Transactions that haven't yet committed aren't written to the logical log so if you're about to check this at runtime it cannot be done in the same way. What you'd have to do is to monitor the transactions that are alive and maybe tie each to a client so that they can be rolled back if they get old without being finished. You can get a hold of the TransactionManager using:
(AbstractGraphDatabase)graphDb).getConfig().getTxModule().getTxManager(); which can be used to suspend/resume/rollback transactions. 2011/7/31 Felipe Oliveira Carvalho <felipe...@gmail.com> > How can I check if there are unfinished transactions?
