Subject running simultaneous java programs which access derby datases
Date Tue, 01 Sep 2015 00:53:06 GMT

I have cloned strategies for the forex market which are actioned every four
hours on the hour.
i.e. each 4 hours each strategy goes thru a calculation process which
includes looking up data held in its own derby database

When I run just a single strategy everything seems OK but when I try and run
say 5 strategies simultaeously, accessing the derby databases causes

such as 'greedy' errors etc.

Each separate database has its own login etc.

My problem is that these databases are being accessed every 4 hours on the
hour and I think confusion is being caused as to which database is being
opened, accessed or closed...........

Sorry if my explanation is unclear :)

Any suggestions welcome............
