James Taylor commented on PHOENIX-4096:
---------------------------------------
There are about 20 more tests derived from BaseClientManagedTimeIT classes that
need to be converted before we can disallow DML and DDL on connections that set
CURRENT_SCN. See my patch for ones I've already converted - pretty
straightforward - just use unique table names and get rid of usage of
CURRENT_SCN as these tests don't need it. If you can help, then please indicate
which tests you're converting so we don't duplicate our efforts,
[~vincentpoon], [~samarthjain], [~aertoria], [~tdsilva].

> We should make a connection read-only if CURRENT_SCN is set. It's really a
> bad idea to go back in time and update data and it won't work with secondary
> indexing, potentially leading to your index and table getting out of sync.
> For testing purposes, where we need to control the timestamp, we should rely
> on the EnvironmentEdgeManager instead to control the current time.
