Bitmap to vector

I found a nice page, where you can convert your bitmaps to vector graphics.
Take a look here.
Vectormagic can convert the following files:
Output: EPS, SVG, PNG

They have some very nice samples online.
Yes i know, there are some program you can buy to do this, but if you only use this feature rarely, than an online conversion is very helpful....

Oracle SOA Suite 11g: Documentation

Just a small posting for all, who want to start with 11g and do not find the documentation:
Take a look at this link
(But it is only for the SOA 11g technology preview)

This Technology Preview release of Oracle SOA Suite 11g showcases the support for the Service Component Architecture (SCA) standard in Oracle SOA Suite through the new composite assembly editor in JDeveloper as well as a unified service engine foundation for the full set of SOA Suite components.

Dec 27, 2007

A first look at BPEL & SOA with jdeveloper 11g

Jdeveloper 11g beta 3 is ready for download...
What is new? It is the first preview with included BPEL modeler.
I was told that 11g everthing is based on SCA (service component architecture).
This changes the design process for BPELs, because now you can add more than one BPEL process to a project. Here the first screenshots:

First you have to add a SOA project

Then you can choose several composites (emtpy, with BPEL, with HumanTask..)

Then you get a BPEL process like you know it from jdeveloper 10g:

The only changes are some graphic enhancements for the drag and drop..
Now to the composite view:

This shows the like SCA requires the structure of a composite with services, references and properties...

Now you can add another BPEL into this composite:

and the your composite looks like

Now you could model the relationship between the BPEL with drag and drop, but this is senseless for this example.
So i hope this was enough for a short impression to jdeveloper 11g ...

Update: Here a posting covering the production version of SOA Suite 11g!

UMPC: Belinea 1

Belinea announced its umpc 1. Is this a real competitor to the ASUS EEE?
But its price is 800 Euros... (ok this is not fair, because you get 1GB RAM and a 80 GB HDD).
Really cool is the following thing:

Perhaps it has some built-in enhancements like the iPhone or iPod touch (look here)
It is amazing that this 1 looks like the FIC CE260 (take a look at this blog entry).

Official Oracle Wiki: Helpful?!?

Oracle started some weeks ago their official wiki.
But is this wiki really helpful? Who should contribute to this web 2.0 thing?

For example read a blog entry about the OWB wiki pages (Oracle Warehouse Builder).

Wikis-- especially corporate wikis-- are a tricky business. On the one hand, users and corporate staff can share information and let the wisdom of crowds emerge. On the other hand, a company can pitch up a wiki, call that their support strategy, and in essence tell their customers "Our product documents and supports itself. Isn't Web 2.0 fun?"

If you look there you will find many threads, which should be in
Really helpful information? Not yet....

But web 2.0 applications need their time to find their scope. So let's wait or better contribute to make the wiki successful!

Partitioning & Transportable Tablespaces

Here an example how to use in an Oracle database partitioning together with transportable tablespaces:

Create Tablespaces

To create tablespaces, put the following lines into a file createTablespace.sql

CREATE SMALLFILE TABLESPACE "&1" DATAFILE '/opt/oracle/oradata/XYNADB/datafile/&1.dbf'

and start the script via sqlplus with sqlplus system/pwd @ createTablespace.sql TTS01.
It will create a tablespace named TTS01. Repeat this step with TTS00 and TTS02.

Create Table

To create a partitioned table enter the follwing lines:

create table parttest (
id number, name varchar2(40), payload varchar2(40))
partition by range (id)
(partition part00 values less than (100) tablespace tts00,
partition part01 values less than (1000) tablespace tts01,
partition part02 values less than (10000) tablespace tts02);

Insert Data

Now put into the table parttest any data you want (the id has to be lower than 10000).
Just to verify, that the partitioning is working, use the following command:

select * from parttest partition (part01);

Adding new Partitions

To add new partitions, you have to create a new tablespace (s. abouve) and then enter the following command:

alter table parttest add partition part03 values less than (20000) tablespace tts03;

Drop an old partition

To drop an old partition, use the follwing command:

alter table parttest drop partition part00;

But with issueing this command your data in this partition is gone and there is no rollback!

Anything new?

