I see both of these Java patches available: Patch 33416120: Oracle JRE 8 Update 311 b31 Patch 33416120: Oracle JRE 8 Update 311 Can anyone tell me what the difference is? Thanks!
It is documented.
"The Oracle.connect() method defaults to a false setting of the auto-commit flag. However, it also has signatures to set it explicitly. In the Oracle JDBC implementation, the auto-commit flag defaults to true."
Oracle.connect()
false
true
Key Programming Considerations
Well, this is documentation for sqlj and first sentence just confirms what I said(that auto-commit by default should be false)
Just to clarify my original post:
When you retrieve jdbc connection in adf application(for example, in app module impl class), that connection already has autocommit=false (because framework will set this property)
Difference between adf 11.x and 12.x is in setting db proxy user (by using conn.openProxySession() ) :
In 11.x (which uses ojdbc6 driver) invocation of openProxySession() method will preserve autocommit=false
In 12.x (which uses ojdbc7 driver) invocation of openProxySession() method will reset autocommit to true (and adf app will not work correctly with this setting)

ojdbc7.jar is based on JDBC 4.1 and JDBC 4.1 still sets auto-commit to true by default.
"The default is for auto-commit mode to be enabled when the Connection object is
created."

Could auto commit be false for the PROXYTYPE_USER_NAME specified?
OracleConnection (Oracle Database JDBC Java API Reference)
CONNECTION_PROPERTY_AUTOCOMMIT_DEFAULT is true in both 11g and 12c.

Is setting of false documented?
