# stop_rasdaman.sh - shut down rasdaman server complex
#
# SYNTAX
#       stop_rasdaman.sh
#
# DESCRIPTION
#       This script terminates rasdaman.
#	First, all server processes are terminated. Then, the server
#	manager (rasmgr) is shut down.
#       To log in to the server, the external variable $RASLOGIN is expected to hold
#       an ID string (see rasdaman manual). If not found, a desperate last attempt is
#       made to login as rasadmin/rasadmin. If this fails, no servers are stopped at all.
#
# BE CAREFUL
#	By terminating rasdaman, all open transactions are aborted,
#	and their contents will be irretrievably lost!
#
# PRECONDITIONS
#       - need to have a rasdaman admin login either from $RASLOGIN or as rasadmin/rasadmin
#	- no open transactions or databases, they will be killed and transactions aborted
#