Now we have a table partitioned over several tablespaces. We can add partitions and drop them.
The advantage is, that performance is better than with one unpartitioned table because the optimizer uses the partitioning to get faster access to the data.
But if you could move the partitions without dropping them, that would be a real enhancement.
Here the commands how you can:

Moving the data

First you have to create a table with the same structure as your paritioned table (but without the partitions) on the same tablespace where your data resides, which you want to move.
After that you can exchange the data of your partitioned table with the data of the new table.

alter table parttest exchange partition part01 with table parttestnew;

After that you can drop the partition on the original table parttest without loosing your data, which is still there in the table parttestnew. And if you want to can move the partition with the transportable tablespace feature from Oracle to another instance…

At GIP these features are used in the Xyna Service Warehouse (take a look at my guest post there!).

Lego-MP3player: Cool!!

I found a nice article in the web. A MP3 player which looks like a lego brick.
Very nice!!

They say (look here):
The core unit houses an OLED screen, 4-way directional toggle, and 50GB of memory. Should you need more, just snap on another memory module. Wanna share music with friends? No problem - just connect two BLOCS together and get your sync on.

This sounds cool!
But: It is only a concept....

Recursive BPEL

I found a nice article about recursive BPEL.
At first sight you think: no problem... but as the article says
Here the deployment fails with an error that it is unable to validate the WSDL for the Partner Link. The issue here is that as part of the deployment process we are “over-writing” the old stub version of the process, with a new version.

I think for business processes you should not use recursive BPEL, but it's like working with EXCEL. After the first macros you start developing a flight simulator ;-)

Creating Webservice with JDeveloper 11g

I found a nice link with an online demo for creating a webservice top-down with jdeveloper 11g beta.
If you can spend some time, take a look here. (i think you will need an OTN account to view this demo.)

They have completely rewritten the WSDL editor. Here a screenshot of the new style:

Oracle says:
Improved WSDL editor
The WSDL editor has been improved to provide better layout handling, including collapsible columns and validation and error feedback in design and code views. Other features to improve the WSDL editor are:
* Fast track navigation to all files implementing a WSDL *
* Extensive drag and drop operations for typical use cases
* Extensive binding options including EJB and JMS
Full support for JAX-WS
The wizards and editing tools for services and client generation now support the new JAX-WS Java EE5 standard, providing a simpler programming model than JAX-RPC and using JAX-B 2.0 for its data binding. Both annotation driven and deployment descriptor options are available.

Very nice is the feature, that you can add message part via drag & drop from XSDs... I hope iAS 11g will be released soon...

2XK is over...

The second xyna conference (2XK) is over. On the gip web pages you can take a look at the
official press release and get an impression.
There were keynotes given from SUN (a very humourous lecture about Wonderland Inc. from M. Jeske about second life for business), CISCO, Fokus and Oracle. AND of course the keynote from the director of the GIP research institute B. Reifenhäuser.

Here a short summary from the official agenda:

Xyna Service Factory: The fractal Telco-factory as the answer to the challenging defiances within Telco industrialization

Network abstraction as integral building block for fractal factories: Cisco next generation device and network management

Project Wonderland Inc. (Sun Laboratories): Web 2.0 for Enterprise Environments

From MetaSolv to Oracle Communication Service Fulfillment Suite: Driving Service Delivery Innovation in Communications

New FOKUS Open SOA Telco Playground: Evolution of Telco Service Platforms in Face of Network Convergence and SOA Principles

There are the first photos (including the party) available...

After ASUS announced the EEE for 299$, FIC will lower their price for the UMPC CE260.

You can buy this with an extent module, which is placed onto the right corner of the display...
The following modules are available:

Calendar and Clock or Skype and Bluetooth Phone; Option: TV Tuner or GPS Module

But there is no built-in webcam ;-(

EEE or CE260? Both are available with LINUX!
Let's wait for the first tests...

Sun Virtualization

Hmmm.. now i am getting confused:
At the Oracle Open World has Jonathan Schwartz (SUN CEO) announced SUNs Virtualization solution.
So this week Oracle launched its OVM as well as SUN launches its SUN xVM.

Here are some statements from SUN:
Host Windows, Linux and Solaris guest operating systems
Built using technology from the Xen open source project as well as Sun's Logical Domains
High availability and scalability
Advanced CPU and memory handling capabilities

At this link you can read further details about the SUN solution.
There is a community site at

So let's start with xVM? or OVM? or stay at VMWare or M$.....
(I am waiting for IBM eVM or iVM?)

A long time ago (part 3)

6/2005: One of the big television stations in Germany (ZDF) published a note about using Xyna Experimentierplattform for Webmining.

