Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 10.2.0.1
IBM AIX Based Systems (64-bit)
Following error while installing the Oracle Database 10gR2 (10.2.0.1.0) on AIX 6.1
OUI-18001: The operating system 'AIX Version 6100.01' is not supported.
CauseError message indicates that OUI from 10gR2 installation kit is not recognizing the AIX6.1 as Certified OS.
Oracle Database 10gR2 (10.2.0.1.0) installation kit does not include AIX 6.1 as certified OS version. Because IBM's AIX 6.1 released after Oracle's Database 10gR2 (10.2.0.1.0) software is released. And hence AIX 6.1 certification details not included in already released Database 10gR2 installation kit.
