You should be able to select the faster-but-slightly-less-secure /dev/urandom on Linux using:
Default /dev/urandom is configured, but as mentioned this is ignored by Java.
However, this doesn’t work with Java 5 and later (Java Bug 6202721). The suggested work-around is to use:
-Djava.security.egd=file:/dev/./urandom(note the extra ‘/./’)
You can also set in your environment like below in setDomainEnv.sh
Or at runtime:
It is Better to set the Database Time Spent Waiting (%)= 99 in Monitoring Templates , so that any new Database discovered will gets synced with the Template collection and changes the default 30% to 99%.
Verify that the DBA_THRESHOLDS in target database is updated.
i.e the below query should return no rows:
SELECT metrics_name, critical_value, warning_value, object_name, status
where metrics_name like '%Database Time Spent%';

TANI wanted to improve the efficiency of their business unit and help them make better decisions. As part of this goal TANI decided to upgrade the current campaign management application which is used to manage the online banner ad campaigns of their customers.
Specifically TANI’s goals in this upgrade were:
- Increase the data entry/modification speed in the application
- Improve the reporting capabilities in the application
- Improve the application’s UI with a fresh and modern look.
The core campaign information in the database spans three tables which are tied to each other in a master-detail-detail relationship. For any campaign, the data in the master row, the detail rows and the detail-detail rows must be validated, committed or rolled backed in the same logical transaction.
The current application did not support batch validation and commit of the entire campaign and therefore was prone to human errors.
Since Formspider has an integrated model layer that supports transactions, building a master-detail-detail screen which enforces data validation over three tables was a breeze. The Formspider application easily validates and commits updates to a campaign in the same logical transaction preventing data entry errors.
The Campaign Edit Screen
The master-detail-detail screen also greatly improved the data entry speed of the application because the user could edit the entire campaign information in one screen.
Reporting capabilities of the application also increased significantly thanks to the Formspider grid and its built-in features such as ordering, hiding and filtering of columns.
The Campaign Search Screen with Enhanced Reporting Capabilities
The new application featured new a brand new look&feel in harmony with TANI’s corporate colors. As with every Formspider application, the new campaign management application is a single page application functioning 100% with AJAX giving it the modern effect TANI desired.
New Fresh Look that matches TANI's Corporate Guidelines
Formspider enabled us to deliver TANI a high quality application that features a master-detail-detail data entry screen with validations spanning multiple tables with a fraction of the cost it would take using other technologies.
The application enabled TANI business units to work more efficiently and helped them make better decisions while serving their customers.
In a Chicago Tribune interview, he says:
I could be wrong, but science needs to cross a threshold and explain why a monkey typing infinitely would never type the works of Shakespeare.
Well, I could be wrong, but maybe Nolan is a bit of an idiot when it comes to science.
Please, Mr. Nolan, tell me which scientists make this claim?
I guess he read somewhere about infinity and how incredibly awesome and big and never-ending it is, and so eventually anything would be done by anybody or anything and so even monkeys would "eventually" write Shakespeare and and and....
Produce a movie called Interstellar with Matthew McConaughey.
In fact, maybe Chris Nolan is actually a monkey who crossed over from that obelisk in 2001, and got super smart and so a monkey already has produced a movie called Interstellar.
Damn, that is just so cool and so weird and it's like, that's never going to happen, man, no way.
So scientists had better figure out WHY that is not going to happen when they obviously really believe that it WILL happen (go, monkey, go!).
And to do that, they are going to have a cross a threshold, 'cause clearly science has hit its limit here. Just like with souls. Science can't explain souls, so I guess scientists had better cross over - maybe into a parallel universe -
Because really what could be cooler than parallel universes?
At Oracle OpenWorld this year Oracle announced the new Oracle Alta UI - a set of UI guidelines that will help you create better looking and functioning applications. We use these guidelines to build all our modern cloud based applications and products - and you can use it too today if you are on JDeveloper 12.1.3.
The Alta UI site is at http://bit.ly/oraclealta
Take a look for example at one page from the master details pattern page:
You might be wondering how do I go about starting to create such an Alta page layout?
Below is a quick video that shows you how to build such a page from scratch.
A few things you'll see during the demo:
- Basic work with the panelGridLayout - for easier page structure
- Working with the new tablet first page template
- Enabling selection on a listView component
- Working with the circular status meter
- The new AFAppNavbarButton style class
- Hot-swap usage to reduce page re-runs
One point to raise about this video is that it focuses more on getting the layout and look rather then the Alta way of designing an application flow and content. In a more complete Alta mind-set you'll also figure out things like fields that probably don't need to be shown (such as the employee_id), you'll think more about "why is the user on this page and what will he want to do here?" which might mean you'll add things like a way to see all the employees in a department in a hierarchy viewer rather than a form that scroll a record at a time. There are more things you can do to this page to get even better functionality, but on those in future blog entries...

I see a lot of companies using Microsoft Sharepoint as portal for their intranet. For many people it’s the first place they go to when they start their day. But to do their job they make also use of other applications, some which are build in Oracle Application Express (APEX). This presentation will show the different options you have to integrate both worlds of Sharepoint and APEX.
The integration can be both ways;
- in Sharepoint you get data or screens from APEX
- in APEX you want to use data (or a screen) maintained and coming from Sharepoint.
In the next weeks I'll add some more detailed blog posts, things I told during the presentation... for example how to setup your own MS Sharepoint environment.
I previously wrote that I peeped the idea about showing the session information in terminal title from Timur Akhmadeev’s screenshots, and Timur wrote:

Colored prompt is the one of many features of rlwrap.
You can always download latest version here: http://github.com/xtender/xt_scripts/blob/master/dynamic_sampling_used_for.sql
Current source code:

ps. Or if you want to find queries that used dynamic sampling, you can use query like that:
select s.* from v$sql s where s.sql_id in (select p.sql_id from v$sql_plan p where p.id=1 and p.other_xml like '%dynamic_sampling%' )
