# test_errors-seq.sh - test single-client errors due to bad client behavior
#
# SYNOPSIS:
#	test_errors-seq.sh
#
# DESCRIPTION
#	Performs test queries to check proper handling of error conditions.
#	- Errors on query level are handled by rasql.
#	- Errors on protocol level are triggered via a test program.
#	Ater provoking an error, it is tested whether the server remains
#	available fur same/other clients (whatever is appropriate).
#
# RESPONDING TO INCIDENT
#	none
#
# PROCEDURE
#	perform invocations, checks response and subsequent server availbility.
#
# PRECONDITIONS
# - rasql utility available
# - rasdaman up and running, with database having user/password as defined below
#
# RETURN CODES
        RC_OK=0         # everything went fine
        RC_ERROR=1      # something went wrong
#
RCTEXT_OK="OK"
RCTEXT_ERROR="NOT_OK"

# --- CONSTANTS -----------------------------------------------------

# name of script
