# WL#4677 Unique Server Ids for Replication Topology (UUIDs) #
#
# Each server has a UUID generated by server itself. It is stored in auto.cnf
# in @@DATADIR directory.
#
# @@SERVER_UUID is a readonly system variable, it is initialized as the
# server's UUID when starting. Users can get the server's UUID from
# @@SERVER_UUID.
#
# This test case tests whether the server's UUID can be generated, stored,
# initialized correctly.