You can read there some numbers about the data amount:
In november 2004 59 of 86 million page impressions were analyzed. Not bad...

Oracle Virtualization

Oracle is going to attack VMWare and Microsofts Virtual Server:
Oracle VM

Oracle says about its new product:
Oracle VM installs directly on server hardware and does not require a host operating system. Two systems with static IP addresses are needed to install Oracle VM; one to install Oracle VM Server and one to install Oracle VM Manager.

For hardware virtualized (unmodified) guest operating systems (for example Microsoft Windows), a CPU with hardware virtualization support is required. This includes some Intel Pentium D, Core, Core2 and Xeon models, and some AMD Athlon and Opteron models.

Oracle Enterprise Linux 4 and 5;
REL3, RHEL4 and RHEL5;
Windows 2003, Windows Server 2003 and Windows XP are supported on Hardware Virtualized (HV) capable hardware;

I think for Oracle Partners this is a very nice tool to test and run different Oracle products on one machine to reduce the hardware cost. Let's see if they will add support for SUSE, SLES, Debian and Solaris x86...

How to speed up your JDeveloper

It is everytime the same thing with IDEs. They do a good job, but they do it not as fast as your (x)emacs or (g)vim...
Now you can change it:
Take a look at Shay Shmeltzer's Blog.

Here are my favourites:
1. Get a better machine
4. Having delays switching back to JDeveloper from other applications?

Some more tips are at the
JHeadstart Blog.

So move on and write your sources!!!

Oracle Magazine: Xyna, GIP & Oracle...

Take a look at Oracle magazine lists my company as one out of three Oracle Certified Partners, which has announced a product based on 11g:

GIP will use Oracle Database 11g in Xyna Service Factory, GIP's integrated platform for the development, production, and lifecycle management of IP-based telecommunication services. Specifically, Oracle Database 11g is the basis for two elements of the Xyna Service Factory platform: Xyna Service Warehouse, a subscriber-centric active warehouse, and Xyna Intelligence, a subscriber touchpoint management system. GIP serves leading German and international companies in the telecommunications, information, media, and entertainment sectors.

Weinlese 2007

Die diesjährige Weinlese zeichnet sich vor allem durch die Menge der Ernte aus. Die Weinberge tragen begünstigt durch den nassen und mäßig warmen Sommer sehr volle Trauben, die leider nur von normaler Qualität sind.
Der prophezeite Spitzenjahrgang wird wohl nicht dieses Jahr zu ernten sein. Vielleicht verhilft der jetzt kommende Altweibersommer den noch reifenden Rebsorten z.B. Riesling noch zu einigen Höhenflügen...
Aber für die Rotweine ist es schon zu spät.

Oracle Security

This evening i googled a little bit, looked into some blogs and suddenly i thought about webservices and security... What about using SOAP with SSL?
The the first step should be to configure the Oracle HTTP Server with SSL.
This sounds very easy, so i took a look at the documentation. Brrr...

There was nothing useful. Only something like: "on the menu bar choose wallet manager"
BUT how can i choose this on the Linux or UNIX server?
After a long search i found this nice documentation.

I do not know, wether it is the right version and so on, but just the information that the cli is owm was enough...
Perhaps i will try it tomorrow evening or not, but now i know how to start and this is quite enough.

Oracle DB 11g: Native Webservices


i found a nice blog about the native webservice support of Oracle database 11g. It is quite amazing.
You just have to write the right PL/SQL package and after that you can access it via an URL (the example in the blog is: http://server:port/orawsv/SCOTT/EMPCOUNT?wsdl).
I think Oracle has added the Java standalone webservice stack from the Oracle Application Server into the database.
Very nice!

The never ending story is ending? (SCO vs. Linux/IBM

Just fresh from

Novell owns the UNIX and UnixWare Copyrights. This seems to be the end for SCO... No more license fees from other companies and the chances for the condemnation of IBM are vanishing.



view days ago some former members of the X1-collaboration met in a pub. We just talked about the old days of working at MAMI at the Institut für Kernphysik Mainz. Our tutor Prof. Dr. Backe is since a year emeritus and still joining collaborations with other groups and institutes.
Here you can find a list with all his students (diploma & phd) which worked in his X-ray group. I am sorry to say, that there is no such link for his "Amaritium-group". Most of his students left science but some have made their way on other institutes and universities....
