Oracle EBS Customization and Extension – OAF vs ADF vs APEX vs Forms

Andries Hanekom:

The E-Business Suite Technology Group recently released a whitepaper: Extending E-Business Suite 12.1.3 using Oracle Application Express. In summary, “This new whitepaper outlines how to extend Oracle E-Business Suite 12.1.3 (and higher) functionality using Oracle Application Express. Recommended architecture and security considerations are discussed in detail.” For some time now EBS customers have used APEX to extend EBS, with the release of this whitepaper the EBS Tech group has acknowledged the growing use of APEX to extend EBS and have provide recommendations and guidelines for integration.

What’s this all about some might ask, is Oracle moving to incorporate APEX as part of the standard EBS tech stack? What about OAF? Isn’t Fusion Applications build on ADF, so what’s up? Well when it comes to Oracle EBS extension and customization, OAF is till the top dog, the E-Business Suite Technology Group continues to recommend OAF for EBS extensions.

Oracle DB 11g Password Expiry Gotcha

Eddie Awad — Mon, 11 Apr 2011 16:26:15 +0000

Jeff Hunter:

Something I discovered recently is that the DEFAULT profile for Oracle 11g sets the PASSWORD_LIFE_TIME to 180 instead of UNLIMTED by default. Applications will encounter an “ORA-28002: the password will expire within X days” error message if you keep the default value.

To change the PASSWORD_LIFE_TIME, you:
ALTER PROFILE default LIMIT password_life_time UNLIMITED;

Neat Oracle Database 11g Release 2 Feature: Preprocessing External Tables

Arup Nanda:

External tables enable users to access data in text files, immediately eliminating the need to load input text files to intermediate tables for processing—saving both time and storage space. Now, with Oracle Database 11g Release 2, intermediate processing of any kind—such as decompression of compressed input files—is eliminated, further saving time and storage, not to mention a change to the existing code.

But the power of inline preprocessing is not limited to decompression alone. It can be applied to any type of prior processing required, as long as it produces an output that can be parsed by the external table. The directory listing is just one small demonstration of this rich capability of preprocessing in external tables. You can also use it to massage datafiles to fit a specific format, append or augment data from multiple sources dynamically—without creating any intermediate storage—or even send an e-mail when a specific text file is accessed by an external table. What you can do with inline preprocessing is limited only by your imagination.

Greg Rahn:

Before External Tables existed in the Oracle database, loading from flat files was done via SQL*Loader. One option that some used was to have a compressed text file and load it with SQL*Loader via a named pipe. This allowed one not to have to extract the file, which could be several times the size of the compressed file. As of 11.1.0.7, a similar feature is now available for External Tables (and will be in 10.2.0.5). This enhancement is a result of Bug 6522622 which is mentioned in the Bugs fixed in the 11.1.0.7 Patch Set note.

Conventional (NOAPPEND) parallel inserts available in Oracle DB 11g

Randolf Geist:

Oracle 11g obviously has added the capability to perform a conventional, non-direct-path insert in parallel.

Greg Rahn:

Parallel conventional (NOAPPEND) insert was an 11g new feature, though it seems to have escaped the new features list in the docs. It was added to support cases where parallel insert as select was desired, but the restrictions associated with direct path inserts were not desired.

ODTUG KScope 11 and Database Content

Lewis Cunningham:

My plan was to build the conference around the life cycle that a database developer works with. Since we weren’t cherry picking the content we couldn’t force anything on the schedule but the overall goal was to present topics, from beginner to expert, on Design, Coding, Maintenance and Best Practices. You can get more on what I mean by those topics at the site. I really believe we met that goal. You can also see the schedule now.
