SENTRY User ’ s Guide Introduction - 9 Fitzgerald & Long Our recommendation is that you create a userid called sentry with the UID of 0 (zero). This user will have “ sentry ” as its “home” directory and will invoke the database on login.
Introduction - 10 SENTRY User ’ s Guide Fitzgerald & Long This is a safety precaution. SENTRY is a very powerful tool and should only be used by the System Administrator or his designee. SENTRY is designed to be a single user utility. Therefore, only one user at a time is allowed into SENTRY.
SENTRY User ’ s Guide Introduction - 11 Fitzgerald & Long wish to send the report to a specific printer, form or destination use the SETPTR command to set your printer parameters before executing this selection. After performi ng these steps your SENTRY database reflects the actual state of your system.
