#    NAME
#      workload_capture.pl
#
#    DESCRIPTION
#      This script will start a workload capture. It may involve restarting the
#      database before the capture.
#
#    NOTES
#      When restarting RAC, all nodes are first shut down and only one node is
#      started up. After capture begins, all the nodes will be started up.
#
#    MODIFIED   (MM/DD/YY)
#       keiwong  03/27/09 - include force shutdown option for RAC
#       keiwong  07/16/08 - don't use srvctl to start up db in restricted mode
#       keiwong  05/05/08 - handle non-ASCII value
#       keiwong  04/29/08 - add db_version and connect_descriptor parameters
#       keiwong  10/05/06 - Fix bug 5558757
#       keiwong  07/06/06 - Creation
