I recently decided to install Oracle XE (Express Edition) 11gR2 on a Windows Server 2008R2 platform. That platform is x64 only. OracleXE 11gR2 is only available in a 32bit version. I thought that shouldn’t be a problem since 2008R2 has the ability to run 32bit programs. Well, that was just the first of a few eye-opening misconceptions. Once the installation was complete I upgraded the APEX environment to the latest version (v.4.1.1) following Mike Smithers posting. Much thanks to him for that.
Everything appeared to run just fine. I decided to take a look at the alert_xe.log to see what, if anything, was going on with the database. What I found was numerous messages like the following;
OER 7451 in Load Indicator : Error Code = OSD-04500: illegal option specified
O/S-Error: (OS 1) Incorrect function. !
