Replicating databases maintaining consitency

[nbarrera]

Hi,

I 've a system which provisioned data into a database..., today's requieriment is to have two databases and perform certain actions on both databases.

I 've achieved that by using a custom HibernateInterceptor combined with a custom implemntation of AbstractRoutingDatasource.


What I couldn't do is to rollback commit on database1 if action on database2 fails.

could anyone give me a hint on how to make the first transaction rollback if the second fails?

Here I detail the interceptors I got running on my system in order:

* HibernateInterceptor
* TransactionInterceptor

cheers, and thanks in advanced.

Since two different databases are involved you will have to use global (JTA) transactions. Please refer to Spring documentation for JTA configuration.
