The gtm_log environmental variable specifies a directory where the gtm_secshr_log file is stored. The gtm_secshr_log file stores information gathered in the gtmsecshr process. Fidelity recommends that a system-wide default be established for gtm_log so that gtmsecshr always logs its information in the same directory, regardless of which user's GT.M process invokes gtmsecshr.
