I have worked with JPA, over Java SE apps and Java Enterprise Applications inside a Application Server.
I have been in so many situations, since a problem of persisting a lot records (over 30,000) in just one process using RESOURCE_LOCAL transaction, persist the records by a parameter configured in a database, for example tell the app that need to persist each 1,000 records for avoiding to do it all in one step and overload the database that could not handle a lot of transactions in one step.
By other way, I also use JTA transactions, for middle weight CPU load transactions, the ones I do not need to handle, I let it to the Application Server using JTA for avoiding closing or opening and EntityManager.
