                Hi PSFT ADMIN Team,

                asynchronous_error_monitor.sh script for Production

                Sorry, there was a problem in logging to the ${ORACLE_SIDD} Database. So, can not continue to check for asynchronous errors.
                Please do fix this issue on Priority. Escalate to the DBA Manager for any serious concerns.
