Migration to Oracle Weblogic 12c and Clustering

noreply@blogger.com (Anonymous) — Tue, 12 Jul 2016 13:59:00 +0000

Weblogic 12c has been a great revision to the oracle fusion middleware product application server and now we have had a chance to work with this can see just how good it really is.

Having covered a few migrations to 12c now can say the clustering across multiple nodes works really well having extensively performance tested this and compared with some older oracle application server / container based products it is a massive improvement. 12c supports java 8 and 64 bit server processing. And works nicely on oracle solaris 10 on sparc CPU's as well as solaris zones which is oracles version of unix containerisation for the os. Version 12.1.1 had many bugs which weve had the pleasure of helped Oracle identify many bugfixes 12.1.2 an later are much more stable and usable. Overall it is a massive improvement over 11g. For clustering 2 through to 16 nodes it runs great.

Oracle continue with there suite of integrations of there other products the list now is extensive along with the aquisitions these include products from ATG, Agile PLM, Endeca, HCM and E-Business suite.

Virtualisation and Application Servers

noreply@blogger.com (Anonymous) — Sun, 12 Jan 2014 16:14:00 +0000

Now more an more everyone is trinyg to cut cost, become more efficient and get more done with less money.And what better way to do this than virtualise, it used to be the way that virtual machines , which by the way are noot a new idea (IBM came up with the concept many years ago for mainframes).
Virtual Machines were slow fragile and time consuming to set up , now vmware has matured to be the industry leader at time of writing with products like vmware fusion , vmware workstation , vmware esx server and vmwre player, it is now a brighter pleasant experience to work with for virtualising and cloning multiple servers , the phrase P 2 V you may hear repeatedly this means physical to virtual , they offer a tool that basically virtualises your real machine into a VM, and very good it is too.

Some of these technologies you can use for free, and now the marketplace has grown up there are many competitor products such as virtualcenter and Oracle VM Virtualbox, KVM , Hyper-V

Performance tuning old JDK life past end of life?

noreply@blogger.com (Anonymous) — Wed, 14 Aug 2013 20:15:00 +0000

Performance tuning a old system 32 bit that is past end of life and still going on a old java JDK that is too cost prohibitive to re-code and too old to run a probe on (inconpatible) , canit be done?

This was the issue I had to work on in a recent project that I took on , and amazingly there is life in taking a old system and 'enhancing it'. Contact me if this is something that you are at as my last project the client was really stuck with no way in a seemingly impossible scenario, but we showed them the light and they are much better off for the experience.

We can help with :
Getting your old system upgraded to take full advantage of better more powerful hardware.
Tweaking & tuning to get every last bit of capacity out of it
Design to ensure it is best strucutred to suit your requirementso
The path toward enhancement in a cost effective way.

Especially with old java 1.1, 1.2 and 1.3 an 1.4 JDKs
Especially with 32 bit architectures
Especially with performance bound systems

Weblogic lives on

Weblogic 12c is finally here!!! Just in time for 2012

noreply@blogger.com (Anonymous) — Thu, 19 Jan 2012 22:54:00 +0000

Yes this launched on december 1st 2012

http://blogs.oracle.com/cloudappfoundation/entry/brand_new_oracle_weblogic_12c1

And for those of you that have not yet been able to get your hands on it here are some useful nuggets of info:

http://technology.amis.nl/blog/14436/weblogic-12c-questions-and-answers

The big WOW factor with this release of Weblogic is that it will fully support JEE ( java 6 )
And if you have been following the presentations by oracle over the last few months you will notice they are
stating it will have the following major benefits:

Optimisation of source code and Integration with the Hardware stack making it run - MUCH FASTER

Benefits of the Fusion product set and integration with THE CLOUD

Improved reliability, scalability and productivity.

http://blogs.oracle.com/cloudappfoundation/entry/oracle_weblogic_server_12c_launch

Now I have had 20 minutes first looks around this and it feels like classic weblogic from the backend but more refined and grown up from the front end user interfaces.

I do not see rapid adoption but rather a slow start move towards this version gaining pace as time gets more toward end of 2012 as there will be many out there running J2EE application servers on very old JDK's that over time will realise the benefits to moving to Java 6 JEE especially when they start to see others getting good results and more familier with the 1.6 JDK only then will they start to really leverage the BIG benefits it brings.

Weblogic Server Lives on in many forms...

noreply@blogger.com (Anonymous) — Tue, 20 Jul 2010 22:27:00 +0000

Despite us being in a financial crisis, many older versions of weblogic continue to run successfully in many companies.

These include bea weblogic server 8.1 sp6
bea weblogic server 7.0
bea weblogic server 6.0
bea weblogic server 5.1

Old software often has end of life associated with it but many people continue to run older versions out of lifetime.
Knowing its nuances and after running with it for a teething period, this tends to work well once the application is mature
and stable and there is little to no reason or budget to move over to a newer version.

Newer versions can bring more features but at the same time more complexity , why re-invent the wheel when a older
simpler system works for your requirement.

Of course if you want to be on leading edge then you will go for oracle fusion middleware.
And if you want to be as near to leading edge but on a budget the choice is glassfish.

Cloud computing and weblogic....

noreply@blogger.com (Anonymous) — Mon, 17 May 2010 19:48:00 +0000

July 20, 2009 - This was the day that oracle's grid architecture and weblogic server harmoniously came together.

From Oracle's website:

http://www.oracle.com/us/corporate/press/021490

Oracle announced the release of Oracle® Coherence 3.5.

A component of Oracle Fusion Middleware, Oracle Coherence 3.5

This new version introduces Coherence Guardian, a safeguard that automatically detects and corrects service disruptions.

