With the appearance of WebLogic Server as Oracle application server and the emergence of the Oracle Fusion Middleware suite, some may wonder what will be the support of their Oracle Internet Application server license, e. g. Oracle Forms and Reports services, Business Intelligence Edition, etc. As a consultant, I am often dealing with these kinds of problems and aiming to improve license benefits. In this post, I want to focus on Oracle Internet Application server licenses.

In this post, I will describe how to migrate from Oracle APEX 3.0 to Oracle APEX 4.1. I will also focus on some encountered problems as well as the new features of Oracle Application Express (APEX) 4.1.

Last week at a customer, I used DBUA to upgrade an Oracle database from 10g to 11g and the migration ran successfully. However, the day after I got a monitoring message that the diag directory is growing very rapidly.

Last week I encountered a problem while installing Oracle 11g R2 on AIX 6.1 TL06 SP2. I met all the PreReqs of the installation document, but at the end of the installation process, I got the following error message:

Error in invoking target 'agent nmb nmo nmhs' of makefile ins_emagent.mk'

Are you experiencing network access issues after a migration to Oracle Database 11g Release 2 (11.2)? If yes, you have to make sure the concerned PL/SQL packages get access to your network again. This posting will show you how.

You have recently migrated to Oracle Database 11g Release 1 (11.1) and have had some issues with so called "mutexes"? Don't worry, these nasty sounding mutexes (not mutants) can be handled quite easily as I will show in my post. But first of all, what are mutexes?
