-# This test is for the commit blocker

-# the behaviour of the commit blocker hold true.
-#
-# a) transactions in progress are not committed until after the backup
-# b) transactions that are committing are allowed to commit
-# c) transactions that have not started are allowed to start but do not commit
-# d) non-transaction statements in progress are allowed to finish
-# e) non-transaction statements that have not started are blocked
-#
-# The results of the backup should show (based on statements above):
-#
-# a) Test result for this assumption: Not included in backup
-# b) Test result for this assumption: Included in backup
-# c) Test result for this assumption: Not included in backup
-# d) Test result for this assumption: Included in backup
-# e) Test result for this assumption: Not included in backup
-#
-# Note: the statements above assume statements that change data.
-#
-# The test shall run three sets of data manipulation statements.
-#
-# 1) transactional statments only
-# 2) non-transactional statements only
-# 3) mix of both transactional and non-transactional statements
