There’s a number of things that go wrong when attempting to install Weblogic Portal 10.3.6 on MacOS that I’ve covered a few years ago in posts here and here.
To get round these issues, when installing with the generic installer you’ll need to pass these options:
java -d64 -Dos.name=unix -Dspace.detection=false -Xms1024m -Xmx1024m -jar portal103_generic.jar
Last time I needed to do this these options worked for me, although recently when I needed to do a new install I ran into this Fatal Error:
It seems the generic installer will only succeed on most recent versions of MacOS if you install with Java 6. You can chose a Java 7 install to run Weblogic with as part of the install steps.
This post describes installing with Java 6 (and this one describes the same error). I didn’t need to fake out the additional paths/libs with symlinks etc that this post does, I just needed to set Java 6 to JAVA_HOME, and then it ran through to completion ok.
The Legacy Java 6 installer for MacOS can be downloaded from here: https://support.apple.com/kb/dl1572?locale=en_US
