Java, JEE, OAS and WebLogic Server
Oracle Java and the application server
One of the perhaps somewhat counterintuitive challenges with at least the initial stages of adopting Fusion Middleware is the fact that there is too little work in terms of administration.
On the one hand, Fusion Middleware administration entails quite a bit, starting with WebLogic Server
and typically extending to one or more FMW components:
all of which the administrator – or rather the administration team – needs to deal to with. Typically even around the clock to ensure the availability required by the business.
On the other hand, the actual workload for FMW administration for a small number of applications, services and processes does not justify a dedicated resource. This proves a serious problem for many organizations: 24/7 availability requires 3 FTE while the effort is on average less 0.5 FTE.
Organizations can adopt several strategies to address this challenge, as is illustrated in the next picture.
Tuesday May 15th, Nieuwegein – The Netherlands: During an intense day and evening, close to 120 Forms developers and architects gathered for discussions, explorations and exchange of experience around the use of Oracle Forms and more importantly: the future of the current Forms applications, Forms-using organizations and Forms developers. Various scenarios, approaches and tools and technology stacks were discussed, hybrid landscapes sketched and pros and cons evaluated.
An interesting line up of international experts on Forms had joined their collective forces and minds to present the most complete overview of the Future of Forms available anywhere in the world today. From relatively new and specialized solutions such as OraPlayer and Yo!Forms to more proven (OraFormsFaces) and mature, architecturally driven future scenarios from PITSS and Oracle Consulting complemented with Forms modernization and integration stories as well as the official strategy from Oracle product management.
This article provides access to most presentations that were on offer during this day. Some other resources are listed as well.
Sporting a selection of the world’s best known speakers in the area of Oracle Forms and Forms modernization – on Tuesday 15th May AMIS will host an all day event around Forms, aimed at application architects and lead developers. During this event, we will discuss and demonstrate the most relevant options for moving Forms applications (and Forms developers) to the future. Registration for this event is free – the capacity is limited. See this link for the full program, the abstracts for all the presentations and the biographies of the speakers: http://www.amis.nl/theme/amis/uploadedFiles/PDF/Future%20of%20Forms%20EN%20DAG.pdf.
The all-star, mostly ACE(D) team consisting of Lonneke, Steven, Luc, Edwin, Ronald and Lucas did a very entertaining jam session with Fusion Middleware most of all day yesterday at the OBUG 2012 Connect Conference (Oracle Benelux User Group). The third performance of its kind – ODTUG 2011 and UKOUG 2011 in Long Beach, California (USA) and Birmingham (UK) being the preceding gigs – successfully realized an end-to-end business process implementation with ingredients such as ADF, JHeadstart, Human Task, BPEL, Mediator, AQ, Event Delivery Network, Technology Adapters, UMS for Emails en of course the database.
In front of a live audience, the challenge was outlined. The high level design introduced and the various components discussed. The left-hand screen (for the audience) displayed the business process and the work done to it in terms of design and implementation. The screen in the middle demonstrated the user interface development using ADF and the right hand screen played various roles, from service development to Enterprise Manager display, BPM worklist and Email client.
The members of the band played the following instruments: Steven on ADF and JHeadstart, Luc on ADF and ADF More >
Veel PL/SQL ontwikkelaars hebben (n)iets met Java. Aan de ene kant zien ze dat Java op veel plekken wordt gebruikt, binnen en buiten de Oracle technology stack. En dat kennis van Java af en toe best handig zou kunnen zijn – zeker als je als klassiek Oracle ontwikkelaar gebruik wil maken van moderne technologie en je misschien wel een doorstart in je carriere overweegt. Maar aan de andere kant is de drempel om echt met Java aan de slag te gaan enorm hoog. Die hele wereld van Java en Java ontwikkelaars hangt aan elkaar van oneindig veel acroniemen, eigenwijze nieuwkomers die van een database niets moeten hebben en die dreigende schaduw van de Object Orientatie. Veel PL/SQL ontwikkelaars hebben wel eens naar Java gekeken, maar lang niet allen is die eerste kennismaking heel goed bevallen.
Met deze achtergrond in gedachten organiseert AMIS op donderdag 5 april een evenement waar PL/SQL ontwikkelaars de kans krijgen om (opnieuw) met Java kennis te maken.
In an previous post I discussed the stop start automated mechanism already, but now I developed a procedure how to automatically startup a complete Oracle SOA Suite 11g after a reboot.
The following components which are involved are:
- Database Instance
- TNS Listener
- SOA Suite Managed server including soa-infra application
The following scripts are used:
- dbora : init service file to stop start the database and listenere during startup
- soa_rc: init service file to start WebLogic and the SOA Suite during startup
