How IvyEntityManager hanldes transaction of persistence?

Question

My current project have 8 modules, it will deploy 8 Process Model Versions in Ivy Application, I set maximum connection of database is 5. But when I run my app, it created more than 5 so it make my app stopped, when I increased number of connection, It worked normally, and I saw it created 8 connections. Why?

I am using IvyEntityManager to control transaction of entities. The problem is Ivy opened connection and retain it, not closes after I do operations(e.g merge...). So what IvyEntityManage does?

If the IvyEntityManager is used in IvyScript e.g.:

ivy.persistence.<persistence unit name>.merge(...)
ivy.persistence.<persistence unit name>.persiste(...)
...

Then an connection and transation is created and before the method returns the transaction is closed and the connection goes back to the connection pool.
