This post covers Oracle Open World Insights, followed by a BPEL/BPMN comparison, and design discussion. This is an interesting topic to me, since very little has been published and the product direction was clearly shown at OOW. I have also seen the difficulties of BPMN round tripping, which leads me to believe BPMN 2.0 is going to be great for functional process models, but will enforce a rigid process architecture on the technical model, leaving developers with a process architecture that is difficult to work with.

ORA-00845 on Oracle 11g DB in a Virtual Machine (OVM)
If you run across this error when trying to start a database instance within a virtual machine, chances are that you may have reduced the allocated RAM to the VM. This is due to the automatic memory management module of Oracle DB 11g. One solution is the increase your memory allocation back. ORA-00845: MEMORY_TARGET not supported on this system Problem Description While creating a startup database using dbca the database creation GUI gives error message in a pop up window, ORA-00845: MEMORY_TARGET not supported on this system from where you can ignore the error message. The similar scenario also occur … Read More
Oracle OpenWorld OOW 2010 – Middleware
As has become tradition, I will be attending Oracle OpenWorld again this year joined by a few other M&S team members focused on Oracle Fusion Middleware. Let us know if you will be around and want to meet up. The most solid agenda items I have are the authors’ seminar for a new WebCenter 11g book we are releasing (more on that to come), a few of the SOA, BPM, Governance, and Enterprise 2.0 events with Product Management teams, and, of course, the concert.
Oracle DBMS_SCHEDULER vs DBMS_JOB (Create, Run, Monitor, Remove)
DBMS_SCHEDULER is a newer, more complex job scheduling engine released in 10g, intended to replace DBMS_JOB going forward. DBMS_JOB, the older job scheduler, as of now is still available for quick and easy DB based job scheduling.
Job scheduling comprises the core of the functionality of DBMS_SCHUDULER, however here are some additional benefits available to DBMS_SCHEDULER:
- Logging of job runs (job history)
- Simple but powerful scheduling syntax (similar to but more powerful than cron syntax)
- Running of jobs outside of the database on the operating system (see below)
- Resource management between different classes of jobs
- Use of job arguments including passing of objects into stored procedures
- Privilege-based security model for jobs
- Naming of jobs and comments in jobs
- Stored, reusable schedules
Oracle Enterprise Manager (EM) 11g – Adobe AIR Desktop Widgets
I like seeing Oracle leverage non-Oracle technology, like Adobe Flex and AIR. I hope that trend continues for Oracle…while Microsoft goes off to build things like Silverlight and Apple simply decides to avoid support for Flash altogether on their iPhone and iPad devices. I haven’t played with these widgets myself yet, but I do like the idea and sure we will be leveraging them.

WebLogic and WebCenter SSO with IIS – Windows Native Authentication (WNA), SPNEGO using Active Directory (AD)
Setting up Windows Native Authentication (with Kerberos) Single Sign-On (SSO) within WebLogic can be tricky. One way to accomplish this is to use IIS to front-end the WebLogic cluster. You need to use an IISIdentityAsserter in this scenario. Using an Identity Asserter based on HTTP headers has security implications and it’s important to ensure the communications are locked down between the IIS front-end to the WebLogic cluster. I don’t have much time to type more about this, but was excited about some recent work and wanted to get a quick post up in reference to this.
