Informix
ALARMPROGRAM configuration
parameter defaults to the
<INFORMIXDIR>/etc/log_full.sh,
where <INFORMIXDIR> is the OnLine
Server home directory. If you do not
want logical logs to be backed up
continuously, set the
ALARMPROGRAM configuration
parameter to <INFORMIXDIR>/etc/
no_log.sh.
logging level
The logging level determines the

transactions that have not been
