Red Samurai ADF Performance Audit Tool v 3.2 – Large Fetch and Full Scan Audit Optimizations

Red Samurai ADF Performance Audit tool was updated with new features. Current update v 3.2 is focused on improvements for Large Fetch issues auditing, additionally we are able to track Full Scans (when user is fetching all rows and row count exceeds a threshold).

There are two additional threshold parameters introduced - WAT (Wait Activation Time) and WFT (Wait Fetch Time). These two are used to track long activation and fetch times in more (more...)

ADF BC Reserved Mode for DB Connection Critical Applications

With this post I would like to explain how you can control ADF BC mode and switch from default managed to reserved mode and back. With default managed mode, there is no guarantee in ADF BC for DB connection to stay assigned for the user session. Why it is highly recommended to design your ADF application in such way to be compatible with default managed mode, there are exceptional scenarios when we want to guarantee (more...)

Better Control for ADF UI Shell Tab Closing Order

This is third post in the series about ADF UI Shell usability improvement, you can read previous one - ADF UI Shell Usability Improvement - Tab Contextual Menu. When you work with Web browser tabs, expected behaviour after closing the tab in the last position is the next tab available on the left side to be opened. However, this works differently in ADF UI Shell and could be improved. I will describe how.

Here you (more...)

ADF UI Shell Usability Improvement – Tab Contextual Menu

In my previous post - Improving ADF UI Shell - Tab Closing Icon Adjustment, I was describing how to implement ADF UI Shell tab closing icon to be located directly on the tab itself. Today I would like to share one more usability improvement - tab contextual menu. You could implement such functionality as - 'Close', 'Close All' and 'Close Others' with contextual menu invoked from the tab.

Sample application with ADF UI Shell (more...)

Improving ADF UI Shell – Tab Closing Icon Adjustment

Default tab closing icon in ADF UI Shell is located in the top right corner. Users are not really happy about this and there is a demand to have the same positioning as you can see in the Web browsers - directly on the tab. Tab placeholders are implemented in ADF UI Shell with af:navigationPane and af:commandNavigationItem components. Component af:navigationPane supports item removal, this means we can implement tab closing functionality directly in the tab. (more...)

Personalising ADF Query with MDS User Persistence

I bet you are familiar with ADF Query UI having many criteria items. This may look irritating to the users, as there are so many options to use for the search. I will describe alternative approach in this post, with MDS user persistence and personalisation involved. It might be more user friendly, to offer only few criteria items by default and allow to add other items through ADF Query advanced option, together with MDS user (more...)

Implementing Dynamic Date Type Formatting with ADF BC

You may have a requirement to apply different format for date type attributes, based on username, as for example. Different users, may use different date formats - in such case, formatting for date type attributes must be set dynamically. This can be achieved, using approach described in my previous post - Controlling ADF BC Mandatory Attribute Validation Conditionally. I would extend explained technique and apply it for date formatting.

Sample application for download - DynamicFormatADFApp. (more...)

Comparing ADF View Object and Row Fetch Execution Times

I bet one of the most common doubts ADF developer, or may be DB admin, has - why VO SQL executes slower than the one identical from SQL Plus? This is often the case, but there is nothing VO SQL to blame about. Usually VO SQL executes in almost same time, as it would execute in SQL Plus - but there is extra added time of row fetch. When ADF UI page is rendering, data (more...)

Red Samurai ADF Performance Audit Tool v 3.1 – Drill Down Analysis Improvements

We have new improvements in Red Samurai ADF Performance Audit tool. Update 3.1 is focused on new features in drill down reports for Slow Queries and Large Fetches.

Current day occurrences (in red) for Slow Queries are calculated per individual VO instance, along with latest occurrences (in yellow) and total occurrences. This helps to track outcome of performance fixes and understand if additional tuning is required for specific VO instance:

It is possible to (more...)

Case Insensitive Search in LOV – Effective and Generic

Search in LOV dialog window, by default is not case insensitive. You could define View Criteria for LOV VO with case insensitivity and select this criteria to be displayed in LOV dialog. You could do this for one or two, may be for ten LOV's - but I'm sure you are going to get tired pretty soon. Much more effective is to implement generic solution to convert LOV search criteria to be UPPER case automatically.


MDS Seeded Customization Approach with Empty External Project

Great feature in ADF - MDS Seeded customisations support. This is particularly useful for independent software vendors, who are developing their own products on top of ADF framework. With MDS Seeded customisation, maintenance for multiple customers becomes easier. We could create customisation, instead of changing original source code - this makes it easier to maintain a product. I would like to share one important hint, related to technical architecture for MDS Seeded customisations - this (more...)

Hide All Search Operators for ADF View Criteria Item

During this week work, I received interesting question from ADF developer - how to hide all operators for specific ADF View Criteria item. There is an option to go and hide different operators one by one, following API guide for JboCompOper. You could follow this approach, but there is one smarter way - to hide all operators at once. See below - how.

Sample application is available for download - This application implements (more...)

ADF 11g PS6 Table Pagination and Displaying Selected Row Issue – Solution

While ago, I had a blog post about new feature in ADF 11g PS6 ( - table pagination support. There is an issue, when we want to open specific row and display it automatically in the table - required table page for the selected row is not opened correctly. However, blog reader suggested a fix, received from Oracle Support. Blog reader was kind enough, to post a comment with suggested fix, you (more...)

Why v 3.0 release is smarter? Because it (more...)

Shortcut to Call Custom View Row Method from JSF Expression

There is a custom method in Generic View Row Implementation class and you need to invoke it from UI. What would you do? Most likely you would generate Java View Row Implementation class for the specific VO, publish custom method through the interface and later consume it through ADF bindings. This works, but there is a shortcut - especially well working for generic solutions.

Sample application -, implements a table with row (more...)

How To Setup MDS Repository for Embedded WLS Instance

Recently I was enabling external MDS repository for ADF MDS Seeded Customizations, I was facing issues while testing such MDS repository with my local embedded WLS instance - running it directly from JDeveloper. I managed to find a solution at the end, so I would like to share it with you.

I was doing same thing as to configure MDS support for ADF Query Saved Search - defining persistence config in add-config.xml file. This (more...)

Why You Don’t Want to Code Validation in Before Commit

You should know by now - there are many things possible in ADF, but it doesn't mean every solution is right, even if it works. One example of such case - coding validation rules in beforeCommit method. This method is invoked after all changes are posted and ADF BC assumes data is valid, if we throw later validation error from beforeCommit - ADF BC state remains unchanged and changed data is not submitted again. There (more...)

Improving ADF UI Table CRUD Functionality with Auto Focus

Improving and tuning ADF applications performance, doesn't mean only ADF framework technical parameters tuning. Performance tuning could be applied to application UI behaviour. I will use ADF Faces table example in this post, by default when new row is inserted - focus for the new row column is not set, user needs to do one extra click to set focus and start entering data. There is a way to eliminate this extra click and set (more...)
