  • Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen
    "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book," says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?"
  • Process Oracle OER Events using a simple Web Service | Bob Webster
    Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types."
  • Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients | Andre Correa
    "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen.

  • Oracle 11gR2 RAC on Software Defined Network (SDN) | Gilbert Stan
    "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc."

    H/T to Oracle ACE Director Tim Hall for the recommendation.
  • ServerSent-Events on WebLogic Server | Steve Buttons
    "The HTML5 ServerSent-Event model provides a mechanism to allow browser clients to establish a uni-directional communication path to a server, where the server is then able to push messages to the browser at any point in time," explains Steve "Buttso" Buttons.
  • Focus on Architects and Architecture
    This handy guide for sessions and other activities at Oracle OpenWorld 2012 focuses on IT architecture in all its many facets and permutations.

"We will use VMware as our virtualization platform and use CentOS as the operating system," says van Wijk. "We end the post by showing how the operating system can be tuned when running a Java process such as WebLogic Server."

"So if you try to use Java or Expression Language to get the logged in user you will only find anonymous and none of the BPM Roles you will be expecting. So what to do?"

  3. Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld
    "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions—inside and outside the enterprise."
  4. Adding a runtime picker to a taskflow parameter in WebCenter | Yannick Ongena

  6. Setting up a local Yum Server using the Exalogic ZFS Storage Appliance | Donald
    A concise technical post from the man named Donald.
  7. What's New in Oracle VM VirtualBox 4.2? | The Fat Bloke Sings
    "One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's," says The Fat Bloke. "Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends." The new VirtualBox release, a year in the making, addresses the needs of these users, he explains.
  8. Configuring Oracle Business Intelligence 11g MDS XML Source Control Management with Git Version Control | Christian Screen