Oracle Coherence 3.5 provides native integration with Oracle WebLogic Server and Oracle WebLogic Portal, dramatically boosting the performance and scalability of applications deployed on these products.

In addition, Oracle Coherence 3.5 also includes a significant performance boost in the Coherence*Web session management module.

I quote from oracle website :

"These new capabilities help organizations improve their online customer experience, simplify the management of large web deployments, and differentiate their Web presence for competitive advantage."

So if you have gotton your head round clusters and scalability this is really the final up-scale afterwards.

Really for big organisations or heavy use websites requiring the top end of resiliance and scalability.

For now recognise that oracle is investing heavily in this area and cloud computing is here to stay.

I will write more on this topic in a future post

Oracle Weblogic 11g - first looks

noreply@blogger.com (Anonymous) — Sat, 09 Jan 2010 15:28:00 +0000

Just had look at this wonderful piece of kit.

weblogic 11g oracle name oracle middleware is currently at weblogic version 10.3.1.0
and is made to be harmoniously SOA orientated, first looks show a new fresh looking admin console, and a whole load more features, however nothing in this version really jumps out from first impressions and is this really a minor revision to 10 rather than a whole new version?
Well by naming it 11g will bring more of a marketing and branding advantage than a technical one like the fantastic name there marketing dept has come up with ...only time will tell the value that 11g will really bring...I am looking forward to oracle weblogic 11g v2.

UK's Largest Payment Processing Company Migrates to Weblogic

noreply@blogger.com (Anonymous) — Mon, 29 Dec 2008 00:24:00 +0000

Voca ( BACS ), UK's largest payment runs Weblogic

Voca process money transactions they have built a successful system based on weblogic
and migrated from old IBM AIX & Tandem / Mainframe Systems (taking up masses of space in North West london) over to Newly Architected Web Infrastructure and 100% Java solution what is a increasingly complex business with tight SLA's and huge responsiblity
including meeting standards inposed by Bank of England, their system comprises:

BEA Weblogic 9.2

JDK 1.4 / J2EE 1.4

Spring

Hibernate

Oracle 10 RAC

Oracle AQS

Deliverables Successes :

80 Million + Transactions / Day

100% Data Integrity ( Never lost any data )

Power to handle 100 Million Transactions in under 4 Hours ( to meet tight SLA's)

The messaging of transactions utilised totally new solution of 'competing consumers' and overcome the challenge of existing BEA messaging by utilising Oracle AQS message Queing, Local Transactions now this is all part of BEA Weblogic since the merger with Oracle Corporation.

Weblogic Portal 10.2 (WLP 10.2)

noreply@blogger.com (Anonymous) — Tue, 23 Dec 2008 15:32:00 +0000

Has finally arrived and what a fantastic package it is,
Bea have adopted unifying open standards compatiblity with 10.2 and
can confidently say yes to web 2.0 and many of the technologies in
previous version.

Including Xtreme Progamming, Agile methods, Service Orientated
Architecture, compatibiliy with
Eclipse via Workspace Studio, JSF, Spring , Struts , WYSIWIG, and Web
Services for Remote Portlets (WSRP)
WSRP is a interesting one allowing .NET Apps to run well in WLP. Mashups
is something you will hear more of and this is
the ability to re-use something that is already published to a web site
or portal in your new portal but rather than having to re-create the wheel
you just adopt in your new portal using WYSIWIG and mashup feature.
SSO - single sign on although not new in WLP has matured in this
version to something rather more usable (rather than just a fudge in
together in previous versions), improved deployment mechanism (zero
downtime ) make this a must have version of WLP.

I am now taking on migration work to the new version and I recommend
users of previous versions to get in touch if this is something your
looking to move towards.

goodbye BEA.Com hello OTN

noreply@blogger.com (Anonymous) — Sun, 21 Dec 2008 22:08:00 +0000

As of 5 December 2008 bea.com website is no longer being updated,
instead for the latest weblogic info you will need to be a subscriber to
oracles Oracle Technology Network ( OTN ).
As you may well know, this is going to ruffle a few feathers in the
weblogic circle. However Oracle have had reign of BEA for over 6 months
and have slowly adopted the approach to integrating into their core.

Application Monitoring Roadmap

noreply@blogger.com (Anonymous) — Sat, 08 Mar 2008 00:42:00 +0000

Out of the box J2EE app servers (in our case weblogic) has some monitoring and fantastic logging mechanism however there is not much in the way of monitoring that can be used to really pinpoint what is happening with your applications and or your EJB's servlets database connections etc.

There are some things that can help you here these tools are:

Wily Introscope (as used by BEA internally) by Computer Associates
Quest Jprobe

There are some others out there but these are the main 2.

Other ways to monitor is to use JMX this is a purpose architected system inbuilt in J2EE model
that is effectivly a structure for writing a system to monitor your apps.

JMX is implemented using Mbeans

Load Balancing or Clustering?

noreply@blogger.com (Anonymous) — Sat, 08 Mar 2008 00:40:00 +0000

To Cluster or not to cluster that is the question?
Weblogic Server lends itself very well to clustering, all the components are available, all the specifications are there and it has had clustering capability long enough through the versions to make this a viable solution, questions is do you want to cluster?

Advantages are:

Resiliance no more single point of failure in the application tier

Session Replication, if a server goes down your session will carry on just by another server node in the cluster.

Disadvantages are:

Complexity - more complexity means more risk of it not working(down more to configuration or human error than the software)

Need more Server resources - more disk , more cpu , more network traffic etc...

Your applications will need to use the clustering services in the container and so they need to be coded to be made 'cluster aware'

Load Balancing is a much simpler setup to implement

Advantages

Quicker and easier to setup

No need to re-engineer your apps.
