- Retrieving WebLogic Server Name and Port in ADF Application. It could come handy to know how to get WebLogic server name and port in ADF application. Particularly this could be useful, when running ADF application in the cluster and there is a requirement to track WebLogic node with application session instance running. Usually it is not enough to get server host, as cluster node is accessed through load balancer and server IP is different, not the one visible in HTTP session.

- 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 will be related to the way how MDS Seeded customisations are organised and maintained. By default, you would create MDS Seeded customisation files in the original application, however this is not very clean approach. There is a way to create and keep all MDS Seeded customisation files in empty external application. I will describe in the post, how this can be achieved with a few easy steps.

- 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.

- Optimizing Long Running ADF Operations with Parallel WebLogic Time Manager Execution. This blog title sounds a bit fancy - isn't it? :) I was looking how to optimize long running operation execution and separate it from ADF context (so, ADF application will remain responsive). Additional requirement - the same long running operation might need to be invoked multiple times, based on execution result and other parameters. Here I would like to share solution with you today - solution is pretty cool, it involves WebLogic time scheduling for delayed long running series of ADF requests execution initialized from ADF session context.

- Few Hints about ADF 11g Web Deployment Profiles. While doing different ADF 11g projects reviews, I frequently encounter situation when ADF deployment package size is multiplied at least by two, comparing to what it should be. Usually this happens because improper application libraries packaging - source code is duplicated during packaging into multiple identical libraries later included into EAR deployment distribution package. Today I will describe few hints related to this topic.

- Advanced MDS Management for Oracle ADF 11g and Oracle WebCenter 11g Applications. MDS functionality in Oracle Fusion 11g is really cool, and it makes Oracle ADF very competitive comparing to other development frameworks. You can read about personalization and customization support - Applying Personalization and Customization in Oracle ADF 11g and Oracle WebCenter 11g. However, most of the customers are asking, how they can manage MDS metadata repository effectively. In the current release of Oracle Fusion 11g, we don't have MDS metadata repository browser, its not easy to track who and when did MDS personalizations or customizations. Because of lack of MDS browser/editor, people sometimes can see a risk to implement systems with MDS functionality, no one wants to have black box as part of IT infrastructure. I have provided this feedback to Oracle Product Managers, I'm sure in the future we will have MDS browser/editor tool. I will explain, what functionality we can use today, for MDS repository management.

- Managing ADF Security Using Oracle Enterprise Manager 11g. Recently I had a long meeting on customer side, to discuss and describe various ADF Security management strategies in production environment. Good news - at the end, everyone left this meeting happy and with correct understanding of benefits given by ADF Security. I will describe how you can manage Application and Enterprise security roles, as well as Permissions, after ADF application deployment on production WebLogic server.

- Deploying ADF Applications as Shared Libraries on WLS. Today I have new post from Integration series. Most of the ADF applications are developed using multiple ADF Task Flows packaged into different ADF libraries. When we consume ADF libraries, by default these libraries are included into resulting EAR deployment package. In most of the cases it works well, however on large production deployments, customers ask to externalize and exclude ADF libraries from main site deployment package. This allows to redeploy shared ADF libraries without main site redeployment. Multiple applications can consume shared libraries, without packaging them into each EAR package. There is George Maggessy blog post about ADF Task Flows and Shared libraries on WLS - post.

- Oracle WebTier 11g Configuration for ADF 11g Applications. Oracle Web Tier description - Oracle Web Tier includes components that interact with end users at the outer most tier of application grid infrastructure typically through HTTP requests and responses. Oracle Web Tier hosts web pages (static and dynamic), provides security and high performance along with built-in clustering, load balancing and failover features. It sounds like this Oracle Fusion Middleware product can improve ADF applications performance, especially on public internet. Typically ADF applications are coming with significant amount of Java Script and skin images - Rich Client, so let's see how Oracle Web Tier components (HTTP Server and WebCache) can help us.

- Optimizing Oracle ADF Application Pool. If you was reading my previous post - Monitoring Data Source Connection Leaks, you got clear idea how you can monitor data source connection pool usage by Oracle ADF application. Basically speaking, Oracle ADF application works with two pools - Application and Database. First pool allows to optimize application work on middle tier, while second pool cares about database connections. Today I will describe how you can control JNDI data source connection pool.

- Manual Oracle ADF Application Deployment on WLS with JDBC DataSource. In Oracle Fusion 11g R1 we can deploy Oracle ADF applications on Oracle WebLogic server directly from JDeveloper 11g - and it works perfectly. However, sometimes we need to deploy EAR file manually from WLS console. If you'll deploy your application to EAR file and later will try to deploy on WebLogic server through console, you will get deployment error related to database connection: No credential mapper entry found for password indirection. I have solved deployment error after reading Steve Muench blog post.

- Oracle ADF BC Deployment and Imported Libraries. Last year July, I was writing about ADF BC sharing through JAR libraries across entire application. It works the same in current JDeveloper 11g release, however during deployment on standalone WebLogic server I have noticed some problems. When application with imported ADF BC libraries was deployed, shared ADF BC components were not found on the classpath and page wasn't loaded. For more info about importing shared ADF BC libraries you can find in my previous post - Import Functionality in Oracle ADF BC.

Spanish Summary:En anteriores post, se mostró como hacer uso de una libreria ADF BC en otros proyectos usando Jdeveloper 10g. Sin embargo, en la actual versión de la herramienta 11g existen algunos inconvenientes que son resueltos en el siguiente post.
- Practical ADF Security Deployment on WebLogic Server. In this post I will describe step-by-step how to deploy your Web application with ADF Security enabled on standalone WebLogic server. You can download my sample application, I was deploying and testing. ADF BC Application Module is configured to use JDBC DataSource - java:comp/env/jdbc/HrDS, dont forget to define jdbc/HrDS JNDI on your server, before running application.
