# TEST	sql001
# TEST	Test db_replicate using a simple SQL app.
# TEST
# TEST  Start db_replicate on master side and client side,
# TEST	and do various operations using dbsql on master side.
# TEST  After every operation, we will check the records on both sides,
# TEST  to make sure we get same results from both sides.
# TEST  Also try an insert operation on client side; it should fail.
