> Preventing Dead lock isses with jdbc persistence storage

>
> There are some random deadlocks occurs with jdbc persistence storage since
> Sandesha2 core access the table resources in different orders. Although these
> deadlocks are rear there is a possibility of getting them.
> As a solution for this problem we can lock the transactions at the storage
> level and let only one transaction to proceed. Then there is no chance for
> dead locks.
> This appears to be not a proper solution but it can prevent the deadlock
> occurrences.
> This may reduce the performance since it prevents parallel processing and is
> not solving the problem in a distributed environment.
