Subject Re: ActiveMQ is causing the database log to grow huge
Date Wed, 07 Sep 2016 05:43:42 GMT
Nothing says that the open transaction is the same transaction at time A
and time B; I've been repeatedly unable to truncate a table in Oracle (in
an application unrelated to ActiveMQ, but it illustrates the point) because
there were lots and lots of transactions per second against the table.  As
such, your conclusion/assumption that there's a single open transaction
that remains open for a long period of time may be inaccurate.  (Or it may
not, but unless you've got something concrete to prove that the same
transaction is alive between the two points in time, I'd assume that's not
it.)  In either case, I'm not aware of a way to force a running broker to
commit any particular database connection.

I'd suggest you contact Blackboard for advice on how to manage their
application; they might have a way to suspend the system to allow the
broker's database to be cleaned up.
