new SOA HA paper

Today I was pointed at a brand new SOA HA paper on OTN (thanks Simon. Although I didn’t give any direct input for the paper, it discusses the architecture I designed for my largest customer. I am very happy that Oracle recognizes that customers rely on active/active configurations.

Active Data Guard & Fusion Middleware Repositories.

Last year while working on a POC Rob den Braber noticed the following in Disaster Recovery for Oracle Elastic Cloud with Oracle ExaData Database Machine on page 13:

Currently, Oracle Fusion Middleware does not support configuring Oracle Active Data Guard for the database repositories that are a part of the Fusion Middleware topology. However, Active Data Guard can be configured if your custom applications are designed to leverage the technology.

Today this came up in a discussion with Simon Haslam , and he didn’t hear from this support issue before. So it seems that it is not that well know that Active Data Guard and Oracle Fusion Middleware is not a supported combination.

This makes this blog post a reminder from what is already in documentation (unless someone can comment and tell me that currently in the quote is not so currently anymore).

Hope this helps.

UPDATE:

While reading this brand new SOA HA paper I found this quote today:

The Oracle Active Data Guard Option available with Oracle Database 11g Enterprise Edition enables you to open a physical standby database for read-only access for reporting, for simple or complex queries, or sorting while Redo Apply continues to apply changes from the production database. Oracle Fusion Middleware SOA does not support Oracle Active Data Guard because the SOA components execute and update information regarding SOA composite instances in the database as soon as they are started.

3rd OUG Harmony Conference

On May 31th I will be speaking at the 3rd OUG Harmony Conference organized by Oracle User Group Finland. This conference will be held at Aulanko, Hämeenlinna Finland. My session will be about a core component that you need to understand to really manage Fusion Middleware: WebLogic’s NodeManager.

Handling WebLogic’s lifecycle is a core activity while managing Fusion Middleware. This is done mostly through an agent called NodeManager. This session is all about the subtleties and caveats of
NodeManager. Topics covered include:
– Role of the nodemanager in the middleware topology
– Nodemanager properties
– WebLogic startup sequence
– Starting and stopping through NodeManager
– Crash recovery
– Security and SSL

The agenda looks great and early bird registration is still open (till April 30th). So if you plan to go, now would be a good time to register

OOW 2011, the warm-up starts

Seems people start plugging their sessions for OOW 2011, so just to make sure I’m not facing an empty room here goes: This year (2011) I will be presenting on Oracle Open World together with my friend Simon Haslam. If you happen to be at OOW and fancy fusion middleware infrastructure, please come and join Simon on Monday 2 PM in Moscone South.

Title:		Deployment Patterns for Oracle Fusion Middleware 11g
Time		Monday, 02:00 PM, Moscone South – 310
Length		1 Hour
Abstract:		Oracle Fusion Middleware 11g is a comprehensive software suite that can be installed in a wide range of different topologies. In this session, an Oracle ACE Director and an Oracle ACE combine their real-world experience in a range of organizations (including supermarkets, government departments, and banks) to explain the decisions you have to make in designing a middleware infrastructure.The presentation covers Oracle WebLogic Server, supporting infrastructure such as Oracle Internet Directory, and layered products such as Oracle SOA Suite. Topics include domain planning, clustering options, handling virtualization, patching strategy, and promoting software from test to production.

Usefull utility for end of the road SR’s

I just recieved a usefull utility from Simon for end of the road SR’s

You can guess my state of mind now 🙂

Blogger meetup at OOW 2010

This one goes out to all bloggers out there that will visit OOW 2010.

Alex is organizing a blogger meetup (again). If you happen to be at OOW 2010 and you have feel like meeting some exceptional cool people (see the pythian website to find out who’s coming), please make a RVSP at the pythian website and join us at Jillian’s.

Fusion Middleware 11.1.1.3.0

The documentation for Fusion Middleware 11.1.1.3.0 is out. Now all I’m waiting for is downloadable versions of the software (including OSB!)

I just found the software on edelivery. It seems that only 32-bit software is on there now, but hopefully that will change soon.

OEM Grid Control 11.1 availlable for Linux

Rob Zoeteweij just made an interesting post, announcing OEM 11R1. He’s been on the spot quiet frequently lately. I wonder if Mr. Bulloch’s visit had anything to do with his accuracy 😉 ?

New paper at Method-R

Cary Millsap announced that he published a new paper called “Thinking clearly about performance”. I am not that much of a “plugger”, but I really really advise everyone that has to work with Oracle to read the paper. (an no, I’m not sucking up). Especially the qualification of performance as a feature is an interesting insight which I most likely will reproduce to some people.

Thanks Cary!

startup scripts

Every now and then there’s another discussion about how to create startup scripts for a database. Frits Hoogland just made an interesting post, somehow I get the feeling this information is new for most people. Being brought up with Linux instead of an old unix starts getting more and more useful 😉
