New Jdeveloper reproducable issues

New fusion and Jdeveloper version is available since last week.

I hear there are a lot of upgrates for SOA and BPM.
For ADF there are some enchancements for touch-enabled devices and bug fixes.

Some inderesting bug fixes in relase notes that we care about are:


reopening search and select dialog shows old data in the table


lov on query does not validate correctly and fires a blind query


lovs do not display changed values during the current session


af:inputlistofvalues in af:table only shows 25 rows


attributedescriptor.setreadonly(true) doesn't make the field readonly

I went through the posted bugs since in this blog and unfortunately most of them still reproduce in

Bad performance on quering Roles in weblogic Enterprise Manager

There are about 400 application roles defined in our application.
In a production environment there are about 1000 users that have groups of these roles so there are about 7000 role assignments.
We the policy store to be Database based for production environment (as it is recommended by documentation) in order to support clustering Weblogic environment.
Then the hole performance of Enterprise Manager was much worse than in file based. It took about 8 minutes to query the roles. This was happening also in every action , create, assign, remove role.
We run statistics and clean procedure in the database Policy Store but with no improvement.

So Service Request in oracle support is posted and they managed to reproduce it and post a bug: 13597913.

As a workaround we still use File Based Policy Store and synchronize system-jazn-date files between clustered servers.
