Apex EA2 update

To see the new style Plugins use this link to the Plugins Application provided by Patrick Wolf:

Plugins Application

I've managed to copy the syntax used in some of these plugins to update those on my Online Store demo.

I've still need to upload some images and it looks like (more...)

Apex EA2 is now available

The good news is that it appears that applications exported from Early Adopter Phase 1 import ok in the new EA2.

The bad news is that plugins have had a bit of an overhaul. It looks like the PL/SQL code used to construct a plugin now uses functions rather than (more...)

Application Express 4.0 Early Adopter Phase II (EA2) Available

The Application Express 4.0 Early Adopter Phase II (EA2) is now available. Like EA1, this instance is running on Amazon EC2. The beauty of Amazon's elastic IP feature is that we could work on the EA2 instance and get it completely ready, then associate the elastic IP with the (more...)

ruby-plsql 0.4.2 – better support for object types and types in packages

I just released ruby-plsql version 0.4.2 which mainly adds support for more PL/SQL procedure parameter types. See change history file for more detailed list of changes.

Object types and object methods

Now you can use ruby-plsql to construct PL/SQL objects and call methods on these object. For example, if you have the following type defined:

CREATE OR REPLACE TYPE t_address AS OBJECT (
  street    VARCHAR2(50),
  city      VARCHAR2(50),
  country   VARCHAR2(50),
  CONSTRUCTOR FUNCTION t_address(p_full_address VARCHAR2)
    RETURN SELF AS RESULT,
  MEMBER FUNCTION display_address(p_separator VARCHAR2  (more...)

Yet Another APEX Blogger.

I would just like to welcome a former colleague and good friend, Brian Spendolini, to the APEX blogging community and I look to interesting and informative posts for him in the weeks and months to come.

Excel and Oracle OLAP – Reporting No-Agg Measures

Uncategorized
| Feb 23, 2010
I've run into this a few times recently, so here's a quick tip related to using Excel with Oracle OLAP (via the Simba MDX Provider for Oracle OLAP, of course).

Here's a situation that's been reported as a bug, but you really just need to know the right Excel Pivot Table option to choose. Consider a cube that has measures that do not aggregate but is dimensioned by a dimension with a hierarchy. In this case, there is a cube with a Store dimension with levels Store > Store Type > All Stores. The stores are located in different countries (more...)

Row Migration and Row Movement

The Oracle database knows three distinct processes that are easily mixed up: Row Chaining, Row Migration and Row Movement.

Luckily all three are well described in excellent articles: The Secrets of Oracle Row Chaining and Migration and Row Movement in Oracle.

For the impatient, I provide some very short definitions:

Row Chaining
Distribution of a single table row across multiple data blocks.
Row Migration
Relocation of an entire table row to a new place, without updating the indexes.
Row Movement
Relocation of an entire table row to a new place and updating the indexes.

This article was inspired by the (more...)

Static Region Id’s and Ajax Fun

More Online Store demo shenanigans for you. A bit dry this one I'm afraid.

A couple of days back I decided to export/import my Online Store demo, and whilst viewing the new imported version of the application found it to be completely kaput.  It didn't take long to realise (more...)

Cool but unknown RMAN feature

Unknown to me anyway until just this week.

Some time ago I read a post about RMAN on Oracle-L that detailed what seemed like a very good idea.

The poster's RMAN scripts were written so that the only connection while making backups was a local one using the control file only for the RMAN repository.
rman target sys/manager nocatalog

After the backups were made, a connection was made to the RMAN catalog and a SYNC command was issued.

The reason for this was that if the catalog was unavailable for some reason, the backups would still succeed, which would not (more...)

We are planning to move our 11gR1 database to 11gR2 soon once minimum patch requirement for OS level met. Will keep you posted.

Happy Troubleshooting !!!

How-to: Archiving Oracle FMW B2B 11g run-time data using data pumps

In Oracle Fusion Middleware B2B 11g enhanced procedures are introduced to archive and/or purge the B2B 11g run-time data.

The procedures that take care of archiving/purging live in the SOAINFRA database schema of your FMW 11g database repository:
  • B2B_ARCHIVE_PROCEDURE
  • B2B_EXPORT_JOB

The B2B_EXPORT_JOB procedure does the actual archiving and is invoked from the B2B_ARCHIVE_PROCEDURE procedure. The B2B_EXPORT_JOB procedure uses a data pump to archive the run-time data to a file on the file system.

Flashback logging only has a 2% performance decrease…or not.

Firstly apologies to both people who have previously read my blog, things have been a little hectic over the past 12 months working away from home in the Netherlands has taken its toll on my spare time, and weekends are to be spent either with the family or working, things have settled into a more stable pattern now so here goes..
