Last few days I was busy with installating R 12 (12.1.1) on VMware. It was very hectic but learning experience for me. In my previous post I have put screens for installing VMware on Windows 7 and Oracle Enterprise linux over and above VM. Here are the explaination of all figures.
Fig 1 : This is the first screen which will see after you click on installation file for VMware 2.0.1, which I downloaded from http://www.vmware.com/download/server.

Oracle PL/SQL unit testing with Ruby

Current PL/SQL unit testing options

Unit testing and TDD (test driven development) practices are nowadays one of the key software development practices. It is especially important if you are doing agile software development in small iterations where you need to automate unit testing as much as possible, as you cannot do manual regression testing of all existing and new functionality at the end of each iteration.

In some languages (like Java, Ruby, Python, C# etc.) there is quite good tools and frameworks support for unit testing and as a result there is quite high testing culture among top (more...)

How to change BPEL 11g preference values during deployment time

How you can set BPEL preferences in 11g during design time in JDeveloper and run-time in the EM console is described here (for the latter look in the comments for a reference).

Sometimes it is useful to change the preference values during deployment time, because preferences hold environment specific values. Actually, this is pretty easy by using composite deployment configuration plan(s). One for each target environment.

Right-click on the composite file and generate a deployment (more...)

Vive la diference!

And I'm not talking about the one between Mars and Venus!Some of the regular readers will no doubt recall my comments regarding the MOS introduction.Yes, dang right they were strong words! We pay Oracle YEARLY in excess of 6 figures in maintenance fees.A large chunk of which is for our access to Metalink/MOS/whatever.The last thing I need when that is unusable for a long period is some idiot

More Oracle data types supported by ruby-plsql gem

I have just released ruby-plsql gem version 0.4.0 which provides many new features. You can read about initial versions of ruby-plsql in previous blog posts.

Oracle complex data type support

Initial versions of ruby-plsql supported just simple Oracle types like NUMBER, VARCHAR2, DATE, TIMESTAMP, CLOB, BLOB as PL/SQL procedure parameters. Now support for many more complex data types is added. See examples below how to call PL/SQL procedures with these complex data types.

PL/SQL Record

Let’s assume you have PL/SQL procedure with PL/SQL record type parameter (which most (more...)

Convert Oracle Date Format to Excel Date Format

MS Excel uses a numeric format, called Serial Date format, when storing and dealing with dates and times.   Serial date is calculated by taking a given date and determining the number of days that have passed since that date and 01-Jan-1900 (actually 00-Jan1900, but that’s a story for another time).  Why is this important to an Oracle developer?  If you are using a tool such as the ExcelDocumentType to generate an Excel document with PL/SQL and you are trying to apply an Excel style to an Oracle Date data type … it will not work.  The (more...)

Oracle Fusion Middleware 11g end-to-end tracking using the ECID

In a previous posting I described how you could use composite sensors to enable end-to-end tracking for messages that move through the Oracle Fusion Middleware SCA engine and the B2B engine.

Today, I discovered that you can also use ECID for end-to-end tracking. The B2B application message contains all the tracking properties that are originated from the SCA composite that submitted the message to the B2B engine. With the B2B Report console you are able (more...)

How to configure an ebXML communication in Oracle Fusion Middleware B2B 11g

Oracle Fusion Middleware (OFM) B2B 11g supports many business document and messaging standards. ebXML (Electronic Business using Extensible Markup Language is a B2B messaging standard that is also supported by OFM B2B 11g. Shortly described ebXML enables XML messaging over the Electronic Business messaging Service (basically a SOAP extension), abbreviated as ebMS.

This posting describes how to set-up ebXML messaging using two local OFM B2B 11g (PS1) domains. For simplicity, I will extend my previous (more...)

Production Upgrade complete… hack obsolete!

It had to happen. I've moved away from very retro hardware requirements and a couple of hacks to something much simpler, and more applicable to "modern" computers ie. those with USB ;-)

No. 8 wire solution no longer needed ... luckily the wires aren't that thick :-)

Old:

New:

Bonus points to Readers that guess the application of this stuff!

Catch ya!

The other day someone asked me how to do we collect a refund from an employee to whom we have made an advance payment (prepayment). There are a couple of approaches that can be used. The same approach applies to refund from suppliers as well.
Approach 1: Invoice to retire the prepayment and then Debit Memo for refund.
Step1: Create a standard invoice and apply the remaining amount of prepayment to it.
Step2: Then enter a debit memo and pay it with a Refund payment in the Payments window.The result will be that the outstanding prepayment / advance (more...)
