# Listing 2: buc_server.ss: Back Up Check Utility, server:
# Execute the oncheck utility and find out when the last backup
# completed.  Build a datatime string, insert it into the remote_variables
# table, and return to buc_client.ss.
# This script is called by buc_client.ss.
# this shell script:
# 1) Initialize variables, check informix user, set TZ, etc.
# 2) Executes the oncheck -pr utility retrieving backup datetime.
# 3) Get the current datetime.
# 4) Format a string with the backup and current datetimes.
# 5) Insert formatted string into the remote_values table.
# 6) Return to buc_client.ss.
