Routing around the WS-* vendor stacks (Loud Thinking)

This is a link to an intresting article, quotes includes:

"The gulf between Web Services™ and web services have been widening as of late. HTTP awareness is on the rise, atompub is shining a light for best-practice REST, and the complexity of the WS-* stack is reaching astronautical heights.>>A comment in to the post states: >>So SOAP feels more like the doorknob to the gates of hell. In itself, a doorknob is hardly evil. But once you turn... :)"

APPS: Finding Flexfields per table

This SQL gave me a nice report on Oracle Apps flexfields used in a set of tables:

select distinct
fdf.APPLICATION_TABLE_NAME,
fcu.APPLICATION_COLUMN_NAME,
fcu.descriptive_flex_context_code,
fcu.END_USER_COLUMN_NAME,
fcu.ENABLED_FLAG,fcu.REQUIRED_FLAG,fcu.DISPLAY_FLAG,fcu.DISPLAY_SIZE, fcu.FLEX_VALUE_SET_ID
,fvs.FLEX_VALUE_SET_NAME, fvs.DESCRIPTION VALUESETDESC, fvs.VALIDATION_TYPE
from APPLSYS.FND_DESCRIPTIVE_FLEXS fdf
left outer join APPLSYS.FND_DESCR_FLEX_COLUMN_USAGES fcu
on fdf.application_id = fcu.application_id
and fdf.descriptive_flexfield_name = fcu.descriptive_flexfield_name
left outer join APPLSYS.FND_FLEX_VALUE_SETS fvs
on fcu.FLEX_VALUE_SET_ID = fvs.FLEX_VALUE_SET_ID
where fdf.application_table_name in (....list_of_tables...)
order by 1,2,3

AOSD tools for SOA?

Aspect-oriented software development (AOSD) is a holistic approach to developing applications with tools (eg AspectJ, Spring AOP) that uses tools that help abstract concern that crosscuts between different domains/objects.

The definition of AOSD is as follows:

AOSD is an emerging paradigm that provides explicit abstractions for concerns that tend to crosscut over multiple system components and result in tangling in individual components. By representing crosscutting concerns or aspects as first-class abstractions, and by providing new composition techniques for combining aspects and components, the modularity of the system can be improved leading to a reduced complexity of the system and easier maintainability.

AOSD is mostly about single systems and SOA is about interaction between systems or enterprise architectures. But I still think that there are AOSD tools that can help when you design your enterprise systems.

One of this tools is presented in the book "Aspect-Oriented Software Development with Use-Cases" Ivar Jacobson and Pan-Wei NG gives us a AOSD extention to the well known and mature use-case-driven approach.

HowTo: Reinstall/Secure EM DBconsole in 10.2

This is the commands to drop and reinstall the EM DBconsole repository and setup TLS security to secure your "SYS" passwords on the network. (If you only want to secure, start at step 3.)

1. emca -deconfig dbcontrol db -repos drop
2. emca -config dbcontrol db -repos create
3. emctl stop dbconsole
5. emctl secure dbconsole
6. emctl start dbconsole

Note that the emca syntax has changed in 10.2. (In 10.1 the commands are emca -x and emca -r ... I think.)
